Audit of Statoil - Troll C

Between 28 and 31 January 2014, the Petroleum Safety Authority Norway (PSA) carried out an audit of barrier management, technical safety and electrical systems at Troll C.

The objective of the audit was to verify whether Statoil's management and monitoring of barriers at Troll C was in accordance with the company's and statutory requirements, so as to reduce the likelihood of failures.

Non-conformities were identified in connection with:

  • labelling of battery banks

In addition, improvement points were identified in connection with:


  • response time for fire water
