Tokyo - Mitsui O.S.K. Lines Ltd. (MOL) announced that it has been decided that Mitsui Engineering & Shipbuilding Co. Ltd. (MES) and MOL will conduct a gas injection demonstration run utilizing a temporarily-modified electrically-controlled type slow speed diesel engine. The engine is designed, manufactured and delivered to a shipyard with oil injection specifications for one of the MOL newbuild vessels. However, during manufacturing, it will be temporarily modified to an electrically-controlled gas injection duel fuel slow speed diesel engine. The engine will be run with vaporized LNG at MES Tamano Works in the first half of 2013. LNG has recently been highlighted as one of the potential propulsion fuels for future ship design.
