Songa Management AS receives AoC for Songa Delta.

The Petroleum Safety Authority Norway (PSA) has granted an Acknowledgement of Compliance (AoC) for the Songa Delta semi-submersible drilling facility.

On 8 November 2012, Songa Management AS received an Acknowledgement of Compliance (AoC) for the Songa Delta drilling facility.

What is an AoC?
An Acknowledgement of Compliance (AoC) is a statement from the PSA confirming that a mobile facility is considered to be in compliance with relevant regulatory requirements for petroleum activities. The AoC scheme also encompasses the company's safety management system.

The PSA bases its decision on information provided by the applicant in a separate AoC application regarding the technical condition of the facility, as well as the applicant's organisation and management system.

After an AoC is granted, it is the shipowner's responsibility to ensure that the organisation, management system and the technical condition of the facility comply with the regulations at all times.

If a facility operates outside the Norwegian shelf, the owner can decide whether or not to maintain the AoC. If the owner chooses to maintain the AoC, then the owner is obliged to ensure compliance with the preconditions stipulated for the AoC at all times.

Facts about Songa Delta
Songa Delta is a third generation Ocean Ranger type mobile drilling facility, commissioned at Rauma Repola in Finland in 1981.

The facility has been modified several times, and is registered in Norway with Det Norske Veritas (DNV) as classification society.


Songa Delta and relevant parts of Songa Management AS' organisation and management systems have been assessed as being in accordance with relevant regulatory requirements for the petroleum activities.

The validity of this AoC is contingent on Songa Management AS ensuring that the facility and relevant parts of the company's organisation and management systems are maintained, such that terms and assumptions in the PSA's decision are safeguarded.
