摘　　要：海上吊装操作是平台海上安装作业中的重要一步,深海吊装操作面临着恶劣海况的考验。对于海上吊装操作过程中的多浮体相互干扰运动,采用了时域数值纽马克方法求解,选定JONSWAP风浪谱进行随机海况模拟。重点研究了不同浪向组合对多浮体运动响应的影响,提出安全作业浪向。在安全海况下进行了不同风速影响的研究,提出安全作业的风速范围。在安全作业海况下进行了吊装操作模拟,证实吊装操作能平稳进行,对海上吊装操作安全顺利进行具有重要意义。Offshore sea platform lifting operation is an important step in it＇s installation;it is faced enormous challenge of adverse sea condition.For multi-body interaction during lifting,the time domain numerical Newmark-Beta method was used,and JONSWAP spectrum was selected to simulate the random sea.To focus on multi-body motion response of different combinations of wave direction,a safe operation wave direction was suggested.In safe operation wave direction,wind speed range for safe operation was proposed.In safe sea condition,the hoisting operation was simulated,confirming the smooth operation of the lifting.It is the conduct of great significance to the safe and smooth operation of lifting in the ocean.
