Audit of follow-up of barriers at Kristin

From 19 to 22 March 2018, we carried out an audit of Equinor's (formerly Statoil) follow-up of vibration and cable chafing at Kristin. The audit also comprised general aspects of technical integrity and barrier management.


During 2017, it became known that Kristin had major problems with vibration and cable chafing. We had discussions and meetings with Equinor in the autumn of 2017 to find out the status of these issues and the measures that Equinor had implemented to protect the integrity of Kristin.

Vibration and cable chafing mainly concern the Tyrihans module and are largely due to the high speeds in the processing facility arising from its conversion to lower pressure production in 2014.

Because Equinor had not managed to acquire a full overview of the challenges of cable chafing and vibration, in autumn 2017, reinforced efforts on this issue were initiated. Equinor also conducted an internal audit of technical barriers on Kristin focused on leak prevention (vibration) and ignition source control (cable chafing).

Objective
The objective of the audit was to follow up Equinor's work on protecting integrity at Kristin and was primarily focused on factors relating to vibration and cable chafing.

We wanted to see the results of the measures undertaken, gain knowledge of the lessons learned during the improvement works, and be presented with an updated risk picture for Kristin.

Result
Three non-conformities were identified in connection with:

No improvement points were identified.

Equinor has been given a deadline of 15 June 2018 to report on how the non-conformities will be addressed.
