[0002] Floating offshore wind power is an important technical route of offshore wind power, and floating offshore wind farm usually has the characteristics of deep water depth and far from shore. Unlike fixed offshore wind turbine, floating offshore wind turbine is always in motion, so different maintenance methods need to be taken according to specific circumstances for large component replacement. Floating wind turbine maintenance methods are divided into in-situ maintenance and tow-back maintenance. After the damage of some large components of wind turbine, the tower needs to be lowered for maintenance. Since there is no corresponding specification of semi-submersible construction ship in the industry at present, the mainstream way of lowering the tower is still to tow back to the wharf for maintenance. The anchor chain needs to be cut off before towing back to the port for maintenance. The cutting of anchor chain is time-consuming and laborious, and the cut anchor chain cannot be reused, causing waste. SUMMARY
