Audit of electrical operations on Ekofisk and Tor

In the period 23 - 27 February 2004 the Petroleum Safety Authority Norway (PSA) conducted an audit of ConocoPhillips Norge's electrical operations on the Ekofisk Bravo/Kilo and Tor installations (photo).

Background for the audit

It is an essential prioritiy for our HSE follow-up to ensure that the players facilitate and maintain technical integrity on the installations.
The Petroleum Safety Authority must follow up the players own evaluations of technical condition and maintenance. This follow-up must be coordinated with the PSA's own verifications on the installations.

Purpose of the audit

The purpose of the audit was to verify that ConocoPhillips follows up the Ekofisk B, Ekofisk K and Tor installations in accordance with the current regulatory requirements and recognized norms in the electrical and technical safety disciplines.

Result of the audit

The audit revealed some deviations from the regulatory requirements. None of these was so serious that they would constitute a basis for an order, neither individually nor following an overall assessment.

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

The operator documented that regular verifications of the electrical facilities were conducted.

Spot tests conducted by the PSA revealed examples of insufficient follow-up of identified deviations.

A review of temporary equipment on board the installation showed that this was followed up in accordance with the recognized norm.

The PSA found examples of drawings and circuit lists that had not been updated in accordance with changes in the facilities.

The audit included function tests related to the system for emergency power supply, emergency lighting/escape lighting and detection systems for fire and gas. No serious faults or defects were discovered through these tests.
