Wärtsilä secures first ferry reference for it...
Wärtsilä Corporation, Trade & Technical Press Release, 23 October
2008
Wärtsilä's Low Loss Concept system has been ordered by Canadian
shipowner Transport Desgagnés for installation in a 95m
passenger/vehicle/container vessel, to be built at Croatia's
Kraljevica Shipyard. It will be the first ever application of the Low
Loss Concept (LLC) in a passenger vessel.
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. It has already established
considerable support from owners in the offshore vessel segment.
"In a conventional diesel-electric propulsion arrangement, you need
many large distribution transformers. But we have developed a system
that obviates the need for transformers in the propulsion line, so we
can eliminate these huge, heavy components, and their associated
equipment and utilities. This reduces investment costs, operational
costs, and the space required for the equipment onboard," says Piotr
Kabacinski, Project Manager, Wärtsilä Ship Power.
Fuel savings, less pollution
"LLC can reduce electrical losses by 3%, and this means good fuel
savings and less pollution. The system also provides improved health,
safety and environmental (HSE) performance through fewer components,
lower pollution and higher system redundancy," adds Mr Kabacinski.
The decision by Transport Desgagnés to opt for the LLC arrangement
was reinforced by consultant Deltamarin Ltd, who found that the LLC
was favourable 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.
Additionally, the total installed equipment weight and required space
of the LLC package was found to be significantly less than that
offered by competitors.
These were very important factors in the equipment selection, as the
381-passenger, 125TEU-carrying vessel will operate along the
ecologically sensitive St Lawrence River, with a weekly itinerary
that takes in 22 ports-of-call with short ship stays of no more than
five hours.
"LLC combined with the smokeless operation of common-rail engines
offers significant benefits to any shipowner operating in
environmentally sensitive areas," says Kabacinski.
In addition to the state-of-the-art LLC system, 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.
