Singapore tanker shipping company AET has featured Daphne Technology in its annual review of the company’s sustainability strategy, in connection with direct emissions capture.
The review highlights AET’s pilot of Daphne Technology’s PureMetrics system as part of efforts to improve emissions transparency and explore methane reduction strategies.
As part of a pilot project, the PureMetrics system was installed on two of AET’s LNG dual-fuel vessels — Eagle Ventura (Aframax) and Eagle Bintulu (VLCC). The technology enables real-time measurement of engine emissions, providing greater visibility into vessel performance and helping AET evaluate emerging solutions for methane capture, which are in early stages of development and review. PureMetrics supports AET’s broader digitalisation roadmap and regulatory preparedness under frameworks such as the EU ETS, the IMO Data Collection System (DCS), and performance standards like CII and EEXI.
Jamie Brick, Interim CEO, Daphne Technology, said: “We are pleased to work with AET on this important initiative. Their leading role in piloting emerging technologies and their commitment to sustainability have made the collaboration both productive and insightful. AET’s use of PureMetrics reflects a practical and forward-looking approach to emissions transparency, and their engagement has provided valuable operational input that continues to strengthen the technology.”
PureMetrics generates operational insights helping shipowners and charterers improve emissions transparency, quantify methane slip, and prepare for upcoming regulatory requirements. The system measures both CO₂ and methane (CH₄) directly from engine exhaust in real time, supporting compliance with regulatory frameworks. By delivering real-time emissions data from multiple engine stacks, PureMetrics is able to strengthen GHG accounting and compliance readiness across dual-fuel vessel operations.
Designed for integration on LNG dual-fuel, gas-powered, and conventional engine vessels, PureMetrics is a modular emissions monitoring system that enables direct measurement of methane slip and CO₂ directly at the exhaust outlet. It aligns with EU MRV and upcoming IMO methane regulations, and provides a foundation for meeting carbon intensity and carbon pricing requirements in maritime operations.
