Audit of fire and explosion safety on Visund

In April 2008, the Petroleum Safety Authority Norway (PSA) conducted an audit of StatoilHydro ASA , directed at parts of the technical safety discipline on Visund. We identified, among other things, one non-conformity in relation to regulatory requirements.


The audit was conducted with a start-up meeting with the onshore organisation on 11 April 2008 and verification on Visund during the period 22– 24 April 2008.

In connection with the audit, we had conversations with relevant personnel, and we conducted tests and verifications in documentation and facilities.

We emphasised the following areas in particular: 

  • Explosion safety
  • Passive fire protection
  • Active fire protection
  • Fire and gas detection system
  • Emergency shutdown system

Background for the audit
The PSA is to set standards for and follow up to ensure that the players in the petroleum activities maintain high standards as regards health, safety and the environment, and thereby also contribute towards creating the greatest possible values for the Norwegian society.

The PSA shall also contribute to reduce the risk level in the petroleum activities by following up that the players facilitate technical and operational integrity.

Technical safety is a key component of the technical barriers, and safeguarding this in a good manner is important to maintain an acceptable risk level.

Purpose of the audit
The purpose of the audit was to confirm that StatoilHydro plans, manages and carries out its activities in manner that ensures that the operation and maintenance of Visund comply with applicable regulations and recognised standards.

StatoilHydro follows up the safety systems through  technical condition safety (Teknisk Tilstand Sikkerhet (TTS)) verifications. We therefore followed up reviews made in TTS during the audit.

Result of the audit
We identified one non-conformity from the regulatory requirements for firewater systems. It could not be documented that the fire pump systems had the level of reliability required by the regulations.

In addition, the report contains items where there is a potential for improvements.

During the audit activities, function tests were carried out in connection with selected safety systems. Errors uncovered during the tests are included in the report as improvement items.

Several of our observations in the report are related to the follow-up of TTS.
