摘要
采用水池模型试验和数值模拟方法,对"蓝鲸"号大型起重船吊装海洋平台上部组块的过程开展运动响应研究,对比分析无吊物和吊物施工时的运动结果,两者吻合较好,讨论在顶浪规则波工况下该复杂耦合系统的运动响应特性。研究结果揭示在波浪中系泊起重吊装组块耦合运动机理,为海洋平台吊装施工作业提供技术支持。
Pool model test and numerical analysis are carried out to study the coupling motion response of the mooring crane vessel " Lanjing" during lift operations.The results of model test and numerical simulation are compared with and without topside in heading regular waves,and the agreement is fairly well.The physiccal mechanism behind the coupling motions of mooring crane vessel in the waves is discussed,which provide technological support for lifting operations.
