Use method of ship residual stability improvement system

Abstract

The invention provides a use method of a ship residual stability improvement system. The method comprises the steps that a first suction port arranged in a ballast tank and a second suction port arranged in a cargo hold are arranged, wherein the first suction port and the second suction port are connected through a valve, the valve is connected to a relay integrator, and the relay integrator is connected to power distribution control equipment and display control equipment; a liquid level sensor connected with the relay integrator is arranged in the cargo hold; when the relay integrator receives the control commands of the power distribution control equipment and the display control equipment at the same time, the relay integrator sends the control command of the display control equipment; and when the cargo hold is damaged and water enters, the valve is opened, the cargo hold communicates with the ballast tank, the ship overturning risk is reduced, then the valve is closed, a ballast pump is opened, the water volume of the ballast tank is adjusted, and the ship stability is further improved. As the command of the display control equipment is prior to the command of the power distribution control equipment, once the ship encounters pirates and the cargo hold is damaged simultaneously, the system can be controlled through the display control equipment to prevent the ship from overturning.

Description

technical field [0001] The invention belongs to the technical field of ship arrangement, and in particular relates to a method for using a ship residual stability improvement system. Background technique [0002] In the process of ship design and use, stability and safety are the basis of ship design. Only when the stability of the ship is satisfied can the safety of the crew and cargo be guaranteed. Among them, damage stability is the focus of ship design. For possible ship damage and flooding, reasonable design schemes and technical preparations are required to reduce the risk of ship capsizing. As for the cargo hold, the most dangerous of all kinds of damage to the ship is the damage and water ingress of the cargo hold. This is because the cargo hold has a large space. Once damaged, a large amount of water will enter. The easier it is to overturn. [0003] In the existing ship design technology, to improve the damage stability of ship cargo tanks, methods such as enlarg...

Problems solved by technology

[0005] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a method for using a ship residual stability improvement system to solve the problem of low utilization of cargo tank capacity in the existing ballast tank design, and at the same time, solve the problem of The existing ballast tank connection can only be controlled through the bridge, which leads to the problem that the connection between the ballast tank and the cargo tank cannot be controlled when the ship encounters pirates, resulting in the capsizing of the ship
