Abstract

The present invention provides a method for arranging cargo tanks and ballast tanks of a liquefied gas ship. The cabins of the liquefied gas ship at least include: a ballast tank group, and No. 1 to No. 3 cargo tanks arranged in sequence from the bow to the stern; The ballast tank group includes No. 1 to No. 6 ballast tanks arranged in sequence from the bow to the stern; there is a No. 1 cargo tank transverse bulkhead between the No. 1 cargo tank and the No. 2 cargo tank, and the No. 1 ballast tank There is a No. 1 ballast tank transverse bulkhead between the No. 2 ballast tank and the No. 2 ballast tank, and a No. 2 ballast tank transverse bulkhead between the No. 2 ballast tank and the No. 3 ballast tank. The No. 1 cargo hold transverse bulkhead is located between the No. 1 ballast tank transverse bulkhead and the No. 2 ballast tank transverse bulkhead; the No. 1 cargo hold transverse bulkhead and the No. 1 ballast tank transverse bulkhead The distance between the wall and the transverse bulkhead of No. 2 ballast tank is greater than 9.55m and less than 10.75m. The cargo tank and ballast tank layout method of the liquefied gas carrier has high flexibility for loading adjustment and meets the damage stability requirements.

Description

technical field [0001] The invention relates to a liquefied gas ship, in particular to a method for arranging cargo tanks and ballast tanks of a liquefied gas ship. Background technique [0002] Liquefied gas ships are mainly used to transport liquefied petroleum gas (LPG), petrochemical products (ethane, butane, ethylene, vinyl chloride monomer, etc.), chemical gases and liquid ammonia, etc. At present, the world's gas energy consumption and demand for gas chemical raw materials continue to rise. This brings great opportunities for the development of liquefied gas carriers. [0003] Under this international situation, all ship design units have increased their efforts in the research and development of liquefied gas carriers. The design of a liquefied gas carrier includes cabin layout, especially the layout of ballast tanks and cargo tanks. Reasonable cargo tank and ballast tank layout schemes are extremely important for ship R&D and design. Among them, the reduction in ...
