Transocean Endurance is a semi-submersible CAT D rig, classified by DNV-GL and owned and operated by Transocean.
Our decision is based on the information provided in the AoC application concerning the technical condition of the facility and the applicant's organisation and management system, as well as the authorities' verifications and other case processing.
The validity of the Acknowledgement of Compliance assumes that Transocean ensures that the facility and relevant parts of the company’s organisation and management systems are maintained so as to fulfil the terms and conditions set out in the PSA’s decision.
Audits in connection with the AoC application
The facility first received an AoC in 2016. It was then named Songa Endurance, and was owned and operated by Songa Offshore.
At that time, the PSA carried out audits of a number of selected domains:
- Drilling and well technology, process integrity incl. maintenance and electrical facilities
- Emergency preparedness
The AoC case processing also included audits performed in respect of an AoC for Songa Equinox, which was the first of the CAT D rigs (the reports are attached).
When Transocean took over Songa Offshore in 2018, the company applied for a new AoC for Songa Endurance. The company has changed the name of the facility to Transocean Endurance and implemented Transocean’s management system, as described in the new AoC application. The PSA has monitored this process through meetings and a separate audit of the integration between Transocean and Songa.
