Hull Form Designing And Optimization Research Of Maintenance Catamaran In Offshore Wind Farms Based On Hydrodynamic

Wind energy is a renewable energy,which is of great importance for promoting in our whole country.In recent years,the development and utilization of wind energy have played an important role in people's livelihood and economic development.In the meanwhile,the popularity of wind power industry is increasing throughout the world.However,the efficiency of the wind farm investment depends on the timely operation and maintenance of the offshore wind turbine.Because wind,wave,flow and tide affect the offshore wind farm,it is necessary to study the performance of wind power operation and maintenance ship to provide safe,economic and efficient sea transportation for operation and maintenance,which is in order to improve the operation efficiency and effectiveness of offshore wind farm.Combine with the use requirement of the offshore wind farms and related material,I analyze the characteristic of the maintenance catamaran in offshore wind farms,to determine the principle dimensions of the catamaran,and using NAPA to do the ship lines designing.Combining with the actual use of the maintenance vessel,we can design the layout of the ship.Based on the impact parameters of NAPA software,by analyzing the main influence parameters of the offshore maintenance vessel for wind farm,using NAPA Basic language to build macro design process and combine with the parametric design concept,the parametric modeling of the whole ship is realized.According to the parametric model,use CFD to establish numerical analysis model and set boundary conditions for the computational model.Based on the ISIGHT,I do research on the principal dimensions of ship form coefficients,hull separation and other parameters of maintenance catamaran in offshore wind farms.Three aspects of the design optimize rapidity,seakeeping and also take performance into account.According to the results of the calculation,use the principle of integration and optimization to choose the vessel type of good rapidity,seakeeping and other performances for offshore wind farms.Optimization research of the performance of maintenance catamaran in offshore wind farms is based on numerical multidisciplinary design optimization method,which is applied to the field of ship design.Research achievement and conclusion obtain in this paper have certain reference value on vessel design and performance optimization.It also has certain value on theory and engineering practice.
