Audit - emergency preparedness on the Transocean Leader

On 30 April 2004, the Petroleum Safety Authority Norway (PSA) conducted a verification activity on board the drilling rig Transocean Leader during its stay at the Westcon yard in Ølen. The audit targeted management systems and technical elements relating to emergency preparedness.


Background for the audit

The Transocean Leader (photo) is a semi-submersible mobile drilling rig delivered by Hyundai Heavy Industries in Korea in 1987. The rig has been in operation on the British shelf until December 2003.

The rig was prepared in Ølen for a planned start-up of drilling activities for Norske Shell on production license PL255 in May 2004.

Transocean Offshore (TO) applied for an Acknowledgement of Compliance (AoC) for the rig in December 2003.

Upgrades were to be made on the rig during its stay at the yard in Ølen. Some of the work is being done to comply with requirements in the regulations (regulatory requirements), and it is a precondition that this work be completed before start-up of activities on the Norwegian shelf.

Purpose of the audit

The objective of this activity was to verify whether management and technical elements in the area of emergency preparedness on the Transocean Leader, are in compliance with regulatory requirements.

Result of the audit

The planned modifications on the Transocean Leader will help to improve the rig's HSE standard.

An extensive program of maintenance and testing of systems must be implemented before the rig is ready to commence operations, in addition to training and drills for the crew.

TO plans to carry out such a program during the rig's stay at the yard in Ølen.

During the verification, the rig was only partially manned with operations personnel, thus making it difficult to verify compliance with the requirements for competence and familiarization, training and drills.

It will be a challenge for the company to commission the installation (with the necessary documentation) for operation while also ensuring that the regulatory requirements in the above-mentioned areas are safeguarded.

No new non-conformities within the area of emergency preparedness were identified during the verification.

The Petroleum Safety Authority Norway sent the audit report to Transocean Offshore on 21 June 2004.
