Electric & Hybrid: Call me Ishmael, no longer

Call me Ishmael. Melville’s famous opening line in his novel Moby Dick refers to an outcast and could once have been the motto of the hybrid and electric marine industry. There were a number of projects where hybrid and full electric drivetrains were prototyped and they worked well…for a while. The limitation was always the battery technology, where lead acid batteries were just not suited to this type of application. As a result, these projects and technologies were “interesting” with “lots of potential” but not a serious technology for the mainstream marine industry.

The advent of lithium ion batteries has fundamentally changed the value proposition for the hybrid and electric drivetrain. These batteries are smart, durable and have a lifetime that will ensure the customer is able to achieve their targeted Return on Investment (ROI). As a result, the hybrid and electric drivetrain has come of age.

To date, Corvus Energy has deployed over 30 MWh of its Lithium Polymer battery-based Energy Storage Systems (ESS) on over 45 projects. These vessels include large and small ferries, offshore supply vessels (OSVs), tugboats, research vessels, luxury superyachts and port cranes. Only two of these applications are for full electric ferries, the remainder are all hybrid vessels, but a common element is that both types of drivetrains make the vessel more efficient, as well as more environmentally sustainable.

Of course an ESS cannot create energy, but only stores it. The ESS therefore enables the vessel to use the cheapest energy available and shift it in time to the point where it is most cost effective. For a full electric this means the ESS is charged from shore using low cost energy and eliminates completely energy generated by costlier, on-board generators. For hybrids, it moves energy from the efficient portion of the generator’s load curve and replaces energy that would have been generated on the less efficient portion of the generator’s load curve.

Full Electric Drivetrains
At one time the round trip efficiency of an ESS was at 70% or less and the energy density was also not very high. This meant an ESS required a LOT of space on a vessel and did not actually store that much energy. The round trip efficiency on the Corvus ESS is now over 95% and the energy density is high enough that a space the size of a 20-foot container can store 650 kWh. This means that an ESS can now deliver enough power and energy to make a full electric drivetrain cost effective. Even with these improvements, full electric drivetrains still work best for applications where the duty cycle is relatively short such as a ferry with a route that is less than an hour between charging points. The 120-car Ampere ferry in Norway, for example, has a route which crosses Sognefjord between Lavik and Oppedal in 20 minutes and then recharges for 8 minutes from a shore-based charging station which uses the grid and another, smaller Corvus ESS to deliver a large amount of power into the vessel’s ESS in a short period of time. The shore-based charging station then recharges from the grid for about 48 minutes until the ferry returns.

The ferry operator, Norled, has other, diesel-fueled vessels on this route and based on a comparison has estimated that the Ampere is saving over 1 million liters of expensive, ultra-low sulfur diesel fuel per year. It is also saving 90% of the maintenance cost of the diesel engines and 100% of the cost of the NOx emissions, which are taxed in Norway. Norled is now looking at expanding the operating hours of the Ampere each day and is examining other routes it operates to determine if they could benefit from a fully electric ferry.

Hybrid Drivetrains
A hybrid drivetrain consists of a either a diesel or LNG engine as the prime generator for the vessel and supplements this engine with an ESS. The ESS is able to charge with energy produced when the engine generator is operating in its most efficient range and then, when the engine generator would be operating in its inefficient range, the engine is shut off and energy is extracted from the ESS to operate the vessel.

A harbor tug is a good application for a hybrid drivetrain. It will typically spend up to 25% of its time sitting and waiting for a call to push a ship. While in this mode, the vessel needs to maintain its position and run its hotel load. The engine is too large to idle and provide power just to the hotel load and so the engine drives its thrusters in opposite directions, thereby keeping the vessel in position but “boiling water” and wasting fuel. With a hybrid system, the engine is turned off and the ESS is used to periodically operate the thrusters to keep the vessel in position, and also serving the hotel load. When the ESS gets to the minimum state-of-charge, the engine is started to charge the batteries, serve the hotel load and run the thrusters. Depending on the hybrid drivetrain configuration, the ESS can also be used to supplement the engine when the tug is pushing or pulling a vessel to get it into position. When the batteries are charged the engine is turned off. An ESS on a tug can save up to 25% on fuel and emissions, as well as reducing maintenance on the engine(s).

An ESS is also very effective to replace the operation of a second engine that is running in spinning reserve to provide emergency power in the event the prime mover generator fails during a critical operation. On the Scandlines ferries in Denmark and Germany they only operate one generator during crossing and use their ESS for spinning reserve. Scandlines have identified 13% reduction in fuel and emissions and a 45% reduction in generator maintenance.

Likewise, Offshore Supply Vessels (OSVs) in the North Sea can use an ESS for spinning reserve during Dynamic Positioning (DP) operation, where the vessels have to be kept stationary when servicing floating oil and gas platforms. DNV-GL has now approved ESS for DP operations. Eliminating the operation of an additional generator used in spinning reserve has the potential to save fuel, emissions, maintenance and even the capital cost of the additional generator.

 

Key Benefits
The key benefits from an ESS include:

  • Reduced generator hours/generators running in efficient range
    • Reduced fuel consumption
    • Reduced emissions
    • Reduced maintenance
  • Improved capital management
    • Reduced number of generators
    • Reduced size of generators
    • Generator life extension – operation in efficient range provides longer lifetime
  • Emergency backup
    • Spinning reserve
    • Emergency and auxiliary backup
  • Passenger/crew comfort
    • Reduced noise
    • Reduced vibration
    • Reduced fumes
  • Reduced emissions
    • GHG’s
    • Reference air emissions – NOx , SOx , PM
  • Improved performance
    • Better ramping on LNG engines
    • Instant response to throttle
    • Better transient load management

The Future is Now
No longer the elusive white whale, cost effective and proven hybrid electric propulsion has arrived and is here to stay with early adopters now reaping the benefits. An ESS helps owners make their vessels more efficient by helping them manage the operating and capital costs of their vessels, while also making these vessels more reliable and environmentally sustainable. No longer outcasts like Ishmael, the electric and hybrid marine industry has proven the value proposition for electric drivetrains and energy storage. Corvus Energy’s ESS is a key piece of these innovative hybridization projects for commercial vessels, which are fundamentally changing these marine markets. Where once there was only a potential for these benefits, Corvus Energy has the ESS technology, people and experience to make them real.

