中文摘要：
随着海洋油气资源开发逐渐向深海转移,传统的悬链式系泊系统在技术和经济上遇到难以逾越的障碍。作为一种新型的适用于深水和超深水环境的系泊系统,绷紧索系泊系统面临广阔的应用前景。文章对这种新型系泊系统的发展情况进行了介绍,基于有限元数值分析技术,对系泊系统的两个关键特性,即系缆的绷紧-松弛特性以及纤维系缆的动刚度特性进行了分析和处理,通过算例考察了深海平台运动引起的系缆力响应。
英文摘要：
With the offshore exploitation of oil and gas moving gradually to the deep water, the conventional catenary mooring system encounters problems cannot be solved successfully both in economics and techniques. The taut-wire mooring system is a new type of mooring system which is applicable and effective in the deep or uhra-deep water, and hence it faces a wide engi- neering application. The advance of the new type mooring system is introduced firstly in the paper. Then, based on the finite element method, two key characteristics of the mooring system, one is possible variation between taut and slack states of mooring cables and another is dynamic stiffness of fiber cables, are analyzed and treated in the numerical model. The techniques are applied in a numerical example of a deep-water SPAR with taut-wire mooring system. The responses of motion and tension are computed and investigated.
