OPERATING EXPERIENCE WITH LNG TANKERS

This paper deals with the practical and economic aspects of the operation of LNG ships, including unusual problems and conditions, cargo handling and containment, use of cargo boil-off gas as fuel, ship handling and mooring, cargo measurement, economics, maintenance and repair, crew training, ballast water systems, routing and round trip times. The above topics will be discussed specifically on the basis of operating experience with two 718500 cubic meter LNG ships, the s/s "Polar Alaska" and s/s "Arctic Tokyo," which, at the time of delivery of the paper will have concluded about 25 and 21 round voyages, respectively, between Nikiski, Alaska, and Negishi, Japan. These topics are those in which it can be expected that there will be differences as compared with standard crude tankers. One conclusion which is reached is that in several specific areas, including most operating costs, maintenance and repair time, and general vessel operation, little, if any, difference is encountered as compared to standard crude tankers. Another conclusion reached is the need for a highly trained crew, better instrumentation, and shoreside help with controls at each voyage.
