Audit of the Mærsk Guardian AoC - electrical installations, technical safety systems and the working environment

Between 6 and 8 February 2007, the Petroleum Safety Authority Norway (PSA) conducted verification activities onboard the drilling facility Mærsk Guardian which was docked in a shipyard in Rotterdam to receive necessary maintenance and upgrading.

The activities were related to conditions regarding the working environment, electrical installations and technical safety systems. The activities were conducted through inspection of the records, conversations and verifications onboard the installation.

The report comprises identified deviations, and we have asked the company to provide a statement as to how these deviations will be dealt with. The report also includes observations on conditions with room for improvement, and we have requested an assessment of these conditions.

Background for the audit
The Mærsk Guardian is a jackup drilling facility built in 1986. The facility has previously operated on the Norwegian shelf and obtained an AoC on 1 Nov. 2002. Since then, the facility has been laid up or in operations abroad. The facility is now returning to the Norwegian shelf for drilling work for BP and other operators.

Purpose of the audit
The purpose of the audit was to verify that conditions related to working environment, electrical installations and technical safety systems complied with the regulatory requirements. The verification was implemented based on a former AoC application, along with information received in an application for consent from BP and information received from personnel from Mærsk Contractors Norge AS (MCN) at the shipyard in Rotterdam.

Result of the audit
During the audit we registered that MCN was well under way with rectifications of the identified working environment deviations. The lighting conditions had been improved in many rooms and noise control measures were underway in several areas. Likewise they were working to improve access to equipment units and also the ergonomic conditions on the installation.

We are of the opinion that MCN worked systematically to improve the identified working environment observations and deviations. No complete status report had been prepared, however, for the working environment conditions on the facility.

Some new deviations and room for improvement were uncovered during the audit.

During the time at the yard several electrical deviations were uncovered. Insufficient maintenance had led to some explosion proof equipment being in an unsound condition. The MCN was working to correct this, and the work seemed to keep a satisfactory standard.

As regard technical safety systems the work was underway to install a new Public Announcement system, in accordance with the regulations. This means that a long-term deviation can be closed.

No new deviations were uncovered for electrical and technical safety, although some points were found where there was room for improvement.
