The audit was conducted between 19 and 29 September 2022.


The objective of the audit was to monitor that Halliburton follows up working hours, such that hazardous conditions are avoided, safe operations are ensured and the risk of failure, hazard and accident situations is reduced.


One non-conformity was identified concerning a breach of the working hours provisions.

In addition, an improvement point was identified concerning regulatory competence and interpretation.

What happens next?

We have asked Halliburton to report on how the non-conformity will be addressed. We have also requested an assessment of the improvement point identified. The deadline for reply is set at 3 January 2023.