Atlantic Coast: A time of renewal

If you were at a seaport along the U.S. Eastern Seaboard, more than likely you would be able to spot the distinctive blue “V” logo of the Vane Brothers Company on at least one tug in the harbor. The privately held marine transportation company has been serving the U.S. East Coast for more than 100 years, now handling chemical and petroleum products on its double-skin tank barges in seven ports from New York to Jacksonville, FL.

Under the steady guidance of C. Duff Hughes, the third generation of the Hughes family at the helm of the company, Vane Brothers, headquartered in Baltimore, MD, has been aggressively growing its fleet of 120 tugs and barges. Since 2008, Vane Brothers has been adding a series of 3,000-hp, Sassafras Class Articulated Tug Barge (ATB) tugs. Just last month, Vane Bros. ordered the 15th, 16th, and 17th of the class, all of which have been ordered from and built by Chesapeake Shipbuilding in Salisbury on the Eastern Shore of Maryland.

VaneFort SchuylerThe latest in the series delivered by Chesapeake Shipbuilding is the Fort Schuyler, the eleventh in the class. Its sister tug, the Kings Point, was delivered in April this year.

The tugs have been very popular with the company’s crews. Vane Brothers Senior Port Captain Jim Demske, says, “The crews on these tugs particularly like the high quality of the tugs’ construction and layout. The ergonomic arrangement of the pilothouses and engine rooms contribute comfort and safety. The power from the Caterpillar engines and the performance from the Twin Disc reduction gears all contribute to the great handling of these tugs, which is especially appealing to the operators. The new Simrad Solid State Halo radars and touch-screen electronics are some of the finest in the industry and also make life on these tugs better.”

Measuring 94 feet long and 32 feet wide with a hull depth of 13 feet, the Fort Schuyler is similar in most respects to the previous 10 tugs built for Vane by the shipyard.

The vessel is equipped with twin Caterpillar 3512 Tier 3 main engines producing a combined 3,000 horsepower, and operates with a single-drum hydraulic towing winch from JonRie Intertech, Manahawkin, NJ.

“Soft-core” panels and heavy, fire-rated doors are used throughout the boats, offering the crew a safer and quieter living environment.

“Vane Brothers and Chesapeake Shipbuilding continue to have a very strong relationship,” says Demske. “The next tug to be launched in coming weeks will be the Fort McHenry, followed by the Fishing Creek.” Demske says the names of the other tugs have yet to be announced.

The Fort Schuyler, like the Kings Point, has joined Vane Brothers’ fleet based in New York. The two vessels are named for the campuses of SUNY Maritime College in Fort Schuyler, NY, and the U.S. Merchant Marine Academy in Kings Point, NY.

In addition to the 3,000-hp tugs coming from Chesapeake Shipbuilding, there are two 4,200-hp tugs under construction at St. Johns Ship Building in Palatka, FL, for delivery in 2016, with two more under contract.

VANE ADDS NEW BARGES, TOO
According to Vane Brothers, three 35,000-barrel barges and four 55,000-barrel barges (including the 509A asphalt barge) have been delivered in the last 10 months, with another 55,000-barrel barge expected before the end of the year. These have come primarily from Conrad Shipyards in Orange, TX, and Amelia, LA, as well as Jeffboat in Jeffersonville, IN.

New and current mariners at Vane have a variety of training opportunities available to them, both formal and informal. According to Vane Brothers spokesman Blaise Willig, the company has supported many vessel-based employees this year as they receive instruction to help them be more effective at their current jobs and contribute to their future advancement. Vane is a Partner Company in the Workboat Academy’s Workboat Program. And, as a result of Person in Charge (PIC) Barge training this year at the Maritime Institute of Technology and Graduate Studies (MITAGS) in Linthicum Heights, MD, former Vane Deckhands have become highly qualified Tankermen now assigned to Vane barges. Vane’s training efforts and commitment to promoting from within help to ensure that its vessels are manned with professionals who meet and surpass the highest standards in the industry.

NEW ATB TUG LAUNCHED FOR BOUCHARD

Early last month, the Moss Point Marine shipyard of VT Halter Marine, Inc., launched the M/V Morton S. Bouchard a 6,000hp, twin-screw Articulated Tug Barge (ATB) tug for Bouchard Transportation, Inc., Melville, NY.

The ATB tug is one of two sister vessels being built under a two-vessel contract signed in August 2014. Morton S. Bouchard and sister vessel Frederick E. Bouchard each measure 130 feet by 38 feet by 22 feet and is classed by ABS as +A1 Ocean Towing, Dual Mode ATB, USCG Subchapter C. On completion, both tugs will be equipped with an Intercon Coupler System. Deliveries are expected in January and May 2016, respectively. The vessels will enter into Bouchard Transportation’s fleet service in New York, NY.

This most recent launch follows the September launch from the Moss Point shipyard of another ATB tug for Bouchard, the 10,000 hp M/V Donna J. Bouchard.

Also equipped with an Intercon Coupler, Donna J. Bouchard, is classed by ABS as +A1 Towing Vessel, Dual Mode ATB, USCG Subchapter M. She will be paired with barge B.No.272, which is currently under construction at VT Halter Marine’s Pascagoula, MS, shipyard to comprise the second ATB unit built for Bouchard Transportation as part of its major expansion program.

“Bouchard Transportation Co. Inc. is happy to announce yet another successful launching of a state of the art ATB tug built by VT Halter Marine. The launching of the M/V Morton S. Bouchard Jr. is a special event within the Bouchard Family, for the vessel is named after the father of President/CEO, Morton S. Bouchard III, who wanted his father’s name to always remain on the waterfront for which he dedicated his entire fife to. The original tug, Morton S. Bouchard Jr., which was also built by Halter, was earlier renamed as The Bouchard Boys and continues to operate with Bouchard Fleet,” says Morton S. Bouchard III President and CEO, Bouchard Transportation.

