Abstract
Disclosed are a method and a virtual sensor system for determining the speed through water of a marine vessel. The method includes obtaining propeller revolutions per minute and at least one of torque at propeller, propulsion power, thrust and engine fuel flow, obtaining speed over ground of the vessel and using the obtained data and hydrodynamic modelling to determine the speed through water of the vessel.
Claims20
A method for determining speed through water of a vessel for optimisation of vessel operation, using a sensor system, the method comprising:
- obtaining data regarding propeller revolutions per minute and at least one of torque at propeller, propulsion power, thrust or engine fuel consumption;
- obtaining data regarding speed over ground of the vessel;
- and
- using the obtained data and hydrodynamic modeling to determine speed through water of the vessel.
A sensor system for determining speed through water of a vessel, the sensor system comprising:
- a first receiver configured to receive propeller revolutions per minute and at least one of torque at propeller, propulsion power, thrust or engine fuel consumption;
- a second receiver configured to receive speed over ground of a vessel;
- and
- at least one processor configured to determine a speed through water of a vessel, based on received data and hydrodynamic modeling.
The sensor system according 19, in combination with a vessel whose speed is to be determined by the sensor system.
