Classification society DNV has awarded the Abate (P+) notation to Stena Evolution, confirming that the drillship’s power generation systems are designed and controlled under a defined framework supported by an emissions and energy management system aligned with ISO 50001 principles.
The notation verifies that both technical and operational measures aimed at reducing power demand and greenhouse gas emissions have been installed and implemented on board. According to Stena Drilling, these measures include closed-bus operation during dynamic positioning, freshwater generation systems, LED lighting upgrades, enhanced hull features, and systematic fuel-use tracking.
Power and fuel consumption are monitored through smart metering, with operational data made available via Kognifai dashboards. The company said these tools support consistent visibility of energy performance across onboard systems.
The Abate (P+) notation was granted following DNV’s document review and an initial survey confirming that the specified measures were in place and functioning as intended. Stena Drilling positioned the certification within its wider programme focused on energy efficiency, data transparency, and continuous improvement across the fleet.
According to the company, Stena Evolution is the first drillship worldwide to achieve the Abate (P+) notation.
Stena Evolution is a seventh-generation ultra-deepwater DP3 drillship, capable of operating in water depths of up to 3,658 m and drilling to depths of 12,192 m.
Andrew Calderwood, Energy Performance Superintendent at Stena Drilling, said the notation reflects sustained engineering work, data-driven optimisation, and close collaboration with partners to deliver emissions reductions while maintaining operational capability. He added that the company intends to build on this platform and extend proven solutions across the fleet.
Lars Tore Haug, Head of Section for Offshore Safety and Systems at DNV, said the Abate framework is intended to help offshore operators demonstrate structured and transparent emission-management practices to stakeholders. He also highlighted the cooperation with Stena Drilling during the assessment process.
