Ship ballast tank structure and machining method thereof

Abstract

The invention provides a ship ballast tank structure applied to the technical field of ship construction. The invention further relates to a machining method of the ship ballast tank structure. According to the structure, a bilge connecting plate I (6) is arranged at the lower part of a broadside I (3) of the ship ballast tank structure; the broadside I (3) is provided with a broadside I bringing-in section (7) which is vertically arranged; a cabin bottom connecting plate II (8) is arranged at the lower part of a broadside II (4); the broadside II (4) is provided with a broadside II bringing-in section which is vertically arranged; a groove-shaped bulkhead (2) comprises a groove-shaped bulkhead upper part (25) and a groove-shaped bulkhead lower part (26); a transverse groove wall I (10) with a Z-shaped horizontal section is arranged on one side of the groove-shaped bulkhead (2). According to the ship ballast tank structure, a segmented structure of a ship ballast tank is improved, damage to a coating of the ballast tank is reduced during total assembly and carrying, the paint integrity is guaranteed, meanwhile, multi-face operation can be conveniently conducted in the slipway stagewith the cabin integrity as the benchmark, and the construction period of a ship is shortened.

Description

Technical field [0001] The invention belongs to the technical field of ship construction, and more specifically, relates to a ship ballast tank structure. The invention also relates to a method for processing the ship ballast tank structure. Background technique [0002] With the rapid development of the shipbuilding industry and the rapid improvement of trade globalization, the cycle requirements for shipbuilding enterprises have become more stringent and urgent. At the same time, the requirements for the service life of paint are also increasing. Therefore, it is necessary to pay attention to the protection of paint at all times during the design, manufacture, and operation of ships. Basically, all ships built now should meet the requirements of the "Protection Coating Performance Standard" (ie PSPC) for ballast tank coating, avoiding continuous 25M 2 Damage and damage ≤ 2% of the cabin area. Therefore, when the ship construction section is transported after the painting is fi...

AI Technical Summary

Problems solved by technology

For ships without bottom piers, when the general group is loaded, the lower opening of the corrugated bulkhead (sway closing joint) is directly welded to the bottom plate, and both sides of the corrugated bulkhead are welded to the longitudinal wall of the inner hull, resulting in ballast under the inner bottom plate The paint coating of the ballast tank on the outside of the tank and the longitudinal wall of the inner hull is damaged, and the damaged area exceeds the requirements and directly affects the certification qualification and construction period of the PSPC
