The audit was carried out between 2 and 5 March 2015.

Maersk has applied for an Acknowledgement of Compliance for the Maersk Invincible drilling facility.

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

From 2 to 5 March 2015, we carried out an audit of Maersk’s follow-up of the working environment and materials handling/logistics in respect of the design engineering of the Maersk Invincible jack-up rig. The audit took place at the shipyard in South Korea. During the audit, the facility was in the process of being prepared for operation on the NCS.


The objective of the audit was to verify that the project has established necessary management systems and associated processes in the engineering and fabrication phase to facilitate the future operation of the facility within the regulatory requirements applicable on the NCS, as concerns the working environment and logistics and materials handling.

In addition, the audit aimed to help increase regulatory understanding among the different project participants by sharing some of the PSA’s experiences from previous newbuild projects and experiences from processing AoC applications.


In the working environment domain, the audit identified three non-conformities concerning:

  • Control of governing documents
  • Unclear requirements regarding individual working environment conditions
  • The Action Tracking Register

In addition, five improvement points were identified concerning:

  • The working environment programme
  • Technical responsibilities (authorities) in respect of the working environment
  • Organisational and staffing studies
  • Noise exposure predictions for groups of personnel
  • CRIOP analyses

In the logistics domain, the audit identified two non-conformities concerning:

  • Pipe handling deck/drill floor/moonpool
  • Loading hose stations

In addition, three improvement points were identified, relating to:

  • Materials handling approaches
  • Supply deck
  • Offshore cranes

What happens now?

We have asked Maersk to report by 30 May 2015 on how the non-conformities will be handled and for their assessment of the improvement points.

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.
