In this article, we discuss the effects of touchdown on an inclined seabed of a mooring system consisting of one or two chains joined at the sinker that is subjected to horizontal tension or tension at the suspension point. We modeled the statics of the system using the classical non-extensional catenary theory. For a system without a sinker, we provide an analytical solution for the governing equations, whereas for a system with a sinker, we derive governing equations that can be solved only numerically. Analytical formulae for the calculation of the restoring coefficient of the system are also provided. Numerical examples and a real case of mooring buoy design illustrate the use of the proposed model.

在本文中，我们讨论了触地对倾斜海床的影响，系泊系统由一根或两根链条组成，该链条连接在沉降片处，该沉降片承受水平张力或悬挂点处的张力。我们使用经典的非扩张悬链线理论对系统的静力学进行建模。对于没有沉降片的系统，我们提供了控制方程的解析解，而对于有沉降片的系统，我们推导出只能用数值求解的控制方程。还提供了计算系统恢复系数的解析公式。数值示例和系泊浮标设计的真实案例说明了所提出模型的使用。
