From 18 to 26 September 2019, we carried out an audit of Aker BP and Maersk Drilling relating to their planning and execution of drilling and well operations at Valhall Flank West using Maersk Invincible.
Objective
The objective of the audit was to verify that Aker BP and Maersk Drilling, together with the subcontractors, are meeting the regulatory requirements for planning, risk assessment and execution of drilling and well operations at Valhall Flank West. This included verifying that all participants in the activity were aware of and understood their own responsibilities.

Three non-conformities were identified in connection with:
- Storage of radioactive sources (Maersk Drilling)
- Maintenance programme (Maersk Drilling)
- Inadequate transfer of experience (Aker BP and Maersk Drilling)
Four improvement points were identified in connection with:
- Unclear roles and deficient requirements for conducting training and exercises (Aker BP)

What happens next?
