EFMS by Ascenz

Deliver fuel data built to stand up to scrutiny, reliably

Our Electronic Fuel Monitoring System combines certified sensors and automated data collection to deliver verified, realtime and reliable fuel data for confident operational and commercial decisionmaking.

Fuel is one of the largest operational costs and risk factors for marine operations, and a key source of commercial risk under charterer scrutiny. Yet fuel data is often disputed, fragmented, or unreliable.

Operators, owners and charterers need a trustworthy, auditable view of fuel usage to avoid financial losses, commercial disputes and loss of contract confidence. EFMS delivers continuous, automated and tamper-proof monitoring of fuel consumption, bunkering and vessel activities, removing uncertainty around fuel data.

Key features

Fuel consumption monitoring

Monitor fuel consumption continuously and at high frequency across engines and operational modes.

Bunkering monitoring

Measure and verify bunkering operations using mass flow measurement and detailed bunker profiles.

Activity monitoring

Track vessel activities manually and automatically to correlate fuel use with operations.

ROB tracking

Calculate and cross‑check remaining fuel on board to detect inconsistencies and improve transparency.

System & data integrity monitoring

Continuously verify sensor availability, data consistency and overall system health to ensure longterm reliability and confidence in the data.

Key benefits

Trusted, tamper‑proof fuel transparency

Provide secure, auditable fuel and energy data backed by certified sensors and anti‑tampering mechanisms. Deliver accurate and reliable fuel data that holds up under operational, commercial and audit scrutiny.

Reduced fuel losses and disputes

Detect anomalies, bunkering discrepancies and unauthorized fuel usage at an early stage.

Operational and commercial control

Support performance management, charter‑party discussions and dispute resolution with reliable data. Support crews, shore teams and management with simple, usable fuel insight—on board and ashore.

Subtitle

Improved fuel efficiency

Identify inefficiencies and reduce unnecessary consumption through activity‑aware fuel insight.

Fleet‑level consistency

Scale trusted fuel monitoring from individual vessels to entire fleets. Ensure consistent fuel data, usage and reporting across vessels, contracts and charter periods.
