MAY 4, 2016 — A new high performance multipurpose tractor tug for Vessel Chartering LLC designed by Jensen Maritime, Crowley Maritime’s Seattle-based naval architecture and engineering firm, is powered by a pair
Looking like a teaser for an upcoming Star Trek movie, a six-minute video posted by Rolls-Royce last month lays out its high-tech vision of unmanned cargo ships and the future of shipping.
At the heart of that vision is a sophisticated, cutting-edge, land-based control center with interactive smart screens, voice recognition systems, and 3D holographic images of the ship and its equipment. An officer sits in a command chair before the “OX global wall,” which provides a worldwide overview of shipping traffic. Flying drones launched from the unmanned ship are the operator’s eyes in the sky to monitor navigation, security, weather and inspect the ship itself.
In the video, Rolls-Royce envisions a small crew of 7 to 14 people that will monitor and control the operation of a fleet of vessels across the world.
Last year, Rolls-Royce announced it would lead the Advanced Autonomous Waterborne Applications Initiative—a new EURO6.6 million project to explore, develop and design autonomous ships.
Tekes, the Finnish Funding Agency for Technology and Innovation, is providing the funding for the project, which will run until the end of 2017.
The Advanced Autonomous Waterborne Applications Initiative (AAWAI) brings together expertise from academia and industry. The participants include Finnish academic researchers from Tampere University of Technology, VTT Technical Research Centre of Finland Ltd, Åbo Akademi University, Aalto University, and the University of Turku. Besides Rolls-Royce, industry participants include NAPA, Deltamarin, DNV GL and Inmarsat.
Iiro Lindborg, Rolls-Royce’s General Manager, Remote & Autonomous Operations, Ship Intelligence, says, “unmanned and remote-controlled transportation systems will become a common feature of human life. They offer unprecedented flexibility and operational efficiency.” Lindborg says the research “aims to understand the human factors involved in monitoring and operating ships remotely. It identifies ways crews ashore can use tools to get a realistic feel for what is happening at sea.”
The video is the final stage of research that will inform the design and construction of a project demonstrator before the end of this decade.
An effective remote operations center is essential to the company’s plans to develop autonomous and remote controlled vessels.
Eija Kaasinen, Principal Scientist at VTT Technical Research Center of Finland Ltd., points out that unmanned ships doesn’t take humans out of the picture totally. “Unmanned ships need to be monitored and controlled and this will require entirely new kinds of work roles, tasks, tools and environments. The future shore control center concept has been designed by emphasizing the user experience of the human operators. By focusing on the operators’ point of view, it is possible to introduce meaningful, pleasurable and engaging new roles for the ships’ shore control center professionals.”
The research was undertaken by VTT and University of Tampere research centre TAUCHI (Tampere Unit for Computer Human Interaction) in collaboration with Rolls-Royce. It explored the lessons learned from other industries where remote operation is commonplace, such as aviation, energy, defense, and space exploration.
It uses the InnoLeap approach, a VTT and Rolls-Royce-developed initiative for concept design and presentation of academic studies in a graphic format that is based on trend and user studies, co-innovation, scenario stories and visualizations.
On April 5, in Helsinki, Finland, Rolls-Royce will reveal separate research findings, which it believes will set the direction for the development of remote and autonomous shipping.
Remote and autonomous ships are one of three elements of the company’s Ship Intelligence strategy, a portfolio of products and services – comprising health management solutions, optimization and decision support, and remote and autonomous operations – which intended to enable customers to transform their operations by harnessing the power of big data.
Rauli Hulkkonen, Tekes, Chief Advisor, thinks the project is a “fantastic opportunity to establish the Finnish maritime cluster as the world leader in maritime remote control technology.”
Esa Jokioinen, Head of Rolls-Royce’s Blue Ocean Team, says, “We are excited to be taking the first concrete steps towards making remote controlled and autonomous ship applications a reality.”
The Rolls-Royce Blue Ocean team is responsible for R&D of future maritime technologies.
Rolls-Royce is not alone in investigating the feasibility of unmanned ships. The European Commission has just completed work on project MUNIN (Maritime Unmanned Navigation through Intelligence in Networks) to develop concepts for unmanned ships. The EURO3.8 million MUNIN project focused on a dry bulk carrier concept, which typically carry cargo point-to-point on long, uninterrupted deep-sea voyages.
The goal of the projects is to reduce crew costs, lower environmental impact, and reduce the number of collisions. Human error plays a role in about 80 percent of maritime accidents.
MUNIN says that the issues of cyber attacks and pirates are a cause for concern. “However, software systems as well as ships can be designed and built providing a very high resilience against digital and physical attacks.”
HUNTING SUBS BY DRONE SHIP
Drones have been used effectively on the military side for years for surveillance, reconnaissance, and military strikes. Last month, the Defense Advanced Research Project Agency (DARPA) reported that its Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) program has designed, developed and constructed an entirely new class of ocean-going vessel—one intended to traverse thousands of kilometers over the open seas for months at a time, all without a single crew member aboard.
The ACTUV technology demonstration vessel was recently transferred to water at shipbuilder Vigor Industrial, Portland, OR, and conducted speed tests in which it reached a top speed of 27 knots (31 mph/50 kph).
The ACTUV would be used to track quiet diesel-electric submarines.
The vessel is scheduled to be christened on April 7, 2016, with open-water testing planned to begin in summer 2016 off the California coast.
Nichols Brothers Boat Builders recently completed sea trials on the second of 10,000 hp oceangoing tugs for Kirby Offshore Marine, the coastal tug and barge arm of Kirby Corporation, Houston, TX. The 136 ft x 44 ft tug, Tina Pyne, will be connected to the 185,000 bbl ocean tank barge 185-02 built by Gunderson Marine, Portland, OR.
Kirby’s newbuild plan also includes two 155,000 bbl/6,000 hp Articulated Tug Barge (ATB) units under construction at Fincantieri Bay Shipbuilding in Sturgeon Bay, WI, as well as two 120 ft x 35 ft, 4,894 hp tugs being built by Nichols Brothers Boat Builders. Each tug will be powered by two Caterpillar 3516C engines, each rated at 2,447 hp at 1,600 rev/min, with Reintjes reduction gears turning two Nautican fixed-pitched propellers with fixed nozzles. The Reintjes gears were supplied by Karl Senner, LLC, Kenner, LA. The tugs will also have two C7.1 Caterpillar generators for electrical service. Selected deck machinery includes one TESD-34 Markey tow winch, one CEW-60 Markey electric capstan, and one Smith Berger Tow Pin.
Kirby Offshore Marine is the largest U.S. operator of coastal tank barges that provide regional distribution of refined petroleum products, black oil and crude oil. Kirby grew its coastal marine transportation business through the acquisition of K-Sea Transportation Partners L.P. back in 2011 in a transaction valued at about $604 million. At that time, Kirby acquired 58 tank barges (only 54 were double hull) with a capacity of 3.8 million barrels and 63 tugs.
