Audit of Transocean Arctic

We have carried out an audit of Transocean Arctic in respect of structural safety.


On 4 and 5 April 2017, we carried out an audit of the Transocean Arctic mobile drilling facility in the domain of structural safety.

The audit was conducted at Transocean's premises at Forus in Stavanger and addressed primarily robustness, lifecycle challenges and barriers within structures and marine systems, as well as analyses of waves on deck.

The audit is founded on our main theme for 2017 – "Reversing the trend" – and in particular on the pillar of robustness. During the audit, we focused on robustness in the context of ageing mechanisms. Transocean Arctic was built in 1984 and upgraded in 2004. The facility received Acknowledgement of Compliance (AoC) in July 2004.

No regulatory non-conformities were detected during the audit.

However, improvement points were identified relating to:

  • Follow-up of condition reports
  • Operational criteria for bringing the facility into a safety condition
  • Updating of stability manual
  • Condition monitoring of seawater pipes
  • Differences in light ship displacement

Transocean has been asked to report on how these improvement points will be assessed by 19 May 2017.
