MAN Diesel And DSME To Jointly Develop Gas Technology

Posted on February 23, 2010

MAN Diesel signed a development agreement with Daewoo Shipbuilding & Marine Engineering Co. Ltd. (DSME). The two companies have agreed to jointly develop and exploit the adaptation of DSME’s high-pressure cryogenic gas-supply system for installation with MAN B&W ME-GI engines.

The ME-GI engine is a gas-injection, dual-fuel, low-speed diesel engine that, when acting as main propulsion in LNG carriers or any other type of merchant marine vessel, can burn any ratio of fuel-oil and gas, depending on the energy source available on board and dictated by relative cost and owner preference.

MAN Diesel has decided to make a full-scale demonstration and performance verification test of the GI principle for all kinds of marine applications on its 4T50ME-X R+D test engine, which will be rebuilt as a 4T50ME-GI engine ready to operate on natural gas by end-2010.

The agreement covers the terms for jointly deciding a time schedule for developing and installing DSME’s cryogenic, high-pressure gas-supply system on the test engine at MAN Diesel’s test facility in Copenhagen. The gas-supply system will subsequently be developed for general use on MAN B&W ME-GI engines, and will ultimately be adopted as an integral part of the engine’s gas fuel-supply system for such applications where a cryogenic gas-supply system is applicable.