Already the operator of the largest inland tank barges and towboats, Kirby Corporation will grow further with the purchase of Seacor Holdings Inc.’s inland tank barge fleet for about $88 million in cash.
Under the terms of the deal struck last month, Kirby will acquire 27 inland 30,000 bbl tank barges and 13 inland towboats, plus one 30,000 bbl tank barge and one towboat currently under construction. As part of the agreement, Kirby will transfer to Seacor the ownership of one Florida-based ship-docking tugboat.
Kirby Inland Marine currently has 898 active inland tank barges and 243 towboats, with a total carrying capacity of 17.9 million barrels. The primary cargoes transported by this fleet are chemicals, petrochemical feedstocks, gasoline additives, refined petroleum products, liquid fertilizer, black oil and pressurized products.
Kirby President and CEO David Grzebinski, says “Operating primarily in the refined products trade, these assets will be complementary to our existing fleet and will allow us to continue to enhance customer service.”
TRIPLE-SCREW BOATS FOR MID-RIVER
Over the years, Rodriguez Shipbuilding, Inc.’s triple-screw towboats have won a following operating in the shallow waters where the Mississippi River meets the Gulf of Mexico. These Lugger-type vessels are designed with a distinctive aft-cabin.
Mid-River Terminals of Osceola, AR, recently took delivery of a new design towboat from Rodriguez Shipbuilding, Coden, AL. With a conventional forward-house pusher configuration, the new 70 ft x 30 ft MV/ Dianna Lynn uses the same propulsion as the Lugger tugs. This is composed of three in-line six-cylinder Cummins QSK 19 engines, each delivering 660 hp. Each engine turns a 66-inch stainless steel propeller through ZF gears with 6:1 reduction ratio. The combination gives the 1,980 hp towboat an eight-foot operating draft.
Fitted with large windows, the wheelhouse has a full 360-degree view and is set atop two accommodation decks and a half deck that also serves for bridge electronics support. This gives the towboat a 31-foot high eye-level, with full tanks, for working high barges.
Steering and flanking rudders are controlled by wheelhouse levers with mechanical shafts through the houses and connected to the hydraulic actuator valves in the upper engine room.
A set of push knees and deck winches with cheek blocks facilitates barge work. A pair of 55 kW gensets meets the boat’s electrical requirements.
Zero discharge tanks, built integral to the hull, provide storage for treated sewage and all drains. A separate tank handles waste oil.
The M/V Dianna Lynn is the fourth boat in the Mid-River Terminal fleet, all of which are Cummins powered. Owner Rick Ellis said, “We wanted the three engines for redundancy so that even if we loose an engine we still have over 1,200 horsepower.”
The new boat will be primarily involved in fleeting and harbor work, “Rodriguez did a great job and it is a great handling boat,” Ellis added.
BOUCHARD, MORAN EXPANDING FLEETS
As we highlighted last month, Bouchard Transportation’s multi-million-dollar newbuild program is winding down. The Melville, NY, owner is completing the construction of two new 6,000 hp, 310 ft x 38 ft Intercon tugs at VT Halter Marine, Pascagoula, MS. The tugs Morton S. Bouchard Jr. and Fredrick E. Bouchard will be connected to the B. No. 210 and B. No. 220. The two tank barges were the first double hull tank barges built by Bouchard,. Both were built as wire barges, but following their conversion and stretch at Bollinger Shipyards, Inc., both will be Intercon, flat deck double hulls capable of carrying 110,000 bbl of oil.
Moran Towing, New Canaan, CT, expects to take delivery shortly of a 5,300 hp/110,000 bbl ATB unit from Fincantieri Bay Shipbuilding. The Sturgeon Bay, WI, has another 8,000hp/155,000 bbl ATB unit under construction for Plains All American Pipeline, with an option for a second unit, and signed a hotly contested order for another 8,000 hp/185,000 for another earlier last month. That contract includes an option for another.
The new barge will have a capacity of 185,000-barrels with dimensions of 578 feet by 78 feet. The tug will be an 8.000-HP unit equipped with Tier 4 engines—believed to be GE Marine—to meet the latest EPA emission standards.
When complete, the ATB will operate on the U.S. East Coast and Gulf of Mexico.
“We are pleased to have this opportunity,” said Francesco Valente, FMG President and CEO. “This new contract marks an additional expansion of our product portfolio, confirms our ability to win business with new customers in a very competitive market and further consolidates our presence and reach in the U.S. market.”
“This award increases our pipeline of new construction to 10 vessels and provides additional stability to our business,” said FBS Vice-President and General Manager, Todd Thayse. “We are grateful for the confidence that our customers continue to place in our reputation for quality and the strong shipbuilding skills of our workforce.”
Conrad Shipyards, Morgan City, LA, meanwhile, is building the 80,000 bbl ATB unit for John W. Stone, as well as two ATB tugs for Harley Marine Services, Seattle, WA. Conrad Orange Shipyard in Orange, TX, recently delivered the 35,000 bbl Double Skin 315 to Vane Brothers Company. That barge was towed to New York by the Elizabeth Anne, the first in a series of eight 4,200 hp tugs being built by St. Johns Ship Building, Palatka, FL.
Designed by Frank Basile, P.E. of Entech Designs, LLC, the Elizabeth Anne Class tugboat is a close cousin to Vane’s Basile-designed Patapsco Class tugboats, 15 of which were produced between 2004 and 2009. Measuring 100 feet long and 34 feet wide, with a hull depth of 15 feet, the model-bow Elizabeth Anne utilizes two Caterpillar 3516 Tier 3 engines, each generating 2,100 hhp at 1,600 rev/min. Two John Deere PowerTech 4045, 99 kW generators deliver service power to the boat, while a third John Deere 4045 teamed with an Allison transmission drives the chain-driven INTERCON DD200 towing winch.
ROBERT ALLAN’S LATEST
Over the years, world renowned naval architectural and marine engineering firm Robert Allan Ltd. Has successfully teamed with shipyards around the world to bring new innovative tug designs to the market. Its latest is the VectRA 3000 Class Tug, a high performance VSP Tractor tug designed by Robert Allan Ltd in close collaboration with Turkish ship builder Sanmar and Voith Turbo Propulsion. The tug is designed for maximum efficiency in the performance of towing, harbor ship-handling and escorting of large ships. Performance has been verified with extensive model tests at the commencement of the design cycle. The unique propulsion arrangement features high-speed diesel engines connected to the Voith units via reduction gearboxes with integral clutches. With a bollard pull of 70 tonnes, the VectRA 3000 form can generate escort steering forces in excess of 100 tonnes. Additionally, the design has fire-fighting and oil recovery capabilities and is fully MLC compliant.
