Wärtsilä hull and propeller performance optimised by Eniram

Wärtsilä Hull and Propeller Performance gives you visibility into your asset’s propulsion performance. The service allows you to optimize hull cleanings based on actual asset performance, as well as evaluate the impact of hydrodynamic investments like dry docks and retrofits.

All analysis is based on a unique model of your asset’s hydrodynamic characteristics combined with real-time information gathered by bridge and automation systems and sensors installed on the hull. This data is analyzed using advanced modeling that removes the impact of all extraneous variables to calculate one key performance indicator: how much propulsion power is needed to move the asset at a set speed in calm sea conditions?

With our service, you get a constant stream of propulsion power performance data that is comparable over time and across vessels – meaning you can track any decline in performance from hull fouling and evaluate if a cleaning is justified. You can also track changes in asset performance after hydrodynamic investments or evaluate optimum hull coatings by tracking performance differences between sister vessels.

    Key benefits

    • Optimize the timing of hull cleanings based on actual performance
    • Evaluate the impact on asset performance of hydrodynamic investments like dry docks and retrofits such as air lubrication systems
    • Compare performance between vessels to optimize your hull coating strategy

    Case: Optimizing hull and propeller performance

    Wartsila hull and propeller case

    Approximately 10% of the energy costs and emissions of the global fleet are due to poor hull and propeller performance, which translates into billions of dollars annually.


    The Insight Factory

    How it works 

    The Insight Factory

    Wärtsilä continuously collects information about the asset’s hydrodynamics as well as weather and currents, which is combined with data from bridge and automation systems and weather forecasts.

    The data is continuously analyzed by Wärtsilä’s advanced mathematical models tailored to each unique vessel to calculate the the calm sea propulsion power performance.

    The asset’s propulsion performance is displayed via the Wärtsilä Analytics tool.
