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 domains.

From 30 September to 1 October 2019, we carried out an audit of drilling and well technology on Deepsea Yantai while it was berthed at the CCB yard in Ågotnes.

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 (AoC).


The objective of the audit was to verify the technical condition and relevant documents in the management system in order to monitor that requirements in the petroleum regulations were being adhered to.


Three nonconformities were identified in connection with:

  • Storage of explosives
  • Storage of radioactive sources
  • Maintenance programme

In addition, three improvement points were identified in connection with:

  • Training
  • Manometers
  • Connection of well testing equipment

What happens next?

Odfjell has been given a deadline of 28 November 2019 to report on how the non-conformities and improvement points 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.
