The audit was carried out between 13 February and 24 April 2024 and is part of our case processing of Shelf Drilling’s application for an Acknowledgement of Compliance (AoC) for Shelf Drilling Barsk.


The objective of the audit was to verify that the company’s maintenance management system operates in compliance with the regulatory requirements.


The audit identified non-conformities in the following areas:

  • The AoC application and compliance measurements
  • Technical barriers
  • Operational and organisational barriers
  • Requirements for analyses
  • Competence
  • Security clearance of activities
  • Maintenance
  • Classification
  • Maintenance programme
  • Planning and prioritisation
  • Maintenance effectiveness
  • Systems and equipment
  • Follow-up

What happens now?

We have asked Shelf Drilling to report on how the non-conformities will be addressed.
