LARGE DUAL-FUEL ENGINE FOR A LNG TANKER

The increase in demand for energy in convenient form has spurred activity in the field of LNG transport. Considerable advancement has been made in the handling equipment and tank systems, but the development of the propulsion machinery for these vessels has lagged due to the problems attending the utilization of LNG boil-off as fuel. A dual-fuel diesel engine has been developed that overcomes these problems. A description of this power plant is presented, with attention given to the auxiliary scavenge air supply, which permits the dual-fuel engine to operate at a high bmep without knocking, and the fuel ratio control mechanism, which controls the proportion of gas and liquid fuels used in the engine, is included in the discussion.
