Major accident audit and audit of management and follow-up of technical and operational condition at Kårstø

During the period 19-21 September 2007, the Petroleum Safety Authority Norway (PSA) conducted an audit of Gassco AS: Major accident audit and audit of management and follow-up of technical and operational condition at the Kårstø land facility. It is our assessment that the facility does not fully comply with the regulatory requirements for maintenance management.


The audit covered the following topics and areas:

  1. Maintenance and inspection
  2. Potential for major accidents
  3. Aging of technical equipment
  4. Verifications

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 towards creating the greatest possible values for the Norwegian society.

This follow-up shall be system-oriented and risk-based, and shall come in addition to the follow-up the industry itself is responsible for.

The audit was based on the Major Accident Regulations and requirements in the provisional regulations relating to safety and working environment for certain petroleum facilities on land and associated pipeline systems (provisional regulations) and the Regulations relating to systematic health, safety and environment work in enterprises (the Internal Control Regulations / the HSE Regulations).

Purpose of the audit
The purpose of the audit was to investigate whether the operation of the Kårstø facility (pictured) meets the requirements in the Major Accident Regulations, with particular focus on evaluations and ranking of systems and equipment, as well as roles and responsibilities in this context.

A further objective was to obtain information regarding the technical and operational condition of the facility, as well as how the design life of important equipment and components is determined and safeguarded.

Result of the audit
The results are based on presentations of elements of the management systems and conversations with selected personnel, with subsequent verification of controlling documents and procedures, as well as the program for performing maintenance on the Kårstø process facility.

It is our assessment that the Kårstø facility does not fully comply with the regulatory requirements for maintenance management. The overall risk represented by outstanding maintenance, nonconformities and exceptions has not been evaluated. This constitutes an uncertainty in relation to the assumptions made for the technical condition of the facility in the risk analyses (TRA) and the safety report.
