As the popularity of diesel electric propulsion increases, attention is being focused on ways of improving the system which is often criticized for being bulky and heavy. In an attempt to solve some of these negative features, Wärtsilä has produced a Low Loss Concept (LLC) for DE installations that offers improved performance at lower cost. In the LLC system, the propulsion transformers are eliminated and replaced by one or two Low Loss Concept transformers in a central location. Wärtsilä LLC is available for low-voltage (690V) and medium-voltage (6600V) applications, covering power requirements of 5-70 MW. Resulting efficiencies can deliver significant fuel savings in the region of between $40,000 and $135,000 depending on the vessel size/type and operational profile. [More]
