Wärtsilä Electric Propulsion Systems
The Wärtsilä electric propulsion system has a unique system configuration to maximize safety and efficiency.
The Wärtsilä low loss concept is a patented solution developed to enhance redundancy and to reduce the number of components in the system. The concept is flexible and can be designed to fit any configuration of power generation and propulsion units, as well as other onboard electric power consumers.
In addition to tailor made solutions, the low loss concept is available in five standardized systems: the Wärtsilä LLC 1500, 2700, 3800, 5000 and 10,000, indicating the maximum power of each of the two main propellers. For vessels with large power generation and power consumption, a medium voltage system is available.
The system can be combined with Wärtsilä’s variable speed drives for powering up to 10 MW propulsion units. The system can also be combined with any configuration of power generation units, and can be custom designed to meet specific requirements for flexible power distribution in a variety of different applications. A combination of a medium voltage system for power generation, and a low voltage system for power distribution to the ship consumers and any special purposes, will enhance the flexibility and increase the operability of the vessel.
Delivered in 2009, the 92 m Platform Supply Vessel ‘Viking Lady’ has a Wärtsilä Ship Design and combines four Wärtsilä 32DF dual-fuel engines with advanced vessel automation and Wärtsilä’s Low Loss Concept. »
Designed by Wärtsilä Ship Design and delivered in 2009, the AHTS ‘Siem Pearl’ features Wärtsilä’s Low Loss Concept and two Wärtsilä 16V32 engines, two gearboxes and two controllable pitch propellers. »
