海洋油气钻采中海洋平台环境载荷分析

Environmental loading analysis of the ocean platform for the offshore oil and gas exploration

随着油气需求量的不断增加,海洋油气勘探开发的力度逐步增大,对海洋平台的使用越来越多。海洋平台作为服役于恶劣境且承受风、波浪、海流和地震等多种载荷作用的结构体,其安全性对油气开采有重要影响。通过分析风载荷、波浪载荷、海流载荷和地震载荷对平台的作用形式,得到平台在不同服役环境下这些载荷作用于平台的动态响应,对海洋平台的结构设计、强度分析及其安全评估具有重要意义。

With the developing of the oil and gas industry,greater efforts have been made in oil exploration and development,and more and more ocean platforms are used.As a structural body that are subjected to kinds of load,such as wind,wave,ocean current and earthquake,safety of the platform is important to the drilling.Dynamic responses of the platform that are subjected to kinds of load in different conditions are obtained by analyzing effects of these loads,which is of great importance to the structural designing,strength analysis and safety assessment of the ocean platform.
