| With the continuous development of new energy in the world,wind power,as an important field of renewable energy,has become an important concern of various countries in the world.The development of offshore wind power has great advantages,such as the rich offshore resources and the use of no land.It can be developed on a large scale,and the efficiency of power generation far exceeds that of land,but the efficiency of repair and maintenance of offshore wind turbines has a great impact on the quality and investment efficiency of wind power generation.Because wind power must be built 10-40 In order to achieve the high efficiency of wind power generation,and the characteristics of high wind and waves on the sea,the structure and hydrodynamic performance of wind power operation and maintenance vessels must meet higher requirements,so as to ensure the safety of maintenance personnel and improve the offshore The efficiency and quality of wind farm power generation.Therefore,this paper studies the key technologies of the overall design of a double-hull aluminum alloy wind power operation and maintenance ship.The main contents of the study are as follows:(1)The hydrostatic resistance test of the catamaran wind power operation and maintenance ship was carried out and the numerical simulation calculation of the catamaran wind power operation and maintenance ship was carried out based on the CFD hydrodynamic performance software STAR-CCM+.Use STAR-CCM+hydrodynamic software to establish a numerical analysis model for the catamaran,and then compare and analyze the simulation and test values of the catamaran wind power operation and maintenance ship in still water;by setting different pieces for the catamaran wind power operation and maintenance ship Spacing,to explore the effect of different body spacings on the resistance and motion response of the catamaran.(2)The stress and strain analysis of the full-hull and local strength of the catamaran wind power operation and maintenance ship was carried out,and the influence of different sheet spacing on the strength of the catamaran wind power operation and maintenance ship was explored.According to the unique characteristics of the catamaran,the finite element software MSC.Patran/Nastran was used to perform finite element analysis on the strength of the transverse and longitudinal frames of the catamaran wind power operation and maintenance ship;Carry out calculations,and then conduct a comprehensive comparative analysis with the resistance and motion responses at different sheet spacings,and seek their laws;adjust and analyze the schemes for the strength of the catamaran connection bridge.(3)Numerical simulation and analysis of the effect of wave compensation on the three-degree-of-freedom wave compensation platform of the catamaran wind power operation and maintenance vessel.Due to the complicated sea conditions at sea,the maintenance work and safe transportation of personnel for the double-hull wind power operation and maintenance ship at sea are also very important.Therefore,it is necessary to study and analyze the hull boarding device.In this paper,through the principle overview of the designed three-degree-of-freedom wave compensation platform device,and then the kinematics analysis of the platform,it is concluded that the three-degree-of-freedom wave compensation platform movement in the wave can be used to simulate the motion of the platform using the superposition of sine and cosine functions Then,a three-degree-of-freedom wave compensation platform model was established for simulation calculation,and the displacement,velocity and acceleration of the three-degree-of-freedom motion of the platform were simulated,and the three-degree of freedom wave compensation platform was proved by calculation.The compensation effect confirmed its feasibility.In this paper,some conclusions and methods obtained by studying the key technologies of the overall design of offshore catamaran wind power operation and maintenance vessels provide help and reference for the overall design of related wind power operation and maintenance vessels. |
