Audit of Gyda: Technical and operational barriers – electrical installations

Audit: During the period 22-28 October 2009, the Petroleum Safety Authority Norway (PSA) conducted an audit of Talisman Energy Norge AS (Talisman) targeting how technical and operational barriers are managed on the Gyda facility. The audit was limited to the electrical installations discipline. We identified two nonconformities in relation to regulatory requirements.


The audit was carried out in the form of a start-up meeting with personnel in the operations organisation on 22 October 2009 and with subsequent verifications, function tests and interviews with personnel on Gyda (see photo) in Week 44.

Background for the audit
The PSA shall set the standards for and follow up to ensure that the players in the petroleum activities maintain high standards for health, safety and environment, and thereby contribute to creating the greatest possible value for society. Safety-critical barriers shall be handled in a comprehensive and consistent manner, so as to ensure maximum reduction of the risk of major accidents.

The follow-up shall be system-oriented and risk-based, and shall come in addition to the industry's own follow-up.

The audit is based on the directions given in the PSA's main priorities for 2009 on follow-up of technical and operational safety. The audit also addressed experience gained from previous audits, both of Talisman and of the industry in general.

Purpose of the audit
The purpose of the audit was to gain an overview of Talisman's systems and work processes for managing technical and operational safety related to electrical installations on Gyda, and to evaluate this in relation to the applicable requirements.

The audit emphasised the following topics:

  • Organisation and follow-up of operations and maintenance
  • Controlling sources of ignition
  • Competence and training
  • Identified findings and challenges from internal electrical audits
  • Function tests of selected safety systems

Result of the audit
We identified two nonconformities in relation to regulatory requirements. These were linked to control of ignition sources and signposting of doors to rooms with pressure monitoring.

The report also contains observations of factors where there is potential for improvements.
