Description

Technical Field

[0001] The utility model relates to the technical field of offshore operation equipment, in particular to a new offshore boarding trestle. Background Art

[0002] The existing technology for utilizing offshore energy includes using offshore wind turbines for wind power generation and using offshore oil platforms for oil extraction. After operating for a period of time, facilities such as offshore wind turbines and offshore oil platforms need to be maintained or repaired, which requires the transportation of maintenance personnel and materials to the offshore wind turbines or offshore oil platforms. The main method is currently to use small ships to transport personnel, but this method has the following defects:

[0003] When using small ships to transport personnel, the situation at sea is complicated. Sea wind, waves and tides are the key factors that cause the impact. The effect of waves and tides causes the distance between the ship and the offshore fixed structure to change in several directions at any time. When maintenance personnel board / leave the offshore fixed structure, they are affected by the waves, and there will be a relatively large relative movement between the ship and the offshore structure. At the same time, small ships are also affected by waves and tides. Small ships are prone to collide with offshore structures and cause damage to themselves. Large ships are affected by waves and tides and cannot effectively dock at the edge of offshore basic structures, resulting in collisions and damage to offshore structures, which will pose a threat to personnel safety.
