基于波浪增阻的长球艏球艉双体风电维护船研究

Research of Maintenance Catamaran in Wind Farm with Big Bulbous Head and Stern Based on Wave Added Resistance

根据中国海上风电场维护船的使用要求和航行的环境特点,选取快速性和耐波性良好的长球艏球艉双体船作为风电维护船船型。利用基于CFD的数值仿真方法模拟长球艏球艉双体风电维护船在波浪中的纵摇和升沉运动,计算其波浪增阻。研究球艏球艉长度和片体干扰对长球艏球艉双体船在波浪中阻力性能的影响,为球艏球艉双体船以及风电维护船的船型设计与优化提供参考。

According to the using characteristics and sailing environment of Chinese maintenance ship in wind farm, the ship form of the catamaran with big bulbous head and stern is chosen as the maintenance vessels in wind farm. Using the CFD method, this paper calculates the heave and pitch motion and adds resistance in waves for the maintenance catamaran in wind farm. The effect of bulbous head and stern length and hull interaction on the added resistance of the catamaran with big bulbous head and stern is researched. This paper provides reference for the ship form design and optimization of the catamaran with bulbous head and stern and maintenance ships in wind farm.
