Audit of Statoil – Gullfaks B

From 18 April 2013 to 14 June 2013, the Petroleum Safety Authority Norway (PSA) carried out an audit of Statoil and Gullfaks B.

The object of the audit was to verify that Statoil had established the necessary requirements and systems to ensure that well barriers and well control equipment with associated control systems were followed up and safeguarded in a comprehensive and consistent manner, and that risk was sufficiently reduced.

Non-conformities were identified in connection with:

  • safety-critical valves
  • testing of well control equipment
  • testing of valves

In addition, improvement points were identified in connection with:

  • governing documents
  • data on annular pressure build-up
