Daphne Technology’s PureMetrics™ continuous emissions monitoring system (CEMS) has received a Factual Statement from Lloyd’s Register (LR).
The assessment confirms the system is suitable for continuous monitoring of selected greenhouse gas emissions from marine diesel engines.
LR reviewed the system’s design, emissions calculation methodology and onboard demonstration tests.
Unlike a vessel-specific approval, the assessment applies to the PureMetrics™ design itself. Shipowners can use it as the basis for vessel-specific monitoring plans and certification.
PureMetrics™ is designed to monitor carbon dioxide (CO₂), methane (CH₄), carbon monoxide (CO), nitrogen oxides (NO and NO₂), and sulphur dioxide (SO₂). It is suitable for marine diesel and dual-fuel engines, including LNG-fuelled vessels.
LR also approved Daphne Technology’s emissions calculation methodology based on UN TOOL08.
“Although IMO and EU frameworks recognised CEMS as a method for measuring greenhouse gas emissions, LR and Daphne Technology began this appraisal before specific statutory guidelines were available,” said Max Wu, Lead Specialist on Engine and Emissions Certification Service at Lloyd’s Register. “The new IMO guidelines now provide a clear path for CEMS approval.”
“Receiving the Lloyd’s Register Factual Statement is another important step for PureMetrics™,” said Ivan Raleff, Managing Director of Daphne Technology. “It confirms the system meets regulatory requirements across a broader range of greenhouse gases.”
The validation follows a DNV Statement of Compliance issued in April 2026. Together, the two approvals strengthen the technical foundation for direct emissions monitoring as methane reporting requirements expand under the EU MRV and EU ETS.
