不同覆盖物清理状态下海底电缆打捞受力仿真
摘要
Abstract
In this paper,through the analysis of the mechanism of deep and shallow water salvage process of submarine cable,it is determined that the cover has a certain influence on the salvage process.The salvage process model is established by OrcaFlex considering hydrodynamics,and the effects of cover thickness and position on tension and curvature in the process of submarine cable salvage are studied.It is found that when the covering section is salvaged,the cable tension will fluctuate obviously,and the extreme curvature of the cable will increase obviously in the salvage process.With the increase of the thickness of the cover,the extreme curvature of the cable increases gradually,and the tension fluctuation of the cable becomes more obvious.The covering only has an obvious influence on the extreme curvature of the covering section;when the cover at the lifting point is not completely cleaned,the submarine cable is prone to bending failure,and the covering far from the lifting point has little effect on the extreme curvature of the cable along the cable in the salvage process.In actual working conditions,targeted work and protection can be carried out to reduce the workload and improve the salvage efficiency,so as to prevent the cable from secondary damage in the salvage process.关键词
