Technical Field

[0001] The invention relates to wind power operation and maintenance equipment, in particular to a lifting type wave compensation trestle. Background Art

[0002] When operating at sea, offshore supply ships are affected by wind, waves and tides and shake significantly. When serving offshore wind power and fixed platforms, offshore supply ships are always in a state of heaving and shaking, which brings great risks to offshore operations and transfer personnel. The safe and stable docking of supply ships with platforms is a very important safeguard to ensure the safety of offshore operations and transfer personnel.

[0003] In the prior art, active wave compensation can be performed by docking a pier with wave compensation. However, due to the large height difference between the supply ship and the offshore wind power and fixed platform, the wave compensation pier can only increase the pitch angle of the pier for docking. There is still a great danger for passengers walking on the pier with a large slope, especially in rainy and snowy weather. In addition, the wave compensation process requires frequent angle adjustments, the operation is complicated, and the docking efficiency is low.

[0004] It can be seen that the existing technology has the problem of low efficiency and high safety risks in docking the pier with offshore floating bodies and fixed platforms. Summary of the invention
