Abstract

The invention belongs to a ballast tank structure with connecting pipelines in the field of ship layout in the field of shipbuilding. The water tanks are arranged between the hull shell and the bottom of the ship, adjacent to the cargo tanks; the top ballast tanks and the bottom ballast tanks are symmetrically arranged on both sides of the ship; the top ballast tanks and the bottom ballast tanks on the same side The tanks are airtightly connected through the first communication pipeline, suction ports are arranged in the bottom ballast water tanks and cargo tanks on both sides, and pressure control valves are arranged in the cargo tanks; the pressure control valves and suction ports are sealed through the second communication pipeline connected. The design of the ballast tank structure reduces the main dimension requirements of the ship with the same tank capacity, improves the energy efficiency of the ship, reduces the fuel consumption of the ship, and reduces the operating cost of the ship owner.

Description

technical field [0001] The invention relates to the field of ship layout in the field of ship manufacturing, and more specifically relates to a ballast tank structure. Background technique [0002] At present, the world's gas energy consumption and demand for gas chemical raw materials continue to rise, which brings great opportunities for the development of liquefied gas carriers (referred to as liquefied gas carriers). Under this international situation, all ship design units have increased their efforts in the research and development of liquefied gas carriers. [0003] In the process of designing and producing liquefied gas carriers, the damage stability and safety of the cargo hold area is the top priority. In order to improve the damage stability of ships, the double-hull design scheme of the ballast tank in the cargo hold area is often adopted, and the double-hull width in the usual double-hull arrangement of the ballast tank needs to be greater than one-fifth of the...
