CARGO TANK STRUCTURE OF LNG LINE

摘要

PURPOSE: A cargo tank structure is provided to solve a sloshing and to increase a volume of a tank by installing bulk heads in an upper plate toward a stem and a stern in a lattice shape. CONSTITUTION: A bulk head(12) is installed in the center of a lower plate(11) in a square shape. Bulk heads(14,15) are installed in an upper plate(13) at regular intervals toward a stem and a stern. Bulk heads(16,17) are installed in the widthwise of a tank. Thereby, the bulk heads are installed in a lattice shape. The bulk heads(16,17) are welded only in the upper plate without welding in side plates(18,19). Thereby, the volume of a cargo tank is increased sufficiently.