“The successful launching of both vessels, the M/V Morton S. Bouchard Jr. today and the M/V Donna J. Bouchard in September is an indication of the commitment to the continued relationship with Bouchard Transportation,” says Jack Prendergast, CEO, VT Halter Marine.

MoranNEW ATB TUG FOR MORAN
Moran Towing has newbuild programs underway at Washburn & Doughty shipyard in East Boothbay, ME, and Fincantieri’s Bay Shipbuilding in Stugeon Bay, WI. Its newest ATB tug, Leigh Ann Moran, recently completed her sea trials in Sturgeon Bay. The 121 ft x 36 ft tug was christened in late September by her namesake, Leigh Ann Engibous, wife of long-time Chevron employee Bill Engibous.

Also under contract at Bay Shipbuilding are the 121 ft x 36 ft ATB tug Barbara Carol Ann Moran and a 110,000 bbl double-skin tank barge, which are due for delivery in the second quarter of next year.

Meanwhile, Washburn & Doughty have contracts for six 6,000 hp Z-drive harbor tugs for the New Canaan, CT-based tug company.

MCALLISTER PUBLISHES 150th ANNIVERSARY BOOK
Last year, McAllister Towing & Transportation Co., New York, NY, celebrated its 150th anniversary of providing marine transportation, towing and harbor services. The beautifully bound hard cover book recounts the history of the five generations of the McAllister family and the tugboat business. The company was founded by James McAllister, who arrived in New York City following a shipwreck and soon bought his first sail lighter in 1864. From those humble beginnings, the distinctive red and white striped funnels of McAllister tugs can be seen from Portland, ME, to San Juan, PR.

McAllister currently has one ABS-classed 5,000-hp Z-drive reverse tractor tug on order at Eastern Shipbuilding Group, Panama City, FL. The word on the street is that the company is in serious discussions with another shipyard regarding the construction of at least two other harbor tugs.

Eastern Shipbuilding also recently launched the H. Douglas M, the first in a series of four 5,150 hp escort tugs for Bay-Houston Towing. The 80 ft x 38 ft tug is based on a Z-Tech 2400 Class design by Robert Allan Ltd. Delivery of the escort tug is scheduled for early 2016.

The same design is being built by Eastern Shipbuilding for a series of four tugs for Suderman & Young. G&H Towing is the owners’ onsite representative and agent during the engineering, construction, and delivery for both Bay-Houston and Suderman & Young Towing.

WIND FARM VESSEL TAKES SHAPE
In Warren, RI, the first U.S.-flag wind farm vessel is taking shape at Blount Boats, Inc. Blount Boats President Marcia Blount says the 21-meter aluminum catamaran will be ready for delivery in April 2016.

Rhode Island Fast Ferry will operate the boat for Block Island Wind Farm in Rhode Island. The five turbine wind farm, the first commercial wind farm in the U.S., is expected to be up and running by the fourth quarter of next year.

The catamaran is a Crew Transfer Vessel (CTV) based on a design licensed from South Boats (IOW), Isle of Wight, the U.K., one of the leading designers and manufacturers of wind farm vessels in Europe. South Boats IOW has designed and built some 85 CTV’s for the European offshore wind sector.

Blount Boats is eyeing the progress of offshore wind energy closely, says Marcia Blount.

Blount Boats also is building a passenger vessel for Chicago’s Shoreline Sightseeing. Shoreline Sightseeing provides guided architecture tours on the Chicago River, as well as classic tours on Lake Michigan and “Brew Cruises” and wine-tasting cruises.

NEW BOATS FOR CIRCLE LINE
About a 20-minute ride from Warren, RI, is the shipyard of Gladding-Hearn Shipbuilding, a Duclos Corporation in Somerset, MA. Known for their construction of aluminum, multi-hull vessels based on IncatCrowther designs, the Massachusetts shipbuilder is actually building three all-steel 600-passenger vessels for Circle Line Sightseeing Yachts, Inc., New York, NY. The 165 ft x 34 ft were designed by DeJong & Lebet, Jacksonville, FL. Those boats are due for delivery in the spring.

It’s also building a 493-passenger ferry for Hy-Line Cruises due for delivery in 2016.

One of the latest deliveries from Gladding-Hearn is the Manatee, a 28-knot Chesapeake Class launch and the first in a new generation of the popular, mid-size pilot boats for the Tampa Bay Pilots Association.

The boat continues a successful partnership between Gladding-Hearn and C. Raymond Hunt Associates, Inc., New Bedford, MA.

The Somerset, MA, shipyard introduced the Chesapeake Class pilot boat in 2003. Since then, 15 have been delivered to pilot associations throughout the U.S.

The latest improvements incorporate the performance benefits of Volvo Penta’s IPS2 inboard propulsion system.

“The IPS2 system was created to improve the performance and the arrangement of planning hulls like our pilot boats,” says Peter Duclos, the shipyard’s president. “This new generation of Chesapeake launches, named Chesapeake Class MKII, is equipped with the IPS2 pods, which provide what pilots have been asking for: higher speeds, lower fuel consumption, and more comfort.”

With a deep-V hull designed by C. Raymond Hunt & Associates, the all-aluminum pilot boat measures 52.7 ft overall, with a 16.8-ft beam and a 4.5-ft draft.

It is powered by two Volvo Penta D11, six cylinder, EPA Tier 3 diesel engines, each producing 503 bhp at 2,250 rev/min. Each engine is connected to a Volvo Penta IPS propulsion pod, which is fitted with dual forward-facing, counter-rotating propellers and integrated exhaust system, and Volvo Penta’s integrated EPS electronic steering and control system.

The EPS control system and three-axis joystick increases the boat’s overall maneuverability alongside a ship and when docking, says Duclos.

The financial incentive for the Tampa Bay pilots to optimize fuel economy, vessel handling and comfort led the shipyard to install a Humphree Interceptor automatic trim- optimization system.

“The combination of the Volvo Penta IPS system and the Humphree interceptors gives the pilots higher speeds and improved comfort, while burning 25 percent less fuel than similar Chesapeake Class launches,” says Duclos.

