摘　　要：随着深海油气田的快速发展,新兴的浮式生产系统,尤其是半潜式平台,由于具有性能优良、运动响应小、工作水深适用范围广、抗风浪荷载能力强等优点,在工程实际中得到快速的发展。在半潜式平台设计过程中,气隙和斜浪作用下的波浪爬升问题对其安全性能的影响至关重要。通过采用系泊定位状态下的四立柱半潜式平台进行波浪爬升实验,对平台不同位置进行全方位的监测,而后对测量数据进行分析,得出关于海浪对半潜式平台气隙响应的影响和相关规律,为半潜式平台的设计提供参考。With the rapid development of deep water oil and gas fields,the new production system,especially the semi-sub-mersible,has the advantages of good performance,small movement response,wide range of working water depth,resistance of wind and waves and strong load capacity.The influence of air-gap performance and wave climbing under the action of oblique waves on its safety performance is very important in the design of semi-submersible platform.Through the wave climbing experiment of a four-column semi-submersible platform in a mooring position state,omni-directional monitoring is carried out on different positions of the platform.Through the analysis of measured data,the influence of ocean waves on the air gap response of the semi-submersible platform and the related laws are obtained,providing a reference for the design of the semi-submersible platform.
