During the period May 14-30, 2008, the Petroleum Safety Authority Norway (PSA) audited BP Norge AS' (BP) safeguarding of technical integrity for loadbearing structures on Valhall and Ula. On the basis of our findings during the audit, we have issued a notification of order to BP.

  • Opening meeting, May 14, 2008.
  • Meetings, conversations and verifications, May 27-30, 2008.

The background for the audit is the PSA's performance goals relating to follow-up of major accident risk, and is an activity within the PSA's prioritized follow-up of the petroleum industry's work on technical condition and ageing of facilities.

The purpose the audit was to verify that BP has management systems which reduce the risk of structural failure on ageing facilities, and that BP has qualified solutions for handling technical integrity in loadbearing structures, so that the intention of the applicable regulations is safeguarded.

The audit activity included BP's follow-up of its supervisor responsibility vis-a-vis its suppliers.

Nine nonconformities were uncovered during the audit, and we have identified one area with potential for improvement.
