Mærsk Gallant and Ekofisk Bravo
Background for the audit
Storting White Paper 12 (2005-2006) places emphasis on major accidents. In this connection, we are implementing a series of activities in the drilling and well area in order to motivate and see how the industry is working to avoid major accidents. Similar audits have been performed in relation to several drilling contractors and operating companies in recent years.
The PSA conducted a well control audit of CoPSAS and Odfjell in May 2004 (link). The operator's measures following that audit will be followed up and verified as part of this planned audit.
Ekofisk/Eldfisk have experienced repeated well control incidents and have shown only marginal improvement over a period of ten years. We plan to follow up the company's work to improve these conditions as part of this audit.
Purpose of the audit
The purpose of the audit was to clarify how the company's management system for safeguarding health, environment and safety functions in connection with well safety, as well as to verify compliance with HSE requirements laid down in statutes and regulations, particularly in connection with training and competence related to drilling and well activities.
Result of the audit
During the audit we identified one nonconformity in relation to regulatory requirements.
This nonconformity is linked to uncertainty as to whether enough is being done to reduce the likelihood of new well control incidents. There is, however, focus on measures to reduce the consequences of incidents. The regulations prioritize measures to reduce the likelihood of incidents occurring, ahead of measures to reduce the consequences of incidents that do occur.
The operator's and the drilling contractor's statistics as regards well control incidents have a potential for improvement.
Several improvement items were noted and the companies should investigate these further and implement improvement measures as soon as possible.
