Abstract

The invention provides a multi-point mooring and position-fixing system for floating installation and ship-moving operation and a ship-moving method. The invention establishes the multi-point mooringand position-fixing system by integrating various factors. A mooring line weighing anchor and dropping anchor boat sequentially unties each position-fixing mooring line from a current position to weigh anchor and drops anchor after sailing to a designated position. An offshore wind turbine installation vessel is dragged through the sequential adjustment of the mooring distance of each of the mooring lines so as to ensure the smooth running of installation operation of the offshore wind turbine installation vessel. Through the cooperation of self weighing anchor and dropping anchor operation with the retraction and extension of mooring ropes, the need for transfer and ship-moving operation during the installation operation of pile foundations of an offshore wind farm can be satisfied.

Description

technical field

[0001] The invention relates to the installation of an offshore wind farm, in particular to a method for towing an offshore wind power installation ship based on a multi-point mooring positioning system. Background technique

[0002] In recent years, the newly installed capacity of offshore wind power in the world has maintained an average annual growth rate of about 12%, and the cumulative installed capacity is expected to increase from 8770MW in 2014 to 57980MW in 2024. At present, my country is the fourth largest offshore wind power country in the world, accounting for 8.4% of the global offshore wind power market share. Offshore wind turbine foundations and technologies such as wind turbine installation and maintenance require professional offshore wind power installation ships. At present, the installation of offshore wind turbine foundation mainly has two forms: (1) floating crane + guide frame; (2) self-elevating platform + special pile holder. Throug...
