Abstract

The first roro/passenger ferry in the world to be applied LNG fueled engines entered service in Norway in February, 2000. The reason applied LNG fueled engines is that the Norwegian have a sense of environment strongly, and LNG is easy enough to supply stably.
LNG is composed of methane mainly, and not include sulphur. Therefore, it is possible to produce the reduced NOx, CO2 and zero SOx emissions by the LNG fueled engines. It provides the environmental benefit. The engines burn a combination of gas and air, and feature both a pre- and main chamber designed for lean gas/air ratio. The pre-chamber technology ensures very low NOx level. The low NOx emission achieves below of 150 ppm and 10-20 percent drop in CO2 in comparison with oil engines.
This paper describes an outline of the ferry applied LNG fueled engines, a demand for the engine and an outlook for LNG powered ships.
