Waterjets Midsize and Modular Solutions

Waterjets - Jet powered efficiency and reliability

When deciding on the right waterjet solution there are many variables to consider – from size, weight and power to efficiency, reliability, support and ease of integration. All of this can make it a complicate process, but it doesn’t have to be. At Wärtsilä we have been delivering waterjet solutions that meet customer needs and all these variables for over 40 years. ​

At the heart of this is our Smart Marine Vision, where collaboration and the most advanced digital technology come together to deliver solutions with greater efficiency, safety, security and reduced environmental impact throughout the life of the asset.​
