Background for the audit
ConocoPhillips has for about ten years had procedures that involve emergency preparedness with wave notification, as well as mitigation measures and evacuation of personnel when there is a warning of big waves.
The PSA wanted to confirm that the intentions in the resolutions regarding Ekofisk area subsidence are complied with. We also wanted to verify that ConocoPhillips has documented compliance with the regulations for facilities where no measures are carried out.
Purpose of the audit
The task comprised notification of waves and establishing emergency preparedness with Værvarslinga på Vestlandet (the weather forecast for Western Norway) and with the helicopter company. Furthermore, calculation of wave heights for measures and what measures are carried out to limit pollution and personal injuries.
The PSA wanted to compare with earlier storms and check that one was able to document measures in accordance with plans and implemented measures. The storm "Gudrun" on 8 and 9 January 2005 was chosen as an example.
To limit the task, we focussed on Ekofisk Q, Ekofisk C and Eldfisk A.
Result of the audit
Our main impression from the audit is positive. ConocoPhillips has implemented and described emergency preparedness measures that include notification of wave situations, measures to limit the damaging effects of big waves and evacuation of personnel. The personnel also receive regular training in the form of drills.
The audit found no non-conformities with the regulations. However, the report indicates four improvement areas related to the analysis of oil tanks below deck, the handling of storm risk in risk assessments, methodology regarding risk-reducing measures and pile fatigue analysis.
