Powering the world’s navies and coast guards

Through innovative solutions and services, Wärtsilä sets out to be the most valued business partner with products that are capable of meeting the most stringent special naval requirements, such as noise reduction and shock resistance.

Our experience in providing propulsion, powering, and environmental solutions for Navy and Coast Guard vessels is long standing, and more than 90 countries entrust Wärtsilä with the supply of equipment for their naval fleet. Wärtsilä was selected by BAE Systems (Marine) Ltd., to supply its Membrane Bioreactor technology for wastewater management onboard the British Royal Navy’s latest class of warship.

Wärtsilä is the leading provider of environmentally and economically sound integrated solutions, with a marine industry offering that includes engines, generating sets, reduction gears, propulsion equipment (propellers, shafts, thrusters), waste water treatment, automation and power distribution systems, as well as sealing solutions.

Wärtsilä is unique in being capable of supporting the lifecycle of a vessel by being involved at all stages, from the conceptual design, to construction, and throughout the operational life of the vessel:

  • Complete power and propulsion systems, and solutions from bridge controls to environmental seals, with integrated solutions tailored to actual operational needs.
  • Unnoticeable noise and vibration based on engineering expertise acquired through years of experience
  • Total service packages covering start-ups, installation, engineering work, maintenance, repairs, and more
  • Service points around the globe and remote monitoring around the clock


Wärtsilä integrates its systems in an environmentally and economically sound way for the greater benefits of its customers:

  • Single responsibility, reduced risk of incompatibilities, classification for complete systems
  • Less co-ordination work between parties meaning time-savings in design, engineering and the purchasing process
  • Extended intervals between overhauls, and the replacement of parts at the optimal time
  • Complex wastewater management


With us as your service partner you receive notable measurable benefits, such as availability and performance, productivity gains, and cost efficiency. Above all, we offer peace of mind in the knowledge that your installation is being serviced by the most experienced partner you could have.
