Ballast tank structure with communicating pipeline

Abstract

The invention belongs to the field of ship arrangement in the field of shipbuilding and discloses a ballast tank structure with a communicating pipeline. The ballast tank structure is characterized inthat a top ballast water tank is arranged between a main deck and a hull shell and is adjacent to a cargo hold, a bottom ballast water tank is arranged between the hull shell and the hull bottom andis adjacent to the cargo hold, the top ballast water tank and the bottom ballast water tank are arranged on two sides of a ship in a bilateral symmetry mode, the top ballast water tank and the bottomballast water tank on the same side are connected in a closed mode through a first communicating pipeline, suction ports are formed in the bottom ballast water tanks on two sides and the cargo hold, pressure control valves re arranged in the cargo hold, and the pressure control valve is hermetically connected with the suction port through a second communicating pipeline. The ballast tank structureis advantaged in that due to the design of the ballast tank structure, the main scale requirement of the ship under the same tank capacity is reduced, energy efficiency of the ship is improved, fuelconsumption of the ship is reduced, and operation cost of a ship owner is reduced.

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...
