Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shipbuilding, and more particularly to a ship assembly type bulwark device. BACKGROUND

[0002] When a ship sails in a storm, a marine engineering structure is moored in a certain sea area, and sea waves are easy to rush onto the deck. The bulwark is arranged on the open deck and is used to prevent sea waves from rushing onto the deck, protect the safety of personnel, equipment and goods, and ensure the safety of crew and passengers when the ship swings. Fixed bulwarks are often arranged in the initial design of a ship and a marine structure, and it is often found that there is a large wave in the ship during part of the operation window period after reaching the operation sea area, and the low height of the bulwark leads to the fact that the bulwark position cannot be operated and work is carried out, which brings great risks.

[0003] With the diversification and large-scale of transportation of marine structures, the ship with a full deck often transports goods of an ultra-long size, and it is required that the bulwark be conveniently disassembled or changed in shape to meet the operation requirements.

[0004] The conventional design of the disassembled bulwark structure is to make an independent part on the basis of the traditional plate beam combination form, and the lower end is connected to the deck in the form of welding or bolt connection, and the upper end cannot be adjusted in height with the lower end, and the following disadvantages exist.

[0005] 1) Since the bulwark is a whole bulwark, a special space is needed to store the disassembled bulwark after disassembly, which causes waste of space;

[0006] 2) The traditional bulwark is a steel plate welded bulwark, and after the design shape is determined, the height cannot be adjusted in the later period. If the height needs to be adjusted, the whole bulwark needs to be cut off, redesigned, built and welded to the original ship. The whole cutting of the bulwark will cause damage to the main structure of the ship, and will affect a series of problems such as painting and construction, and often needs to be returned to the shipyard for repair, and the new bulwark needs to be redesigned and built, and the time cost and the cost of the modification project are often large.