The VectRA 3000 has been designed exclusively for Sanmar to offer as one of its highly successful stable of progressive tugboats for the world market.
The first vessel in the series, the M/T Ares, built for Italian tugowner Tripmare SpA, was successfully launched at Sanmar’s new Altinova advanced shipbuilding facility this past February.
The tug has an overall length of 30.25 m, beam of 13m, depth of 5.1m, and design draft of 6.1m.
The vessels are built and classed to the following ABS notation: ✠ A1 Towing Vessel, Escort Vessel, ✠ AMS, Unrestricted Service, UWILD, HAB (WB), ABCU Fire-Fighting Vessel Class 1 Oil Spill Recovery – Capability Class 2 (>60° C) (OSR – C2).
Rather uniquely for a VSP installation, the propulsion drivetrain comprises two Cat 3516C high-speed diesel engines, each rated 2,525 kW at 1,800 rev/min, and driving Voith 32R5EC/265-2 cycloidal propellers. The engines are connected to the Voith drives through a pair of Reintjes WAF 863 gearboxes and Vulkan composite shafts, rather than using the more traditional turbo coupling. This combination is smaller, lighter and less costly than the traditional medium speed drive system. The electrical plant consists of two identical diesel gensets, each with a rated output of 86 ekW.
Crew accommodations are all located on the main deck level for optimal crew comfort. There are 4 single crew cabins plus 1 double crew cabin, each with an en-suite bathroom. A comfortable lounge/mess area and galley facilities are also in the deckhouse, with galley stores and laundry room located below the main deck forward.
All towing, ship handling, and escort work is performed using a double drum escort winch and escort rated staple fitted on the aft deck. One drum can store 710 meters of steel wire line, while the other stores 150 meters of synthetic towline. For increased operational flexibility radial type tow hooks are installed on the main deck forward and aft.
As in a traditional tractor configuration, the stern is the working end of the tug, and as such features heavy-duty cylindrical fendering with a course of ‘W’ fenders below. Hollow ‘D’ fenders protect the sheer lines and tie neatly into the ‘W’ fenders at the bow.
The wheelhouse is designed for excellent 360-degree visibility and includes overhead windows. The split type console is biased aft to ensure unobstructed visibility of the working deck (including the winch, staple, bulwarks and fenders) during operations.
CARGILL’s PUSHBOATS FOR THE AMAZON
In Brazil, the construction of a fleet of Robert Allan Ltd.-designed pushboats and barges for Cargill Transportation is nearing completion. To be used for transporting grain products on the Amazon River system, the fleet includes two shallow-draft RApide 2800-Z2 class pushboats built at INACE in Fortaleza, Brazil and 20 hopper barges built at Rio Maguari in Belem, Brazil.
Each of the two new RApide 2800-Z2 Class pushboats are 28m x 10.5m, with a minimum operating draft of 2.2m and normal operating draft of 2.5m. The two sister vessels, the Cargill Cachara and Cargill Tucunare, are designed to push barge convoys on the Amazon River system.
During the early phases of design, extensive CFD simulations were undertaken to optimize the pushboat’s hull shape to minimize total convoy resistance.
This work was completed in conjunction with extensive logistics modeling of the transportation system to optimize the selection of vessels for the desired route and to analyze operational drafts and cargo throughput at various river levels.
The pushboats were designed to ABS and Brazilian NORMAM-02 requirements and are outfitted to the highest standards.
The wheelhouse is designed for maximum all-round visibility with a split forward control station providing maximum visibility to the foredeck working area of the tug as well as to the convoy of barges ahead. Accommodation for up to 13 people is provided onboard and a large galley and mess is provided on the main deck.
The deckhouse extends aft over the main propulsion components, which comprise a pair of Caterpillar 3512B diesel engines, driving Schottel SRP 550 Z-drive units. The drives are fitted in tunnels designed to optimize flow while reducing draft. Two identical Caterpillar diesel gensets are provided in the vessel’s auxiliary machinery space located below the main deck.
The corresponding 61m x 15m box and rake barges were designed by Robert Allan Ltd. to ABS River Rule requirements. Additional extensive FEA analysis of the structure was performed in order to optimize the design for minimum steel weight while ensuring long service life during river operations. Sliding aluminum hatch covers have been supplied to ensure the cargo stays dry at all times.
MARCH 31, 2016 — The Defense Advanced Research Project Agency (DARPA) reports that its Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) program has designed, developed and constructed an entirely new class
Tucked away in southwestern Finland is Salo, a town of about 50,000, where 40 percent of all the doors for large cruise ships are produced. Antti Marine’s production facility in Salo has produced a quarter of a million doors for 300 cruise ships in just over 20 years. It takes about 10 weeks to produce a typical order of 3,000 doors. They are supplied over a period of six months, as and when the ship’s cabins are built
“We are devoted to lean thinking,” says Commercial Director Markko Takkinen. “The production time of the doors is short, as we do not want them remain in storage here.”
Antti Marine specializes in what it calls ‘“tailored mass production”—necessary because on one cruise ship there may be 150 different types of doors.
Antti Marine is not the only Finnish marine company that benefits from many of the world’s large cruise ship fleet being built in Finland.
Cruise ships also have a lot of toilets and a need for a lot of waste management systems. Finnish headquartered Evac Group has just received its biggest cruise vessel contract ever: total waste management systems for four large cruise ships plus an option to outfit an additional six vessels. The initial four-vessel contract is valued at about EURO 30 million.
Each ship will have an Evac Cleansea wastewater treatment plan, allowing operation in Environmentally Sensitive Sea Areas (ESSAs) and Special Areas (SAs), dry and wet waste treatment systems, a bio sludge treatment unit, plus vacuum collecting systems and some 3,000 vacuum toilets.
Evac also supplies its products to a wide range of users ashore and afloat. So, too, does fire protection specialist Marioff Corporation Oy, but its roots are in the marine market and it last year launched a new generation Hi-Fog 3000 sprinkler series for marine applications that replaces earlier Hi-Fog 1000 and Hi-Fog 2000 sprinkler series.
“With the launch of this new generation of Hi-Fog 3000 sprinklers, we are offering to our marine customers enhanced Hi-Fog systems with faster activation, more efficient suppression and improved passenger and crew safety,” says John Hemgård, Director of Marine Business, Marioff Corporation Oy.
The Hi-Fog 3000 sprinkler series is designed, tested and type approved according to IMO Res.A800(19) as amended in IMO Res.MSC.265(84).
Another Finnish product that really took off after its widespread adoption is ABB’s Azipod. It’s become the propulsor of choice for cruise ships and ABB is currently delivering the complete electrical power plant and propulsion systems for two new 3,300 passenger cruise ships building at Germany’s Meyer Werft. The 20.5 MW Azipod XO propulsion unit for the first of the ships recently left the ABB factory in Helsinki.
