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 21 to 23 May 2019, we carried out an audit of the electrical facilities and technical safety for Deepsea Yantai while it was berthed at the 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 (AoC).
The objective of the audit was to verify the technical condition and relevant parts of the management system in order to monitor that requirements in the petroleum regulations were being met.
Non-conformities were identified relating to:
- Completion and verification of technical facilities
- The AoC application – inadequate descriptions of modifications
- Electrotechnical system analyses
- The fire water system
- Area classification and associated requirements
- Inadequate ignition source decoupling
- Pneumatic fire doors
- Emergency lighting installation
- Emergency power system
- High voltage installation
- Electrical facilities – technical conditions
In addition, improvement points were identified relating to:
- Deficient positioning and protection of fire and gas detectors
- Defects in system for preventing gas dispersal
- The mud laboratory
- Deficiencies in documentation
- Deficiencies in insulation of foam cannon on helideck
- UPS systems – protection of sensitive electronics
- Non-conformity handling
What happens now?
We have asked Odfjell to report to us by 30 August 2019 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.
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.
