Our offering at a glance

As a company with the most comprehensive portfolio at hand in the industry, we turn technology into solutions to enable a sustainable maritime industry. We have recognised and analysed that the journey to lowering GHG emissions requires combining data and technology like Wärtsilä’s hybrid solutions or Air Lubrication System with green fuels and biofuels to meet the short-term targets.

This means that the powertrain systems for vessels are fuel flexible and can be retrofitted and upgraded to run on green fuels. Our portfolio of engines, propulsion systems, hybrid technology, and integrated powertrain systems deliver the reliability, safety, and environmental performance.

    Air Lubrication System


    AIR LUBRICATION SYSTEM

    The Air Lubrication System (ALS) creates a thin layer of air made up of uniform micro bubbles, as small as 1-3 millimeters in diameter. The micro bubbles reduce the drag on the vessel, which in turn lowers thrust requirements and decreases the amount of engine power needed to propel the vessel.
