The audit was conducted on 21 June 2023.


The objective of the audit was to gain insight into the company’s governing documents, internal requirements, processes and procedures related to certification and recertification of drilling BOPs with control functions.

It was also important to verify that rolling five-year recertification is structured so as to ensure that all components are covered and that recertification can be documented at all times.


We identified two non-conformities during the audit. These concerned:

  • documentation of overhauling and recertification
  • specification of regulatory requirements

What happens next?

We have asked Transocean Services to report to us by 29 August 2023 on how the non-conformities will be addressed.
