Odfjell has applied for an Acknowledgement of Compliance (AoC) for Deepsea Yantai.

In connection with an AoC application, the PSA conducts audits within selected specialist areas. From 4 to 6 June 2019, we carried out an audit of logistics and maintenance management for Deepsea Yantai while it was berthed at CIMC Raffles shipyard in Yantai, China.

Deepsea Yantai was originally ordered by North Sea Rigs, and was registered at the time under the name Beacon Atlantic. The facility was built in China by CIMC Raffles between 2012 and 2016, since when it has been laid up at the shipyard. Odfjell has been contracted by Neptune Energy Norge to use the facility on the Norwegian Continental Shelf, for which purpose it has applied for an Acknowledgement of Compliance (SUT).


The objective of the audit was to verify that the regulatory requirements for logistics and maintenance management were being fulfilled.


Non-conformities were identified relating to:

  • The AoC application
  • Materials handling
  • Certification of lifting equipment
  • Maintenance management
  • Maintenance of offshore cranes
  • Unclarified aspects of logistics

In addition, an improvement point was identified in relation to the handling of cuttings.

What happens now?

We have asked Odfjell to report to us by 30 August 2019 on how the non-conformities and improvement point will be addressed.

For us to issue an AoC, all known safety-critical non-conformities must be rectified and the facility must have been issued with maritime certificates from the relevant flag state.

What is an Acknowledgement of Compliance?

An Acknowledgement of Compliance (AoC) is a statement from us expressing the authorities' confidence that petroleum activities can be performed by a mobile facility in compliance with the regulations.

The AoC decision is based on information provided by the applicant in an individual application. The document must cover technical aspects of the facility and the company's organisation and systems for safety management.

The details are verified by us by means of spot checks in selected areas. This is done through audits and/or by putting questions to the drilling contractor.
