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 and powering solutions for Navy and Coast Guard vessels is long standing: more than 90 countries entrust Wärtsilä with the supply of equipment for their naval fleet. Many of Wärtsilä products meet special naval requirements such as noise reduction and shock resistance. At Wärtsilä we optimise a vessel’s efficiency by looking at the whole picture. We study the vessel’s power and propulsion systems, the integrated automation systems, and the way that the vessel will be operated and maintained.

    Services worldwide 

    You can have the entire power or propulsion system fully serviced by one global supplier. We are continuously developing our global service network, solutions, products and specialist services worldwide to support equipment on board your vessels or power plant installations. Our Services & Support solutions range from basic support, installation and commissioning, performance optimization, upgrades, conversions and environmental solutions to service projects and agreements focusing on overall equipment performance and asset management. We deliver our services through our service stations, workshops and ship repair centres that form our service network in 70 countries worldwide.

    Complete propulsion solutions

    The global question behind the design of a vessel is the efficiency of the propulsion system. According to Wärtsilä, everything starts from the interaction between the hull and the propulsors. Then significant total savings can be found by optimizing the propeller design and matching it with the prime movers.

    Engine selection is another key element to improve the overall efficiency of a vessel. Wärtsilä is able to offer the configuration which provides the ability to match and run engines at optimal efficiency, this also includes hybrid solutions and the electrical and power management systems which are key to ensure safe and efficient operation. Wärtsilä delivers the optimum integrated solution tailored to the specific operating profile of each vessel.
