A new risk-based inspection methodology for offshore floating structures

The Risk-Based Inspection (RBI) programme is a part of the overall Asset Integrity Management (AIM). The RBI programme offers benefits such as providing a rational basis for inspection plans and efficient tools for updating those plans. The ultimate goal of the RBI programme, coupled with a more generic approach to asset integrity management, is to verify the integrity of the facility and its fitness for service. The present study attempts to address a step by step approach which can be followed for RBI planning inspection. Guidelines regarding the various steps of the RBI process are also provided in order to assist in preparing and maintaining the RBI programme. An advanced tool for semi-quantitative risk assessment of offshore floating structures is developed, where the user guide is presented.
