【摘要】 考虑海底地形的变化、系缆的拉伸形变及海流力等因素,研究了深海平台系缆形状和张力分析方法采用集中质量法,得到系缆方程组,采用牛顿法求解该非线性系缆方程组,建立系缆形状和张力的计算方法。计算了平坦海底和海底地形凹凸变化时水深1 018 m情况下的系缆形状、系泊张力和浮体平衡位置。计算结果表明,海底地形对于深海系泊系统张力影响较大,而计算系缆形状和张力、系泊浮体的运动时,需要考虑海底地形的影响。更多还原

【Abstract】 The this paper studies the methods of analyzing cable configuration and tension for platforms in deep sea.Considering hypsography on seabed,cable extension and current force,and using the lumped massed method,the equations of cable are formulated,and cable configuration and tension are obtained by using Newton method to solve the equations.The mooring system in 1018m depth is analyzed.The study shows that hypsography on seabed is an important factor influencing the mooring system in deep sea and should not be neglected.更多还原
