The GTV LUCIAN is a 29,000-cu m liquefied gas carrier designed, utilizing the Kvaerner-Moss tank system, as a world trader. The vessel is powered by a 20,000-hp heavy-duty marine gas turbine, equipped to burn a wide range of heavy residual fuels in combination with LNG cargo boil-off. Since entering commmercial service in June 1975. the LUCIAN has traveled almost 150,000 n.m., and accumulated approximately 9000 fired hours on the propulsion machinery. Virtually all of this service occurred

... heavy residual fuels, with some operation in a dual-fuel mode with cargo boil-off, when LNG cargo was being carried. This paper briefly describes the vessel arid her propulsion machinery, with particular emphasis on those features which are unique to this application. The operating experiences acquired during the last two years are then reviewed. Operating problems encountered with the propulsion machinery are discussed in depth, as are the solutions developed to resolve them.
