Background for the audit
After having completed audits of mobile drilling facilities and the ship owners in 2000 and 2003 respectively, audits on selected permanent facilities with drilling equipment were planned and completed in order to verify similarities and potential differences related to well control and well control systems between permanent and mobile facilities, as well as between drilling and well interventions. This audit is included in this series of audits.
This audit covers an important area within health, environment and safety which we want the companies to focus on.
The audit includes a review of selected parts of the companies' systems and routines within the following areas:
Competence and training related to well control
Implementation and documentation of well control drills
Testing, maintenance and complete overhaul of the well control equipment/BOP
Documentation of competence requirements, testing and equipment maintenance
Interfaces between operator and drilling contractor
Involvement of and relations to equipment supplier and independent verification
Handling of deviation
Purpose of the audit
The purpose of the audit was to verify that current regulations and the company's routines have been maintained with regard to maintenance and complete overhaul of well control equipment and within well control training for drilling and well activities.
Result of the audit
Hydro and Prosafe have clearly defined requirements regarding basic competence within well control for relevant drilling position on the same level as elsewhere in the industry.
We note that Prosafe and Cameron have carried out a complete overhaul of the well control equipment in 2004.
The scope of the work has been clarified between the companies and no deviations have appeared in the final documentation with regards to the technical requirement specifications for such equipment.
The audit has revealed deviations from the Norwegian regulations requirements related to maintenance management and independent verification.
We have found some points for improvement in Cameron, Prosafe and Hydro related to:
Lack of/inadequate involvement and follow-up regarding complete overhaul of well control equipment
Lack of independent verification regarding complete overhaul of drilling and BOP
Control and supervisory responsibility
Offshore well control drills
Well control course based on International Well Control Forum (IWCF) and the need for additional training
Transfer of expertise
