MAN wins Seaspan ferry propulsion system order

Artist's impression of ferry
The two 149 m LNG battery hybrid RO/RO ferries recently ordered by Canada’s Seaspan Ferries (see earlier story) may look a lot like the pair delivered to the operator last year, but they are being built by a different shipbuilder and will have a different propulsion system supplier.
Damen Shipyards Gorinchem B.V. is to build the vessels at its Mangalia, Romania, yard and has placed an order with MAN covering the provision of MAN 35/44DF dual-fuel engines, fuel gas-supply systems and the main electric systems, including batteries.
MAN says that, though Seaspan had initially been minded to build repeats of the two previous ferries, a live performance of its MAN 35/44DF engine demonstrated that a fully-integrated MAN solution could better fulfill the owner’s requirements.
MAN Energy Solutions will provide the solutions in association with Aspin Kemp & Associates (AKA), in which it has a 40% stake. AKA specializes in power supply, energy management and drive systems for marine and industrial applications.
Similarly, MAN Energy Solutions’ fuel-gas specialist, MAN Cryo, will provide the new ferries’ fuel gas-supply system.
“We are very pleased to have won this order, and that our case was compelling enough for the customer to change an existing technical specification to our favor,” said Wayne Jones OBE, Chief Sales Officer and Member of the Executive Board, MAN Energy Solutions. “It really showcases our strategic direction of developing sustainable technologies and solutions, and how we have expanded our business in recent years. This is a move that is now paying off as evidenced by the key roles that AKA and MAN Cryo play in this significant order.”
Jason Aspin, CEO of Aspin Kemp & Associates, added: “This order represents a strategic milestone for AKA due to many factors. First off, it showcases the successful MAN and AKA partnership, offering highly innovative, full turn-key systems to operators. Secondly, it is a great opportunity for AKA’s technologies to be deployed in our backyard in Canada with a leading and forward-thinking owner like Seaspan. And lastly, with a technology where AKA has been a first mover in several initiatives for over a decade, this demonstrates that the marine industry is opening to the value that hybrid systems provide in meeting their environmental reduction targets while at the same time reducing their operating costs. We are very excited to see this project kick into full gear and look forward to participating in a successful outcome for all stakeholders!”.
MAN Energy Solutions’ scope of supply for each shipset comprises:
  • 2 × MAN 9L35/44DF Diesel/Gas-electric propulsion system
  • 1 × MAN Cryo Fuel Gas Supply System including a 209 cu.m tank
  • 1 × AKA main electrical system
  • 1 × AKA 2-MWh energy storage systems
  • 1 × AKA low voltage distribution system .
The MAN hybrid-system solution in combination with a fully integrated MAN Cryo FGSS that is exactly adjusted to the engines gas-flow requirements, offers reliable operation in gas mode – especially in view of the ferry segment’s typical frequent and high load-fluctuations – and even with low methane numbers. For Seaspan, it was essential to avoid any diesel operation due to environmental and ecological reasons.
High system efficiency and the lowest emissions will also be achieved by having just one of two DF engines online at a time and at high load. Being able to operate with a one-engine-online concept means significant savings in fuel costs, running hours and therefore spare parts/maintenance costs.
The propulsion and battery hybrid system, integrated by AKA, provides sufficient propuslion power in all operational modes to serve Seaspan’s requirements to maintain its routes on time, fuel-efficiently, and with a minimal carbon footprint.
Additional AKA hybrid features for this project include peak shaving under rough conditions and maneuvering, enhanced dynamic support during ship acceleration, and zero-emissions operation at the terminal.

