系泊定位状态下半潜式浮体波浪爬升性能试验研究

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。

Experimental study on wave climbing performance of semi-submersible floating body undermooring position state

With the rapid development of deep water oil and gas fields, the new production system, especially the semi-submersible, 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 iscarried 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
