Benefits

Combines several engineering indicators rather than relying on a single fuel-consumption number. 

Actual vs Expected Power
The system compares the power presently required by the vessel with the expected power for the same operating condition. A sustained increase can indicate additional resistance or deteriorating performance.

Hull and Propeller Performance
Trends in power requirement, propeller slip and operating condition can help identify whether performance deterioration is likely to arise from hull fouling, propeller condition or other causes.

Fuel per Nautical Mile
Fuel consumption becomes more meaningful when related to transport performance. PropelSense tracks how much fuel is being used to move the vessel each nautical mile.

Eco-Speed
Rather than simply recommending the lowest possible speed, PropelSense seeks an efficient operating window that considers propulsion efficiency together with voyage and ETA requirements.

The result is a clearer understanding of what is changing, why it may be changing, and what action may be worthwhile.

PropelSense provide concise engineering advice to the people making the operating decision on board. 

Instead of presenting the crew with another complex dashboard, PropelSense aims to translate analysis into understandable advisories such as:

AMBER — Actual power is 7% above expected at the present speed. Increased hull resistance is indicated. Reducing RPM from 76 to 73 may improve fuel-per-mile performance while maintaining voyage requirements. Advisory confidence: High.

Each advisory is intended to show:

What has changed • Why it matters • What action is suggested • Expected benefit • Confidence of the advice

In short:

Not more data. Better decisions.
