The audit was conducted from 31 January to 3 February 2022.


The objective of the audit was to verify that Transocean’s management of maritime systems on Transocean Norge complied with relevant regulations.


Two non-conformities and eleven improvement points were identified.

The non-conformities concerned:

  • The watertight and weathertight barrier
  • Control and indication in the ballast control system

The improvement points included:

  • Special conditions for operation
  • Procedure for handling stability incidents
  • Freeboard plan
  • Deficient maintenance of watertight sliding doors
  • Damage to weathertight closures
  • Misleading indication at ballast control station
  • Control of the ballast system
  • Deficiencies in barrier management
  • Analogue indication in the ballast system
  • Lack of training in emergency operation of the ballast system
  • Deficient maintenance of safety-critical ballast components

What happens now?

We have asked Transocean to report to us on how the non-conformities will be addressed and for their assessment of the improvement points observed.
