海上长球首尾双体风电维护船阻力和耐波性能研究

近年来，海上风电场迅猛发展，风电维护船成为迫切需求。借鉴小水线面双体船优良的阻力性能和穿浪双体船优秀的耐波性能，根据中国海上风电场维护船航行的环境和使用特点，选用阻力和耐波性能优良的长球首尾双体船型作为风电场维护船型。在此基础上采用CFD数值仿真计算阻力性能，运用NAPA软件计算耐波性能。从而得到不同条件下较优良的船型，为海上风电维护船的设计提供一定的参考和借鉴。

The Resistance and Seakeeping Analysis of Offshore Maintenance Catamaran in Wind Farm with Big Bulbous Head and Stern

In recent years, with the rapid development of offshore wind farms, maintenance vessels in wind farm become an urgent need. Based on the good resistance performance of SWATH catamaran and the nice seakeeping performance of the wave piercing catamaran, considering the ocean environment and the usage of the maintenance vessels in wind farm, we chose to use the ship form of the catamaran with big bulbous head and stern as the maintenance vessels in wind farm. This ship type has good resistance and seakeeping performance. And on this basis we calculate the resistance performance with the CFD emulation technique and use the NAPA software to calculate the seakeeping performance. Then we obtained the relatively good ship form under different conditions which provides a reference for the designing of the maintenance vessels in the wind farms.
