The audit was conducted on 4-5 October 2016. This was a cross-disciplinary activity, concentrated on the configuration and preparations for use of the Oseberg H facility.


The PDO (plan for development and operation) for Oseberg Vestflanken 2, nine kilometres from the Oseberg field centre in the northern North Sea, was approved in June 2016.

The field is under development, with scheduled production start in 2018.

The development solution chosen for Oseberg Vestflanken 2 is a fixed, unmanned wellhead facility. The Oseberg H facility is a simpler structure, without emergency quarters or a helideck, but with a support vessel permanently moored to the facility while there are personnel present. This is a new concept on the Norwegian Continental Shelf.


The objective of the audit was to verify that the configuration and preparations for use of Oseberg H are compliant with the regulations, and that prudent operation of the facility has been provided for.


The audit identified three non-conformities. These included qualification and use of new technologies and new methods, as well as activities and evacuation.

Furthermore, improvement points were identified concerning simulation of gas dispersal, the basis of the maintenance programme, noise, illumination, and training and involvement of safety representatives.