Key design changes to the Chesapeake Class MKII include positioning the wheelhouse aft of amidships to improve comfort and provide for a larger foredeck.

With the pods close-coupled to the engines, the engine room is located well aft of the wheelhouse with easy access to machinery through a deck hatch.

This new generation of pilot boats is also designed to accept a gyro-stabilization system, designed to reduce vessel roll.

MIX OF REPAIR AT DETYENS
This past year, there has been a good mix of commercial and government repair at Detyens Shipyards, Inc., Charleston, SC, according to the company’s Bradley Kerr. “We have recently completed work on two German owned-container vessels, a pair of casino vessels and have the usual tugs and barge units, dredge vessel and other similar harbor barges are rolling through.  We also have recently won MSC contracts on the Button and Spearhead as well as the Atlantis from Woods Hole.”

The largest commercial ship repair yard on the U.S. East Coast, Detyens also recently finished repairs on the USCG Elm and will begin work on the NOAA vessel Gordon Gunter soon. The Dredge Wheeler is also in the shipyard.

This past spring and summer, Detyens dry docked the ferries 28,460 gt M/V Highlanders and 18,523 gt M/V Leif Ericson for Marine Atlantic, Inc., St John’s, Newfoundland, Canada.

FERRY REPOWER AT CADDELL
Over the next five years, the Delaware River and Bay Authority, owner and operator of the Cape May-Lewes Ferry, plans to repower its entire fleet with cleaner burning, more fuel efficient Tier 3-compliant diesel engines.

The first of those ferries, the Delaware, arrived at Caddell Dry Dock on Staten Island, NY, on November 2 to begin the four- to five-month repower project in conjunction with its regulatory required five-year drydocking.

According to James Gillespie, Chief Port Engineer for the Cape May Lewes ferry, the Delaware is expected to return to service in April of 2016. The dry-docking is expected to cost $3.5 million.

“We’re excited to begin our vessel repowering program,” says Heath Gehrke, Director of Operations for the Cape May-Lewes Ferry. “These new engines not only burn less fuel and are more efficient, but emissions are reduced by nearly 40 percent. By undertaking this effort, we can significantly extend the useful life of our fleet and provide a cleaner environment in the communities we serve.”

Gehrke also notes that the ferry expects to save about $130,000 per year in maintenance costs associated with old engines and that the new clean diesel engines have the capability to be converted to operate on natural gas in the future.

The existing Fairbanks Morse engines are overhauled and rebuilt every 10,000 hours of usage compared to every 30,000 hours for the new EMD (Electro-Motive Division) engines. The engines were purchased from Marine Systems Inc. at a cost of $1.8 million.

While at the shipyard, the vessel will have other modifications and improvements completed, including the installation of a new gray water recovery system, new stainless steel railings and new propeller shaft seal system; installation of a new keel cooler system for main engine and generator cooling; and the bow thruster system will be overhauled.

To further assist the University of Delaware’s water research efforts on the Delaware Bay, the SeaKeeper seawater monitoring system, which collects water quality data while a vessel transits the Delaware Bay, will be installed on the MV Delaware.

During a ceremony held at the Lewes Ferry terminal in December 2014, U.S. EPA Regional Administrator Shawn M. Garvin announced the award of a Diesel Emission Reduction Act (DERA) grant of $970,000 to help facilitate the project. The Delaware River and Bay Authority (DRBA) sought the grant funding through the National Clean Diesel Assistance Program, which focuses on reducing emissions at ports under the Diesel Emission Reduction Act (DERA).

The M/V Delaware is currently equipped with two Fairbanks Morse 38D8-1/8 propulsion engines with a power rating of 2,060 horsepower each. More than 40 years old, these workhorse engines are approaching 100,000 operating hours or the equivalent of 1.5 million miles. In addition, because the engines are no longer built, spare parts are both difficult to find and expensive.

Within the next five years, the Authority plans to repower the other vessels in the Cape May – Lewes Ferry fleet: the MV New Jersey and MV Cape Henlopen.

New Lake Constance ferry to have MTU gas engines

 

 

The intention is to have the new member of the fleet operated by the public utility running on gas between the two Lake Constance (the Bodensee) towns of Konstanz and Meersburg in 2019.

The new ferry will be one of the first in Europe to be powered by a high-speed pure-gas engine. It will feature low pollutant emissions and improved cost effectiveness, while delivering the accustomed high performance.

MTU is to develop the new 8-cylinder gas engine with a rated output of 750 kW based on the proven MTU Series 4000 diesel engines for workboats. The clean combustion concept will make it possible to meet IMO Tier III emission standards without the need for additional exhaust aftertreatment. By comparison with a diesel engine without exhaust aftertreatment, the gas engine will emit no soot particles and no sulfur oxides, 90 percent less NOx and 10 percent less greenhouse gas.

The new 8V 4000 gas engine will incorporate gas injection for individual cylinders, a dynamic engine control system and a safety concept optimized for natural gas operation.

The new gas engine series is being developed to ensure that it meets the particular load profile of the Lake Constance ferries, with acceleration comparable to that of the MTU diesel engines.In the development of the 8V 4000 engine, MTU benefits from its previous experience in stationary gas engines and from development work now being carried out for a 16-cylinder marine gas engine, which is currently underway and has just completed initial tests on the test bench. The first pre-series engines will power a tugboat in 2017, which is currently being built by Damen shipyards for Svitzer.

The MTU brand is part of Rolls-Royce Power Systems within the Land & Sea division of Rolls-Royce.

The Rolls-Royce Group, of which Rolls-Royce Power Systems is a member, has almost ten years’ experience in delivering medium-speed, pure-gas propulsion systems to power ferries.

“We are delighted that MTU, our partner of many years standing, is developing a natural gas propulsion system for our new ferry,” said Dr. Norbert Reuter, Managing Director of Stadtwerke Konstanz GmbH. “The deciding factors for us to venture into a new world of propulsion for our fleet are the excellent environmental compatibility of the gas engines and the possibility of saving fuel costs, while maintaining our current requirements in terms of the performance and maneuverability of the vessel. As a ferry operator on Lake Constance, Europe’s largest reservoir of drinking water, it is very important for us to guarantee safe and environmentally sound operations.”

