摘　　要：Spar平台以其较大的水深适应范围,较好的运动性能和稳定性,在深海油气资源开采中得到广泛的使用。随着技术的进步,各种新型的Spar平台形式不断涌现,其各方面的性能也得到大量的研究。结合前几代Spar平台形式的特点,提出了一种新型的多柱桁架式Spar平台概念,希望通过桁架的使用,保持Spar良好的运动和受力总体性能,同时采用多柱式的硬舱结构,降低建造难度和成本。并对该Spar平台的水动力特性,载荷以及运动响应进行了数值建模计算,分析结果表明,其运动响应较小,水动力性能良好。Compared with other floating structures, the Spar platform has relatively benign motion performance, excellent stability and adaptation to a wide range of water depth, thus applicable to many oil and gas exploitations in deepwater. With the development of offshore technology, many new Spar concepts have been put forward. Based on the former generations of Spar platforms, the present paper brings in a new Spar concept - the Cell-Truss Spar, aiming to keep the attractive motion performance by means of the tress section, while reducing the fabrication difficulty and cost. Numerical simulation was carried out on the Spar concept and its hydrodynamnics were studied.
