Managing Internal Flowline Integrity

Source: 1/28/2022, Location: Europe

A study carried out by Maintech AS for the Petroleum Safety Authority Norway (PSA) has produced a reference work on internal integrity management of rigid flowlines to help avoid hydrocarbon leaks.

The study covers the following topics:
- advances in internal integrity management over the past 30 years
- threats to internal integrity
- monitoring equipment
- corrosion models
- predictive techniques
- inspection methods
- integrity management
- how to ensure robust integrity management given what is known and unknown.

The study forms part of the PSA’s sectoral work directed at integrity management of flowlines and subsea facilities. The following studies commissioned by the PSA are also relevant.

Relevant studies
- Subsea Integrity Management – Maintaining and improving the risk level (DNV)
- Guideline to subsea integrity management – wellhead to topside ESDV (Wood)
- Integrity management and condition monitoring of pipelines and subsea equipment (DNV)
