Anyone needing reassurance that the shipbuilding sector in the United States is alive and well need look no further than the Great Lakes. While yards along the U.S. Gulf reshuffle business strategies to help during the down oil market, yards along the Great Lakes continue to work on a number of projects, investing in infrastructure and leveraging partnerships to diversify portfolio offerings.
Perhaps the busiest group of all is Fincantieri Marine Group (FMG)—the U.S. subsidiary of one of the world’s largest shipbuilders in the world, Fincantieri. The Fincantieri Marine Group is comprised of three Great Lakes shipyards—Fincantieri Bay Shipbuilding (FBS), Fincantieri Marinette Marine (FMM), and Fincantieri ACE Marine (FAM).
Since acquiring the Wisconsin yards in 2008, Fincantieri has invested well over $100 million to build a shipbuilding group that will provide flexibility for its customers, and provide construction and repair services to both the government and commercial sectors.
Sturgeon Bay, WI-based Fincantieri Bay Shipbuilding (FBS), which is one of the last boat builders remaining in the Bay, has been essentially non-stop the last couple of years. The yard currently has numerous projects under various stages of construction with a backlog that extends through 2018. Most notably, the projects include newbuilds for one of the most active sectors in the country, the ATB market.
This past May, the yard delivered the Articulated Tug Barge (ATB) unit Barbara Carol Ann Moran and the 110,000 barrel ocean tank barge Louisiana to Moran Towing Corporation, New Canaan, CT. The unit was the third delivery to Moran under a 2014 contract.
The 5,300 HP, 121 ft ATB tug Barbara Carol Ann Moran is certified ABS Class +A-1 Towing Service, +AMS, and is equipped with state-of-the-art navigation and communications technology.
What made the delivery of the unit so impressive was that it was delivered on the exact day called for by the contract—emphasizing FBS’ high standards of meeting customer requirements, building a quality vessel and delivering on time.
Currently, FBS is under contract to construct two ATB tugs and two ocean going tank barges for Kirby Corporation; one ATB tug and one oceangoing tank barge for Plains All American Pipeline, LP; and one ATB tug and one oceangoing tank barge for AMA Capital Partners.
“We continue to be optimistic about the future of the industry we serve,” says, Todd Thayse, Fincantieri Bay Shipyard Vice President and General Manager.
To keep the momentum going, Fincantieri recently purchased the Palmer Johnson facility adjacent to the Bay Shipbuilding yard. Bay Shipbuilding has extensive expansion plans set for the 3-acre site, including the construction of new indoor Fabrication/Erection facilities, an indoor Blast and Coating building, outfitting shops and additional office facilities.
“This recent acquisition of the former Palmer Johnson facility has been well received by the industry and will allow us to pursue several new construction projects, which may include fishing vessels, ferries and landing crafts, while continuing to serve our core ATB market. These purpose-designed buildings will increase our overall output and capacity and improve our ability to meet critical schedules,” says Thayse.
“We will also be able to move more construction indoors which will allow FBS to further provide cost-effective solutions for our customers,” he added.
Indoor facilities will enable work to be ongoing for both newbuilds and repair work—especially during the winter months when Great Lakes fleet repairs are vital and time sensitive.
Earlier this year, FBS had 17 vessels at the yard undergoing winter repairs well into April. The vessels ranged from thousand-foot long bulk tankers, to medium-sized ships, to tugs and barges. Work included large-scale scheduled maintenance repairs, scrubber installations, repowering and structural steel renewal, in addition to electrical automation enhancement and ABS and U.S. Coast Guard inspections.
Additionally, Keylakes Shipping’s 768 ft bulk carrier John G. Munson is currently undergoing conversion at Bay Shipbuilding. The vessel is the tenth steam-to-diesel, or diesel-to-diesel repowering project that FBS has been awarded since 2009. The freighter, built in 1952 will undergo a complete repower at FBS. It is expected to undergo sea trials in 2018.
Meanwhile, FMG’s two other Great Lakes shipyards are busy constructing the next generation of warships for the U.S. Navy.
Earlier this summer, a keel laying ceremony was held at Fincantieri Marinette Marine, Marinette, WI, for the U.S. Navy’s 17th Littoral Combat Ship (LCS), the USS Indianapolis. The ship is one of six in various stages of construction at FMM, with an additional three ships in long-lead procurement. The yard has already delivered four LCS ships to the Navy—the USS Freedom (the lead ship in the Freedom variant), the USS Fort Worth, the USS Milwaukee and the USS Detroit.