Teekay's next gen shuttle tankers will burn LNG and recovered VOCs

JANUARY 9, 2018 — Four next generation shuttle tankers on order for Teekay at shipbuilder Samsung Heavy Industries (SHI) feature a broad range of Wärtsilä's latest technology innovations that are expected to reduce annual emissions of CO2 equivalents by more than 40 percent, compared to conventional shuttle tankers.
In addition to operating on Liquefied Natural Gas (LNG) as the primary fuel, the ships' dual-fuel engines will also be able to run on a mixture of LNG and recovered Volatile Organic Compounds (VOC) – the gas evaporating from the oil cargo tanks during loading.
By utilizing the recovered VOC as fuel rather than venting it to the atmosphere, the harmful emissions will be eliminated and the ships' bunker needs will be significantly reduced.
The concept also means that NOx emissions from the engines' exhaust will be reduced by more than 80 percent, SOx emissions will be almost entirely eliminated, while particulate emissions will be reduced by more than 95 percent.
These environmental benefits are matched by equally important economic advantages, with a significant reduction in fuel consumption compared to conventional solutions.
"Together with Teekay, we have developed a concept that takes the shuttle tanker sector into a new era, and which is further evidence of Wärtsilä's ability to transform shipping by developing and utilizing the very latest technologies," says Roger Holm, President, Wärtsilä Marine Solutions. "These ships will have tremendous operational flexibility with unmatched maneuevring capability, and will achieve what all operators are striving for today, namely optimal economic and environmental performance."
"This new shuttle tanker design will set new standards for both fuel consumption and CO2 emissions," says Terje Rusdal, Project Manager at Teekay.
Among the many innovative features of the design is the Wärtsilä Hybrid system, on which the power distribution will be based. The Hybrid system uses batteries for fuel savings, peak load shaving, and added overall system redundancy. This directly impacts the main machinery, resulting in fewer running hours with correspondingly lower maintenance time and costs.
Wärtsilä's broad scope of suppy also includes the full electric and automation system, which includes the Wärtsilä Low Loss Hybrid (LLH) system and batteries, the Wärtsilä LNGPac fuel storage and supply system, the Wärtsilä VOC system for recovering and liquefying the VOC with a storage and supply system, Wärtsilä 34DF dual fuel gas engines, the fuel mixing system with liquid VOC and LNG as the main fuel for the engine, gas turbines to handle the surplus gas, Wärtsilä cargo and ballast pumps and a Wärtsilä inert gas generator.
Also included in Wärtsilä's integrated solution for this vessel concept is Eniram's Vessel Performance Management system. Eniram, a Wärtsilä company, will provide a data collection platform having the capabilities to optimize the vessel's operations, while also providing the owners with analytics and reporting. The Performance Management system ensures that the full potential of the vessel as well as the fleet, will be utilized.

VIDEO: World first conversion takes LNG-fueled OSV hybrid

Energy storage solution replaced one of vessel's four LNG fueled enginesEnergy storage solution replaced one of vessel's four LNG fueled engines
OCTOBER 13, 2017 — Eidesvik Offshore's Viking Princess has become the world's first offshore vessel to use battery power to reduce the number of generators on board. The five year old Norwegian vessel now runs on a combination of a battery pack for energy storage and three LNG-fueled Wärtsilä engines.
The vessel's newWärtsilä energy storage solution provides balancing energy to cover the demand peaks, resulting in a more stable load on the engines. The technology is similar to that used in hybrid cars: it prevents the engine load from dipping, and uses the surplus to re-energize the battery, which can be charged as needed.
Wärtsilä's remote monitoring and operational advisory services support the daily operation of the vessel, ensuring efficient and optimized operations.
The new energy storage solution will improve engine efficiency, generate fuel savings and reduce greenhouse gas emissions.
Viking Princess completed sea trials and the system was handed over to Eidesvik Offshore on October 9.
There is significant potential to save fuel through improved engine efficiency, as the operating profile of supply vessels is highly variable. When using the Wärtsilä installed energy storage system on board Viking Princess, the fuel saving potential can be up to 30 percent in various operations and CO2 emissions can be reduced by up to approximately 13–18 percent per year, depending on operational conditions and requirements.
Additionally, the hybrid solution will provide a more optimal load on the engines, while the intervals between engine maintenance can be extended.

