In view of the specific operational needs of the aquaculture platform, it is of great significance to explore a convenient research method of speedability and develop an economical and efficient power system to reduce the cost of aquaculture, improve the safety of aquaculture and promote the development of industry. The accuracy of CFD hydrostatic resistance calculation is verified by model test comparison, the multi-objective optimization of speedability is carried out based on the CFD technology to obtain the ideal hull low resistance profile, and the reasonable configuration of the power system of aquaculture platform is analyzed from the perspective of power demand, initial construction cost and failure comparison of power system to acquire the power system foundation scheme. The results show that in the case of 9-11 kn and lower Fourier number, the hydrostatic resistance is not obviously reduced by optimizing the line. After the degree of non-uniformity of wake decreases to a certain extent, it will be greatly increased if the resistance is further reduced, which is not conducive to the improvement of the overall speedability. Combined with the actual use demand of mooring condition, the electric propulsion technology is adopted. It can effectively reduce the initial construction investment, reduce the later maintenance and operation costs, and improve the reliability of the power system in the operating condition. According to the configuration requirements of the power system of the aquaculture operation, it is an effective method to study this kind of problem by deducing the speedability of the aquaculture platform.
