본 발명은 액화가스 화물창의 펌프 타워 베이스 서포트에 관한 것으로, 1차 방벽(primary barrier)와 2차 방벽(secondary barrier)의 연결구조에서 균열진전을 막을 수 있는 분리 구조로서, 1차 방벽의 크랙 발생으로 2차 방벽 까지 연쇄적으로 손상되는 것을 효과적으로 막을 수 있으며, 펌프 타워의 횡 방향 움직임을 충분히 구속할 수 있는 강도를 가지도록 1차 단열박스의 상면에 1차 방벽 연결 부재를 볼팅(bolting) 연결하고, 펌프 타워 서포팅(supporting)을 위한 충분한 강도/강성을 가지도록 최적의 구조로 배치함으로써, 펌프 타워의 횡 하중에 의한 피로손상을 효과적으로 방지할 수 있다.
The present invention relates to a pump tower base support of liquefied gas cargo, which is a separation structure to prevent a crack from being generated in a connection structure of a primary barrier and a secondary barrier, and effectively prevent continuous damage to the secondary barrier with generation of a crack in the primary barrier. Moreover, a primary barrier connection member is bolted to an upper surface of a primary insulation box to have strength to thoroughly restrict movement in a transverse direction of a pump tower, and an optimal structure is provided to have enough strength and rigidity for supporting the pump tower. Therefore, fatigue damage caused by a transverse load of the pump tower can be effectively prevented.
