Research on stern sinking and resistance performance of catamaran wind power operation and maintenance ship

针对双体风电运维船在航行过程中的尾下沉现象,通过对双体船的尾部抗扭箱进行改型设计生成系列方案。运用数值仿真技术模拟双体风电运维船在静水中的阻力及尾下沉情况,并将数值仿真计算结果与实船值进行对比,以此探索抗扭箱对双体船静水中阻力及尾下沉的影响,为双体风电运维船尾下沉研究提供一定的参考。结果表明:尾抗扭箱能够很好地起到减小双体风电运维船的静水阻力以及尾下沉量的作用,对于双体风电运维船静水阻力的改善效果在2.51%~3.65%,对于尾下沉量的改善效果能达到30%左右。

Aiming at the sinking of the tail of a catamaran wind power operation and maintenance ship in the process of navigating,this paper generates a series of ship type schemes by remodeling the anti-torsion box of the catamaran.Use numerical simulation technology to simulate the resistance and stern sinking of the catamaran wind power operation and maintenance ship in still water,and compare the numerical simulation calculation results with the actual ship value to explore the effect of the anti-torsion box on the catamaran in still water.This provides a certain reference for the research of catamaran wind power operation and maintenance stern sinking.The results show that the stern torsion box can effectively reduce the hydrostatic resistance and stern subsidence of the catamaran wind power operation and maintenance ship,and the improvement effect on the hydrostatic resistance of the catamaran wind power operation and maintenance ship is 2.51%~3.65%.The improvement effect on the amount of tail sinking can reach about 30%.
