AUGUST 9, 2016 — Jork, Germany, headquartered shipowner Reederei H.-P. Wegener is reporting major fuel cost savings using Alfa Laval PureSOx exhaust gas cleaning systems. The company’s four container feeder vessels, include
MAY 23, 2016 — The Exhaust Gas Recirculation (EGR) systems in five very large ethane carriers (VLECs) will incorporate PureNOx Prime, Alfa Laval’s new PureNOx solution for water treatment. The 85,000 cu.m
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
DECEMBER 23, 2015—Gibraltar-based ship repairer Gibdock reports that a surge in bookings by new and repeat customers into the first two quarters of 2016 will propel it in the first half of
Buss Shipping operates 20 feeder ships and has a strong chartering business. To meet the requirements of today’s charter market, the company is focusing on the sustainable modernization of its existing fleet.
As a key step in this process, hybrid Alfa Laval PureSOx systems will be retrofitted on board the vessels Condor and Corsar. Both 1,025 TEU feeder ships operate exclusively in Emission Control Areas (ECAs).
Since they operate in 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.
“The hybrid PureSOx systems on the Condor and Corsar will provide emission compliance with maximum flexibility and fuel economy,” says Torben Kölln, Managing Director, Buss Shipping. “This will uphold the competitiveness of our offer to charter customers.” Custom engineering for the ideal solution
The Condor and Corsar will each 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.”
For the engineering of the PureSOx systems, Buss Shipping GmbH & Co. KG cooperated with SDC Ship Design & Consult GmbH.
Detailed engineering was handled by the shipyard German Dry Docks GmbH & Co. KG, which will install the systems following deliveries by Alfa Laval in January and February 2016.
“The work between Buss Shipping, Alfa Laval, the shipyard and the engineering consultant has been smooth and productive,” says Mark Aarbodem, Project Manager at Alfa Laval. “Alfa Laval’s scrubber design and project management experience, together with the strong cooperation from the rest of the team, will ensure a reliable outcome for Buss Shipping.”
“All parties have worked together to arrive at a compliant solution that will benefit our charter operations,” says Mr. Kölln. “Rather than paying for expensive fuel, our container vessels will be able to serve charter customers at a competitive price – while still retaining our margins.”
It covers five vessels operated by ship management major Norbulk Shipping and owned by Netherlands headquartered shipping group Vroon.
The contract gives the shipyard a sizable debut in specialized EGS work. With all five ships also undergoing special survey drydocking, the job is the Gibraltar yard’s largest single assignment in 2015. It is the first series retrofit EGS win for any Southern European yard.
“We are the first shipyard in the region to win a major exhaust scrubber project,” said Gibdock Managing Director Richard Beards. “Our ideal location means that we are always attractive for owners considering this area. Gibdock’s competitiveness, high quality workmanship and on-schedule redelivery has led to this breakthrough deal, which opens a new chapter in the industry’s EGS installation work options.”
Gibdock’s workload included the 37,500 dwt product tanker Great Eastern, the third of the five Norbulk vessels being fitted with PureSOx main engine, auxiliary engine and boiler EGS units from Alfa Laval. The hybrid PureSOx system removes over 98% of SOx emissions from exhaust gases and up to 80% of particulates.
EGS installation work onboard Great Eastern included 90 tonnes of newly fabricated steel, the laying of 12,386 m of electrical cabling and 1,134 m of GRE pipes involving 800 flanges and elbows.
Special survey work included a hull washing, spot grit-blasting and coating job, overhauling of sea valves, propeller withdrawal, bonding of stern seals, rudder clearances, bow thruster overhauling, windlass winch bearing renewal, overhauling of boiler safety valves,pipeworks, insulation works and various other routine dry-dock works. These tasks took place at the same time as the EGS installation, with the ship redelivered on schedule and on budget in 20 days.
Mr. Beards said the time taken for redelivery to Norbulk of subsequent ships has been shortened as projects have progressed.
To optimize EGS retrofit processes, Gibdock undertakes prefabrication for smaller blocks in its workshops, with transfer to the yard’s Pad 1 area, completed in 2014, allowing further structural and assembly work to be completed alongside Drydock 1 in a timely fashion for drydocking.
“Pad 1 was pivotal in optimising workflow,” said John Taylor, Gibdock Operations Director. “No other regional yard has a comparable purpose-built zone for EGS foundation and structural work before vessels arrive.