The Lockheed Martin-led team is made up of Fincantieri Marinette Marine, along with naval architectural firm Gibbs & Cox, and more than 500 suppliers across 37 states. The U.S. Navy’s LCS construction program is divided between two groups—the Lockheed Martin team, building the Freedom variant, and the General Dynamics-led team, with Alabama-based Austal USA building the Independence class LCS.
Fincantieri Ace Marine, Green Bay, WI, also has a hand in producing the Freedom variant of the LCS. The yard, which specializes in the design and construction of high-speed coastal intercept and patrol vessels, most notably the builder of the Response Boat-Medium (RB-M) for the U.S. Coast Guard, produces the aluminum superstructures and additional aluminum components for the class.
To top off FMG’s three shipyards success, all three received the annual “Excellence in Safety” award from the Shipbuilders Council of America earlier this year. The award recognizes a shipyard’s commitment to safety, and the hard work and dedication put forth from shipyard employees.
The Great Lakes Group Eyes Expansion, Partners with Damen
FMG isn’t the only regional player seeking to further develop. This past June, the City of Cleveland authorized the sale of property adjacent to the Great Lakes Towing company headquarters. The acquisition of the property will enable the Great Lakes Shipyard, part of The Great Lakes Group, to operate at full capacity, all year round.
The expansion will include a 68,000 square foot facility that will accommodate a state-of-the-art 770-ton mobile Marine Travelift crane—the largest on the Great Lakes, and third largest in the world.
Great Lakes Group says that with the new facility in place, the Great Lakes Shipyard will be able to continuously provide all services for new vessel construction, as well as custom fabrication, ship maintenance and repairs.
Part of the services Great Lakes Shipyard will offer are those required for Subchapter M. Under Subchapter M regulations, towing vessels greater than 26 ft, or any vessel type moving dangerous or hazardous materials, must obtain a Certificate of Inspection documenting: Drydock inspection; Internal Structure Exam; Annual Inspection and Surveys; and Machinery and Electrical.
Just last month, the yard kicked off construction for the first Damen Stan Tug 1907 ICE. The tug is the first in a series of ten being built in compliance with the new Subchapter M regulations. The tugs are being built for The Great Lakes Towing Company (the Towing Company).
The tugs will measure 65 ft x 24 ft x 9 ft and will be powered by two MTU 8V4000 M54R engines generating 1,000 hp at 1,600 rev/min.
“This new construction program is further evidence of the innovative spirit the Towing Company has always embraced since its founding over 117 years ago, and reflects the commitment we have to our customers and the entire Great Lakes/St. Lawrence Seaway marine transportation industry,” says Joe Starck, President of the Towing Company.
Under the construction program two new harbor tugs will be introduced each year for the next five years—helping to stabilize operations and improve day-to-day business, assures Starck.
“The tugs,” he added, “will be ideal for the long-term sustainability of our harbor towing activities, and provide our customers with an even greater level of reliability, performance, and safety, across our entire Great Lakes service network.”
The Great Lakes Towing Company’s fleet provides ship assist, cargo transportation and logistics, ice breaking, and emergency assistance for every kind of vessel, barge and marine structure on the Great Lakes-St. Lawrence Seaway.
The Damen Stan Tug 1907 ICE are also the first tugs to be built in the U.S. under Damen’s Technical Cooperation program with Great Lakes Shipyard. The agreement, which was entered into at last year’s Workboat show, authorizes the Great Lakes Shipyard as an official builder of Damen designs for the next five years.
Burger Boat’s diverse portfolio
Since 1863 Burger Boat Company, Manitowoc, WI, has done everything in its power to meet the needs of its growing customer base. The boat builder, which has delivered countless vessel types in the range of 50 ft to 200 ft in length, implements what it calls a “lean” philosophy to its business practice, ensuring procedures are performed and completed on time, and vessels are delivered to customers on budget.
A builder of steel and aluminum vessels, Burger builds everything from yachts to passenger vessels, such as the 98 ft passenger vessel Chicago’s Classic Lady for Chicago’s First Lady Cruises—and patrol to research vessels, such as the 78 ft research vessel Arcticus which was delivered to the U.S. Geological Survey in 2014, just to name is a few.
