摘　　要：为了实现半潜式海洋平台气隙预报,应用边界元数值方法计算平台垂荡运动的频率响应函数,根据线性变换原理计算给定海况下波浪与平台相对位移的谱函数,建立平台在波浪中运动的气隙响应计算程序。通过对Veslefrikk半潜式平台气隙设计参数的校验计算表明,所提供的气隙响应预报数值算法可以为工程设计提供参考依据。In order to investigate the air-gap response of a semi-submersible platform in waves,the computational procedure was developed by use of the boundary element method to determine the vertical motion frequency response of the platform and of the linear transformation approach to obtain the parameters of the relative displacement spectrum from the wave spectrum under a certain sea-state.A comparison calculation of air-gap for Veslefrikk semi-submersible platform was carried out between design value and numerical prediction values based on this procedure.It is concluded that this procedure can be applied to engineering design practice.
