PR186-215102-R01 Subsea Pipeline RBI Benchmarking

There are many standards, recommended practices (RP) and guidelines available for subsea pipe-line integrity management (PIM). In all of these, inspection is a key part of managing the integrity of subsea pipelines. However, detailed coverage of risk-based inspection (RBI) and detailed inspection planning is limited in these standards, RPs and guidelines

optimization of inspection and inspection frequency is generally determined at operator's discretion unless strictly regulated by authorities. Thus, there is a need to identify operator best practices and attempt to define a unified decision-making process to optimize inspection and inspection frequencies. This document:

· Summarizes the most relevant standards, RPs and guidelines with respect to RBI

· Reports the findings from answered questionnaires and interviews with operators, and

· Identifies potential paths forward to reach a unified inspection planning best practice
