Audit of wells, barriers and well control - Scarabeo 5

On 30 October 2006, the Petroleum Safety Authority Norway (PSA) conducted an audit of Saipem SpA Norwegian Branch (Saipem). The audit targeted technical and operational aspects associated with wells, barriers and well control in connection with drilling using the mobile drilling facility Scarabeo 5.

We were informed that extensive inspection/control/audit of the well control equipment was carried out by the operator and hired inspection firms in 2005. Similar audits are also scheduled for the near future.

Background for the audit

Storting White Paper No. 12 addresses topics such as major accidents. In that connection, the PSA has initiated a series of activities in the area of drilling and wells in order to see how the industry is working to avoid major accidents. Similar audits have been conducted with several drilling contractors and operating companies in recent years.

Purpose of the audit

The purpose of the audit was to obtain an overview of the company's management system to ensure well safety in the ongoing activity, as well as to verify compliance with relevant regulatory and internal company requirements in this area.

Result of the audit

During the audit we revealed nonconformities related to follow-up of the personnel's competence/training.

We have also identified potential for improvement linked to the following factors:

  • Order competence in connection with repairs.

  • Transfer of experience to brand supplier of BOP.

  • Handling nonconformities on test intervals on BOP (14 day test).

  • Training system (on the job training).

  • Well control training.

  • Deficient overview of errors that occur during testing of the pressure control equipment.

  • Registration and follow-up of technical inspection conducted by ModuSpec and Statoil.


The audit was reduced in relation to the originally planned scope, based on submitted documentation and information that Statoil and the consultant firm ModuSpec had conducted technical verifications of the well control equipment during the 2005-2006 time period.

The scope, results and status of improvements for the findings in these reports were presented. We have no comments as regards these findings, and assume that they will be corrected as presented and planned by Saipem.