ABB has delivered, or has on order, Azipod propulsion units for about 200 vessels
Each Azipod propulsion unit takes about two months for technicians to assemble at ABB’s Vuosaari plant. Across town at ABB’s Helsinki motors, generators and drives factory, the powerful synchronous motors at the system’s core take shape over six months.
COOPERATION AMONG STAKEHOLDERS
The major driver for marine engine designers is bringing engines into compliance with emissions requirements while keeping fuel consumption and maintenance costs under control.
A new pressurized EGR (exhaust gas recovery) economizer from Alfa Laval shows how Scandinavian maritime innovation often results from a cooperation between suppliers, university departments and shipowners. It also illustrates that, for some ships, EGR may be a better means of coming into compliance with new NOx limits than the better known SCR (selective catalytic reduction).
In a project supported by the Danish Energy-Technological Development and Demonstration Program (EUDP) and developed in cooperation with Aalborg University, the EGR economizer has been rigorously tested aboard the containership Maersk Cardiff.
“As a front-runner in the pursuit of green technologies, we were keen to see what the Aalborg EGR-HPE could do,” says Ole Christensen, Senior Machinery Specialist at A.P. Moller-Maersk. “But while we were enthusiastic about the boiler’s potential, we were also somewhat uncertain as how it would handle the physical realities of EGR. The temperatures are twice as high as those of traditional waste heat recovery, and the gas pressures are far greater.”
Those concerns disappeared when the boiler was brought online with the Maersk Cardiff’s two-stroke MAN B&W 6S80ME-C9 engine in November 2014. “Not only did the boiler survive,” says Christensen, “[but also] the results we have seen during testing are very promising.”
“EGR provides Tier III NOx compliance with a very compact footprint, but compliance itself is only part of the full potential,” says John Pedersen, Business Manager, Boilers, Combustion & Heaters at Alfa Laval. “Working closely with MAN Diesel & Turbo to optimize the EGR technology, we saw additional opportunities through our expertise in marine boilers.”
In the EGR process, around 30% of the exhaust gas is directed back into the engine, which reduces the combustion temperature and thus the production of NOx. Since only the remaining 70% of the gas reaches the traditional exhaust gas boiler after the turbocharger, waste heat recovery is reduced by 30% as well.
The Aalborg EGR-HPE is a revolutionary new economizer enclosed in a pressure casing that is placed in-line ahead of the pre-scrubber sprayers in the EGR circuit.
“By moving the break point for waste heat recovery from a medium engine load down to a low load, the Aalborg EGR-HPE enables even slower steaming,” says Pedersen. “That means fuel savings that quickly pay back the economizer, offset the EGR investment and lower CO2 emissions on top of the NOx reduction.”
Positioned ahead of the pre-scrubber spray jets, the Aalborg EGR-HPE has access to much higher temperatures than traditional exhaust gas boilers. It is integrated with the conventional waste heat recovery after the turbocharger by its steam drum, which is shared with the traditional exhaust gas boiler. With the output of the traditional economizer feeding into the shared drum, the Aalborg EGR-HPE produces extremely high-quality steam with a temperature of just above 400°C, bringing the waste heat recovery system to a much higher level of efficiency.
Using the Aalborg EGR-HPE in an integrated system allows waste heat recovery to occur at lower main engine loads than possible with a traditional waste heat recovery system in Tier III operation. This creates the possibility of even slower steaming.
“The EGR economizer makes waste heat recovery beneficial at far lower engine loads, down to around 30%” says Pedersen. “This means that vessels can steam even slower, with huge fuel savings as a result.”
DUAL FUEL
B&W in MAN-B&W stands for Burmeister & Wain and the Burmeister & Wain shipyard in Copenhagen built the Selandia, the world’s first successful diesel-powered oceangoing ship. That was in 1912.
More than a century later MAN Diesel & Turbo in Copenhagen is still on the cutting edge of diesel innovation.
One beneficiary of this is TOTE Maritime which opted for MAN Diesel & Turbo dual fuel technology for its two new Marlin Class, Jones Act containerships. Both of these ships have been delivered for operation between the U.S. and Puerto Rico, burning LNG as fuel and thereby meeting all U.S. SECA emissions requirement. Each is powered by the world’s first dual-fuel slow-speed engine, an MAN-B&W 8L70ME-GI, built in Korea by licensee Doosan Engine.
The technology in the ME-GI engines wasn’t just pulled out of a hat. It is a natural development of the MAN B&W low speed electronically controlled ME family of engines. The first testing of the GI principles was carried out in 1987 and MAN Diesel
& Turbo introduced its first two-stroke ME-GI dual fuel engine series in 2011, adding the ME-LGI engine series (which can burn liquid fuels such as methanol and ethanol) in 2013.
In theory, any ME engine can be converted into an ME-GI engine, but to be recognized by a classification society as “LNG ready” an ME engine equipped newbuild will have to be designed with provision for such things as the necessary LNG fuel tanks, piping and other ancillaries.
MEDIUM SPEEDS, TOO
LNG fueling has also proved an attraction for many operators of vessels with medium speed diesels who have to operate in emissions control area.
That trend sees Wärtsilä set to deliver the 100th Wärtsilä 34DF dual-fuel marine engine from the factory in early 2016. It is part of an order for three new large escort tugs under construction for Norwegian operator Østensjø Rederi by Spanish shipbuilder Astilleros Gondan. The tugs will operate at Statoil’s Melkøya terminal near Hammerfest in Norway.
“These 100 engines do not include those delivered for land-based energy generation applications,” says Lars Anderson, Vice President, Wärtsilä Marine Solutions.
“Within its power range, the Wärtsilä 34DF has become the workhorse of the marine industry, thanks to its superior reliability and lower operating costs. It is a highly efficient engine that is also making a notable contribution to environmental compliance,”
The Wärtsilä 34DF dual-fuel engine was upgraded in 2013 with a higher MCR (maximum continuous rating) and better efficiency than its earlier version, the first of which was delivered in 2010. The upgraded version has a power output range from 3,000 to 10,000 kW at 500 kW per cylinder.
ELIMINATE THE ENGINE?
Of course, if you can eliminate the engine and switch to battery power, that gets rid of emissions issues entirely. One area where this could be possible is in certain short range ferry operations and we have already noted the E-ferry way project under way in Denmark at Søby Værft AS.
Wärtsilä, too, is eyeing this niche. In January it launched a concept for a series of zero or low emission shuttle ferries. The concept has been developed in line with new Norwegian environmental regulations for ferries, and Wärtsilä says this regulatory trend is also evident in other countries.
The ferries are designed to run entirely on batteries or in a battery-engine hybrid configuration where the fuel options are liquefied natural gas (LNG) or biofuel.
In plug-in operation, the fuel consumption is reduced by 100 percent compared to conventional installations, and all local emissions are completely eliminated. With the plug-in hybrid configuration, emissions are reduced by up to 50 percent.
