Propeller thrust and virtual speed log for higher accuracy on propulsion performanceApril 2, 2019
As regulations push up fuel costs, ship-owners are always looking out for the newest technology that can optimise the propulsion performance of their fleet. The Vessel Performance Optimisation (VPO) conferences provide a platform for ship-owners, - operators and - managers to meet and discuss about how the industry can improve their operational efficiency. On March 14th 2019, The Digital Ship organised the VPO forum in Cyprus where ship-owners had the opportunity to meet propulsion performance experts from around the world to discuss the newest technologies that can optimise their fleet’s performance. VAF Instruments’ Area Sales Manager Hans Paul was one of the featured expert speakers.
The measurement of Speed Through Water (STW) of a ship is vital for performance monitoring, Hans said. However, there is a risk of errors in accuracy depending of the speed log measurement principle and when done without the knowledge of a performance analyst. Hence why Hans Paul gave a presentation about how using a propeller thrust and virtual speed log can give higher accuracy on propulsion performance than Big Data. In his presentation he enlightened how thrust measurement by TT-Sense® separates propeller performance from hull performance and how this optical sensor is also the solution for accurate STW measurement.
Hans Paul also explained that data collection of all the relevant sensors on board of various ships of a fleet can result in unmanageable large amount of data. Propulsion Performance Management is the solution. From ship to shore, VAF’s IVY® provides data collection, enrichment and analysis for fleet and ship performance visualisation and insights into relevant KPI’s. IVY® really brings the fleet at your fingertips.
