ANCHORING STRUCTURE TO MINIMIZE THE HEAT INGRESS OF LNG CARGO

摘要

An anchoring structure of an LNG cargo is provided to reduce production of BOG(Boil Off Gas) inside the LNG cargo by using a rigid insulation material including glass fiber. An anchoring structure of an LNG cargo comprises a top cap(300), a body portion(100), and a bottom flange(200). The top cap is formed of a metal material and is joined with a membrane(2) by welding. The body portion is integrally formed, on the bottom of the top cap, of insulation material including glass fiber to minimize heat transfer from the inner wall of the cargo toward the top cap. The bottom flange is integrally formed on the lower part of the body portion, and anchored by a stud bolt(S) formed on the cargo space inner wall.
