The present invention provides a liquefied hydrogen storage tank for a ship. The liquefied hydrogen storage tank for a ship comprises: a tank unit storing liquefied hydrogen at a cryogenic temperature; and an insulation unit surrounding an outer surface of the tank unit, having a cooling line through which a cooling pipe for cooling the tank unit passes, and including a plurality of insulation panels. The insulation panel includes: a first insulation layer coming in close contact with the tank unit to suppress heat transfer; a second insulation layer disposed outside the first insulation layer and suppressing heat transfer due to heat intrusion inside and outside the tank unit; a third insulation layer disposed outside the second insulation layer and suppressing heat transfer due to heat intrusion inside and outside the tank unit; a first support layer disposed between the second insulation layer and the third insulation layer to support the second insulation layer and the third insulation layer; and a second support layer disposed outside the third insulation layer and fixed to the tank unit to support the insulation panel.

    본 발명은 극저온의 액화수소를 저장하는 탱크부; 및 상기 탱크부의 외부면을 감싸며, 상기 탱크부를 냉각시키기 위한 냉각배관이 지나는 냉각라인을 구비하고, 복수개의 단열패널로 이루어지는 단열부;를 포함하며, 상기 단열패널은, 상기 탱크부에 밀착되어 열전달을 억제시키는 제1단열층; 상기 제1단열층의 외측에 배치되고, 상기 탱크부 내부 및 외부의 열침입에 의한 열전달을 억제시키는 제2단열층; 상기 제2단열층의 외측에 배치되고, 상기 탱크부 내부 및 외부의 열침입에 의한 열전달을 억제시키는 제3단열층; 상기 제2단열층 및 상기 제3단열층 사이에 배치되어 상기 제2단열층 및 상기 제3단열층을 지지하는 제1지지층; 및 상기 제3단열층의 외측에 배치되고, 상기 탱크부에 고박되어 상기 단열패널을 지지하는 제2지지층;을 포함하는 것을 특징으로 하는 선박용 액화수소 저장탱크를 제공한다.
