This Report provides a structured, risk-based framework to evaluate and prioritize different commissioning philosophies applicable to both new-build and repurposed pipelines, across onshore and offshore environments. It draws on industry experience, international standards, and contributions from IOGP Member organizations to enable consistent comparison of commissioning approaches against key criteria such as technical robustness, safety performance, operability, and cost and schedule efficiency. The framework is designed to support informed, scenario-based decision-making rather than prescribe a single preferred methodology.
