High oil prices and an increased focus on exhaust emissions from ships make natural gas in form of LNG an new a promising fuel in the short sea sipping segment. Availability of LNG in general and in small scale is improving. The paper will describe and discuss the technology of LNG storage and bunkering. Gas engines are mainly designed for land based power production and need adjustments for ship propulsion. Requirements for gas engines in ship operation are discussed. Interim guidelines for gas fuelled ships are under development under IMO and Norway is coordinating this work. The paper will preset some of the work and the challenge for design of the propulsion system for gas fuelled ships. Some experience of gas fuelled ships in Norway will be presented. A new series of five large LNG car ferries will be in operation late 2006 and two supply vessels have been in operation in two years. Both technical solutions, economical aspects and emission levels, will be discussed.