The contract to replace one of the four engines on Viking Princess with battery power was signed in May.
"Eidesvik and Wärtsilä's partnership dates back to 2003 when our ship, the Viking Energy became the first offshore supply vessel powered by LNG fuel. Now, together, we are again introducing a world's first, with the Viking Princess becoming the first offshore vessel in which batteries reduce the number of generators aboard the ship. We are grateful to Wärtsilä for providing the technology to make this possible," says Vermund Hjelland, President Technical Department, Eidesvik Offshore.
"This is a truly forward-looking solution, and we congratulate Eidesvik Offshore for having the vision to appreciate the benefits that hybrid energy system offers. In addition to the fuel consumption and environmental advantages, the conversion also reduces maintenance costs and contributes to more efficient operations. The success of this project will impact the future of the entire shipping industry," says Sindre Utne, Manager Projects and Operations, Wärtsilä Norway. "Wärtsilä's advantage lies at the most advanced level of integration related to hybrid technology for marine applications. It is a combination of expertise in both engines and electrical and automation systems, as well as digital solutions."

The latest MTU propulsion solutions for mega yachts will be on display September 27-30 at the Monaco Yacht Show where it= will be presenting its advanced-design Series 4000 engines for IMO III, including MTU's SCR system.
A model of the new close-to-production prototype MTU hybrid system based on the 16V 2000 M96 engine will be on display.
Yacht owners will benefit from the combination of high performance and efficiency in addition to the comfort and luxury of silent, low-vibration cruising.
The MTU hybrid propulsion systems are designed on a modular basis and, depending on the diesel-engine series, will cover various electrical outputs within series solutions.
"Electric motors and hybrid propulsion systems from MTU will be an important mobility component for marine propulsion systems of the future," says Stefan Müller, Head of Application Center Marine & Offshore at MTU. "MTU offers a proven, series solution, which combines the mechanical and electrical components to provide optimum performance through MTU's automation system."
MTU has delivered an innovative hybrid propulsion system designed to meet the client's specific requirements for "Sailing Yacht A", the world's largest sailing yacht, which was commissioned in spring 2017. This is a combined diesel-electric propulsion system, which offers seven different propulsion modes. When needed, a high speed can be reached using the combination of both diesel and electric propulsion, but can also provide slow, extremely efficient cruising with very low vibration levels and reduced fuel consumption.
In addition to this exceptional project, MTU has also completed additional hybrid projects, in partnership with the Heesen Yachts shipyard, for example. With its "Nova Hybrid" project, Heesen is offering a 50-m fast displacement luxury yacht in its portfolio, which features a combination of 1,200 kW of diesel power (2 x MTU 12V 2000 M61) and 2 x 110 kW of electrical output. The all-aluminium yacht can travel at a speed of 9 knots on its electrical power source alone, while offering completely silent cruising.
Propulsion systems for megayachts (IMO III + II)
MTU will be showcasing its latest generation of Series 4000 engines at the Monaco Yacht Show, which comply with IMO III emission regulations when combined with MTU's SCR system. The high performance engines for yachts will be available as 12, 16 and 20-cylinder versions covering the power range from 1,920 to 3,900 kW. MTU will still include IMO II engines in its range.
MTU's new SCR system
With the new integrated solution for IMO III, consisting of MTU's propulsion system and SCR exhaust gas aftertreatment system, the customer benefits from an optimally matched system. Taking up little space and offering flexible installation, it features an excellent power to weight ratio. The SCR system from MTU is also flexible in operation: depending on the area (IMO II or IMO III) in which the yacht is sailing, the SCR system can be switched on or off as required.
MTU's SCR system is a fully controlled system, with real-time nitrogen oxide (NOx) measurement upstream and downstream of the SCR. This also regulates the amount of reactant injected to ensure that it is precise and ideal regardless of the operating conditions. The first IMO III yacht propulsion system with two 16V 4000 M73R MTU engines will be used in a new 80 m megayacht built by the Bilgin Yachts shipyard in Istanbul.

Available with six, eight or nine cylinders, close to sixty engines have been sold to date. Orders have been received for various vessel types from all over the world including Norway, U.K, Spain, Canada, China, Singapore and New Zealand.
Last month, Rolls-Royce also launched a new a vee-line version of the engine to address a bigger portion of the marine and land market.

