The audit was conducted on 23 and 24 May 2023.


The objective of the audit was to monitor whether DHO and its subcontractors are undertaking the planning and risk assessment of HPHT drilling operations in compliance with their own requirements, and the requirements in the regulations.


We did not identify any non-conformities during the audit.

We identified one improvement point concerning the requirements for well control expertise for certain subcontractors.

What happens next?

We have asked DNO to give us its assessment of the improvement point observed by 21 August 2023.
