Engineering audit on 2/4M jacket

On 26-27 June 2003, the Norwegian Petroleum Directorate (NPD) conducted an audit of the engineering of the jacket for the Ekofisk 2/4M installation. ConocoPhillips was notified by letter concerning the audit, which was carried out in AkerKværner's offices in Lysaker.

Background for the audit

The audit was based on the NPD's priorities for facilitating and maintaining technical integrity of installations.

The NPD has recorded two quality nonconformances in connection with jacket projects in recent years: driving of the piles for the Valhall Injection Platform (IP) and fatigue damage during transport of the Kvitebjørn installation.Investigations have been conducted of the Valhall IP and Kvitebjørn incidents.Both of the specified nonconformances represent challenges as their causes are not fully understood. This places even greater demands on personnel responsible for engineering as various potential causes of defects must be prevented.

Therefore, the NPD is concerned with ensuring that the players on the shelf use their experience to implement improvements related to technical, human and organizational factors.

The purpose of the audit

The purpose of the audit was to verify that ConocoPhillips and AkerKværner are conducting the engineering work by utilizing methods for investigation and exchange of experience and finding qualified solutions during the engineering, thereby ensuring that current requirements in the petroleum regulations are observed.

Another objective was to check that the management systems help contribute to involving the right competence at the right time, and that communication with adjoining disciplines such as maintenance is satisfactory so that robust solutions are selected.

ConocoPhillips' safeguarding of its duty to ensure the contractors' proper management of the engineering was also evaluated.
