The invention discloses a method for adjusting the wet weight of a mooring cable and the mooring cable, belongs to the technical field of ocean engineering, and aims to solve the problem that the rigidity of the mooring cable is reduced due to the sag effect generated by the influence of the dead weight in water. Wet weight adjustment of the mooring rope is achieved by changing the space proportion or the average density of the density adjusting body, when the mooring rope is adjusted to be zero in wet weight, the mooring rope can be straightened under the action of small tensile force in water, the sag effect cannot be generated, reduction of the axial rigidity is avoided, the bearing efficiency of an original mooring rope is reserved, and the service life of the mooring rope is prolonged. In addition, the zero-wet-weight mooring rope is convenient to install in water due to the fact that the mooring rope is not influenced by dead weight, meanwhile, for the floating body platform in a deep water area, the influence of the dead weight of the mooring rope on the floating body platform is zero, consideration of buoyancy design of the floating body platform on the dead weight of the mooring rope is reduced, and the buoyancy design of the floating body platform is facilitated.
本发明公开了一种系泊索湿重调节方法及系泊索,属于海洋工程技术领域,以解决系泊索在水中也会因为自重的影响,产生垂度效应,导致刚度折减的问题,该专利通过沿着系泊索的核心受力体设置密度调节体,通过改变密度调节体的空间占比或平均密度实现系泊索的湿重调节,当系泊索调节至零湿重时,在水中很小的拉力作用下系泊索就会拉直,不会产生垂度效应,避免了轴向刚度的折减,保留了原有系泊索的承载效率,另外零湿重的系泊索由于没有自重的影响,便于水中安装,同时对于深水区域浮体平台,系泊索自重对浮体平台产生的影响为零,减轻了浮体平台浮力设计对系泊索自重的考虑,有利于浮体平台的浮力设计。