“We are convinced that gas engines will become increasingly important as supplements to tried and tested diesel engines for shipping,” said Marcus A. Wassenberg, Chief Financial Officer at Rolls-Royce Power Systems AG. “Natural gas is an important fuel for the future. It will be available for a longer period of time and is cheaper in many regions throughout the world, in addition to having a far better carbon footprint than either heavy oil or diesel. With the development of the new gas engine and its trials in the ferry operated by Stadtwerke Konstanz, we are taking up the challenge of further improving the emissions and efficiency levels of gas engines, in order to be able to meet future emission regulations and the needs of our customers. The development of gas engine technology and the associated fuel infrastructure will also require state funding until they become economically viable.”

Chesapeake Shipbuilding to build three more tugs for Vane

They will be the 15th, 16th and 17th tugboats built for Vane Brothers by Chesapeake Shipbuilding since 2008.

Construction on the first new tug has already begun in one of Chesapeake Shipbuilding’s hull fabrication buildings.

The design of the new tugboats will be nearly identical to previous tugboats built for Vane Brothers. Each will be equipped with twin Caterpillar 3512 main engines, producing a combined 3,000 horsepower, and will have a single drum hydraulic winch from JonRie of New Jersey.

The tugs will measure 94′ long with a 32′ beam, and a 13′ depth.

All Chesapeake Shipbuilding tugs are built in a controlled indoor environment prior to being moved and launched into Maryland’s Wicomico River.

Chesapeake Shipbuilding has recently made significant upgrades to its shipyard to increase its production capacity and efficiency, including acquiring additional land, building two new hull fabrication buildings and investing in additional automated equipment.
The yard is located on 14 acres of level land, with more than 2,400 ft of deepwater bulkhead, along the protected waters of the Wicomico River. It has two large outfitting basins, three side launch systems, plus a ground transfer system and various hull fabrication buildings and shops.

Workboats and Patrol Boats: Small but Mighty

It’s no secret that the oil and gas sector is having a major impact on the industry with orders down at the larger shipyards and operators stacking their OSVs. Small boat builders, however, are thriving, remaining busy, and producing the hardest working vessels on the water, patrol boats and workboats.

Metal Shark, for example is in the midst of producing large work orders of patrol boats for a number of government agencies both in the U.S. and across the world. This year alone, Metal Shark, Jeanerette, LA, delivered multiple variants of its Endurance-class catamaran in the form of fireboats, multipurpose port security boats and Dive Support Vessels.

Back in March, the U.S. Navy awarded a $15,309,410 firm-fixed, indefinite-delivery/indefinite-quantity contract to Metal Shark to build 7-meter rigid hull inflatable boats (RHIBs) in support of Foreign Military Sales (FMS) requirements. Options could increase the contract value to over $47 million.

The RHIBs will support a variety of missions including personnel/cargo transfer, search and rescue, open water patrol, vessel interdiction and boarding, and the insertion/extraction of forces. Metal Shark says the boats will be produced in a flexible baseline configuration that can quickly be adapted via minor post-delivery alterations and delivered to support specific FMS case requirements worldwide.

At the time of the contract announcement, Chris Allard, President, Metal Shark said, “Large orders such as this one benefit Metal Shark customers large and small by way of increased production efficiencies and economies of scale that keep our pricing competitive, our workforce stable, and our technology on the leading edge.”

Currently, Metal Shark is producing boats for the U.S. Coast Guard’s RB-S and ATON-M program; and the U.S. Navy’s FPB-M and HSMST program.

This past August, the U.S. Coast Guard awarded Metal Shark with a $17.45 million delivery contract for 48 Response Boat-Small II vessels. The 29-ft high-speed RB-S IIs can reach a top speed of 40 knots, and are designed and engineered to handle a wide range of coast guard missions near the shoreline. Among them: search and rescue; law enforcement; ports; waterways and coastal security; drug and migrant interdiction; and environmental protection and response.

New yard helps meet demand
Metal Shark’s yard in Franklin, LA—acquired last year— enabled the company to expand the size of its vessel offerings, with the new yard supporting the construction of vessels up to 250 ft in length.

Metal Shark 75 Endurance PSLA FireboatRecently, Metal Shark’s Franklin yard delivered a 75 ft welded aluminum multipurpose port security vessel to the Port of South Louisiana. Based on Metal Shark’s Endurance-class catamaran design, the vessel features technology to support fire rescue missions, Command and Control (C2) operations, and around-the-clock port security efforts at the largest tonnage port in the western hemisphere.

The Port of South Louisiana stretches 54 miles along the Mississippi River, and handled over 291 million short tons of cargo in 2014 alone. According to the port, 4,000 oceangoing vessels and 55,000 barges call at the Port of South Louisiana each year.

“Our 75 Endurance is the most advanced fireboat design on the market, incorporating crew friendly features and advanced systems throughout,” says Allard. The vessel is powered by twin Cat C-18 diesel engines generating cruising speeds of 25 knots.

To meet firefighting needs, the 75 Endurance can channel 6,000 total gallons per minute through an oversized water main where electronic valves divert water to three radio frequency-controlled monitors. Additionally, the vessel includes four hydrant connections and a 400-gallon foam reservoir.

Its state-of-the-art Command and Control suite enables multi-agency coordination during emergency response events, and a positive pressure Chemical, Biological, Radiological, Nuclear, and high-yield Explosive (CBRNE) ventilation system that can provide crew protection during disaster responses.

Metal Shark has also delivered a number of FMS boats to government agencies worldwide, including 32 Defiant patrol boats to Uruguay, 38 Defiant patrol boats to Bangladesh, and 38 Defiant patrol boats to Senegal.

The boat builder’s Defiant class is among its most popular models, and at this month’s International Workboat Show, Metal Shark will showcase its new 45 ft Defiant variant, which fills the gap between Metal Shark’s 38 ft and 55 ft Defiant class offerings. Metal Shark is currently producing multiple 45 Defiant vessels for Vietnam. The vessels are part of a larger FMS contract for Vietnam.

