Wärtsilä provides propulsion systems and power generation systems for frontline vessels. We work in close co-operation with the customer to select the most appropriate solution, focusing always on performance, reliability, low lifecycle costs, and integrated logistical support.
The increasing importance of stealth and shock resistance capabilities in fighting vessels, means that the already reliable technology used for commercial vessels requires significant enhancement. Through the development of innovative and integrated solutions, Wärtsilä strives to be the most valued business partner with products that are capable of meeting the most stringent special naval requirements.
High shock resistance, low noise, minimal vibration levels
Navy applications typically specify high shock resistance, low noise and minimal vibration levels. This requires tailor-made solutions that are based on standard equipment. Wärtsilä works closely with navies, coastguards, and shipyards starting from the design phase of the vessel, in order to meet the end-user’s prerequisites. Our expertise in complete solutions also results from our long-standing collaboration with the major institutes in terms of research and hydrodynamic studies.
Unique to Wärtsilä is the delivery of Waterjet And Refined Propeller (WARP) systems. These systems combine controllable pitch propellers with a waterjet. The benefit is that the largest parts of the total installed vessel power can be absorbed by the waterjet. Despite the high level of power, the dimensions of the jet remain relatively small, thanks to the high allowed power density compared to a propeller.
WARP system benefits
With the jet taking most of the total vessel power, the propellers can remain small in diameter and the draft of the vessel can be limited. The result is a very attractive operational profile. The propellers are fully optimized for lower cruising speeds, delivering optimum efficiency with low noise and little vibration. At the same time, the combination of the waterjet and propellers still gives access to higher speeds when required.
