VAF Instruments’ Optical Thrust & Torque Measuring System (TT-Sense), with an optional connection to a Propulsion Efficiency Monitor (PEM), captures and displays propeller thrust, shaft power, torque and speed details on a compact display.
Due to IMO regulations, a SEEMP (*Ship Energy Efficiency Management Plan) is mandatory, as of 2013, for all vessels on their first renewal or intermediary survey. Several TT-Sense measurements will contribute to complying with this requirement.
VAF’s TT-Sense provides details on propeller efficiency, hull resistance and vessel pitch optimization. The real-time measurements assist with propulsion monitoring, which can contribute to decreased fuel costs and a potential indicator of malfunctions in the propulsion system.
TT-Sense® enables fuel cost reduction through:
Besides the standard output of a thrust, torque, shaft speed and power signal, the TT-Sense® can be combined with VAF fuel consumption flow meters and can be extended with energy consumption and propeller shaft analysis. Cumulatively resulting in even larger efficiency!