Earlier this year, U.S. Secretary of Defense Ash Carter announced that the U.S. would provide $18 million to Vietnam to help the country acquire patrol boats specifically built by Metal Shark. At a press conference held during his trip to Vietnam, Carter said both countries are “committed to deepening our defense relationship, and laying the groundwork for the next 20 years of our partnership.” He further added that by working together, the two countries will “continue to strengthen the region’s security architecture so all our countries and others all around the region can continue to rise and prosper.”

To say that Metal Shark is a little busy would be a gross understatement. The secret to its success is its willingness to be flexible and attentive with its customers. “Being able to simultaneously accommodate multiple markets is a significant factor in our success,” explains Allard. “There are some yards that focus on fireboats, others on pilot boats, or patrol boats. We’re active— and enjoying success—in all of those markets. More important than our product range, however, is having the ability to anticipate our customers’ needs by closely observing market trends, by maintaining relationships with existing customers, and by responding to their feedback. When a new client walks through the door we greet them with ready-made solutions, and we’re willing to work with them to modify our offerings if their needs require it.  Our designs are constantly evolving, so having a large in–house design team is crucial, because it allows us to move far more quickly than yards relying solely on outside firms.”

Marine Group Boat Works stays busy
For California’s Marine Group Boat Works, the key to flourishing during a rough market environment is the willingness to diversify its business. “Our vision was to bring custom boatbuilding back to California,” says Todd Roberts, President, Marine Group Boat Works. Roberts says the company’s extensive history with boats has given it a “360-degree perspective” on how it approaches a project, and because it offers both newbuild and repair services, it is with the customer from “cradle to grave.”

The family-owned shipbuilding and repair company has three yards, two in Chula Vista and National City, San Diego, CA, and one in San Jose del Cabo, Mexico.

Marine Group’s yard “is running at 95 to 100 percent capacity,” according to Roberts, with a full order log for its workboats and dive boats in the works, and delivery expected over the next five years.

That full order book is the result of a major U.S. Navy contract the yard won earlier this year for the construction of 27 new vessels worth over $45 million. The contracts were for five steel tugboats; six large steel workboats; 16 aluminum 60 ft diveboats. “Multi-year, multi-vessel contracts are what our economy needs,” says Roberts.

According to Roberts, the first two of the smaller workboats for the Navy are near completion and will be delivered early 2016.

Kvichak constructing fourth RB-M C for NYPD
In spring 2016, the New York City Police Department Harbor Unit will take delivery of the fourth in a series of 44.5 ft Response Boat Medium-C patrol vessels being built for the agency by Seattle-based Kvichak Marine Industries. Kvichak, now a Vigor Company following the two companies merger earlier this year, delivered the first three RB-M Cs in April 2010, August 2012 and April 2013, respectively.

Originally, the Response Boat Medium class was designed by Camarc Design, UK for the U.S. Coast Guard’s new RB-M fleet. The RB-M class—which replaced the Coast Guard’s 41ft utility boats—featured a total of 174 boats built and delivered by the RB-M team, comprised of Kvichak and Wisconsin-based shipbuilder Marinette Marine. The final vessel in the 174-RB-M series, the RB-M 45774, was delivered to the U.S. Coast Guard this past March.

Designed with speed in mind, the RB-M features an all aluminum construction; a deep V hull for balance and stability— helping improve and increase response time; and can travel at a speed up to 42.5 knots, and operate a 250 nautical mile range at 30 knots.

The commercial spin off of the class, the RB-M C features the same high-speed flexibility and agility, but with additional customizable features. For example, the NYPD RB-M C features a heated deck, and the RB-M C delivered to Los Angeles County in 2013 has a roof mounted RS-700 Gamma/Neutron Radiation Detection System.

The NYPD RB-M C will be powered by Tier 2-compliant Detroit Diesel 60 series engines. Its propulsion will be supplied by Rolls Royce Kamewa FF375S waterjets. The vessel will also come equipped with a Furuno Navnet system, SeaFLIR Voyager III system and Kohler 9kW genset for AC power. Its climate controlled pilot-house, cabin and heated windows offer the crew protection from the elements.

Kvichak’s ability to produce high quality aluminum patrol and workboat vessels was one of the reasons Vigor hoped to merge with the small boat builder. At the time of the merger, Vigor CEO and owner Frank Foti said, “The Kvichak team builds the best aluminum workboats in the country, arguably the world. Infusing those fabrication genetics into our broader operations is what industrial evolution is all about.”

Silver Ships delivers rescue boat to Southampton
East of New York City, the coastal town of Southampton, Long Island, will be safer thanks to the newest member in the NY/Southampton Bay Constables fleet. Alabama-based Silver Ships, Inc., recently delivered the 21-foot center console all-aluminum patrol/rescue boat to the operator. The Freedom 21 vessel will be used for patrol, rescue, homeland security, and law enforcement purposes around the town of Southampton—the town is surrounded by a number of inland waterways, as well as Shinnecock Bay, and the Atlantic Ocean.

“The Freedom 21 Law Enforcement Vessel is sure to be a tremendous long-term asset for the Southampton Bay Constables and will be available [for] year round operation,” said Silver Ships’ Malcolm Wisch. Designed by naval architect Lou Codega, PE, Smithfield, VA, the vessel features an all-aluminum hull and superstructure making it both durable and rugged. Freedom 21 was engineered specifically for one-man operation. It features an upholstered leaning post with gun and storage lockers, as well as an ergonomically-designed helm area with seat bench/storage box on the forward side of the console.

Silver Ships will follow up the delivery of Freedom 21 with another vessel for Southampton Bay Constables, Freedom 25, which is currently under construction. Freedom 25 will feature a full pilothouse that is climate controlled, and will have CBRNE capabilities.

Gladding-Hearn delivers new generation of boats
Colombia is making a come back. Tourism is on the rise for the South American country as its violent history fades and the country’s lands and vibrant culture take center stage. One way Colombia is making its lands safer is by putting patrol boats in its waters—the country borders the Pacific Ocean to the west and the Caribbean Sea to the northeast. To help meet that goal, in 2014 the Colombian Department of the Navy called upon Massachusetts-based Gladding-Hearn Shipbuilding, Duclos Corporation, to build and deliver six Chesapeake Class pilot boats.The final vessel in the series was delivered to the Colombian Navy earlier this year.