The concept features Wärtsilä’s new wireless inductive charging system, which offers major benefits for typical shuttle ferry operations involving 20,000 or more departures a year because of its time and energy savings. The system eliminates physical cable connections, thus reducing wear and tear and enabling charging to begin immediately when the vessel arrives at quay.
Wärtsilä has now signed an agreement with Cavotec SA to jointly develop a combined induction charging and automatic mooring concept. It would incorporate Wärtsilä’s wireless induction power transfer into a vacuum-based automated mooring technology in which remote controlled vacuum pads recessed into, or mounted on the quayside, moor and release vessels in seconds.
FILTER PROMISES TO CUT NOX
The Exilator, an environmental filter for smaller ships, able to reduce both sulfur, carbon monoxide, NOx and noise, has been successfully tested on a Danish Maritime Authority ship. The technology has been testing over a 12-month project phase followed by a three-month practical test of the concept on the Danish Maritime Authority’s ship Poul Løwenørn. The filter’s performance has been documented by the Danish Technological Institute, and the installation and mounting of the filter has been approved by LR.
The filter has been designed for ships with engines of up to 6 MW. Current regulations don’t require the cleaning of exhaust gas from smaller ships if they already sail on marine diesel with a maximum sulfur content of 0.1%. Still, developer Exilator ApS
believes that there is already a market for the filter, as it reduces soot pollution and NOx on the ship itself and also cuts engine noise considerably — particularly attractive in the yachting sector, or expedition vessels sailing in very sensitive nature areas.
According to the test from the Danish Technological Institute, the filter reduces soot particle emissions by 99,1%, carbon monoxide by 98% and NOx by 11%. Though those tests didn’t cover the filter’s noise reduction properties but the company expects a noise reduction up to 35 dB, including low frequency noise.
Financing for development and testing was secured through the Danish Growth Fund and investment & development company CapNova.
The filter works by catalytically incinerated the soot in the exhaust as soon the ship’s engines reach exhaust temperatures above 325 degrees C. Ash is accumulated in the filter, which means that the filters must be cleaned after about 5,000 operational hours, as part of the recycling process.
The filter requires that the ship uses marine gas oil with a maximum sulfur content of 0.1%. According the test, the filter improves the ship’s fuel consumption by around 1%.
The exhaust gas, after passing through the turbo charger, goes to a muffler that removes the deep resonance. Then comes the particle filter, which also serves as an oxidation catalyst, where the soot is captured and burned – and finally the gas is led through a reducing catalyst, which minimizes NOx and NO2, before being emitted into the atmosphere.
Development is now underway in a collaboration with DTU, the Technological Institute and an engine manufacturer aimed at increasing the filter’s NOx reduction from 11% to 40% in phase 1, and to 80% in the subsequent phase 2. When this is achieved, the filter will enable compliance with IMO Tier III NOx limits.
SCRUBBERS
Shipowners face no shortage of options if they decide to use exhaust gas scrubbers to cut sulfur emissions. Recent customers for Alfa Laval’s PureSOx exhaust gas cleaning systems include Buss Shipping, which is retrofitting hybrid PureSOx systems on two 1,025 TEU container feeder ships that operate exclusively in Emission Control Areas (ECAs). Since they frequent the low-alkalinity waters between Rotterdam and St. Petersburg, as well as ports like Hamburg with zero-discharge requirements, a scrubber with closed-loop mode was a necessity.
Each ship will receive a hybrid PureSOx system with multiple inlets, connecting the main engine and two auxiliary engines to one U-design scrubber. In contrast to earlier systems with multiple inlets, the inlets will now lead into a single scrubber jet section – an advance in construction that will make the scrubber even more compact.
“The PureSOx solution was well engineered and allowed a sophisticated integration of the scrubber system into our container feeder ships,” says Christoph Meier, Project Manager, Buss Shipping. “The custom construction let us avoid major modifications inside the vessel, which together with the pre-outfitting gave us a short installation time. All those factors contributed to a competitive price.”
Though there’s no doubt that scrubbers work, they also involve a substantial investment. That led Finland’s family-owned Langh Ship to develop a scrubber of its own, the decision was made a little easier by the fact that another family-owned company has 40 years’ experience in cleaning washing waters.
The resulting product was successfully tested over an extended period on one of Langth’s own ships, the M/S Laura, and received final class approval from GL in August 2014. All of Langh’s five vessels have now been fitted with the scrubber and last year a hybrid version was installed on Bore Shipping’s M/V Bore Song.
“It has lived up to our expectations: minimum sludge handling, very clean outgoing water and in that respect minimum impact on the environment,” said Jörgen Mansnerus, VP, Marine Management at Bore Ltd.
Scrubbers could become less expensive as the result of a pilot project developed by Norwegian University of Science and Technology (NTNU) researchers Carlos Dorao and Maria Fernandino.
Called the Lynx Separator, the technology now being examined for possible use in marine exhaust gas scrubbers was originally developed for use in the natural gas industry and involves using a steel sponge along with centrifugal force to remove the fluid from a gas stream, offering a brand new solution for the gas industry.
In the Lynx Separator, wet gas flows through the separator. A tubular metal sponge spins rapidly so the liquid is separated from the gas and thrown to the side and down, allowing dry gas to stream up to where it’s needed.
The Research Council of Norway’s Innovation Program MAROFF (Maritime activities and offshore operations) has now funded a pilot project to examine the possibility of applying the separator technology to cleaning ships’ exhaust emissions from ships andetheoretical calculations and testing show promising results
BALLAST WATER MANAGEMENT SYSTEMS
Another major focus of compliance concern for shipowners is, of course, ballast water management. Needless to say, most of the major players in the Scandinavian marine equipment sectors have horses in this race. It’s just to soon to pick any winners given the fact that no system has yet gained full U.S. Type Approval.
As this was written, Norway’s Optimarin was claiming to be on the brink of the coveted approval and was pleased when the U.S. Coast Guard told manufacturers of ultraviolet (UV) based BWMS that it will not accept the Most Probable Number (MPN) testing method in its approval process. The MPN methodology evaluates organisms on the basis of “viable/unviable,” with most UV systems depositing “unviable” organisms back into the water – meaning they are still alive but cannot reproduce. The USCG said that the FDA/CMFDA test, which judges life forms as “living/dead,” must be the standard for approval.
Optimarin says the decision is good news.
The Coast Guard has told UV system manufacturers that it will not accept the Most Probable Number (MPN) testing method in its approval process. The MPN methodology evaluates organisms on the basis of “viable/unviable,” with most UV systems depositing “unviable” organisms back into the water – meaning they are still alive but cannot reproduce.
