Audit of electrical systems, safety systems and maintenance management on Rowan Stavanger

During 27 – 28 April 2011, the Petroleum Safety Authority Norway (PSA) carried out an audit where aspects related to electrical and safety systems and maintenance management were the topics for follow-up on board the Rowan Stavanger facility.

The PSA’s activity was carried out as part of the processing of the company’s application for an Acknowledgement of Compliance (AoC) for Rowan Stavanger as a living quarters facility. The facility will initially be used as a living quarters facility on the Yme field, but may be used for drilling activity on the Norwegian shelf in the future.

The objective of the audit activity was to verify technical and management-related aspects on the facility within the relevant disciplinary areas.

Within electrical and safety systems we noted that internal training was not carried out in accordance with the requirements. As regards safety management in general, documentation was not updated and facilitated for the operations phase, but was prepared to satisfy requirements during the design and construction phase.

Within maintenance management, the audit was carried out in the form of verifications and spot checks on the facility, as well as a review of the company’s governing documents and procedures in addition to conversations with relevant personnel. Verifications of safety-critical equipment and parts of the maintenance system were carried out. Circumstances related to training in the company’s maintenance system, STAR, were also reviewed, in addition to the history of commissioned equipment. The drilling equipment on board was not subject to verifications during this audit.

We were informed that the number of physical tags was approx. 23 000, of which approx. 5000 were safety-critical equipment. Criticality assessments had been carried out on approx. 50 per cent of the equipment. This will be concluded before start-up on the shelf.

The audit identified some new nonconformities and general comments, but the overall impression within the maintenance management discipline was positive as compared with the previous activity on Rowan Gorilla IV, carried out in 2009. Our discoveries were related to deficiencies within equipment labelling, internal procedures are not followed within nonconformity handling and reporting, lacking certificates, incorrect test interval of safety-critical valves and training.
