Service experience with 125,000-m/sup 3/ LNG vessels of spherical-tank design
Serving the Indonesia-Japan LNG project - the largest now in operation - are eight spherical-tank-design vessels (seven dedicated) with capacities of 125,000 m/sup 3/ carrying over 8 million tons of LNG annually. Details are presented on the project's development and start-up, the vessels' construction and design, the preparations involved in placing the ships in service (including extensive crew training and proper outfitting), the gas-trials procedures used, the voyage characteristics, and the improvements made to the vessels based on their service experience (including the relocation of the discharge-line check valves, extension of the tank fill lines, modification of the pump motor insulations, and several other changes made to the cargo and ballast system components, the main reduction-gear lube-oil spray system, and the boilers' internal components). The cargo control-system design and the reliability of the electronic control systems have proved to be the most critical factors affecting the LNG tankers' performance.
