INSULATION STRUCTURE OF CARGO TANK FOR LNG

摘要

PURPOSE: An insulation structure for a LNG cargo tank is provided to improve the sealing performance of a cargo tank by forming primary and secondary barriers with a corrugation membrane. CONSTITUTION: An insulation structure for a LNG cargo tank comprises multiple insulation panel parts(120), a secondary barrier(130), a spacer plywood(140), and a primary barrier(160). The insulation panel parts are coupled to an inner side(10) of a hull. The secondary barrier is coupled to the top of the multiple insulation panel parts. The spacer plywood is arranged on the top of the secondary barrier. The primary barrier is coupled to the top of the spacer plywood.
