拉线塔概念设计用于相对较深的沃茨[超过1,000英尺（300米）]。描述了一个模型，模仿的响应由一个单一的自由度（SDOF）。这个简单的模型的属性来自更详细的模型的刚度，质量和流体动力学特性。通过将计算的单自由度响应与多自由度（MDOF）有限元模型的响应进行比较，评估了简单模型代表塔架响应的能力。从详细的有限元系泊系统分析（单个缆绳）计算的响应用于建立单个系泊缆绳的动态和静态特性。在简单系泊中，每条系泊缆由一个等效弹簧表示。使用静态和动态推导的系泊系统性能的整体动态塔响应进行了比较。
The guyed tower concept is designed for use in relatively deep waters [more than 1,000 ft (300 m)]. A model is described that mimics the response by a single degree of freedom (SDOF). The properties of this simple model are derived from stiffness, mass, and hydrodynamic properties of more detailed models. The ability of the simple model to represent the tower response is evaluated by comparing calculated SDOF response with that of multi-degree of freedom (MDOF) finite element models. Calculated responses from detailed finite element mooring system analyses (of an individual line) are used to establish dynamic and static characteristics of an individual mooring line. Each mooring line is represented by an equivalent spring in the simple mooring. Overall dynamic tower responses using statically and dynamically derived mooring system properties are compared.
