BUILDING AND OPERATING EXPERIENCE OF SPHERICAL TANK LNG CARRIERS

A summary of the analytical and experimental bases of the spherical tank LNG carriers of the Kvaerner-Moss design is given. Primary attention is paid to a complete description of the experience from building spherical tanks is both 9% nickel steel and aluminum, including such critical areas as welding, non-destructive testing, maintenance of tolerances and repairs of defects. The results of stress and temperature measurements made on the cargo tanks under test are compared with earlier predictions from analytical studies. Operating experience with the cargo system is reported. The paper is appended with status reports of LNG trades presently operated, projects in construction and planned; ships in operation, in construction and planned.