“This is a clear indication to the industry that USCG wants absolute certainty with regard to standards – they do not want living organisms deposited in their territory,” comments Tore Andersen, Optimarin’s CEO. “MPN is acceptable for IMO, but that won’t be any consolation to shipowners with global fleets that want the flexibility of sailing in and out of U.S. waters.”
He says that Optimarin, which has over 20 years of industry experience and installed the world’s first commercial BWT system in 2000, is the only UV manufacturer that is currently within “touching distance” of USCG approval.
Its technology successfully satisied the FDA/CFMDA criteria during testing last year. Further tests in other water salinities are scheduled for spring 2016, after which point approval is expected later this year.
Andersen says the system’s power is the key to its efficacy. “Each of our system lamps has a 35 kW capacity, which is huge for a UV system. That power instantly kills invasive organisms and that’s exactly what USCG wants to see,” he says

MV Veteran, 80m Ice Class Ferry
Delivered this past October by Damen Shipyards Galati, Romania, the RoPax ferry MV Veteran is built to handle the tough environment of the Arctic region. The 200-passenger vessel was designed to operate specifically in icy waters by a partnership comprised of Fleetway Inc., for the Government of Newfoundland and Labrador, and Denmark’s Knud E. Hansen.
The MV Veteran can handle 40 cm-thick floating ice at 4 knots, says Jan van Hogerwou, Damen Manager, North America. The ferry’s “rudders, hull and propellers have been strengthened and are outfitted with extra plate thickness for heavy winter conditions.”
Three MTU 16V 4000M23S engines generate 1,700 kWe, 400V, at 1,800 rev/min. The emergency genset is provided by one Volvo D16 engine generating 440 kWe 440V, at 1,800 rev/min. Its propulsion set is made up of two 1,600 kW Rolls-Royce azimuth thrusters, Electric Drive, and two 2,600 mm ice strength fixed pitch propellers.
And while the vessel was built in Romania, its very much a Canadian product, with several Canadian companies providing services for the vessel, with products including electrical equipment to fire-fighting systems.
MV Veteran has roll-on, roll-off capacity for 60 vehicles, is 80.9 m long with a beam of 17.2 m and can operate at a cruising speed of 14 knots.
The first in a two-vessel contract, the Veteran, and its sister ship the MV Legionnaire, are part of a large “lifeline” vessel replacement program being undertaken by the Provincial Government to modernize its fleet. The fleet transports over 900,000 passengers, 400,000 vehicles and 20,000 tonnes of freight with more than 50,000 arrivals and departures every year.
MV Veteran is class by ABS +A, Vehicle Passenger Ferry, Ice Class 1AA, Near Coastal, Voyage Class II, E, +AMS, HAB+, ACCU GP.
Product Director at Damen Ferries, Henk Grunstra, acknowledges that the Ice Class 1A Super certificate in the highest available for ferries. He also says the vessel has redundant systems in place for safe operation.
MV Veteran features 127 seats in the forward passenger lounge, 88 seats in the aft passenger lounge, 15 single crew cabins.
The Sally Fox, 105 ft fast ferry
Last April, a new foxy lady on the Puget Sound made her presence felt. Built by All American Marine, Bellingham, WA, the MV Sally Fox, is the first of two new ferries ordered by King County’s Marine Division. The vessel is also the first ferry to be built under the U.S. Coast Guard’s Sub-Chapter K rule, and delivered under the new 5A Space Performance Guidelines issued.
The 5A Space Performance Guidelines make it possible for a boat builder, such as All American Marine (AAM), to design and implement suitable structural fire protection in very low fire load spaces in the construction of weight-sensitive high-speed passenger vessels.
The 105 ft x 33 ft catamaran was designed by AAM, however, for its wave piercing hull design the builder called upon New Zealand-based naval architecture firm Teknicraft Design Ltd. The wave piercing hull design helps reduce drag and enhance passenger comfort.
Sally Fox is powered by twin Cummins QSK-50 tier II engines rated at 1,900 rev/min. The 250-passenger ferry operates at a service speed of 28 knots across the Puget Sound from Vashon Island to downtown Seattle.
Special attention was paid to each passenger deck’s layout in order to facilitate and streamline the boarding and disembarking process. Additionally, the new ferry features some green technologies, for example, instead of paint, the decks are covered with a peel-and-stick non-slip tread, while the exterior of the superstructure is wrapped in UV-stable vinyl.
Funded by federal grants, the new water taxi will replace the Melissa Ann, a 27 year old vessel leased to operate on the route since 2010. Its sister ferry, the MV Doc Maynard was delivered by AMM September 2015.
Baynes Sound Connector, Longest Cable Ferry
Next month, BC Ferries’ first ever cable ferry, the Baynes Sound Connector will make its long awaited debut and begin operations. Built by Seaspan’s Vancouver Shipyards, the 78.5 m ferry will accommodate 150 passengers and 50 vehicles on a 1,900 meter (about 1.9 km) route, making the ferry one of the longest cable ferries in the world.
Baynes Sound Connector will travel at a speed up to 8.5 knots between Buckley Bay and Denman Island. The ferry operates on one drive cable, and two guide cables along the route on the Baynes Sound Channel. Operator BC Ferries expects the cable ferry will help reduce operational costs, saving the company over $80 million over its expected 40-year service life; will have a smaller environmental footprint and lower fuel emissions.
While the news of the Baynes Sound Connector is exciting, the project was initially met with fears from the local community that felt a ferry operating on cables would be unsafe and wouldn’t be able to meet BC’s promise of a more efficient ferry on the run.
BC Ferries has stated that the ferry has been designed and built to safely operate in the Bayes Sound environment, which is a relatively low marine traffic area, and was tested in some of the worst weather conditions.
To further safety, it was recently announced that transit lights have been installed at both the Buckley Bay and Denman West terminals to secure safe passage for the cable ferry and other vessels in the area. A green light would indicate that the Baynes Sound Connector is docked at a terminal and boaters can safely cross the channel. A red light indicates the ferry is in transit, and it may not be safe for other vessels to cross the channels since the cables in operation may not be fully submerged.
Texelstroom, CNG Hybrid Ferry
Built by Spanish shipbuilder Construcciones Navales del Norte—La Naval, the 135m Texelstroom will offer its owner, Royal N.V. Texels Eigen Stoomboot Onderneming (TESO), a unique energy efficient vessel package that will combine a variety of green energy sources to help reduce its environmental impact when its delivered 1Q 2016.
The 1,750-passenger ferry is equipped with a hybrid propulsion system comprised of dual fuel (diesel/CNG) generating sets and a battery system, feeding the propulsion electric motors. The ferry is expected to operate mainly on the natural gas that will be storing two batteries of Compressed Natural Gas (CNG) bottles installed on the top deck.
