Audit of Transocean Winner

During the period 23-30 May 2006, the Petroleum Safety Authority Norway (PSA) conducted verifications in the areas of working environment, electrical disciplines, technical safety and emergency preparedness on the Transocean Winner facility, at the workshop in Ølen. The verifications were linked to Transocean's application for an Acknowledgement of Compliance (AoC) for the facility. It is our impression subsequent to the audit that the project is well managed, and it is likely that the tasks will be completed as expected.

Background for the audit

Transocean Winner (see photo) is a semi-submersible facility, type GVA 4000, built in 1983. Transocean initially applied for an AoC for the facility in January 2002, but withdrew the application as the facility was laid up in Ølen.

The new AoC application was submitted on 3 March 2006, and the verification activities are part of the authorities' processing of the application. The facility has a contract with Norsk Hydro.

Purpose of the audit

The purpose of this activity was to verify that factors in the areas of working environment, electrical disciplines, technical safety and emergency preparedness comply with the regulatory requirements. To some extent, the verification also included management issues within these areas.

The verification was carried out on the basis of information received in connection with the company's AoC application.

Result of the audit

It is our opinion that the project is well managed, and it is likely that the tasks will be completed as expected.

No new nonconformities were identified during these verifications, but we did note areas for improvement within all of the technical disciplines.

There were many simultaneous projects underway at the workshop and generally hectic activity, which led to somewhat less focus on orderliness and tidiness than one would expect on an active facility. We were told that this would be rectified before the facility left the workshop.
