| 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。

| Abstract: | 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 sa... |
