Report following audit of barrier management on Sleipner A, T and R

During the period 21 March – 8 April 2011, the Petroleum Safety Authority Norway (PSA) carried out an audit of the Sleipner A, T and R facilities. The audit followed up how Statoil maintains and ensures compliance with barrier management requirements.

The objective of the audit activity was to assess Statoil’s planning, implementation and follow-up of activity on Sleipner in relation to relevant regulatory requirements.

One of the PSA’s main priorities is maintaining barriers. Through our work, we are aware that the players have implemented regulatory requirements relating to barriers to varying degrees in accordance with the intention. Errors and deficiencies in one or more barrier elements’ performance are general causal factors of incidents. Strategies and processes for making barriers robust in the different phases of a facility’s life cycle have developed in different directions and have varying degrees of maturity. We see a need to highlight common denominators and complementary properties between the barrier elements’ condition and performance, operation and maintenance management and risk management.

The audit activity identified nonconformities in relation to the regulations relating to:
- testing of valves critical to safety
- identification and follow-up of barrier elements
- fire division in fire pump room
- evacuation
- follow-up of assumptions in risk analyses
- barriers and barrier elements
