Audit of electrical systems and instrumented safety systems – Kristin

During 1-4 November 2010, the Petroleum Safety Authority Norway (PSA) carried out an audit of the Kristin facility. The audit followed up how Statoil safeguards and ensures compliance with requirements for electrical systems and instrumented safety systems.

The audit activity was carried out in the form of a meeting with the operating organisation in Trondheim on 1 November, and subsequent verifications and interviews with personnel offshore.

Kristin is a gas condensate field in the Norwegian Sea that is developed with a seabed facility with four templates and Kristin Semi, a semi-submersible facility for processing. The Kristin field started production in 2005. The Tyrihans seabed facility is tied into Kristin and started production in 2009.

The audit activity is related to the PSA’s main priority of technical and operational barriers. This main priority’s goal is to ensure that technical and operational barriers are maintained in a consistent manner so that the risk of major accidents is reduced as much as possible.

The PSA will set the premises for, and follow up that the players in the petroleum industry maintain a high level of health, safety, environment and preparedness, and through this also contribute to creating the greatest possible values for society.

The purpose of the audit activity was to assess how planning, implementation and follow-up of the activity is maintained, with regard to regulatory requirements within the audit’s subject area.

The audit activity was carried out with good facilitation by Statoil. The PSA’s impression is that the general condition within the audit’s subject areas is good.

The audit identified three nonconformities in relation to the regulations. They are related to execution of internal company audits of electrical systems, updating technical operating documentation and isolating ignition sources at the highest emergency shutdown level.
