摘　　要：为研究超大型自航自升式风车安装船满载迁移工况下的水动力特性,以"探险"号海上风车安装船为研究对象,采用基于三维势流理论的水动力分析软件Hydro STAR对船体在迁移时不同环境下的六自由度运动响应和典型横截面处的波浪载荷响应曲线进行分析,并结合不规则波谱进行短期预报,得到各浪向作用下运动最大统计值、典型横截面处的垂向剪力和垂向弯矩最大统计值。对比分析出最危险的谱峰周期及波浪载荷随浪向角和横截面纵向位置的变化规律等。该研究可为海上风车船迁移提供技术支撑,对其作业和实际营运具有现实指导意义。In order to investigate the hydrodynamic characteristics of extra large self-propulsion jack-up wind turbine installation vessel under fully transit condition,the vessel ＂MPI ADVENTURE＂is selected as the research object. The following contents are studied by professional software Hydro STAR based on 3D potential flow theory： Response Amplitude Operator（ RAO） of six-dof,wave loads of several typical sections,and the short term prediction with several irregular wave spectrums. The sensitivity analysis of wave period is conducted. The analysis gives that vertical shear force and vertical bending moment property varying with wave angle and section position. The conclusions can provide technological basis for transit condition analysis and give guidance for offshore installation operation and other practical applications.