Damen Galati to build two hybrids for BC Ferries

Hybrid diesel electric may get later conversion to all electric

JUNE 7, 2017  — BC Ferries has awarded Damen Shipyards Group a contract to build what it calls "two new minor class vessels" that are scheduled to go into service in 2020.
Damen, which will build the vessels at its Galati, Romania. shipyard has entered into an agreement with Point Hope Shipyards of Victoria, BC. to provide technical and warranty support for the new vessels, ensuring repair and maintenance activities will be performed in British Columbia.
The first of the new vessels will be deployed on the Powell River – Texada Island route, replacing the 59-year old North Island Princess, which will be retired from the BC Ferries fleet. The second vessel will replace the Quadra Queen II on the Port McNeill – Alert Bay – Sointula route. The Quadra Queen II will become a relief vessel, allowing for fleet redeployments and the retirement of the 53-year old Howe Sound Queen.
The agreement is a design-build, fixed-priced contract that provides BC Ferries with substantial guarantees related to delivery dates, performance criteria, cost certainty and quality construction. The total project budget, which includes financing and project management costs, is approximately C$86.5 million CAD.
The project is partially funded by the Government of Canada.
The two minor class vessels will have the capacity to carry at least 44 vehicles and up to 300 passengers and crew. They will have a number of key features that support BC Ferries’ goal to be efficient and environmentally responsible throughout its system.

Highlights include:
A hybrid diesel electric - battery power generation and propulsion system that uses on board electric battery power for operation of the vessel. Electric propulsion is quiet, smooth and efficient compared to traditional diesel propulsion. The design allows for future expansion of the on board battery capacity to permit full electric operation when the shore-side charging capacities are available.
Engines that operate on ultra-low sulfur diesel fuel, which has lower environmental impact than regular marine diesel oil. The Tier III compliant engines also have low NOx and particulate emissions.
Hull, propeller and thruster design that minimizes underwater radiated noise.
Arrangements to minimize shipboard vibration and airborne noise to improve conditions for communities, passengers and crew.
A fully contained waste water handling system which eliminates discharges to the sea.
BC Ferries says that it issued a Request for Expressions of Interest (RFEOI) for the design and construction of the vessels to leading shipyards in Canada and around the world in March 2016.
It says in the lead up to this process, it raised awareness of the upcoming tender to Canadian shipyards through such forums as the Canadian Ferry Association, the Association of British Columbia Marine Industries and local and national industry events.
Canadian shipyards were invited to participate in the competitive bidding process.
BC Ferries received responses from 28 national and international shipyards and short-listed 12 shipyards to proceed to the Request for Proposal (RFP) stage, including five Canadian shipyards.
BC Ferries received four compliant RFP responses, however, none of the shortlisted Canadian shipbuilders submitted a bid.

Rolls-Royce to supply engines for five LNG electric hybrid ferries

Ferries are being built to Multi Maritime MM125FD LNG design.Multi Maritime

JUNE 1, 2017 — Rolls-Royce has signed a deal to supply 15 Bergen gas engines to Norwegian Ferry Company, Torghatten Nord AS. They will power five 134 m passenger and car ferries of Multi Maritime MM125FD LNG design.
Kjell Harloff, Rolls-Royce, Vice President, Engines – Marine said: "Since the introduction of our first marine gas engines ten years ago, Rolls-Royce has delivered more than 700 gas engines on land and at sea accumulating over 25 million running hours of operating experience. We have proved that the Bergen lean-burn, pure gas, medium-speed engine range, combined with efficient hull designs, can help customers, like Torghatten Nord, cut their ships' emissions and fuel bills significantly.
The five ferries will all operate at the busy Halhjem-Sandvikvåg route in Western Norway and will be equipped with a gas electric hybrid propulsion system. The battery system will be arranged with capability for fast charging from shore.
All 15 engines are nine cylinder in-line in C26:33L9AG gensets The engine can operate on variable speed to reduce both fuel consumption and emissions. The C-gas engine has an operating speed of 1,000 rpm and power of 2,430 kW.
Two of the vessels will be built at the Vard Brevik, shipyard in Norway while the other three will be built at the Tersan Shipyard, Turkey. The vessels are expected to enter service in January 2019.
The Bergen C26:33 series engines reduces total greenhouse gas (GHG) emissions by about 20 % compared to a similar diesel engine, even including the effects of methane slip, and are IMO Tier 3 compliant without the need of exhaust after treatment system.
Engine rooms on gas powered vessels also stay much cleaner, saving operators time and money by reducing the frequency of cleaning tasks and the cost of chemicals.
The whole LNG system is designed for safety with double walled stainless steel containment.
Bergen C26:33 series engines are in operation across a range of vessel types including cargo vessels, PSVs and tugs as well as passenger vessels.
Torghatten Nord currently has 33 ferries and 10 express boats in operation in Norway. Four earlier LNG ferries, with Bergen gas engines, were built by Polish shipbuilder Remontowa and have been operating on two routes serving Lofoten.