Last year, Burger delivered a tour boat to Chicago-based Wendella Boats. The 340- passenger Lucia is an 89 ft steel vessel that was designed by Timothy Graul Marine Design, Sturgeon Bay, WI. The steel boat is certified USCG Subchapter K, and is powered by two Caterpillar C12 main engines and features two Northern Lights generators.
Most recently, Burger began construction on a custom 103 ft 6 in x 26 ft 5 in full displacement steel and aluminum Explorer Motor Yacht for an unnamed owner.
The expedition style motor yacht has a steel hull and aluminum superstructure. The vessel, designed by DeBasto Design, Miami, FL, will be launched Spring 2017. The ABS class yacht will be powered by two Cat C-18 ACERT main engines, and will be able to reach a cruising speed of 12 knots.
Fraser faces OSHA fine
Located in Superior Wisconsin, on the St. Louis Bay of Lake Superior, Fraser Shipyards, part of the Fraser Industries group which also includes boat builders Lake Assault Boats, provides full shipyard services from its sixty five acre site, featuring two dry docks and approximately 2,200 feet of berthing space. Since 1890, Fraser Shipyards has been a prominent fixture in the Twin Ports of Duluth and Superior, serving the Great Lakes shipping community. Most of its current 150 workers, 75 percent of which are structural welders, equipment operators, fitters and pipe fitters, are third generation employees for the company.
That kind of longevity and loyalty from workers can serve as a testament to Fraser’s commitment to the industry, the community and its employees, but recent findings have raised questions about the yard’s safety culture.
Last month, the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) announced that sampling results taken during a recent retrofit determined that 14 of Fraser Shipyards workers were exposed to heavy metals and had lead levels 20 times higher than the exposure limit.
According to OSHA’s Assistant Secretary of Labor, Dr. David Michaels, “Fraser Shipyards accepted a contract with a very low profit margin and penalties for delayed completion, but could not meet the schedule without endangering its workers.”
That contract, from Interlake Steamship Company, Middleburg Heights, OH, was for the modernization of the Herbert C. Jackson. OSHA stated in its report that Fraser Shipyards’ management was aware of the presence of lead and asbestos throughout the 1959 built vessel. The ship arrived at Fraser December 2015 for a six-month retrofit project and was required back in operation for the summer iron ore shipping season.
In a statement, James Farkas, President and Chief Operating Officer of Fraser Industries, said “We are a family-owned company that has been in Superior for 126 years. We see all of our employees, laborers and contractors as part of the family.”
He added, “We take the health and safety of our people and our community seriously. We acted to protect our people as soon as we learned of the problem. We have worked with all of our employees, laborers and contractors to ensure their health by bringing in medical experts, as well as the highest levels of testing, protective equipment and safe operating procedures. We strongly disagree with OSHA’s statement that any of the issues were caused or worsened by business or profit motivations.”
The agency cited 14 willful egregious health violations for each instance of overexposing a worker to lead, and cited five additional willful violations for failing to conduct monitoring to assess lead exposure and failing to implement a lead compliance or respiratory program.
Additionally, OSHA issued 10 serious violations to the company, and placed Fraser Shipyards in its Severe Violator Enforcement Program (SVEP). For companies on the list, mandatory follow-up inspections become the norm.
Since the findings, Fraser has taken steps to help mediate the matter, and protect its employees. According to a statement, as soon as the management learned of the high lead levels it halted work on the Herbert C. Jackson. Fraser Shipyards also went on to engage medical experts from the region’s two leading hospitals, and industrial safety experts from the International Brotherhood of Boilermakers union to advise the company and oversee health testing. And it purchased state-of-the-art safety gear and equipment to protect workers.
Additionally, Fraser engaged medical professionals, OSHA and union officials to develop and implement new safety procedures.
“We appreciate their responsiveness to getting this issue fixed and taking care our members,” said Mark Garrett, Director of Health and Safety Services for the International Brotherhood of Boilermakers, the union that represents workers at the yard. “We don’t get many employers that step up like they did. They were straightforward, asked for our help and put in place our recommendations for safety.”
In total, Fraser could face close to $1.4m in OSHA penalties.
SEPTEMBER 6, 2016 — ABB says that the latest version of its podded electric propulsion system, the Azipod XL, increases vessel fuel efficiency by as much as 20 percent compared to modern
SEPTEMBER 1, 2016 — Eastern Shipbuilding Group, Inc. Panama City, FL, reports that it has delivered the M/V Harvey Stone (Hull 234) to Harvey Gulf International Marine, LLC of New Orleans, LA.
