本文以1艘船长为170 m的超大型多功能海洋工程双体船为研究对象，基于三维势流理论，对超大型双体船满载状态下匀速航行中的运动响应进行预报，包括在不规则波中的横摇、纵摇、垂荡响应。对船体所受波浪载荷进行短期预报，分析波浪载荷各分量沿船长和船宽方向的分布与变化规律，得到连接桥各纵截面上的波浪诱导载荷的统计值。本文的研究方法为超大型双体船运动响应及波浪载荷研究提供参考，研究结果为超大型双体船结构强度设计优化提供了重要参考依据。
In this paper, a super-large multi-purpose marine engineering catamaran with a length of 170 m is taken as the research object. Based on the three-dimensional potential flow theory, the motion response of a super-large catamaran in a uniform speed under full load is predicted, including roll, pitch, and sway response in irregular waves. The short-term prediction of the wave loads on the hull is carried out. The distribution and variation of the wave loads along the length and width of the ship are analyzed. The statistical values of the wave induced loads on the longitudinal sections of the catamaran bridge are obtained. The research method of this paper provides reference for the research of motion response and wave loads of super large catamaran, and the results also provide an important reference for the structural strength optimization of super large catamaran.
