Propellers are the unseen workhorse of a vessel, and they have a huge impact on its efficiency, comfort, and manoeuvrability. The ship propeller solutions from Wärtsilä can match a variety of needs and ship operating profiles.
Propellers make the ship move through the water, and the choice of propeller influences the ship’s performance. When propellers work efficiently, the ship needs less fuel, and this also cuts its harmful emissions. This, in turn, contributes to the decarbonisation of the maritime industry.
Three factors have a big influence on your choice of propeller.
Wärtsilä can offer a wide range of propeller types which can meet the requirements of a variety of vessel types and operating conditions. For example, our portfolio includes both fixed pitch propeller (FPP) solutions and controllable pitch propeller (CPP) solutions.
Controllable pitch propellers allow for blade angle adjustments during operation. This allows for optimal operation during varying operating conditions. Examples of vessel that can benefit from a CPP system:
Fixed pitch propellers have blades that aren’t variable in pitch. As there isn’t a system required to actuate blades, they are considered the most robust type. They are the common choice for ocean-going vessels, such as:

Excellent performance and manoeuvrability for vessels with demanding operational requirements.
Optimal performance for a wide range of speeds and power densities.
Propeller blades can be replaced under water – a great choice when there is frequent risk of propeller damage.
An energy saving propeller cap with fins that rotate together with the propeller. This solution provides average fuel savings of 2%, with a payback time of less than one year.
Wärtsilä’s OPTI Design methodology can find a perfect match between the propeller, engine, and hull. For example, a propeller designed with the help of computational fluid dynamics (CFD) can lead to significant efficiency gains.
An innovative pre-swirl stator creates an optimal inflow for the propeller. It can improve propulsive efficiency by 2–7%.
Wärtsilä’s propeller solutions are designed for maximum durability. Still, proper maintenance and regular inspections are crucial for ensuring their longevity. We can support you with those, as well as with any unscheduled repair needs. We can also perform lifecycle upgrades at the same time as regular maintenance. This will not only save time but also money. Upgrades can also reduce your engine’s overall fuel consumption and emissions, which can bring you even more savings.
Propulsion services are available worldwide, regardless of the location of your assets. With this kind of support, you will be able to focus on your core business.
