The present invention relates to a glycol water heater for preventing brittle fracture of liquefied natural gas carrier (LNGC) cargo holds, and more specifically, to a glycol water heater for preventing brittle fracture of LNGC cargo holds, which prevents brittle fracture due to liquefied natural gas by heating glycol water to increase a temperature of cofferdams provided between cargo holds. The glycol water heater for preventing brittle fracture of LNGC cargo holds comprises: a plurality of cargo holds in which gas is stored; cofferdams which are provided between the cargo holds and heated by glycol water; a glycol water heater which is connected to the cofferdams to heat cold glycol water discharged from the cofferdams and transfers the heated glycol water to the cofferdams again; a temperature sensor for measuring a temperature of the cofferdams; and a control unit for operating the glycol water heater. If a temperature of the cofferdams measured by the temperature sensor is less than or equal to a temperature set in the control unit, the glycol water heater is activated, and if the temperature is equal to or more than the set temperature, the glycol water heater is deactivated. According to one embodiment of the present invention, by installing a glycol water heater capable of generating glycol water of a high temperature, it is possible to prevent brittle fracture of cargo holds and cofferdams.

    본 발명은 LNGC(액화천연가스운반선) 화물창 취성파괴 방지용 글리콜워터히터에 관한 것으로, 글리콜워터를 가열하여 화물창의 사이사이에 마련되는 코퍼댐의 온도를 높임으로써, 액화천연가스에 의한 취성파괴가 방지되는 LNGC 화물창 취성파괴 방지용 글리콜워터히터에 관한 것이다. 본 발명에 따른 LNGC 화물창 취성파괴 방지용 글리콜워터히터는, 가스가 저장되는 복수개의 화물창; 상기 복수개의 화물창의 사이사이에 마련되고, 글리콜워터에 의하여 가열되는 코퍼댐; 상기 코퍼댐과 연결되어, 상기 코퍼댐으로부터 배출되는 차가워진 글리콜워터를 가열시키고, 상기 가열된 글리콜워터를 상기 코퍼댐으로 다시 전달하는 글리콜워터히터; 상기 코퍼댐의 온도를 측정하는 온도센서; 및 상기 글리콜워터히터를 가동시키는 제어부;를 포함하고, 상기 온도센서에 의하여 측정된 상기 코퍼댐의 온도가 상기 제어부에서 설정된 온도 이하면 상기 글리콜워터히터를 가동시키고, 설정된 온도 이상이면 상기 글리콜워터히터를 가동 해제하는 것을 특징으로 한다. 본 발명의 일실시예에 따르면 고온의 글리콜워터를 생산할 수 있는 글리콜워터히터를 설치함으로써, 화물창 및 코퍼댐의 취성파괴를 방지할 수 있는 LNGC 화물창 취성파괴 방지용 글리콜워터히터가 제공된다.
