Marine propulsion systems and gears

Marine propulsion systems and gears from Wärtsilä are designed to make your ship more efficient, save fuel, and cut emissions.

Marine propulsion systems and gears

Marine propulsion systems, solutions, and services from Wärtsilä deliver efficiency, safety, and manoeuvrability. The thrusters portfolio offers solutions for manoeuvrability and station keeping for all vessel types. Waterjet propulsion solutions are available for any ship size. You will also find a wide offering of marine gears.

The propulsion system is key when looking for ways to improve your vessel’s operational efficiency. They also help you save fuel, decrease emissions and as a result, decarbonise your operations. The special energy saving technologies have been designed just for that purpose.

What about services?

Wärtsilä’s propulsion solutions and gears 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.

How to maximise safety and manoeuvrability

Offshore applications require cast-iron safety and excellent manoeuvrability. The traditional way to improve dynamic positioning (DP) capability has been to add more powerful thrusters or increase propeller diameter. This comes at a cost because the weight and complexity of your vessel will increase.

Instead, you will want to find the optimal configuration for propulsion. Wärtsilä’s OPTI-DP Engagement Tool can calculate and quantify the propulsion options early in the design phase. This means that you can configure your engines accurately and thereby save fuel.

Diesel electric propulsion

Electric marine propulsion is a flexible and future-proof choice for ships.  Flexibility safeguards you from the uncertainty about the availability and cost of sustainable fuels, for example.

You need flexibility if you are not sure about the additional power sources that will support your combustion engines, and if you do not know exactly which operational profiles will be sailed.
