Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship technology, in particular to a flat panel frame structure of a tank type bulkhead for a ship. BACKGROUND

[0002] The tank type bulkhead is widely used in the structure of liquid cargo ships such as oil tankers and chemical tankers, and has the advantages of reducing the weight of the structure, facilitating cleaning, and preventing corrosion. However, the tank type bulkhead also has the disadvantages of low strength, rigidity and stability, especially poor pressure bearing capacity in the direction perpendicular to the tank type. In recent years, due to the change of ship owner's requirements and the change of ship purpose, it is not uncommon to see examples of converting the tank type bulkhead into a flat panel frame. At present, the main methods for converting the tank type bulkhead in ship conversion are as follows: 1) directly removing and replacing the original tank type bulkhead, which is the most common and simple method, and has less restrictions on conversion construction. The original tank type bulkhead is directly removed, and a flat panel frame is added at the position of the original tank type bulkhead; 2) directly adding a flat panel frame, which is suitable for large cabins and does not make any changes to the original tank type bulkhead. A flat panel frame is directly added on both sides of the original tank type bulkhead; 3) covering the outer surface of the tank type bulkhead with a flat panel, which covers the surface of the original tank type bulkhead with a flat steel plate, and welds the four corners of the flat panel with the bottom, the side and the deck. The tank type bulkhead is connected by plug welding in some areas.

[0003] In the above prior art, there are certain technical problems and corresponding defects. The main problems and defects are as follows: 1) in method one, firstly, the original tank type bulkhead needs to be removed, which not only increases the engineering quantity of conversion, but also easily causes damage to the original ship structure at the removal and cutting parts; secondly, the replacement and hoisting of the new flat panel frame need to open a large hole on the original ship deck, which increases the technical difficulty and corresponding engineering quantity; 2) in method two, the new flat panel frame is added on both sides of the original tank type bulkhead. On the one hand, in order to support the new flat panel frame bulkhead on the strong rib position and ensure a certain construction space, the new flat panel frame bulkhead will inevitably occupy part of the original ship capacity, thereby reducing the original ship capacity; on the other hand, the hoisting of the new flat panel frame also needs to open a large hole on the original ship deck; 3) in method three, the outer surface of the original tank type bulkhead is covered with a flat panel, which needs to be plug welded in some areas, thereby increasing the welding and process difficulty; at the same time, the bulkhead after the process conversion has poor strength. In the above three methods, the connection between the new flat panel frame bulkhead and the side plate frame structure, the deck plate frame structure and the like has the defects of technical complexity and difficulty.
