Problems solved by technology
The mooring chain is connected to the mooring eye plate of the suction anchor through shackles. In actual layout, the mooring eye plate needs to be arranged facing the fan, and the azimuth angle deviation between the mooring eye plate and the fan is required to be less than 0.5°, while the suction anchor During the installation process, it will be shaken by the influence of waves, so that the azimuth angle of the suction anchor and the fan will deviate after entering the mud, and it is impossible to accurately control the azimuth angle of the installation

Abstract
The invention belongs to the technical field of suction anchor installation, and discloses a suction anchor azimuth angle adjusting method. The method mainly comprises the following steps: hoisting a suction anchor by using hoisting equipment and slowly putting the suction anchor into a water surface, wherein the suction anchor partially sinks to a position below a mud surface under the gravity of the suction anchor; the adjusting platform is close to the suction anchor, an anchor gear is arranged on the adjusting platform, and a retractable traction piece on the anchor gear is connected with the suction anchor; the anchor gear is controlled to recycle the traction piece, so that the traction piece pulls the suction anchor in the tangential direction of the suction anchor; the suction anchor rotates around the axial direction of the suction anchor under the traction effect of the traction piece so as to adjust the azimuth angle of the suction anchor relative to the center of the draught fan. According to the method for adjusting the azimuth angle of the suction anchor, the azimuth angle of the suction anchor relative to the draught fan can be rapidly and reliably adjusted, and it is guaranteed that the suction anchor can be more accurately and reliably installed.
Description
technical field [0001] The invention relates to the technical field of suction anchor installation, in particular to a method for adjusting the azimuth angle of a suction anchor. Background technique [0002] With the continuous maturity and development of related technologies in the field of wind power, offshore wind power facilities have entered a period of rapid development, among which floating wind turbines have received extensive attention. As an important offshore fixed component, the suction anchor is an indispensable part of the offshore wind turbine assembly. The offshore wind turbine is connected with the suction anchor through the mooring chain, and the suction anchor is placed in the sea and firmly fixed to the seabed under the action of its own suction, thus providing a reliable fixing effect for the offshore wind turbine. The mooring chain is connected to the mooring eye plate of the suction anchor through shackles. In the actual arrangement, the mooring eye ...
