The Oseberg Vestflanken 2 consists of three oil and gas structures in the North Sea, about eight kilometers north of the Oseberg field centre.
The field will be developed with an unmanned wellhead platform. The wells will be remote-controlled from Oseberg field centre.
Wellhead platforms without living quarter, helideck and lifeboats is a new concept in Norway, but is in use on the Danish and Dutch continental shelves.
On 9 and 10 February 2017, we carried out an audit of Statoil's management of the design and fabrication of the control cable that will connect Oseberg Vestflanken 2 with the Oseberg field centre. The audit took place at the premises of the supplier, Technip, in Newcastle.
The background to the audit included a number of incidents linked to control cables on the Norwegian Continental Shelf, as well as information in the plan for development and operation (PDO) for the development. The control cable is considered to be a safety-critical component, since it will be the only channel for communication and power supply between the field centre and the unmanned facility at Vestflanken 2.
The audit is founded on our main theme for 2017 – "Reversing the trend" – and in particular on the pillars of robustness and standardisation.
No regulatory non-conformities were detected during the audit.
However, an improvement point was identified relating to document management.
We have asked Statoil to notify us by 28 April 2017 as to how the improvement point and one other comment in the report will be assessed.
