Marine Diesel Engine: New Dual-fuel Engine in MAN Portfolio

A new dual-fuel marine diesel engine variant from MAN Diesel & Turbo, the ME-LGI,  runs on liquid gas fuels – methanol, LPG, dimethyl ether (DME), and (bio-) ethanol as well as other, low-flash-point fuels – building on the manufacturer’s successful LNG /HFO dual-fuel ME-GI low speed engine plant introduced last year. MAN developed the ME-LGI engine in response to interest from the shipping world in using alternatives to heavy fuel oil. Methanol and LPG carriers have already operated at sea for many years and many more LPG tankers are currently being built as the global LPG infrastructure grows; in themselves a ready market once a suitable dual-fuel engine became available.Sure enough,  the new engine, unveiled on 1, July 2013 was snapped up as MAN signed a Letter of Intent with Vancouver-based Waterfront Shipping for the installation of four MAN ME-LGI engines which will run on a blend of 95% methanol and 5% diesel fuel.

Container ship operators looking for the lowest possible fuel oil consumption at any engine load will be interested to hear word from MAN Diesel & Turbo that the first super-long-stroke large bore two-stroke engine specifically designed for them, the S90ME-C9.2, has just successfully completed trials on Hyundai Heavy Industries Engine & Machinery Division’s  test bed. Marine Diesel Engine MAN S90ME-C9.2: Photo credit Man Diesel & Turbo The new engine, of reduced size for container ship engine rooms (although the largest ever designed by MAN) is based on the VLCC-optimised S90ME-C8 engine, as operators look to reduce operating costs through slow steaming, turbocharger cut out and low-load engine optimisation; all of which are offered by the new engine. Engine Design Concept – MAN S90ME-C9.2 Low-speed two-stroke main engines of MAN’s existing MC type, with a chain driven camshaft, have limited flexibility with regard to fuel injection and exha...

Wärtsilä announce the addition of two new 62 and 72 bore engine series to their RT-flex two stroke, low speed programme. The new engines offer significant benefits to both shipowners and operators by way of high propulsion efficiency, reliability, and optimised total cost of ownership. The two new engine series employ well-proven Wärtsilä low-speed technology, together with electronically-controlled fuel supply and control. Wärtsilä's licensee partners in Asia are closely involved in the manufacturing process and all Wärtsilä licensees will have the right to build the new engines. Availability of the 62 is Sept 2013 and 2014 for the 72. [More]
