MAN to equip first LNG-powered fishing vessel
MAN Diesel & Turbo has been selected to provide a complete propulsion package and fuel-gas system for the worldâ€™s first fishing vessel with LNG propulsion. The 86-metre purser-trawler Libas will be built by Cemre Shipyard in Turkey.
Libas will feature a MAN 6L51/60DF main engine, Renk gearbox, MAN Alpha propeller system and MAN Cryo LNG fuel-gas system with a 350 cubic metre tank. Libas has been ordered by Norwegian fishing company Liegruppen and is designed by Salt Ship Design.
â€˜This is a pioneering project. At MAN we are convinced that low-emission gas fuels are the silver bullet to decarbonising the shipping industry and we have made it our mission to guide our customers through that transition,â€™ said Wayne Jones, chief sales officer with MAN Diesel & Turbo.
The delivery of the new LNG-propulsion package is part of MANâ€™s wide ranging engagement for the establishment of LNG as a marine fuel. Calling for a Maritime Energy Transition, the company considers the use of natural gases as the fuels of choice in global shipping as the most promising way to supporting the goal of a climate-neutral shipping industry. Launched in 2016 after COP 21, MANâ€™s initiative has since found broad support within the shipping industry and politics.
â€˜We offer a full system approach with regards to gas propulsion,â€™ said Lex Nijsen, Head of Four-Stroke Marine at MAN Diesel & Turbo. â€˜This includes new builds as much as retrofits of existing vessels. In 2017 MAN has retrofitted the worldâ€™s first container vessel to LNG and more projects are being realised as we speak.â€™
He commented that winning the order for the propulsion system for the new Libas is a noteworthy development for the company.
â€˜Our ability to provide this efficient, low-emission, proven LNG- fuelled propulsion package â€“ a worldâ€™s first for this environmentally sensitive segment â€“ really puts our credentials as a system provider on display,â€™ he said.
The MAN Cryo fuel-gas system incorporates a 350 cubic metre vacuum insulated cylindrical type C tank, a TCS/coldbox with process equipment, manifold and instrumentation, an emergency shut-down system and a bunker station for supply of LNG to tank.
The system is designed for a net tank volume of 330 cubic metres of LNG and temperatures down to -163Â°C. The tank stores LNG at the lowest possible temperature and pressure until it is evaporated and supplied to the dual-fuel MAN 6L51/60DF main engine, according to consumption requirements.
MAN Diesel & Turboâ€™s uprated MAN L51/60DF engine successfully passed its Type Approval Test at the end of 2017 where a nine-cylinder test engine had an output of 1150 kW/cylinder at a nominal speed of 500/514 rpm. The engine can be employed both as marine main engine and auxiliary engine and ran on both fuel-oil (DMA) and natural gas on the testbed.