MAN engines power hybrid port patrol boat

MAY 24, 2017 — Zoetemeer, Netherlands, headquartered MAN Rollo has supplied two MAN D2676LE424 engines for the RPA8, a hybrid patrol boat, commissioned by the Port of Rotterdam Authority at Kooiman Shipyard (see earlier story).
When putting out a tender for the patrol boat, the Port of Rotterdam Authority defined a number of principles, including the cost of ownership, emission reduction and minimizing of wave generation.
The tender also specified that the patrol boat be equipped with a hybrid propulsion system combining diesel electric and diesel direct power; diesel electric fed to one of the engines up to a speed of 25 km/h and diesel direct for both main engines at speeds between 25 km/h and 35 km/h.
By correctly loading the engines, the RPA 8's combustion is more efficient, which reduces fuel consumption and emissions.
An aftertreatment system further limits the emission of hazardous substances.
Additionally, heat recovered from the engines' cooling water system heats the deckhouse.
"In this contract, we wanted to show that it is possible to save fuel by effectively aligning the combination of diesel and electric power," says Maarten Kooiman, Head of the Design Bureau at Kooiman Engineering. The shipyard also collaborated with the Van Oossanen group, which designed a hull specifically for the RPA 8.
The hull is a combination of two patented inventions: the Fast Displacement Hull Form and the Hull Vane. This minimizes wave generation and results in a 20% reduction in vessel resistance at top speed. To reach the desired top speed (35km/h), 736 kW is sufficient power.
"This allows us to install smaller main engines," says Maarten Kooiman. "The information gained from various engine suppliers showed that MAN Rollo could supply engines in the required power range and at a low lifecycle cost."
The Port of Rotterdam Authority is striving to become a sustainable port. "Our engines are in keeping with this," says Karel Schuurman, Sales Manager at MAN Rollo. "The engines are very modern and feature the latest common rail fuel injection technology. As a result, their fuel consumption is low and the exhaust emission levels are lower than that prescribed by the current global emission standards."
This is a major advantage, because the patrol boat will operate in a busy urban area with a lot of waterborne traffic. The two MAN D2676LE424 engines supplied by MAN Rollo each generate 382 kW@1,800 rpm and, says Mr. Kooiman, are "the best option for the RPA 8 with respect to dimensions and weight."
MAN Rollo Rollo is part of the international trading and service organisation Pon, one the largest family-owned businesses of the Netherlands.

Seaspan Ferries commissions LNG hybrid duo

APRIL 11, 2017 — Canada's Seaspan Ferries Corporation (SFC) officially welcomed two new, state-of-the-art dual-fueled/hybrid (liquefied natural gas, diesel and battery) vessels to its fleet during a double commissioning ceremony held at its Tilbury Terminal, Delta, BC, on April 9.
The Seaspan Swift and Seaspan Reliant, the first eco-ferries of their kind in North America, were formally christened by sponsors Christy Clark, Premier of British Columbia, and Anisa White, wife of Doug White III, Councillor and Chief Negotiator for Snuneymuxw First Nation.
Following construction at Sedef Shipyard in Istanbul, Turkey, the Seaspan Swift arrived in December 2016 and entered operation in January 2017, while the Seaspan Reliant arrived in late February and is scheduled to begin service later this month. The 148.9 m long ferries which can accommodate up to 59 53-ft trailers, are the first new vessels added to SFC's fleet since 2002.
Seaspan Swift arrived from shipbuilder in December 2016 