“This has been an intense collaboration, involving different Gibdock departments, naval architects, the Norbulk project team, Alfa Laval, and our electrical and piping systems subcontractors. Optimised planning, materials purchasing, equipment deployment and job sequencing for EGS work are now part of Gibdock’s competitive advantage.”
“In the more than seven years that Shell has held leases in the Chukchi, it has only recently been allowed to complete a single well. What we have here is a case in which a company’s commercial efforts could not overcome a burdensome and often contradictory regulatory environment,” says Murkowski. “The Interior Department has made no effort to extend lease terms, as recommended by the National Petroleum Council. Instead, Interior placed significant limits on this season’s activities, which resulted in a drilling rig sitting idle, and is widely expected to issue additional regulations in the coming weeks that will make it even harder to drill. Add this all up, and it is clear that the federal regulatory environment—uncertain, ever-changing, and continuing to deteriorate—was a significant factor in Shell’s decision.”
Murkowski made the point that just because the U.S. has created a difficult environment for offshore drilling in the Arctic, it doesn’t mean other countries have. “Development in the Arctic is going to happen—if not here, then in Russia and Canada, and by non-Arctic nations,” says Murkowski. “I personally believe that America should lead the way. The Arctic is crucial to our entire nation’s future, and we can no longer rely solely on private companies to bring investments in science and infrastructure to the region. As the Arctic continues to open, we urgently need to accelerate our national security investments in icebreakers, ports, and other necessities.”
Some Congressional opponents of Arctic drilling applauded Shell’s move. Senator Jeff Merkley (D-OR) called offshore Arctic drilling “unacceptable” and irresponsible. Rep. Jared Huffman (D-CA) went so far as to introduce the Stop Arctic Ocean Drilling Act of 2015, which would prohibit new or renewed oil and gas leasing in the Arctic Ocean Planning Areas of the Outer Continental Shelf.
But this should probably be viewed more like a pause as opposed to a full stop. A more favorable regulatory environment for Arctic offshore drilling could develop if a Republican is in the White House in 2017 backed by a Republican-controlled Congress. Additionally, cheap oil and gas should also increase consumption and eventually lead to higher prices and make Arctic drilling more economically attractive.
Shipyards, naval architects team on projects
Portland, OR, headquartered Vigor Industrial, the largest shipyard group in the Pacific Northwest with 12 facilities in Alaska, Washington, and Oregon, had bolstered its capabilities in anticipation of an increased workload. It added an 80,000-ton lifting capacity dry dock to enhance its ship repair and maintenance capabilities and merged with Kvichak Marine Industries, Seattle, WA, to add capabilities in new aluminum vessel construction. Vigor had supported Shell’s earlier efforts in Alaska, including the activation of the drilling barge Kulluk, and more recently repaired the damaged icebreaker Fennica.
Vigor is part of a vibrant Washington State maritime cluster that includes logistics and shipping, fishing and seafood, and shipbuilding and repair. According to a recent economic impact study, generated 148,000 direct and indirect jobs and directly creates $15.2 billion in gross business income and has a total impact of $30 billion on the state’s economy.
Back in March, Vigor “christened” its dry dock Vigourous with work on the cruise ship Norwegian Star and followed that up with repairs to the USNS John Glenn and USNS Montford Point. Now Vigor will turn its attention to completing the third Olympic Class 144-car ferry for Washington State Ferries and look forward to building the fourth in the series, which recently received $122 million in funding by the state legislature. There’s plenty of more coverage on the ferry market in this issue, including Seattle-based Elliott Bay Design Group’s support of ferry projects for the New York City Department of Transportation and Texas Department of Transportation.
Special launch system
Designed by Seattle-based naval architectural firm Guido Perla Associates, Inc., the144-car ferry is a joint construction effort between Vigor and neighboring Nichols Brothers Boat Builders, Whidbey Island, WA. Nichols Brothers Boat Builders has been contracted to build the superstructure for the first three Olympic Class ferries. Nichols Brothers Boat Builders has used a new track and dolly system developed by Engineered Heavy Service (EHS), Everett, WA, for transferring the ferry superstructures it on to a barge for transport to assembly with the hull at Vigor Fab in Seattle.
That same transfer system is pictured on this month’s cover, to launch the ATB tug Nancy Peterkin, the first of two 136 ft x 44 ft x 19 ft sister ATB tugs being built for Kirby Offshore Marine.
This past May, Gunderson Marine, Portland, OR, had launched the Kirby 185-01, a oil & chemical tank barge.
