Propeller solutions enabling energy savings

    Propellers are the unseen workhorse of a vessel and are also a great way to deliver efficiency and manoeuvrability improvements. Wärtsilä propeller solutions are designed for specific vessel need and operating profile to ensure that the propulsion system uses the energy as efficiently as possible and thereby reducing fuel consumption and related emissions, all contributing to the decarbonisation of the marine industry.