Ulstein firms up order for giant plug-in hybrid ferry

FEBRUARY 17, 2017 — Following up on the LOI signed last month, Color Line and Ulstein have signed a firm contract for the construction of what will be the world's largest plug-in hybrid vessel.
Ulstein won the contract in competition with several other shipyards.
"It is very gratifying that the Norwegian shipbuilding industry has proven its competitiveness internationally, and that Color Line contributes to the further development of the Norwegian maritime industry," says CEO Trond Kleivdal at Color Line.
"We are very pleased that Color Line decided to proceed from a Letter of Intent to a firm contract on the construction of this hybrid vessel. This is an important milestone for us, and we are looking forward to the further cooperation with Color Line," says Ulstein Group CEO Gunvor Ulstein.
The 160 m vessel, with the working title Color Hybrid, will carry 2,000 passengers and 500 cars and will provide significantly increased capacity on the Sandefjord-Strömstad route between Norway and Sweden along with expanded and improved services on board .
The new vessel will be built according to Norwegian flag requirements and registered in the Norwegian Ordinary Ship Register (NOR). Color Line is currently the only company in the international passenger and freight traffic to and from Norway with ships registered in the Norwegian Ship Register and with Norwegian headquarters.

La Naval delivers ABC-powered hybrid RoPax ferry

La Naval delivers ABC-powered hybrid RoPax ferry
JUNE 29, 2016 — Spanish shipbuilder Construcciones Navales del Norte—La Naval — has now delivered Texelstroom, one of the world's first  hybrid RoPax ferries.
The 135 m double ender has been built for Royal N.V. Texels Eigen Stoomboot Onderneming (TESO) and is designed to transporting up to 1,750 passengers and 350 vehicles between the port of Den Helder, Netherlands,  and the island of Texel.
Anglo Belgian Corporation (ABC) supplied the four medium speed main engines, including two dual fuel (CNG + diesel) generator sets that deliver 2 MW each at 1,000 rpm and two diesel generator sets that develop 2 MW each at 750 rpm.
For the dual fuel engines, an air/gas mixture is injected in the cylinders, which is then compressed. A small pilot injection of diesel ensures the ignition. Natural gas (CNG) is more environmentally friendly and has as one of the main advantages that hardly any soot or sulfur dioxide is released during the combustion.
An important advantage of ABC's dual fuel engines is a very flexible fuel system that considerably increases efficiency. The ignition system makes it possible to work with different gases of low calorific value and fluctuating ignition quality.
Texelstroom will generally sail using its dual fuel engines every hour between 6 am and 10 pm. The engines are designed to have sufficient power in the tidal conditions in which the ship operates for the approximately 20 minute crossing between the mainland and the largest Dutch Wadden Sea Island Texel.
In normal weather conditions, Texelstroom will use only one dual fuel generating set during the majority of the crossing with the engine coordinating with the battery packs on board.
Redundancy was taken into account from the concept stage of the ferry. In cases of extreme urgency, the hybrid ferry will have to make the crossing from Texel to the mainland (and vice versa) at high speed. Therefore, two back-up diesel generating sets were also provided.
In addition to the two storage tanks for the compressed natural gas, a 700 sq.m solar photovoltaic panel field is also installed on the roof of the ferry, with the energy that it produces being stored in high capacity electric batteries that are part of the ship's advanced energy management system. This energy can then be used at peak times for either propulsion or electricity consumption on board of the ferry.
Cees de Waal, Director of TESO, stated: "With Texelstroom, TESO wanted to achieve its ambition where environmental benefits, cost control and quality improvement go together. The ship embodies the latest technologies for reducing emissions. This next-generation ferry will sail our passengers in a comfortable and efficient way across the Marsdiep. With regards to the propulsion, it was very important to choose environmentally friendly and reliable engines.
"Jean-Pierre Props, Area Sales Manager at Anglo Belgian Corporation, said, "We want to thank Royal TESO for their confidence in our engines and wish them all the best in the continued operation of the ferry service between Texel and Den Helder."
