Objective
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.
Result
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.
Oseberg
Oseberg is a field in the northern part of the North Sea. The water depth in the area is 100 metres. Oseberg was discovered in 1979, and the plan for development and operation (PDO) was approved in 1984. The field has been developed in multiple phases. Production started in 1988.
The Oseberg Field Centre includes three platforms, Oseberg A, B and D, connected to one another with bridges, in the southern part of the Oseberg field, and the Oseberg C platform, which lies 14 kilometres north of the field centre.
