Ship ballast water chamber structure and ship

Abstract

The invention provides a ship ballast water chamber structure and a ship. The ship ballast water chamber structure provided by the invention comprises a left ballast water chamber, a right ballast water chamber and a separation chamber wall, the left ballast water chamber and the right ballast water chamber are adjacent and symmetrically arranged, and the separation chamber wall is used for separating the left ballast water chamber and the right ballast water chamber; and a communicating valve capable of being opened or closed is arranged on the separation chamber wall, when the communicatingvalve is opened, the left ballast water chamber and the right ballast water chamber are communicated, and when the communicating valve is closed, the left ballast water chamber and the right ballast water chamber are independent of each other. According to the ship ballast water chamber structure and the ship, the stability of the ship can be improved, and the ship overturning risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of ship design and manufacture, and in particular relates to a ship ballast water tank structure and a ship. Background technique [0002] In order to ensure that various types of ships, including ro-ro passenger ships, have a draft that can ensure navigational safety performance and meet the requirements of floating state adjustment on board under various loading conditions, a certain number of ballast water tanks need to be set up to pass through The adjustment of the water volume in the ballast tank realizes the draft and floating state of the ship under various loading conditions. Usually, when the ship is empty, the weight of the ship alone cannot make the ship reach a draft that meets the safety requirements of navigation. At this time, it is necessary to fill a certain amount of ballast water into the ballast tank to increase The overall weight of the ship to ensure that the ship can reach a draft th...

Problems solved by technology

This solution can reduce the free liquid surface when the ballast tank is loaded with ballast water, but when the ballast tank is empty, if a damage accident occurs in the ballast tank on one side, only the ballast tank on the damaged side Flooding, while the undamaged ballast tank on the other side is not flooded, which will cause "asymmetrical flooding" of the ship, causing the ship to tilt to the damaged side, thereby increasing the risk of capsizing

[0005] The method of adding watertight bulkheads to reduce the lateral span of a single ballast tank can reduce the "free liquid surface", but it will inevitably increase the probability of "asymmetric flooding" of the ship; on the contrary, if the ship's bottom The ballast tank is set as a whole, which can reduce the probability of "asymmetric water ingress" when the ship is damaged, but this will increase the "free liquid surface" under the ship's ballast condition

[0006] It can be seen that the traditional ballast tank division and setting method can only choose one of the two issues affecting the stability of the ship: "free liquid surface" and "asymmetric flooding".
