大风浪中船舶航向优选方法探讨

A Discussion on the Method of Selecting the Course of Ship in Heavy Waves

依据船舶耐波性理论计算结果,运用灰色关联综合评估理论对大风浪中船舶耐波性进行了综合评估,然后根据评估结果确定船舶在波浪中以某一航速航行时的优选航向,并通过实例应用与分析表明,使用该方法能为船舶安全航行提供科学指导。

This paper adopts the theory of gray relational inte-evaluation to evaluate the seaworthiness of ships in waves by the computational results of seaworthiness, then puts forward a method of selecting the course of ship on the basis of the evaluating results; finally indicates that adopting this method can provide an affective guidance in operating ship by means of an application example.
