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 or logged data from one or more speed through water logs of the vessel and using the obtained data and hydrodynamic modelling to determine the speed through water of the vessel.

Method and system for optimising operation of vessel

An exemplary sensor device provides marine vessel data of a marine vessel without integration to the marine vessel's information systems. The sensor device includes a receiver configured to receive at least position and time information relating to the marine vessel. At least one sensor is configured to measure marine vessel performance data. The at least one sensor can measure the marine vessel performance data when the sensor device is affixed to the hull structure of the marine vessel. At least one processor is configured to perform frequency analysis of the measured marine vessel performance data and to generate marine vessel data based on the received at least position and time information and the frequency analyzed marine vessel performance data.