Designed by C. Raymond Hunt & Associates, the 56 ft boats, which are being used for coastal and offshore patrol operations and port security, feature an all-aluminum deep-V hull and are powered by twin MAN R6-800CRM diesel engines each delivering 800 Bhp at 2,300 rev/min, and capable of reaching a top speed of 27 knots.

C. Raymond Hunt & Associates also provided the design for a new generation of pilot boats recently delivered by Gladding-Hearn to the Tampa Bay Pilot Association—the Chesapeake Class MKII. The vessels, a spinoff of the Chesapeake Class, feature improved performance thanks in part to the addition of Volvo Penta’s IPS 2 pod system.

“This new generation of Chesapeake launches, named Chesapeake Class MKII, is equipped with the IPS 2 pods, which provide what pilots have been asking for: higher speeds, lower fuel consumption, and more comfort,” says Peter Duclos, President of Gladding-Hearn.

The new generation boats are powered by twin Volvo Penta D11, six-cylinder, EPA Tier 3 diesel engines, each producing 503 Bhp at 2,250 rev/min. Volva Penta’s integrated EPS electronic steering and control system, along with the three-axis joystick increases the pilot boat’s overall maneuverability when docking alongside another vessel.

The inclusion of a Humphree Interceptor automatic trim-optimization system gives the pilots higher speeds and improved comfort, while burning 25 percent less fuel than similar Chesapeake Class launches, says Duclos.

Gladding 70ft NYPDpatrolboat3Prior to its delivery of the Tampa Bay Pilot boats, Gladding-Hearn delivered the second in a series of 70 ft Tactical Response Vessels to New York City’s Harbor Patrol Unit. The vessels, says the yard, are designed and built to respond to terrorist activities on New York City’s waterways. The all-aluminum vessel’s superstructure includes a 360 degree wheelhouse, further enhanced by the fly-bridge which has ballistic-resistant windows and panels. The vessels also feature two decontamination showers; an American Safe Room Nuclear, Biological and Chemical (NBC) filtration system to help pressurize the vessel’s accommodation spaces; and a 1,500 gallons/min remote control water cannon mounted on the pilot house roof.

Powered by twin 12-cylinder MTU-12V2000M94 diesel engines, the vessel can reach a top speed of over 41 knots, and at 30 knots a range of about 225 miles. The MTU engines turn a pair of Hamilton HM571 waterjets through ZF3050 gearboxes. Meanwhile, a 30 kW Northern Lights/Alaska Diesel generator provides service power.

Additionally, Gladding-Hearn completed the delivery of a five-boat contract for the NYPD. The 61 ft high-speed dive boats were specifically engineered for the NYPD’s harbor unit dive team.

Willard unveils new Sea Force
California-based Willard Marine, Inc. has debuted its new Sea Force 777. The 7.7 m long military-grade, fiberglass, rigid hull inflatable boat (RHIB) can be used for a number of blue water missions including rescue, patrol and visit/board/search and seizure.

WILLARD SEAFORCE777The RHIB is designed with a deep-V hull to maximize stability. Sea Force 777 will feature a UV-coated, 40-ounce polyurethane WING inflatable collar, with a 7-panel bow cover and rub-strakes to reduce damage during boarding and weight shifting.

The Sea Force 777 is a larger version of Willard’s military-grade RHIBs. The vessel is customizable, and can be made in aluminum; additionally, Willard says it can accommodate a variety of seating configurations, law enforcement equipment, electrical packages, weather protection, and navigation devices.

On the heels of the new Sea Force debut, Willard Marine won a contract from the National Oceanic Atmospheric Administration (NOAA) to build a modified version of its Sea Force 730 RHIB. The 20 ft RHIB will be operated by the Pacific Island Fisheries Science Center.

The vessel will perform fisheries and marine mammal research, including collecting samples, remote sensing survey, and marine mammal population surveys throughout the Pacific region. Vessel delivery is scheduled for Summer 2016.

Willard Marine was also tapped to construct three 28-ft aluminum Hydrographic Survey Launch Ships (HSLs) for NOAA. The HSLs are based on former SeaArk Marine’s commercial boat design—Willard Marine is the exclusive builder of SeaArk Marine designed commercial vessels—and the HSLs will add flexibility and autonomous capability to NOAA’s fleet.

The HSLs will be used on waters off the U.S. coast to conduct oceanographic surveys with hull-mounted and towed sonar units. Power will be provided by a Cummins QSC8.3 engine capable of generating 510 hp with a ZF Marine 305-2 transmission.

Two of the vessels will be built for NOAA’s 208 ft Thomas Jefferson; and the other boat will be built for the 231 ft NOAA ship Rainier. The two ships are used to conduct hydrographic surveys to update NOAA’s suite of nautical charts.

The HSLs will be delivered to NOAA during the Fall of 2016.

Moose Boats delivers M2-32 Cat
Moose Boats’ M2-35 catamaran design is often a popular choice for agencies looking to add speed to their fleet. One such operator is the Placer County Sheriff’s office, Lake Tahoe, CA, which will soon take delivery of an M2-35 patrol catamaran. The M2-35 vessels are powered by twin Yamaha F350 outboards enabling the vessel to reach speeds up to 45 knots.

Earlier this year, Moose Boats completed and delivered two M2-35 outboard catamarans to the Port Authority of NY/NJ. Those two vessels would be used in patrol and rescue missions.

Beyond the M2-35, Moose Boats is expanding its monohull line up, making further developments to its M3-30. According to Moose Boats General Manager Stephen Dirkes, the design features a slightly narrower cabin that allows crew to walk around the cabin for easy access to the bow. The hull’s length was also reduced to under 30 ft, making it a perfect fit for one-man operation. The M3-30 has undergone rigorous testing by law enforcements in both coasts, where it topped speeds of over 45 knots.

Brunswick delivers workhorse to Wildlife Commission
Florida Fish and Wildlife Commission recently took delivery of the first-of-its-kind 30 ft Sentry aluminum boat from Brunswick Commercial and Government Products (BCGP).

