On 23 and 24 September 2014, the Petroleum Safety Authority (PSA) Norway carried out an audit of BP Norge AS (BP) and Valhall Flank North located in the North Sea.
The PSA says the audit was focused on working environment and emergency preparedness.
Valhall Flank North is an unmanned well head platform in the southern part of the North Sea, around six kilometers north of the Valhall complex. The platform is operated by BP. The Valhall Flank North came on stream in 2004.
