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 optimizing operation of vessel

A method and system for determining a momentary boil-off rate for a storage tank for a natural gas in liquid phase and gas phase. A mass flow from the gas phase of the natural gas at an discharge pipeline of the storage tank and a mass flow into the liquid phase of the natural gas at an loading/discharge pipeline of the storage tank is determined. A volume, a temperature and a pressure of the gas phase of the natural gas is measured. A dynamical model is applied to the determined values to determine the momentary boil-off rate.
