Description

Technical Field

[0001] The present invention relates to the technical field of cryogenic liquefied gas ships or ships using cryogenic liquefied gas fuel, and relates to a sliding saddle for a cryogenic liquefied gas manifold area. Background Art

[0002] For cryogenic liquefied gas ships such as LNG, LPG or liquid hydrogen, or ships using cryogenic liquefied gas fuel, the cryogenic liquefied gas transfer hose is supported by a saddle in the manifold area. Since the saddle is not permanently fixed at the operation position in the manifold area, the current installation process of the saddle is to first lift the saddle to the operation position by a hose hoist before operation, and then fix the saddle. After the operation is completed, the fixing device of the saddle is released, and then the saddle is lifted to the storage position by the hose hoist. This operation process requires a lot of time and manpower. And for some cryogenic liquefied gas fuel ships, the manifold area is arranged in a semi-enclosed area with a structural platform at the top. The saddle cannot be directly transferred to the operation position by hoisting, and relay transfer is required, which is a complex process and has great potential safety hazards. Although for this area, it can be considered to fixedly install the saddle on the outboard-flipping side door, but this method is costly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the current installation workload of the saddle is large, and for the manifold area arranged in a semi-enclosed area, the installation of the saddle is difficult.

[0004] For such ships, a sliding saddle can be considered. It is fixedly stored at the operation position in the manifold area. Before operation, the position of the saddle can keep the hose at a certain distance from the outer hull plate to avoid the influence of the low temperature of the hose on the hull structure. After operation, the saddle slides into the ship's side to avoid exceeding the maximum ship width. The operation process can be briefly summarized as follows: when operation is required, first release the fixing device of the saddle, and then the crew manually slides the saddle a certain distance outboard and fixes the saddle; after the operation is completed, first release the fixing device of the saddle, then slide the saddle into the ship's side, and finally fix the saddle again. This can save operation time, reduce the work of the crew, improve work efficiency, and at the same time solve the problem of saddle arrangement in the semi-enclosed area manifold.

[0005] In order to achieve the above object, the technical solution of the present invention provides a sliding saddle for a cryogenic liquefied gas manifold area, which is arranged above the main deck or the sunken deck, and includes a saddle, a sliding track, a base, a sliding device, a grille platform, a first fixing device, a second fixing device, and a third fixing device;
