How efficient is your vessel being operated? Do you measure key performance indicators such as fuel consumption, shaft power or speed over ground? 

“If you don’t measure it, you can’t improve it”

VesselTrak provides an easy and low cost method to provide the answers to these questions. Using real-time measurements of KPI’s, allows you to maximise fuel savings, reduce emissions and extend maintenance intervals for your vessel or fleet. 


VesselTrak performance and efficiency monitoring system provides the means to monitor and control key performance indicators such as:


Specific Fuel Consumption (SFC)


Fuel Consumption per nautical mile


Fuel Consumption Rate L/Hr


Main Engine RPM


Main Engine Output Power


Shaft Output Torque


Vessel Speed

1. TorqueTrak shaft torsionmeter. Measures the true mechanical power output of the engine by combining a torque measurement (using a strain gauge) with shaft speed measurement in a simple algorithm. The signal is then transferred off of the shaft using wireless telemetry. In contrast to other methods, strain gages have proven to be the most accurate, robust, and reliable method for measuring torque on a shaft.

2. Fuel flow meters. Measures the consumption of fuel flow via a pair of screw-driven volumetric flow meters. The meters are installed in-line to the supply and return lines. With automatic temperature compensation and back-flow protection, an accuracy of 1% is achievable.

3. ECR display screen. Integrates the signals from the shaft torsion meter, fuel flow meters, and other existing measurements (such as generator power or vessel speed) and displays them via a panel-mount touch-screen display. The display is capable of USB data-logging, outputting signal into MODBUS/RS-485, and connecting to a vessels internet for cloud-based monitoring. The display is also compatible with a wheelhouse repeater for monitoring from the bridge.

4. Online cloud monitoring. Op-Fleet technology provides the cloud-based interface to monitor the efficiency of a single vessel or an entire fleet. The data is automatically uploaded from the OP-HMI engine control room (ECR) display via an internet connection on-board a vessel or automatically stored and downloaded when the vessel returns to internet service at dock.
