Liquid cargo tank arrangement method of liquefied gas carrier and liquefied gas carrier

A technology of a liquefied gas ship and an arrangement method, which is applied to some cabins in the hull, the hull, and the parts of the ship, can solve the problems of increasing the evaporation rate of the liquid cargo and the weight of the steel structure of the hull, which is not conducive to the design effect of the overall structure of the ship, and achieves weight reduction. , the effect of reducing the number and reducing the evaporation rate

Problems solved by technology

However, the greater the number of cargo tanks, the greater the number of loading and unloading equipment in the cargo tank (one set is required for each cargo tank), the sum of the outer surface area of ​​the cargo tank with the same volume, and the number of transverse partition bulkheads in the cargo tank of the ship. It will increase the evaporation rate of the liquid cargo and the weight of the steel structure of the hull, which is not conducive to the design effect of the overall structure of the ship

Abstract

The invention relates to the technical field of liquefied gas carriers, in particular to a liquid cargo tank arrangement method of a liquefied gas carrier. At least two liquid cargo tanks are arrangedalong the longitudinal direction of the liquefied gas carrier; adjacent liquid cargo tanks are spaced to form a first isolation void cabin; and the extension length of the first isolation void cabinalong the longitudinal direction of the liquefied gas carrier is greater than the maximum longitudinal damage range. The invention further relates to the liquefied gas carrier; at least two liquid cargo tanks are arranged in the longitudinal direction; the first isolation void cabin is formed between every two adjacent liquid cargo tanks at intervals, and the extension length of each first isolation void cabin in the longitudinal direction of the liquefied gas carrier is larger than the maximum longitudinal damage range. Therefore, it can be guaranteed that two adjacent liquid cargo tanks cannot be damaged at the same time under any broadside damage working condition, the stability of the liquefied gas carrier under the broadside damage working condition can meet the standard requirement,and the number of the liquid cargo tanks can be reduced as much as possible within the limited ship length range.

Description

technical field [0001] The invention relates to the technical field of liquefied gas ships, in particular to a liquid cargo tank arrangement method of a liquefied gas ship and a liquefied gas ship. Background technique [0002] According to the requirements of the "International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk" ("IGC Code"), the damage stability calculation of a liquefied gas carrier is carried out according to the deterministic damage rules: figure 1 As shown, when the ship is damaged at the side, there are regulations on the maximum longitudinal damage range Lsd and the maximum transverse damage range Bsd, and the maximum longitudinal damage range Lsd and the maximum transverse damage range Bsd constitute the damage area A. That is to say, assuming that the ship is damaged from the side to the inside of the hull, the area within the damaged area A will be damaged, and the other areas will remain intact; there is no limit to...