Vessel operators are still very much focused on reducing fuel consumption and lowering emissions. Collaboration early on in the design of a new vessel and its construction between the vessel owner, naval architects, shipbuilders, and propulsion manufacturers can payoff in optimizing the vessel’s hull, reducing costs of construction, and lowering operational costs during a vessel’s lifetime.
“We work with naval architects early in the design process to help optimize the propulsion system, looking to meet all design requirements while minimizing the size and horsepower of the system,” says Elizabeth Boyd, PE, President, Nautican Research & Development Ltd. Boyd says collaboration early in the design phase “can result in significant savings because if the horsepower can be reduced due to efficiency gains, it can lead to size reductions in not just the horsepower and propellers, but also everything that goes along with it—shafts, bearings, etc.—sometimes it can even mean meeting the requirements with a smaller boat. We can quickly show performance and full system configuration for different sizes, allowing the naval architect to explore options very quickly.”
Nautican’s foundation was built on efficiency. More than 40 years ago, company founder Josip Gruzling pioneered the use of hydrofoils to increase the efficiency of tugs and barges. Today, Nautican engineers and manufactures hydrodynamic solutions, including patented Integrated Propulsion Units, High efficiency nozzles and propellers, high aspect ratio triple rudders, pre-swirl stators, and also hydralift skegs for barges. It says independent tests show that its propulsion system solutions increase power and maneuverability, while significantly reducing fuel use and maintenance needs.
One of the Nautican’s latest projects is fabricating the first two sets of 104-inch nozzle units for the 120 ft Kirby Offshore Marine line haul tugs under construction at Nichols Brothers Boat Builders, Whidbey Island, WA.
According to Boyd, initially nozzle development was done using both Computational Fluid Dynamics (CFD) and physical testing in a cavitation tunnel and towing tank. “However,” she says, “our CFD efforts now are focused more on integration with the hull form. For these boats, CFD was not used as the design was already well developed and fairly straight-forward as far as placing the nozzles.”
The designer of the ABS Class tugs is Jensen Maritime, Crowley Maritime Corp.’s Seattle-based naval architecture and marine engineering company.
Each of the two tugboats will be equipped with two Caterpillar 3516C main engines, rated at 2,447 hp at 1,600 rev/min. Reintjes reduction gears, supplied by Karl Senner, LLC, Kenner, LA, will turn two Nautican fixed-pitch propellers with fixed nozzles. Other equipment onboard the tugs will include two C7.1 Caterpillar generators for electrical service, one TESD-34 Markey tow winch, one CEW-60 Markey electric capstan and one Smith Berger Town Pin.
“Kirby owns many boats with Nautican systems, but most of these have been ATBs (Articulated Tug Barge units) to date,” says Boyd. “We worked recently with Nichols on a pair of Kirby 10,000 hp ATB tugs—this project went very well and these vessels are performing exceptionally well in service.”
Nautican designed larger 120 inch nozzle units for another tug for Dunlap Towing. “Dunlap is a Nautican repeat customer,” says Boyd. The new tug, says Boyd is a new design, based on the Phyllis Dunlap, but “fully rethought and redesigned by Hockema Whalen.”
The 5,000 hp, twin-screw tug Phyllis Dunlap was built in 2001 by Hansen Boat Company, Everett, WA.
“Dunlap has been a great customer to work with—they are very involved in all aspects of the design and equipment selection and are very knowledgeable, providing some really useful feedback about performance over the years in their very demanding runs to Hawaii and Alaska.”
Wärtsilä Transverse Thruster
Earlier this year, Wärtsilä expanded its transverse thruster series with the addition of the Wärtsilä WTT-40, with a 4,000 kW power level and a 3,400 mm diameter controllable pitch propeller. While Wärtsilä has designed and built customized transverse thrusters as powerful as 5,500 kW, the WTT-40 and others in the WTT range address customer needs for high power transverse thrusters for bow and stern applications.
Development work on the Wärtsilä WTT-40 began in 2015 with an eye on targeting cruise ships, large OSVs and offshore construction vessels. The high power level is particularly important for the harbor maneuvering and docking of large ships, and for dynamic positioning of offshore vessels working in heavy sea conditions.
Because of its maximum power of 4,000 kW, shipyards and cruise vessel designers have the option of using three WTT-40 thrusters instead of four smaller ones. This translates into a more efficient vessel design with less space required for the transverse thrusters. It also allows thrusters to be installed closer to the bow where they are more effective.
