During the period January 8-10, 2008, the Petroleum Safety Authority Norway (PSA) conducted an audit of the mobile drilling facility West Phoenix at the Samsung shipyard in Korea. The audit targeted drilling systems, electrical systems, technical safety systems and working environment conditions on the facility. The audit was conducted by means of document reviews, conversations and verifications on board the facility.
The audit was linked to Seadrill Management AS' application for an Acknowledgement of Compliance for the mobile facility West Phoenix. During the audit, the facility was undergoing commissioning at the shipyard in Korea.
According to the plan, the facility will commence drilling activity on the Norwegian continental shelf around June 2008.
The purpose of the audit was to verify that management and technical aspects related to the drilling systems, electrical systems, technical safety systems and working environment are in compliance with current regulatory requirements.
During the verification of the drilling equipment, extensive activity was underway on the facility related to connection of equipment and systems. About 15-20% of the drilling systems had undergone a commissioning test at the component level.
The plan included commissioning of some of the systems during the voyage from Korea to Norway. Plans had also been laid for coordination and training of the drilling crew on the equipment.
During this audit activity, the PSA found one nonconformity in relation to regulatory requirements, as well as one improvement item. Verification of the electrical systems and safety systems provided a good main impression of both equipment and installation within these technical areas. However, four new nonconformities were identified.
In the area of working environment, the project group conducted a number of verifying measurements and possesses a good overview of the factors that constitute regulatory nonconformities. Active work is underway to correct the identified nonconformities and unfortunate circumstances.
During the audit, it was not possible to obtain a complete overview of working environment conditions on the facility. This is due to the fact that certain working environment factors can only be mapped and verified when the facility has commenced normal operations, or has been further commissioned/completed. This relates e.g. to factors linked to noise (area and exposure noise), lighting, ventilation, safety signposting and psycho-social factors. During the audit we identified some nonconformities related to the absence of verification activities and to the physical design of certain areas on the facility.
