PROBLEM TO BE SOLVED: To provide a floating structure with a liquefied gas storage facility that can secure a place capable of newly additionally disposing a handling facility, a mast and large-scale equipment, while reducing a risk due to high-pressure gas leakage of fuel gas piping, can efficiently transport LNG and also multi-gas such as other gas by intra-regional shipping and short-range transport, and is capable of loading and unloading in multiple ports, and a design method therefor.SOLUTION: A floating structure 1A includes a liquefied gas storage facility having an engine room 5 behind a cargo partition R1 of a cargo tank 11 formed of a cryogenic liquid tank. While disposing a cargo equipment room 12 behind the cargo partition R1 and in a portion or all of the upper side of the engine room 5, the total mounting volume of the cargo tank 11 is 60,000 mor more and 90,000 mor less. The cargo tank 11 and a cargo space 10 are provided with sufficient structural strength. Also, a hull structure includes a freeboard sufficient for navigation and the restoration performance to the heeling.SELECTED DRAWING: Figure 1
【課題】燃料ガス配管の高圧ガス漏洩による危険性を軽減しつつ、荷役設備、船楼、大型艤装品を新たに追加配置できる場所を確保でき、LNGのみならず、その他のガス等のマルチガスを、域内輸送や近距離輸送で効率よく輸送でき、かつ、複数の港で積み荷及び揚げ荷が可能な液化ガス貯蔵設備を備えた浮体構造物及びその設計方法を提供する。【解決手段】低温液化ガスタンクで形成される貨物タンク11の貨物区画R1の後方に機関室5を有した液化ガス貯蔵設備を備えた浮体構造物1Aであって、貨物区画R1の後方で、かつ、機関室5の上側の一部または全部に貨物機器室12を配置した状態で、貨物タンク11の合計搭載容積が60,000m3以上90,000m3以下であり、貨物タンク11と貨物倉10の十分な構造強度を有していると共に、船体構造は、航行に十分な乾舷及び横傾斜に対する復原性能を備えている。【選択図】図1
