Transocean Norge becomes first semisubmersible to earn DNV notation for GHG abatement

The Transocean Norge was the first semisubmersible to receive DNV’s Abate (Power+) notation, following upgrades designed to lower its greenhouse emissions during operation. The notation is designed to reflect the best industry practices in greenhouse gas abatement for offshore units.

In DNV’s Abate (Power+) class notation is a comprehensive energy and emission management system aligned with ISO 50001 standards. It emphasizes rigorous monitoring of energy consumption and the implementation of both operational and technical strategies to notably reduce emissions.

Transocean implemented several key strategies to ensure the rig meets these standards. These included comprehensive monitoring of energy consumption, optimization of operational energy, use of closed bus ties to minimize the number of idle engines and variable frequency drives in rotating machinery to optimally control the power for large rotating machinery.
