相对传统的基于时间和状态的检测方法，基于风险检测(RBI)是最近一些年得到快速发展和应用到大型海洋装备的一种新完整性管理检测技术。RBI技术融合数据库管理技术、材料损伤和失效机理分析技术、结构强度有限元技术、裂纹评估断裂力学技术、风险分析和等级评定技术、计算机数字化管理系统等于一体，制定出一套最优化的检测方案和策略，从而实现对高风险结构或设备重点检测，低风险结构或设备放宽检测周期，从而在保障装备结构及设备系统完整性的同时，可有效节约检测成本。本文将比较系统论述如何利用RBI技术实现海上大型油气装备的完整性管理，系统论述如何采用RBI技术对大型深水采油平台的船体、锚系和立管等的结构系统（HullMooringRiser System）进行完整性管理，并着重对基于SN曲线海洋结构疲劳进行了定量风险算例分析。

Compared to traditional timebased and conditionbased inspection methods， Riskbased Inspection (RBI), recently， is a new integrity management inspection technique which has been rapidly developed and applied to large offshore facilities. RBI is an advanced method for developing an optimum inspection plan and strategy which has coupled with techniques of database management， material damage and deterioration mechanism analysis， structural strength FEA， fracture mechanics for crack assessment， risk analysis and ranking， digital computer management system， etc. The RBI approach can guarantee that structures or equipment with higher risk could warrant more focused inspection than those with lower risk， which can effectively reduce inspection cost. This article will systematically discuss how to apply RBI technique for integrity management of large offshore facilities， while focusing on the application of RBI to the hull， mooring and riser systems of large deepwater offshore installations. Besides， a detailed case study on how to perform quantitative risk analysis on SN curve based offshore structures fatigue analysis.
