Transocean – Transocean Norge – Integrity of Maritime Systems

Source: 4/7/2022, Location: Europe

The Petroleum Safety Authority Norway (PSA) has carried out an audit of Transocean Services (Transocean)’s management of stability, watertight and weathertight integrity, ballast systems, waves in deck and positioning on Transocean Norge.

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.
