The 87,500m3 SPB LNG carriers-"POLAR EAGLE" and "ARCTIC SUN"- have been providing regular, trouble-free service between Alaska and Japan since they commenced operation in 1993. In total they have delivered 100 cargoes to Japanese buyers as of August 9, 1996. It should be emphasized that regular service has been maintained even in rough winter seas reaching 12 on the Beaufort scale ( 12 is defined as the roughest state, with winds faster than 33m/s and waves higher than 14m).

The two ships were dry-docked in IHI Yokohama shipyard to confirm the complete condition of cargo tanks, tank supports and insulation to the customer's full satisfaction. The many advantages of SPB LNG carriers have been proven through actual voyages, including strength of the containment system, good maneuverability, good stability, low boil-off rate and simple operation. Utilization of SPB technology has created new areas to contribute to LNG transportation. One of them is new ways of reducing LNG transportation cost, which is the topic of this paper.
