Flexible Pipe Integrity Management

Unbonded flexible pipe remains a vital technology, with use expanding into more demanding applications despite its maturity since the 1970s. Manufacturers continue R&D to meet evolving needs, although a few new failure modes have emerged.

This latest project and guidance provide key datasets and insights, including:

• A population database covering over 22,500 pipe sections and 20,500+ km of flexible pipe

• Nearly 900 documented damage/degradation events spanning ~50 years, most (~80%) not resulting in loss of containment—demonstrating the pipes’ robustness even under abnormal conditions

• Good practice guidance on inspection, monitoring, maintenance, and repair to support effective integrity management

• Lessons learned across all life cycle stages and a summary of current industry technology developments

• This guidance is not a regulatory or minimum requirement document. It promotes risk-based integrity management—good practice should be applied as appropriate.

• Recommendations are based on consensus from the JIP steering committee, though not all members may agree on every point.
