Problems solved by technology

However, in the existing technology, the movement amplitude of the floating equipment is blindly limited mainly by experience, the selection of super-sized mooring lines and the simple consideration of the kinetic energy of the floating equipment. Poor performance, unable to meet the requirements for the movement amplitude of the semi-submersible platform during the fan installation process.

Abstract

The invention discloses a semi-submerged platform motion amplitude control method of a floating fan based on wharf mooring, and the method comprises the steps: carrying out the analog simulation and statistical analysis of a plurality of preset mooring schemes, and obtaining the influence of different wave periods and different surge directions on the motion data of a semi-submerged platform after mooring; and an optimal mooring scheme meeting the motion amplitude range of the target semi-submerged platform is obtained, so that the motion amplitude formed by the semi-submerged platform of the floating fan under the influence of tide when berthing at a wharf can be effectively reduced through the obtained optimal mooring scheme, and the precision and reliability of motion amplitude control of the semi-submerged platform are improved. The problem that connection and hole alignment are difficult in the fan installation process due to the too large motion amplitude is effectively solved.

Description

technical field [0001] The invention relates to motion amplitude control of an offshore semi-submersible platform moored at a wharf, in particular to a movement amplitude control method during installation of a fan when a floating wind power semi-submersible platform is moored at a wharf. Background technique [0002] At present, domestic floating wind power equipment is still in the initial stage of prototype project installation. For floating semi-submersible platforms above 5MW level, after installing fans, towers and ballast, the entire equipment weighs more than 10,000 tons, which is a load-bearing weight that cannot be met by most domestic terminals. Therefore, the semi-submersible platform must float in the water to complete the installation of the wind turbine. Due to the influence of tidal surges, the floating semi-submersible platform has been in a state of ups and downs and cannot stand still during the entire installation process of the fan. The more obvious, a...
