摘要：
The towing and integrated installation techniques are analyzed for a new submerged tension leg platform of offshore wind turbine. Two sets of towing and sinking techniques are proposed to realize the integrated installation of the submerged tension leg of offshore wind turbine. Numerical simulations are carried out on the wet towing process with and without auxiliary pontoons by using the hydrodynamic software MOSES. Based on the installation process of cable sinking and the sinking process of water injection construction, the motion response of the whole structure of the proposed offshore wind turbine under different working conditions is analyzed. The results show that the better floating stability can be obtained by adding the auxiliary pontoons to the system. The motion response amplitude and the force amplitude of the structure are more sensitive to the wave direction than to the wave height under the cable positioning installation, while the overall change trend is consistent. The heave motion and contact force under the water injecting installation process increase with the rise of the wave, but the variations of the time series are similar. The angular motions will not be considered as the control condition because the maximum values are small. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