The double-ended ferry was designed with two separate navigation bridges and two independent engine rooms. One engine room is fitted with two ABC diesel engines, each generating 2,000 kW of power; and the other engine room is fitted with two ABC dual fuel engines, also generating 2 x 2,000 kW. Each ship end will be fitted with two Rolls-Royce azimuth propeller.
The ferry, designed by La Naval in close cooperation with TESO and C-Job Naval Architects & Engineers, and classed by Lloyds’ Register, will also feature over 700 m2 of solar panels, helping the ship to be more sustainable. Additionally, according to LR, the ferry’s design is supported by the European Union’s “I.Transfer” program. The goal of the program is to make ferry transport accessible and sustainable.
The ferry will be ice class, featuring a strengthened hull to operate through winter ice, and will have a notation for Passenger and Crew Accommodation Comfort (PCAC) to ensure a safe and comfortable journey for passengers and crew.
Texelstroom will provide services in The Netherlands, between the island of Texel and the port of Den Helder. The ferry, which will also have capacity for 350 vehicles, will operate between 10 to 15 knots.
Ampere, Zero-emission Battery Powered Ferry
Norway was one of the first countries to embrace the move to alternative energies; the country was one of the earliest adopters of LNG as a marine fuel, and now it is the homebase for the world’s first battery powered electric car/passenger ferry. Built by Fjellstrand Shipyard, the 80 m long x 21 m wide Ampere produces zero emissions thanks to its Siemens’ BlueDrive PlusC electric propulsion system. The ferry does not use any fuel tanks or engines. Instead, it derives its power from its batteries which enable Norled to reduce its fuel costs by up to 60%, and save one million liters of fuel annually.
Ampere’s power system is made up of 224 Corvus Energy AT 6500 modules with a total capacity of 1.46MWH, an energy management system, a steering system, thruster control and an alarm system. The Energy Storage System (ESS) is split into four parts. Each of the vessel’s ends is fitted with a vessel mount and a shore power station—this enables and facilitates the rapid recharging of the batteries.
The innovative vessel is meant to be as environmentally friendly as possible, from the inside-out. Constructed from light-weight aluminum, the Ampere, weighs just half of what a conventional ferry would weigh. Its service life is double that of a steel hull ferry, and the vessel requires fewer drydock periods which help lower the vessel’s maintenance costs.
The Ampere is also equipped with LED lighting, high efficiency thrusters with feathering propellers from Rolls-Royce, and a HVAC system with extensive heat recovery. The ferry, which has passenger capacity for 350 and room for 120 cars, is classed by DNV-GL as 1A1- LC R4(nor), CF, C, BP, IOPP-A.
Mein Schiff 4, 99,500 grt cruise ship
Designed for the German premium-class cruise market, the 99,500 gt Mein Schiff 4 is the fourth in a series of cruise ships being built for TUI Cruises, a joint venture between TUI AG and Royal Caribbean.
Mein Schiff 4 was constructed using advanced and eco-friendly technologies according to ship builder Meyer Turku Shipyard, Finland. The ship was built to be as environmentally friendly as possible. Its expected to consume 30 percent less energy when compared to other ships its size. The cruise ship is also fitted with a combined exhaust after-treatment system, made up of a scrubber and a catalyzer, lowering sulfur emissions by as much as 99 percent, and NOx by 75 percent.
Engine power is provided by two Wartsila 12V46 diesel engines and two Wartsila 8L46F diesel engines.
The ship is 294m long x 36m wide, with an 8m draft. It features 1,253 cabins, and has capacity for 2,790 passengers and 1,030 crew members.
Mein Schiff 4’s initial itinerary included traveling through a variety of routes in the Baltic Sea to the Baltic States and in Northern Europe around Norway. This winter, the ship will travel to the Canary Islands making stops along Morocco and Mediera.
Mein Schiff 4 is classed by DNV-GL +1A1 Passenger Ship BIS Clean F(M) Fuel (991 kg/m3, -7°C, 380 cSt) LCS(DC) TMON. Sister ships Mein Schiff 5 and 6 will be completed and delivered by the Meyer Turku yard by 2017.
Samish, 144-Car Ferry
The second in a series of four Olympic Class ferries for Washington State Ferries, the 144-Car Samish, was named in honor of the region’s native Samish Indian Nation. It’s name means “giving people,” and Washington State Ferries is hoping to do just that, by giving back to the community with the addition of the Samish to its growing ferry fleet.
Delivered by Vigor Industrial, the new $126 million ferry, like its sister ship, the Tokitae, is based on the Olympic Class design by Seattle-based Guido Perla & Associates, Inc. The ferry measures 362 ft x 83 ft and has capacity for 144 cars and 1,500 passengers.
The Olympic Class, is built by a group of Washington-based companies—led by Vigor Industrial—offering the very best the state has to offer in design and production; and generating and supporting over 500 jobs in the Puget Sound.
Its superstructure was build by Whidbey Island, WA-based Nichols Brothers Boat Builders. Nichols built the superstructure for the Tokitae and will do the same for the third and fourth vessels in the series.
Olympic Class vessels were designed with passenger comfort in mind. The class provides wider lanes and more spaces for cars and trucks, additional comfort for passengers with two Americans with Disabilities Act-compliant (ADA compliant) elevators, an ADA-compliant car-deck restroom; flexible seating configurations; improved heating and ventilation; and wider stairwells and passageways.
Samish’s main propulsion is provided by two Electro-Motive Diesel (EMD) engines developing a total 6,000 hp, enabling the vessel to reach speeds up to 17 knots on its Anacortes to San Juan Islands route. Olympic Class ferries are also equipped with the latest emergency-evacuation and fire-suppression systems.
Samish and the other vessels in the Olympic Class also provide WSF with improved efficiency and better fuel consumption. Its hull design helps reduce wake, further improving fuel efficiency. The ships will replace the aging Evergreen State Class vessels which have been in operation since the 1950’s.
F.A. Gauthier, First LNG ferry for North America
Canada’s Société des Traversiers du Québec (STQ) is committed to a greener future. To that end the company invested in the construction of three LNG-fueled ferries in between 2014 and 2015, including the F.A. Gauthier, which was delivered to the operator this past summer.
Built by Italy’s Fincantieri Castellamare di Stabia shipyard, the F.A. Gauthier has the distinction of being the first LNG-fueled ferry to operate in North America. Classed by Lloyd’s Register, the ferry is fitted with an ultra compliant, low-emission, dual-fuel system from Wärtsilä.
Powered by four Wärtsilä 12v34D dual-fuel generating sets, meaning the ship can run on either Liquefied Natural Gas (LNG) or Marine Diesel Oil (MDO), the 133 m x 22 m ferry can reach a maximum speed of 20 knots on its Matane-Baie-Coreneau-Godbout route.
The ship is also equipped with Wärtsilä’s LNGPac system comprised of LNG bunkering, storage tanks, and handling equipment. Its fitted with two contra-rotating propellers, making the ferry exceptionally maneuverable.
