Integrity management of submarine pipeline systems

Scope and application

This recommended practice gives guidance which can be applied to establish, implement and maintain the Integrity Management System

This recommended practice is applicable to rigid steel pipeline systems, and its associated pipeline components, as defined in DNV-OS-F101 (Sec.1 C343 and C292, and Appendix F). It covers structural and containment failures, and threats that may lead to such failures.

The main focus is on the integrity management process; i.e. the combined process of threat identification, risk assessment, planning, inspection, monitoring, testing, integrity assessment, mitigation, intervention, and repair. Maintenance activities for e.g. topsides controls, chemical systems, and valves which may affect pipeline system integrity are not explicitly covered by this RP.

The integrity management system described herein may also be applicable to rigid risers, however, for details; reference is given to DNV-RP-F206 Riser Integrity Management, which also covers flexible risers.

This document covers (main/trunk) transport lines and in-field lines, which consist of:

- export lines (oil & gas, multi-phase),

- production lines (oil & gas, multi-phase) or

- utility / service lines (gas injection, gas lift, water injection, produced water, chemicals).