Wärtsilä’s extensive experience with propeller design and tunnel optimizations using CFD analysis, ensures an optimal solution when it comes to propulsion performance, efficiency, and the minimization of noise and vibration.
Another benefit of the Wärtsilä WTT-40 is its integrated hydraulics, which save machinery room space and installation and commissioning time at the shipyard.
Innovative ship propulsion systems made by RENK
Military vessels such as patrol boats, corvettes, and frigates looking for “silent running” might well be interested in the Renk Advanced Electric Drive AED. The new drive from the Augsburg, Germany, plant offers a number of special advantages for shipbuilders, says Renk. The propulsion system is a real alternative to the heavy, space consuming electric motors that are rotating at propeller speed.
Modern power electronics allow the use of high-speed motors in combination with an efficient gearbox. The Renk AED combines electric motor and gearbox on one joint frame. Built on soft elastic mounts and equipped with a highly elastic propulsion coupling an incomparably silent operation is possible. The water-jacket of the water-cooled electric motor as well as the double helical reduction gear add to extremely low noise operation.
A modularized lightweight
Thanks to the compact design as well as the low height the preassembled unit is quickly installed with minimum space requirements. Additionally there is a considerable weight advantage. The drive weights around 40% less than a conventional direct drive motor. By comparison, the Renk AED weighs only 23 tons instead of the 35 tons of a direct drive motor of the same power.
Suitable for fixed pitch propellers as well as controllable pitch propellers the drive speed can be flexibly adjusted to the respective propeller requirements. The propulsion systems is built modularly and can be delivered in four sizes from 1.4 to 6 MW. For uses where the requirements are between sizes RENK simply adjusts the capacity of the bigger engine. In this way the complete range of capacities can be covered individually and economically. The motors work with low or mid ranged voltage and are designed –depending on size- for propeller revolutions of 190-450 rev/min.
Investing in new production & testing facilities
Besides pouring millions of dollars into research and development, marine propulsion manufacturers are also investing in new production and testing facilities. Earlier this year, Renk opened one of the largest and most modern test facilities in Europe for gear units at its headquarters in Augsburg. Whether for the shipbuilding, automobile or industrial sector: The multifunctional test facility is especially suitable for the testing of prototypes or special equipment. Renk will not only test its own special gearboxes and propulsion systems, but also those of other propulsion systems or propulsion component manufacturers. The test facility allows for a power capacity of up to 12 MW at 10 revolutions per minute and can take a torque of up to 11 million Nm.
Just this past June, Rolls-Royce Marine unveiled plans for a EURO 57 million plan to upgrade its azimuth thruster plant in Rauma, Finland, and consolidate its thruster assembly and testing to one site.
Rauma produces a wide range of mechanical azimuth thrusters for use on a wide range of applications including semi-submersible drilling rigs and drillships, tugs and offshore vessels. Rauma also produces thrusters for specialist vessels such as icebreakers and polar research ships.
Mikael Makinen, Rolls-Royce, President – Marine, says, “Our azimuth thrusters are one of our most important products, providing mission critical power and propulsion for some of the largest floating objects on the planet. To be able to make this significant investment in Rauma not only prepares us for future growth in this market, but is a vote of confidence in the capability and expertise of our people.””
Azimuthing thrusters rotate through 360 degrees, providing propulsion and maneuverability without the need for a rudder. The largest and most powerful thrusters from Rauma are the ARC type which power icebreakers including the Finnish vessel Fennica. They are among the largest products produced by Rolls-Royce and can each weigh up to 190 tonnes, providing 7.5Mw of power.
Two of the world’s largest floating structures are powered by another range of thrusters produced in Rauma, UUC underwater mountable thrusters:
The heavylift vessel Pioneering Spirit, owned by Allseas, which is used for decommissioning oil platforms, has13 UUC thrusters; and Shell’s Prelude, the world’s first floating LNG production facility, will feature three large UUC thrusters, for position keeping. The thrusters are installed in a novel arrangement that allows them to be removed and maintained within the ship.
The work to transform Rauma will begin immediately and is due for completion in 2020. The investment will include installation of a crane capable of lifting 200 tons, and at least six factory acceptance test rigs. Offices and IT systems will also be refurbished.
JULY 19, 2016 — Rolls-Royce will be presenting new MTU brand propulsion systems designed to meet IMO III and EPA Tier 4 emission regulations for commercial, offshore and military vessels and yachts