The Nancy Peterkin’s sister ATB tug, the Tina Pyne, is set for launch this December.
The EHS launch system moved the ATB from the shipyard to the launch ramp. General Construction provided two floating cranes to assist in the final lifting of the vessel, shuttling it to deeper water.
The vessel was towed to Everett, for lightship, stability testing and fuel transfer. Following this the tug will be towed to Nichols Brothers outfitting pier in Langley, WA, located across the Puget Sound from Everett, WA, for final outfitting, dock and sea trials before its final delivery.
Used for vessels greater than 1,000 tons, the new launch system significantly increases the displacement and draft of the vessels that Nichols Brothers can haul and launch in the future. Currently the shipbuilder is engineering to install ridged buoyancy tanks to the side of the launch frame, eliminating the need for the floating cranes in the future.
Nichols Brothers followed up the launch with the signing of a construction security agreement with Kirby Offshore Marine to build two new 120 ft x 35 ft x 19 ft-3 in tugs. Each tug will be powered by two Caterpillar 3516C, 2,447 bhp at 1,600 rev/min main engines with Reintjes reduction gears turning two NautiCAN fixed pitched propellers with fixed nozzles. Karl Senner, Inc., Kenner, LA, supplied the reduction gears for the vessel. These vessels 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.
Keels will be laid for both vessels this fall with delivery of the first vessel scheduled for May 2017 and the second vessel is scheduled for delivery in November 2017.
Jensen Maritime Consultants, Seattle, the naval architectural and engineering arm of Crowley Maritime, will provide the ABS Class and functional design for the tugboats. These tugboats will carry an ABS loadline, compliant with USCG, as required at delivery.
Nichols Brothers is currently working on the second ATB Tug for Kirby Offshore Marine.
Nichols Brothers spokesperson Lacey Greene says the shipyard has just begun construction of the American Samoa 140 ft Multi-Purpose Cargo/Passenger Ferry, and next year will begin construction on the superstructure and final assembly of the WETA 400-passenger high speed catamarans.
“The vessel construction boom in the Pacific Northwest has impacted the economy in so many different ways,” says Greene. “Specific to our location our community is flourishing. Nichols Brothers is the largest private employer on Whidbey Island in Washington State and employs 300 men and women. We foresee the economic boom expanding even further; the tug market is strong in all aspects, from ATB tugs, tractor Tugs, to line tugs. We also see the passenger vessel industry sector thriving, and we predict additional passenger only high-speed ferries coming down the pipeline as well as leisure vessels.”
Jensen Maritime is also providing construction management services for the Crowley product tankers under construction at Aker Philadelphia Shipyard. It’s also been busy working on developing LNG bunker barge concepts and recently received approval from ABS for a 452 ft-long ATB version.
Engineering consultant Art Anderson Associates, Bremerton, WA, has been increasing its staff and supporting the development of passenger-only ferry service in Puget Sound. Art Anderson’s Patrick R. Vasicek, PE, LEED AP, will be on hand at the Marine Log FERRIES 2015 Conference & Expo in Seattle to discuss, “An Exportable Life Cycle Assessment Tool for Determining Sustainable Visibility of Passenger-Only Ferry Routes and Systems.”
Ballast water treatment solution
Seattle-based naval architectural and engineering consultancy Glosten reports that Marine Systems Inc. (MSI) has delivered a pair of Ballast Treatment System Deck Modules, designed for tank barge and ship operations.
MSI turned to Glosten to develop the design in response to requests from vessel operators and the first of a kind modular ballast water treatment units combine expertise from Glosten, MSI and Alfa Laval, which provided PureBallast 3.1 treatment systems, Filtrex high efficiency filters, and expertise from hundreds of ballast water management system installations.
The resulting modules, built at the Foss Seattle Shipyard, complete with lighting, ventilation, and integrated controls, were shipped ready for “plug-and-play.”
Each Ballast Module packs a treatment capacity of 1,000 m3/hr within a 20-foot shipping container footprint and is ABS and U.S. Coast Guard approved for hazardous area installations.
Using the module reduces the technical demands on busy shipyards. Rather than juggling independent components and vendors, shipyards can instead focus on fabricating a few well-defined interfaces and foundation system. Each purchased module comes pre-approved by USCG and ABS, is fully tested prior to shipment, and includes integration support from MSI and Glosten engineers.
“The demands of the vessel operator drove this design,” says Kevin Reynolds, Principal at Glosten. “Doing this as a manufactured product ensures that we get it right, every time.”
