Audit: AoC verification on Leiv Eiriksson

The Petroleum Safety Authority Norway (PSA) conducted an audit from 13-15 November 2007 on the Leiv Eiriksson facility at the shipyard in Las Palmas, Grand Canaria. The audit targeted factors within the areas of working environment, emergency preparedness, marine systems, drilling and wells, cranes, lifting equipment and maintenance.


The audit aimed at management of working environment factors was carried out in the form of meetings at Ocean Rig AS' (OR's) offices at Forus on 9 and 26 November 2007. The audit linked to working environment did not include verifications on board the facility.

Leiv Eiriksson

Background for the audit
The audit was linked to OR's application for an Acknowledgement of Compliance (AoC) for the mobile drilling facility Leiv Eiriksson.

The facility will be used by Norske Shell, which plans to use the facility on two wells on the Norwegian continental shelf. After its stay at the yard in Las Palmas, the facility will proceed to the Irish and British continental shelves for well assignments, after which it will proceed to the Norwegian continental shelf in May/June 2008.

During the audit, the Leiv Eiriksson was at the shipyard in Las Palmas for necessary maintenance and upgrades.

Purpose of the audit
The purpose of the audit was to verify that management and technical factors within the areas of working environment, emergency preparedness, marine structures, lifting operations, maintenance management and drilling on the Leiv Eiriksson are in accordance with regulatory requirements.

Result of the audit
During the audit, modifications, upgrades and necessary maintenance activities were underway on the facility, after several years of drilling operations on foreign continental shelves.

We identified a number of new nonconformities and improvement items within all of the verified technical areas. Our verification is based on spot checks, and a total of 41 nonconformities and 26 factors with potential for improvement were revealed. The AoC applicant has not previously informed the authorities regarding these nonconformities, nor has it applied for exceptions.

We noted that a large part of the crew had only been on board for a short time, and therefore had limited knowledge of the facility, its systems and equipment. This was the case for both existing and new equipment. In addition, we noted incomplete and deficient training among the crew.
