The Low Loss Concept was developed by Wärtsilä to save both fuel and installation costs, as well as reducing emissions and the amount of space required for component installation. This innovation also delivers greater redundancy in the electrical propulsion system, and makes commissioning work easier.
The decision by Transport Desgagnés to opt for the LLC arrangement was reinforced by consultant Deltamarin Ltd, who found that the LLC was favorable over conventional power distribution solutions due to the high level of energy efficiency and redundancy it affords. The main electrical equipment components are divided into two separate compartments, a requirement deemed imperative to the shipowner's environmental considerations, and one that also increases redundancy.
The 381-passenger, 125TEU-carrying vessel will operate along the ecologically sensitive , with a weekly itinerary that takes in 22 ports-of-call with short ship stays of no more than five hours.
Wärtsilä's scope of supply to the Desgagnés-designed vessel includes a complete diesel-electric propulsion package based on four, nine-cylinder versions, of the established Wärtsilä 20CR (common-rail) medium speed generating sets. All 600V main distribution switchboards, the electric propulsion motors, and the frequency converters also form part of the supply agreement.
Wärtsilä will deliver the equipment to the Kraljevica Shipyard throughout January 2010.
