The Analytical Solution of Taut-Slack Mooring Line With Tanh-Method

In this paper, the continuous model is introduced and solitary solutions of the nonlinear partial differential equations of taut-slack mooring line are obtained by tanh method, and the plots of results are drawn. The results show that, with the continuous increasing of pretension, the tension curve convert from snap tension to continuous line, until to multi-peaks line. In the process of increasing the pretension, the mooring line transfer from slack to taut, until to breakage, accompanying with tension skip, which is reduced by the system parameters, and different combination of parameters may introduce to different tension in line, and the uncertainty may cause the breakage of mooring system.Copyright © 2012 by ASME
