Abstract: Key activities in the integrity management process of pipelines are intelligent pigging inspection planning and integrity status assessment. Considerable cost savings can be realised when utilising Risk Based Inspection (RBI) methodology. For example, RBI techniques generally yield longer inspection intervals compared to time-based inspection, are effective in prioritising pipelines when only limited inspection resources are or can be made available and can give the confidence for safely postponing repair or replacement of damaged pipelines.

Shell has developed and is implementing RBI methodology for pipelines. The Shell Risk Based Inspection (S-RBI) approach has been embedded in the Pipeline Integrity Process loop and integrated with tools for corrosion rate assessment, remaining life assessment and rehabilitation planning, see Figure 1. The MS-Access data management system "PIPE-RBI" has been developed by which the S-RBI methodology and support tools can be applied.
