There are three primary types of spars; classic, truss, and cell: A classic spar consists of a tall-height, cylindrical hull, with tanks for heavy ballast located at the bottom of the cylinder. A truss spar comprises three parts, a short-height, large-diameter cylindrical hull, atop a truss structure, atop tanks for heavy ballast.

2022年7月29日 · A spar is a floating platform primarily utilized in intense waters. It is named after logs used as buoys in shipping and moored vertically. Engineers developed spar buoy foundations as an alternative to traditional floating platforms.

2019年12月4日 · Spar platforms currently in service and under construction in the world can be divided into three types, which are Classic Spar, Truss Spar, and Cell Spar. Classic Spar – First Generation. The main body of the Classic Spar is a cylinder suspended vertically in the water. The overall diameter is large. The length is generally between 20 m and ...

为研究经典式Spar平台的涡激运动和驰振特性,开展了平台在系泊状态下的水池模型试验,分析不同流速作用下Spar平台的横荡运动特性,并通过对比仅流、仅波浪与波流耦合工况试验结果,分析波流耦合作用对Spar平台涡激运动和驰振运动性能的影响.结果表明:高折合 ...

Spar平台由于其经济性和稳定性优于其他浮式平台,在经过短暂的二十几年来的发展中,已经开发出三代类型，分别为经典式(Classic Spar)、桁架式(Truss Spar)和分简集束式(Cell Spar)。

Three spar concepts are in use today: the classic spar, the truss spar, and the cell spar. Although the technology and analysis methods are considered mature, technical challenges remain, including understanding and suppressing vortex-induced motion and improving survivability in category 4 and 5 hurricanes.

该文基于Lyapunov指数研究经典式Spar平台主体垂荡-纵摇非线性耦合的混沌运动。 建立了规则波浪中平台主体垂荡-纵摇耦合非线性微分方程，以经典式Spar平台为例，数值计算了响应的最大Lyapunov指数谱及分岔图，在波高和波浪频率构成的平面上，计算了平台不稳定纵摇运动的参数域。 结果表明，平台运动形式对波浪激励频率非常敏感，随着波浪频率的改变，Spar平台发生1/2亚谐运动、概周期运动，当波浪频率接近垂荡固有频率时，发生混沌运动。

The study offers precise modelling of spar platforms for ultra-deepwater operations and improves technical parameters, economic aspects and other criteria.

目前对于Spar平台非线性运动稳定性与耦合动力响应方面的研究已成为海洋工程界关注的焦点。 本文依据非线性动力学理论,研究经典式Spar平台主体运动的非线性稳定性问题;采用数值模拟方法,计算在规则波浪下主体-系泊系统的耦合动力响应。

本文介绍了不同类型的Spar平台，包括桁架式Spar、多立柱式Spar和MinDoc Spar。 这些平台在结构、建造难度、经济性和性能方面各有特点。 桁架式Spar使用较少的钢材，降低了建造和运输难度，同时通过阻尼板减小垂荡运动。
