Title: FLOATING BODY STRUCTURE EQUIPPED WITH LIQUIFIED GAS STORAGE FACILITY, AND DESIGN METHOD THEREFOR
Abstract:
A floating body structure 1A to 1E equipped with a liquefied gas storage facility, the floating body structure having a machinery room 5 at the rear of a cargo zone R1 having cargo tanks 11 formed from low-temperature liquefied gas tanks. This floating body structure is configured so that, with a cargo equipment room 12 disposed on all or part of the upper side of the machinery room 5 at the rear of the cargo zone R1, the total installation volume for the cargo tanks 11 is in the range of 60000-90000 m3. The cargo tanks 11 and cargo holds 10 have sufficient structural strength. The hull structure is equipped with freeboard and heel stability sufficient for navigation. Thus, the danger of leakage of high-pressure gas from a fuel gas pipe is reduced, and the space for arranging additional loading and unloading facilities, superstructures, and large fittings is ensured. Furthermore, multi gas, such as other gases, as well as LNG, is efficiently transported by regional transportation or short-distance transportation.
