Semi-enclosed bulkhead structure of cargo hold

Abstract

The invention provides a semi-closed bulkhead structure of a cargo hold, a cargo hold is arranged in the hull, and a liquid tank is arranged in the cargo hold. A bulkhead extending in the width direction, the bulkhead includes an inner support that is watertightly connected to the outer wall of the liquid tank, and an outer support that is watertightly connected to the inner wall of the cargo hold, the inner support and the outer support are mutually The two are watertightly connected by an elastic sealant; the highest point of the bulkhead is lower than the top of the cargo hold, the cavities in the cargo hold above the bulkhead are connected with each other, and the height is lower than The cavity of the bulkhead is divided by n (n≥1) of the bulkheads into n+1 parts that are not connected to each other in watertight. The advantages of the present invention are: on the premise of not reducing the size and capacity of the cargo hold and the liquid tank, the damaged water inflow of the cargo hold is reduced, the damage stability of the ship is improved, and the safety of the ship is further improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a semi-closed bulkhead structure of a cargo hold. Background technique [0002] During the design and use of a ship, ensuring stability and safety is the basis of ship design. Only by meeting the ship's stability requirements can the safety of crew and cargo be guaranteed. Among them, damage stability is a key concern in ship design. For possible ship damage and flooding, reasonable design plans and technical preparations need to be given to reduce the risk of ship capsizing. Among the various damage situations of ships, the most dangerous is the cargo hold damaged and flooded. This is due to the large space in the cargo hold and the large amount of water entering when it is damaged. The ship faces a greater risk of damage and insufficient stability. [0003] In the existing ship design, methods such as increasing the ballast tank, increasing the isolation void, increasing ...

AI Technical Summary

Problems solved by technology

Among the various damage situations of the ship, the most dangerous is the damage of the cargo hold and water ingress. This is due to the large space in the cargo hold, and the large amount of water ingress when it is damaged, and the ship is facing a greater risk of insufficient stability of the damage.

[0003] In the existing ship design, methods such as increasing the ballast tank, increasing the cofferdam, increasing the double hull of the cargo hold, increasing the freeboard draft, and increasing the reserve buoyancy are usually used to improve the damage stability of the ship. It will reduce the capacity utilization rate of the cargo hold and increase the fuel consumption of the ship, resulting in poor energy efficiency of the ship
