桁架式Spar平台气隙响应研究

气隙是深海Spar平台结构设计所需考虑的关键问题之一。Spar平台是浮式平台,在海洋环境荷载的作用下会发生运动,平台结构和波浪还会相互产生影响,因此在计算气隙时须考虑平台运动和波浪运动的耦合作用。利用数值计算方法对桁架式Spar平台气隙响应的影响因素进行了研究。平台垂荡值是影响气隙响应的主要因素;波浪运动对气隙的影响很大,而平台运动对气隙的影响较小。

Study on the air gap response of spar platform

Air gap is one of the most important issue in the design of the deepwater spar platform.Spar platform is a floating platform which moves by the environmental force in the ocean.Because the platform and the wave will influence each other,we must consider the coupling effect of them in the calculation of air gap.We do some research on the air gap response of the spar platform by numerical method.Heave is the key factor to the air gap response,while wave motion is much more important than platform motion for influencing the air gap.
