Odfjell Drilling has applied for an AoC for the Deepsea Aberdeen mobile drilling facility.

In connection with an AoC application, the PSA conducts audits within selected specialist domains.

From 18 January to 5 February 2021, we carried out an audit of Odfjell within the domains of drilling and well technology and maintenance management for the Deepsea Aberdeen mobile facility.


The objective of the audit was to verify the technical condition, organisation, operational preparations and relevant documents in the management system in order to monitor compliance with the petroleum regulations.


During the audit, five regulatory non-conformities were identified. These concerned:

  • Storage and handling of explosives
  • Updating of and compliance with procedures
  • Marking
  • Signage
  • Maintenance management

Four improvement points were also identified, concerning:

  • Overview of the valve manifold area
  • Adaptation of maintenance to special operating conditions
  • Classification of systems and equipment
  • Maintenance programme

What happens next?

The report contains a description of identified non-conformities and we have asked Odfjell to report on how these non-conformities will be addressed. The company has also been asked for its assessment of the improvement points observed.

Before we issue an AoC, the company must have corrected all known safety-critical non-conformities, and the facility must have been issued with maritime certificates from the appropriate flag state.
