Background for the audit
In the appointment letter issued by the Ministry, the Petroleum Safety Authority Norway (PSA) is required to
Our experience from audit activities in 2001, 2002 and 2003, as well as reported incidents from Eldfisk, also help make up the basis for the audit.
Purpose of the audit
The objective of the audit was to verify that safety is ensured through management of technical and operational factors in connection with planning and execution of activities.
Another objective was to verify that CoPNo follows up undesirable incidents in a satisfactory manner through registration, internal and external reporting, identification of causes and actions, as well as to utilize experience gained from incidents in preventive safety work.
Result of the audit
1.1 Maintenance management
1.1.1 Prioritization of maintenance tasks
There are no execution deadlines associated with priorities stipulated for M1 notifications/ PM02 work orders. This is a deviation from the requirements set forth in Section 45 of the Activities Regulations relating to planning and prioritization.
1.1.2 Consequences of outstanding maintenance
The audit focused on the quality of maintenance management, as this is a prerequisite for safeguarding the technical condition of the systems.
There is a large volume of outstanding maintenance on Eldfisk.
CoPNo refers the fact the objectives linked to outstanding maintenance are based on trends and not on the overall outstanding volume of maintenance.
The criteria for concluding whether or not the volume of outstanding maintenance is acceptable are unclear.
CoPNo has a good overview of the status of maintenance for the most safety-critical systems on Eldfisk.
However, no practice has been established to ensure that the consequences of the outstanding maintenance overall are considered when activities are planned.
A process has been initiated to establish such a practice based on a semi-annual review of total outstanding maintenance.
1.2 Use of experience from incidents
We experienced good communication regarding incidents on board Eldfisk, and there was emphasis placed on reporting all incidents.
Incident history and observations are used to a limited extent in the preventive safety work. Analyses are conducted of incident history, but it has not been documented that these results are used to identify measures for improvement.
1.3 Function testing
Four function tests have been conducted on safety systems. Most of them functioned satisfactorily, except for an N2 accumulator test.
