Stena Carron becomes the second Stena Drilling drillship to be awarded DNV’s Abate (P) notation
Following the success of her sister vessel, Stena DrillMAX, Stena Carron has become the second Stena Drilling drillship to be awarded DNV’s Abate(P) notation.

This achievement reflects the company’s commitment to reducing greenhouse gas emissions through the implementation of advanced technical and operational measures.
The DNV Abate(P) notation is industry-recognised for representing best practices in emissions abatement. As oil and gas operators and drilling contractors align to reach their net-zero targets, the Abate(P) notation marks a significant step in this journey, acknowledging units that demonstrate concrete progress in emission reduction.
By achieving this prestigious notation, Stena Drilling reinforces its ambitious emissions reduction as part of its sustainability objectives. The company has implemented a range of technical and operational enhancements, including:
- Real-time energy and emission monitoring
- Enhanced control of large pumps to optimise power usage
- Elimination of additional fuel burning in boilers by the installation of Reverse Osmosis freshwater production plants and electric lube oil heaters
- Hydraulic ring line EcoBoost accumulator system
- Energy Awareness training for all personnel, on and offshore
Stena Drilling has also adopted a certified ISO 50001 energy management system across the fleet, as part of our ongoing strategy to reduce our carbon footprint.
Andrew Calderwood, the Energy Performance Superintendent at Stena Drilling, highlights the significance of the Abate (P) notation, emphasizing that it serves as a formal recognition of the energy efficiency initiatives successfully implemented on the Stena Carron. He further acknowledges the ongoing commitment of the vessel’s crew and engineering support teams in maintaining a high level of energy awareness. Their dedication to sustainable operations and continuous improvement plays a crucial role in enhancing the vessel’s overall efficiency and reducing its environmental footprint.
Erik Rønsberg, CEO of Stena Drilling, said: “I’m delighted that we have achieved this notation for Stena Carron. We have made significant investments in equipment, training and awareness in our fleet and being awarded this Class notation aligns us well with our values of care, innovation and performance.”