The F.A. Gauthier’s hull is certified as Ice Class 1 and Propulsion Class 1, enabling the ship to break sea ice and handle adverse weather conditions on the Gulf of St. Lawrence. The ferry can carry 900 passengers and 180 vehicles on each trip, and is expected to transport more that 205,000 passengers and 118,000+ vehicles a year.
Viking Star, 48,000 grt cruise ship
Viking Ocean Cruises made its debut into the ocean going cruise market last year with the delivery of its highly anticipated 930 passenger Viking Star. The ship is the first of three cruise ships under construction at Fincantieri Marghera, Italy shipyard for the brand—which is a spin off of Viking River Cruises.
The goal for Viking Ocean Cruises was to bring the focus of cruising back to the destination. With that in mind, the brand decided to build a smaller passenger cruise ship, with a smarter design and providing guests with an enriching trip.
What makes the “small” cruise ship unique is that its engineered at a scale that enables the ship to have direct access into most ports, making embarkation and debarkation effectively easier and more efficient for guests. This lets passengers spend more time at each destination along the ship’s route.
The Viking Star’s design pays homage to the brand’s Nordic heritage, effectively immersing the passenger into local surroundings. Clean lines, woven textiles and light-wood help evoke the Viking spirit of discovery, according to the brand, and helps connect the passenger with nature.
The 228m long ship, which features 465 state room—each with its own veranda—has two pools, a main pool with a retractable roof, and a glass-backed infinity pool cantilevered off the stern; the ship also includes indoor-outdoor spaces for al fresco dining, large windows and skylights that further blur the light between inside and out, and a wrap-around promenade deck that pays homage to classic ocean liners.
Viking Star was also designed with the environment in mind. The ship is powered by energy-efficient hybrid engines, hydro-dynamically optimized streamlined hulls and bows for maximum fuel efficiency, onboard solar panels and equipment that minimizes exhaust pollution and meets the strictest environmental regulations.
Oscar B. 115 ft ferry, Wakiakum County
Wahkiakum County, Washington State is paying homage to one of the greatest skippers the country has ever had by naming the county’s newest ferry, the Oscar B, after him. Oscar Bergseng skippered the ferry, Wahkaikum, which was built in 1961, for 17 years.
Built by Nichols Brothers Boatbuilders, Freeland, WA, the 115 x 47 ft Oscar B is double the size of its predecessors, offering an expanded vehicle capacity.
The new ferry can carry 100 passengers and 23 cars between the Cathlamet, WA and Westport, OR terminals.
The ferry, designed by Seattle’s Elliott Bay Design Group, features a steel-hull, aluminum super-structure. Its power is provided by two state-of-the-art Cummins QLS diesel engines, each delivering 285 hp at 1,800 rev/min and couple to ZF Marine reversing reduction gears with two fixed-pitch propellers.
Oscar B meets all current U.S. Coast Guard requirements. Additionally, it features a hydraulic steering system, up-to-date electronics, a passenger lounge and ADA-accessible restrooms.
The vessel, built by Vigor Industrial’s Portland, OR, shipyard, follows towboat Crown Point, which began operations along the Columbia Snake River in May 2015.
Like the Crown Point, the Granite Point is a custom-built, environmentally-friendly towboat that was specifically designed by naval architects and marine engineers CT Marine, Edgecomb, ME, to serve Tidewater’s customers.
“Granite Point performed exactly as we wanted it to during its river trials earlier this month,” says Marc Schwartz, Maintenance & Engineering Manager at Tidewater. “We are ready for the Granite Point to team up with Tidewater’s current fleet of 16 towboats to provide our customers with the highest quality river transportation.”
Named for the granite cliff in Washington, about 20 miles southwest of Pullman along the Snake River, the towboat was built to the same specifications as the Crown Point and forthcoming sister vessel, the Ryan Point.
Measuring 102 ft by 38 ft, with a depth at full load of 11 ft, the Granite Point has a hexagonal wheelhouse with floor-to-ceiling windows on all six sides. The hexagonal design continues to the main deck, which features a galley, a media room, and a health and fitness facility.
“Tidewater understands that the ability of our crew members to cope with operational risk factors, like frequent sleep disruptions and heavy workloads, depends on their level of endurance,” says Bruce Reed, Chief Operations Officer and Vice President of Tidewater. “The responsibility for maintaining a high level of crew endurance rests with us. Therefore, all three towboats incorporate a comprehensive sound and vibration control package designed by Noise Control Engineers of Billerica, Massachusetts. The noise levels register at less than 60 decibels in the quarters during vessel operation, which is equivalent to the sound of an air conditioner.”
“When you are in the wheelhouse, which is three decks above the engines, you would really need to concentrate to hear the engines at all,” says Brian Fletcher, Tidewater Port Captain who piloted the Granite Point through river trials.
“You couldn’t ask for a quieter tug, nor a better tug in tight situations. It turns on a dime.”To meet the challenges of maneuvering barges through swift-moving currents, high winds, and eight navigation locks along the CSR System, CT Marine designed an enhanced steering system utilizing four main steering and four flanking rudders. Coupling the steering system with two Caterpillar 3516C Tier 3 engines, the design team was able to increase the margins of safety and efficiency.
“The Granite Point can ‘get up and go’,” says Josh Nichols, Assistant Port Captain, “but there is an ease and steadiness to it.”
“The up-front work paid off,” says Bob Curcio, Tidewater CEO. “The vessels are fuel-efficient, ecologically-responsible, and are giving our Captains and crews exactly what they’d asked for.”
“We are proud to have worked with Tidewater on Granite Point. Like its sister ship Crown Point, this vessel sets new standards for future towboat design. It will serve our community well for decades to come,” says Corey Yraguen, Vigor Executive VP of Fabrication.
TECHNICAL PARTICULARS
The Granite Point is powered by two Caterpillar 3516C EPA Tier 3 certified diesel engines each producing 2,240 BHP at 1,600 RPM. The engines drive two 92″ x 100″ fixed pitch, stainless steel propellers through CT28 Kort Nozzles. The vessel is capable of a service speed of 8 knots.
Electrical power is provided by two C7.1, Tier 3 generators, rated at 480 V, 200 kW at 1,800 RPM. The generators are controlled through an automatic transfer system that ensures the vessel will recover from a generator power loss in less than 30 seconds.
Deck machinery includes seven Patterson WWP 65E-7.5, 65 ton electric deck winches, with pilot house remote operation and local push button control stations on the main deck. Each winch has Samson 1 3/8″ Turbo 75 Synthetic Line.
To minimize power usage, variable frequency drives were used in all major rotating machinery applications and LED lighting was employed in both interior and exterior lighting applications.
The vessel is fitted with a Kidde NOVEC 1230 fire suppression system. Centralized fire detection and alarms cover both the machinery spaces and accommodations.
