By collecting relevant data on the design,construction,use,maintenance during operation,media testing and container inspection of containers in previous years,a risk based inspection(RBI)technique was used to evaluate 11 pressure vessels in a Bohai oilfield that exceeded their design lifespan.The damage modes and corrosion mechanisms present in the container were analyzed,and the corresponding failure modes were identified.A professional software(DNV Offshore)was used to establish a database of the container and analyze and calculate it.The risk rating of each container was completed,and targeted detection strategies were developed based on the risk level situation.
