Floating structure with liquefied gas storage facility and design method thereof

摘要

[PROBLEMS] To secure a place where a cargo handling facility, a superstructure and a large-sized fitting can be newly arranged while reducing the danger caused by high-pressure gas leakage in a fuel gas pipe, and not only LNG but also other gases. A floating structure having a liquefied gas storage facility that can be efficiently transported by intra-regional transportation or short-distance transportation and can be loaded and unloaded at a plurality of ports, and a design method thereof. A floating structure 1A having a liquefied gas storage facility having an engine room 5 behind a cargo compartment R1 of a cargo tank 11 formed of a low-temperature liquefied gas tank, the rear of the cargo compartment R1, and In the state where the cargo equipment room 12 is arranged in part or all of the upper side of the engine room 5, the total loading capacity of the cargo tank 11 is 60,000 m 3 or more and 90,000 m 3 or less, and the cargo tank 11 and the cargo hold 10 are sufficient. In addition, the hull structure has sufficient stability for drought and lateral inclination sufficient for navigation. [Selection] Figure 1
