Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to an integrated fuel tank anti-buoyancy structure. Background Technology

[0002] In response to the global strategic goal of low-carbon and zero-carbon development, the use of clean fuels such as LNG in ships is gradually increasing. Among them, Type C freestanding fuel tanks are widely used on ships due to their ease of installation.

[0003] According to the International Safe Regulations for Ships Using Gas or Other Low Flash Point Fuels (IGF CODE), Type C freestanding fuel tanks must be equipped with anti-buoyancy structures. When the fuel tank is damaged and flooded, the anti-buoyancy structures should have sufficient strength to prevent the fuel tank from floating, thereby preventing fuel leakage or the fuel tank from damaging other hull structures.

[0004] Traditional C-type independent fuel tank anti-buoyancy structure, such as Figure 1 As shown. Figure 1 In this design, the anti-buoyancy structure 50, used to prevent the fuel tank 52 from floating, is welded from several steel plates and attached to the main support structure 51 of the hull. As ships become larger, the volume of fuel tanks increases, meaning that the anti-buoyancy structure will have to withstand greater buoyancy when the fuel tank ruptures and floods. In this case, the strength of traditional anti-buoyancy structures will be insufficient.

[0005] Existing technologies have the following drawbacks:

[0006] As ships become larger, fuel tank volumes increase, meaning that when a fuel tank ruptures and floods, the anti-buoyancy structure must withstand greater buoyancy. In this case, the strength of traditional anti-buoyancy structures will be insufficient. Summary of the Invention

[0007] In order to overcome the above-mentioned defects in the existing technology, the present invention provides an integrated fuel tank anti-buoyancy structure.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] An integrated fuel tank anti-buoyancy structure includes a fuel tank disposed within an area enclosed by a hull support member; the fuel tank has a protrusion, and an anti-buoyancy member is disposed above the protrusion to prevent the fuel tank from floating; the hull support member includes an extension extending toward the fuel tank, the extension forming the anti-buoyancy member; the anti-buoyancy member is a component of the hull support member.

[0010] Furthermore, the hull support components include bulkheads and reinforcing members, with the reinforcing members fixed to the outside of the bulkheads.

[0011] Furthermore, the bulkhead includes a lower straight bulkhead and an upper straight bulkhead, with a transversely extending bulkhead between the lower and upper straight bulkheads; the upper and lower straight bulkheads are respectively connected to the two ends of the transversely extending bulkhead.

[0012] Furthermore, the bulkhead also includes an arc-shaped bulkhead located at the upper end of the upper straight bulkhead, with the upper straight bulkhead and the arc-shaped bulkhead being tangent.

[0013] Furthermore, the extension includes a laterally extending bulkhead.

[0014] Furthermore, the extension protrudes from the lower straight bulkhead.

[0015] Furthermore, a buffer component is provided between the extension and the protrusion.

[0016] Furthermore, the lower surface of the laterally extending bulkhead abuts against the cushioning component.

[0017] Furthermore, the buffer component is located on the top of the protrusion.

[0018] Furthermore, the cushioning components are made of wood.

[0019] The beneficial effects of this invention are as follows: In this invention, the anti-buoyancy component is an integral part of the hull support structure. The anti-buoyancy component and other hull support components are integrally formed to create an integrated fuel tank anti-buoyancy structure, thereby improving the strength of the anti-buoyancy structure. This invention can increase the structural strength of the anti-buoyancy device and meet the anti-buoyancy functional requirements of large fuel tanks. Attached Figure Description
