Cargo hold watertight transverse partition wall structure

Abstract

The invention provides a cargo hold watertight transverse partition wall structure. A cargo hold is arranged in a ship body, a liquid tank is arranged in the cargo hold, the watertight transverse partition wall structure comprises a watertight transverse partition wall which is arranged in the cargo hold and extends in the width direction of the ship body, and the watertight transverse partition wall comprises an inner support in watertight connection with the outer wall of the liquid tank and an outer support in watertight connection with the inner wall of the cargo hold; the inner support and the outer support are in watertight connection through an elastic sealant; and the n (n > / = 1) watertight transverse partition walls divide the cargo hold into n + 1 independent cabins which are mutually watertight and not connected. Compared with the prior art, the watertight transverse partition wall structure has the advantages that on the premise that the size and the capacity of the cargo hold and the liquid tank are not reduced, the damage water inflow of the cargo hold is reduced, the damage stability of a ship is improved, and then the safety of the ship is increased; and a better stability balance index is achieved while a double-layer shell is not arranged, and the cabin capacity utilization rate is guaranteed while the cabin breaking stability residual capacity of the ship is improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a watertight transverse bulkhead structure of a cargo hold. Background technique [0002] In the process of ship design and use, ensuring stability and safety is the basis of ship design. Only by meeting the ship 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 water ingress, reasonable design schemes and technical preparations need to be given to reduce the risk of ship capsizing. Among the various damage situations of the ship, the most dangerous one is the water ingress due to the damage of the cargo hold. This is because the space in the cargo hold is large, and the amount of water ingress is large when it is damaged, and the ship faces a greater risk of insufficient stability of the damage. [0003] In the existing ship design, methods such as increasing the...

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