The new Sentry model is part of BCGP’s aluminum boat line up and complements the already existing Sentry line up which includes 32 ft, 36 ft, 40 ft and 45 ft variants.

The line up is the result of a Master Supply Agreement between BCGP and Canada-based MetalCraft Marine.

“This new [Sentry] platform was designed to accommodate many features needed in the maritime security industry,” said BCGP’s Jeremy Davis. “Whether the mission is port security, game conservation or the safety of recreational boaters, this vessel can easily be customized to fit the needs of law enforcement agencies around the world.”

The Sentry class is designed with port security and patrol missions in mind. It features a forward cuddy cabin, computer workstation and lockable weapon storage.

North River Boats produces Valor for Fire and Rescue missions
Up in Roseburg, OR, North River Boats recently delivered a new 38 ft fireboat to North Kitsap Fire and Rescue. Based on North River’s Valor design, the vessel is capable of generating top speeds of up to 35 knots and maintains a cruising speed of 25 knots.

The vessel, says North River, comes fitted with a Kem Equipment, Kodiak 6.0L fire engine, coupled to a Hale 60FBM Fire Pump System that delivers up to 2000 GPM from the two monitors.

On the vessel’s bow is a Task Force Tips (TFT) remote operated monitor that provides crew with firefighting suppression—the adjustable nozzle enables the operator to quickly go from fan to full stream.

Additionally, Simrad displays and the Simrad digital radar, GPS, Wireless Intercom/Headset System; an Icom M604 VHF radio and a FLIR M 625L thermal imaging camera are featured on the vessel.

Robert Allan designs new RAmparts tug for Chile’s SAAM

 

The first two boats, named Chincha and Tupac, are now under construction at the Wuxi Shipyard in China, for SAAM’s Peruvian affiliate Tramarsa, with others soon to follow.

In addition to the design, Robert Allan Ltd. also provided a complete structural steel parts package developed from the design drawings prepared for this project. Parts were defined and nested using ShipConstructor software, complete with part identification code, suitable as input to the shipbuilder’s NC burning code.

The hull form and layout have evolved through the extensive experience of the designers. Ship-handling is performed over the bow using a high-performance, split drum hawser winch.

The tugs will also provide firefighting capability and have up to date accommodations for a crew of six in two single and two double cabins.

The design complies with ABS requirements for the following notations: ✠A1, , ✠ AMS, Towing Vessel, UWILD, Fire-fighting Vessel Class 1 Particulars of the RAmparts 2400-W design are as follows: Length overall

Vane Brothers takes delivery of latest Maryland-built tug

The Fort Schuyler is the eleventh Sassafras Class tugboat built for Vane Brothers by Chesapeake Shipbuilding, Salisbury, MD. Its sister tug, the Kings Point, was delivered in April this year.

“Working alongside another Maryland-­‐based company to deliver safer and more productive working vessels such as the Fort Schuyler has been a great experience for Vane,” says Vane Brothers President C. Duff Hughes. “Chesapeake Shipbuilding is helping us to further our mission of providing the highest quality service to our customers.”

Measuring 94 feet long and 32 feet wide with a hull depth of 13 feet, the Fort Schuyler is similar in most respects to the previous ten tugs built for Vane by the shipyard.

The vessel is equipped with twin Caterpillar 3512 Tier 3 main engines producing a combined 3,000 horsepower, and operates with a single-drum hydraulic towing winch.

“Soft-core” panels and heavy, fire-rated doors are used throughout, offering the crew a safer and quieter living environment.

In a first for Vane Brothers, the Fort Schuyler’s state-­‐of-­‐the-­‐art wheelhouse features multi-­‐functional Simrad marine electronics that utilize intuitive interfaces for heightened performance.

The Fort Schuyler, like the Kings Point, has joined Vane Brothers’ fleet based in New York.The two vessels are named for the campuses of SUNY Maritime College in Fort Schuyler, NY, and the U.S. Merchant Marine Academy in Kings Point,NY.

 

VT Halter launches 130 ft ATB tug for Bouchard

 

The vessel is one of two sister vessels being built under a two vessel contract signed with Bouchard Transportation, Inc. in August 2014. Morton S. Bouchard and sister vessel Frederick E. Bouchard each measure 130 feet by 38 feet by 22 feet and is classed by ABS as +A1 Ocean Towing , Dual Mode ATB, USCG Subchapter C. On completion, both tugs will be equipped with an Intercon Coupler System. Deliveries are expected in January and May 2016 respectively. The vessels will enter into Bouchard Transportation’s fleet service in New York, N.Y.

This most recent launch follows the September launch from the Moss Point shipyard of another ATB tug for Bouchard, the 10,000 hp M/V Donna J. Bouchard.

Also equipped with an Intercon Coupler, Donna J. Bouchard, is classed by ABS as +A1 Towing Vessel, Dual Mode ATB, USCG Subchapter M.
She will be paired with barge B.No.272, which is currently under construction at VT Halter Marine’s Pascagoula, MS, shipyard to comprise the second ATB unit built for Bouchard Transportation as part of its major expansion program.

“Bouchard Transportation Co. Inc. is happy to announce yet another successful launching of a state of the art ATB tug built by VT Halter Marine. The launching of the M/V Morton S. Bouchard Jr. is a special event within the Bouchard Family, for the vessel is named after the father of President/CEO, Morton S. Bouchard III, who wanted his father’s name to always remain on the waterfront for which he dedicated his entire fife to. The original tug, Morton S Bouchard Jr., which was also built by Halter, was earlier renamed as The Bouchard Boys and continues to operate with Bouchard Fleet,” said Morton S. Bouchard III President and CEO, Bouchard Transportation.

“The successful launching of both vessels, the M/V Morton S. Bouchard Jr. today and the M/V Donna J. Bouchard in September is an indication of the commitment to the continued relationship with Bouchard Transportation. We are pleased and proud to celebrate this important milestone in the life of any vessel, and we look forward to having these superb tugboats join the Bouchard Transportation fleet,” said Jack Prendergast, CEO, VT Halter Marine
