What is a Marine Shaft Power Meter and How Does It Work?
A marine shaft power meter measures the torque and rotational speed (RPM) of a vessel’s propulsion shaft to calculate the real power delivered to the propeller. This makes it significantly more accurate than engine based data, which does not account for transmission losses or propeller efficiency variations. It can be installed directly on the shaft without dismantling it, ensuring minimal downtime during retrofits or sea trials. This technology is widely used in performance verification and testing, such as on the sea trials page. It provides reliable propulsion insight for efficiency optimization and predictive maintenance strategies onboard vessels in real operating conditions. sea trials.

Applications: Why Measure Shaft Power on ships?
Fuel Efficiency Monitoring and Emissions Compliance
Measuring shaft power alongside fuel flow, combustion performance, and vessel speed provides a complete picture of propulsion efficiency. This data helps operators identify opportunities to reduce fuel consumption and optimize engine loading across different operating conditions. Accurate performance monitoring also supports compliance with emissions regulations such as CII and EEXI. Learn more about engine performance
Predictive Maintenance and Propulsion Diagnostics
Changes in shaft power and torque can indicate early signs of degradation in engines, propellers, gearboxes, or bearings before a failure occurs. Continuous monitoring allows operators to identify performance losses, investigate abnormalities, and plan maintenance activities proactively. This predictive approach helps reduce unplanned downtime, lower repair costs, and minimize time spent in dry dock.
