Audit of electrical and safety systems on Sleipner

During the period 8-11 November, the Petroleum Safety Authority Norway (PSA) conducted an audit of electrical and safety systems on Sleipner. The audit covered parts of the electrical disciplines as well as safety systems.

The audit focused on:

  • Qualifications of electrical professionals
  • Backlog of critical electrical and safety maintenance
  • Internal control of electrical systems
  • Verifications in documentation and electrical systems
  • Test of safety systems

Sleipner lokasjonskart
Sleipner is located in the southern part of the North Sea. The Sleipner Vest field was proven in 1974. The field is tied in to Sleipner Øst (proven in 1981), and the fields are operated by the same operations organization.

Background for the audit
The PSA sets the standards for and follows up to ensure that the players in the petroleum activities maintain a high level of health, safety, environment and emergency preparedness, and through this also contribute to creating the greatest possible value for the society.

The PSA shall contribute towards reducing the risk level in offshore petroleum activities by following up to ensure that the players facilitate the technical and operational integrity of the installations, as well as following up the man-technology-organization interplay in critical HSE systems.
This includes audit activities targeting Statoil in 2004 for the purpose of verifying:

  • that governing documentation exists and is complied with
  • that the players facilitate and maintain the technical integrity of the installations.

In 2004, Sleipner has experienced a great deal of activity as regards implementation of projects and modifications.

Purpose of the audit
The goal of the audit was to verify that Statoil plans, implements and follows up the activities in accordance with regulatory requirements related to electrical and safety systems.

Result of the audit
The general impression was that the installations were both tidy and clean.
The audit activity proved several non-conformities with the regulations. None of these were serious enough, neither individually nor jointly, to constitute a basis for an order.

The audit report also addresses items where there is a potential for improvement.

We noted a relatively high number of hours of outstanding work, and the trend over the past year has been negative.

We also noted equipment that was not included in the maintenance system.
There was a good overview of temporary equipment on the installation, but there was a lack of clarification as regards responsibility for maintenance.
During the audit we conducted functional tests of the emergency/escape route lighting and fire and gas detection systems. The tests of the fire and gas detection systems proved certain insufficient actions as regards documentation for the systems.

The Petroleum Safety Authority Norway thanks Statoil for its capable facilitation and good cooperation during implementation of the audit.
