Audit of helicopter deck on Mærsk Giant

During the period 7-9 February 2011, the Petroleum Safety Authority Norway (PSA) carried out an audit of the helicopter deck on Mærsk Giant, with technical assistance from the Civil Aviation Authority - Norway (CAA).

The audit mainly focused on the design of and equipment related to the helicopter deck, and was carried out while the facility was on assignment for the operating company DONG on the Trym field. The CAA contributed to the audit in its capacity as technical assistance authority for the PSA.

The background for the audit activity was that Mærsk Drilling Norge AS (Mærsk), upon request, could not produce documentation verifying that the actual design of the helicopter deck, in accordance with requirements in the Norwegian Maritime Directorate’s Regulations relating to helicopter decks.

Pursuant to Section 3 of the Framework Regulations, Mærsk has used maritime regulations as a basis instead of technical requirements stipulated in and in pursuance of the Petroleum Act. The audit was therefore carried out with a basis in the Norwegian Maritime Directorate’s rules for mobile facilities.

The audit identified two factors that were deemed to warrant immediate action, relating to the fire pumps’ foam capacity and available firefighting equipment. These circumstances were immediately rectified by the company.

Furthermore, the company has been requested to describe how the other proven nonconformities and improvement items will be handled, with a deadline of 1 April 2011.
