求解了由两条绳索组成的三分量系泊的悬链线方程，它们连接在一个浮标或沉点上，其中给出了水深和导缆张力。这种配置是深水系泊设备的典型配置，对于系泊系统的初步设计和系泊浮式平台使用中的稳定性测量都需要解决方案。将问题转化为一个8次多项式方程，并用拉盖尔迭代法求解。在没有浮标或沉降器的情况下，方程简化为四次方程，并可用封闭形式求解。线的伸长被证明等同于单位长度重量的小不确定度。该方法在计算上是有效的。(C)2001爱思唯尔科学有限公司。保留所有权利。
Catenary equations are solved for a three component mooring made up of two lines, connected at a point buoy or sinker where water depth and fairlead tension are given. This configuration is typical of deep water moorings and solutions are required for preliminary design of mooring systems and measurement of stability in service of moored floating platforms. The problem is transformed to a single polynomial equation of degree eight and is solved by Laguerre's iteration. Where there is no buoy or sinker the equation reduces to a quartic and can be solved in closed form. Elongation of the lines is shown to be equivalent to small uncertainties in the weights per unit length. The method is computationally efficient. (C) 2001 Elsevier Science Ltd. All rights reserved.
