During the period 13-14 December 2005, we conducted an audit at Gassco AS targeting how the company fulfills the Major Accident Regulations at the Kollsnes facility. We did not find any nonconformities in relation to the regulations in the area covered by the audit.

The gas is compressed at Kollsnes before it is sent to the Continent.

Gassco is operator of Gassled. Statoil is the technical service provider, and is responsible for the daily operation of the Kollsnes facility.

Background for the audit

The Petroleum Safety Authority Norway (PSA) is to set the standards and follow up to ensure that the players in the petroleum activities maintain high standards in the field of health, safety and environment. Through this, the PSA shall also contribute towards creating the greatest possible value for the Norwegian society.

Furthermore, the PSA shall contribute towards reducing the risk level in the petroleum activities by following up to ensure that the players facilitate technical and operational integrity in the activities.

The Norwegian authorities are required to conduct annual checks to ensure compliance with the requirements in the Major Accident Regulations. This audit is based on the Major Accident Regulations, whose purpose is to prevent major accidents involving dangerous chemicals, as well as to limit the consequences a major accident could have on human beings, the environment and material assets.

Purpose of the audit

The objective of the audit was to consider whether the management of the activities entails sufficient control over factors related to the risk of a major accident, including training/competence, mechanical integrity, technical changes and operational procedures.

Result of the audit

We have not identified any regulatory nonconformities within the area covered by the audit.

We have received the impression that satisfactory work is carried out to inform the public about the activities at Kollsnes.

Statoil has initiated a project aimed at identifying outstanding maintenance per discipline so as to improve the overview of general outstanding maintenance.

Statoil is currently working on preparing a governing document describing development and maintenance of competence. This document will apply to all disciplines.

The following items with improvement potential were noted:

  • Procedures for updating the process and instrument diagrams (P&ID).

  • Inspection of temporary equipment.

  • Follow-up of disconnected safety functions
