摘要
针对大型海上升压站导管架借助外部浮力下潜吊装过程,采用气囊作为外部浮力,基于水动力分析软件构建浮吊船、半潜运输船和导管架计算模型,开展吊装过程中3种不同状态下船舶垂荡、横摇及纵摇运动频域响应分析,评价运输船下潜对于起重船和运输船本身运动响应幅值算子(RAO)的影响。针对多体系统,建立时域计算模型,开展3种吊装条件下导管架下潜吊装过程动力响应分析,探究导管架下潜吊装过程中起重船、运输船和导管架运动响应变化,分析作业船舶系泊系统的受力情况。基于上述计算研究,评估施工作业过程的安全性和可行性。
For the submerged lifting process of the jacket support for of a large offshore booster station,airbags were used to supply the external buoyancy in the lifting process.Based on the hydrodynamic analysis software,the computational models of a floating crane ship,semi-submersible transport ship and jacket were established.Frequency domain response analysis was carried out for the heave,roll and pitch motions of the ships at three different states during the lifting process.The influence of the semi-submersible transport ship diving on the motion response amplitude operator(RAO)of the crane ship and the semi-submersible transport ship itself was evaluated.For the multi-body system,a time-domain calculation model was established to analyze the dynamic response of the jacket diving and hoisting process under three hoisting conditions.The changes of the motion response of the crane ship,the transport ship and the jacket during the jacket diving and hoisting process were calculated,and the mooring forces of the operating ship were analyzed to evaluate the safety and feasibility of the construction process.
