Research on Drag Reduction Optimization of Offshore Wind Power Installation Vessel Based on Approximate Model

The conventional optimization method for drag reduction of offshore wind power installation ships mainly focuses on the optimization of scouring intensity at the bottom. Although the problem of energy consumption has been reduced to a certain extent, the pressure of power load has been increased, which affects the optimization effect of drag reduction. Therefore, an optimization method for drag reduction of offshore wind power installation vessel based on approximate model is designed. Optimize the drag reduction profile parameters of offshore wind power installation ship, and use the cross section area curve instead of the waterline surface curve to constrain the displacement of the wind power installation ship. Based on the approximate model, the drag reduction calculation domain of the wind power installation vessel is established, and the drag reduction conditions are divided to optimize the viscous resistance of the wind power installation vessel and achieve the purpose of drag reduction optimization. The comparison experiment verifies that the optimization effect of the drag reduction optimization method is better and can be applied to real life.
