일반적으로, 종래의 LNGC(액화천연가스운반선)는 액화천연가스에 의한 화물창의 취성파괴를 방지하기 위하여 코퍼댐에 글리콜워터를 공급하는 장치를 사용하였다. 하지만 종래의 글리콜워터 공급 장치는 단순히 글리콜과 퓨어워터를 혼합하는 데에 그쳤다는 점에서 코퍼댐의 자체 온도를 높이지 못하는 문제점이 있었다.In general, a conventional LNGC (Liquefied Natural Gas Carrier) uses an apparatus that supplies glycol water to a cofferdam to prevent brittle fracture of the cargo hold by liquefied natural gas. However, the conventional glycol water supply device merely mixes the glycol and the pure water, and thus has a problem in that it can not raise the temperature of the copper dam itself.
