Audit of technical conditions on Veslefrikk

Audit: During the period 16 February - 27 March 2009, the Petroleum Safety Authority Norway (PSA) conducted an audit of StatoilHydro on the Veslefrikk facilities. During the audit, we followed up how StatoilHydro safeguards and ensures compliance with requirements related to fire and explosion protection, electrical and instrumented safety systems. We identified five non-conformities in relation to the regulatory requirements.


The audit was conducted as meetings and interviews with personnel in the operations organisation at Sandsli during week 8, and through verifications, function tests and interviews with offshore personnel during week 13.

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, thereby also contributing towards creating the greatest possible values for the Norwegian society.

The background for this audit activity is ongoing evaluations of the application for consent to a lifetime extension for Veslefrikk. It is a main priority for the PSA to ensure that a prudent safety level be maintained on facilities and installations which are planned for use beyond their original lifetimes.

Purpose of the audit
The purpose of the audit was to contribute to and verify that StatoilHydro plans, manages and conducts its activities according to the HSE regulations in an efficient and goal-oriented manner.

During the audit we emphasised the following items:

  • Fire and gas detection.
  • Processes safety and emergency shut-down.
  • Ignition source control.
  • Active and passive fire protection.
  • Emergency power and emergency light.
  • Alarm handling.

Result of the audit
Our main impression after the audit was positive, but certain challenges emerged relating to process safety and active and passive fire protection.

We identified five non-conformities in relation to the regulatory requirements. These are related to dependence between the regulation function and process safety, follow-up of HIPPS valves, the fire water system, passive fire protection and escape routes from rooms with high voltage installations.

The audit report also contains items with a potential for improvements.
