Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power conductor frame foundation berthing, in particular to a berthing device with replaceable energy-consuming connecting components. Background Art

[0002] The commonly used method at present is to directly weld the mooring device on the main leg column of the jacket to reduce the impact of the ship on the foundation structure. However, the traditional mooring device usually uses Q355C grade steel and is directly connected to the main leg of the jacket platform by welding, with only rubber fenders installed on the outside of the mooring column. This fixed structure has the following shortcomings:

[0003] 1. The mooring column is welded and fixed to the jacket platform through the mooring device, forming a direct force transmission path. Since the yield strength of the steel used in the mooring device and the steel used in the main leg column of the jacket platform is almost the same, it is easy to cause local dents and overall bending of the platform leg in the event of a collision, which seriously threatens the stability of the main structure of the platform;

[0004] 2. The mooring column is welded and fixed to the jacket platform through common devices. When installing, welding must be carried out on land first, and then installed at sea after completion, resulting in low construction efficiency and seriously affecting the overall construction progress of the project. In addition, when the structure of the mooring device is damaged, it is difficult to replace it quickly, and the repair is difficult and the maintenance cost is high;

[0005] 3. Since the surface of the rubber fender outside the bollard is not smooth enough, a large friction force will be generated when the ship collides, which can easily cause damage to the rubber fender and the bollard.

[0006] The document with the publication number CN115198807A discloses an offshore jacket foundation berthing device, including: a berthing column; a connecting tube, one end of which is connected to the berthing column; an inner tube, one end of which is detachably connected to the end of the connecting tube away from the berthing column; an outer tube, which is sleeved on the end of the inner tube away from the connecting tube, and an annular gap is formed in the overlapping area of ​​the outer tube and the inner tube, and the outer tube is detachably connected to the jacket; an elastic body, which is arranged in the annular gap and is used to connect the outer tube and the inner tube. After analysis, the structural form adopted in this public document is not the same as the structure innovated by the utility model. Utility Model Content
