First ship with system of distribution in continuous current
"Dina Star", delivered to the Myklebusthaug shipowner from the Kleven Yard, is equipped with the system supplied from ABB
April 11, 2013
Yesterday Dina Star, the of edge (On Board DC Grid), is delivered to the Norwegian shipowner Myklebusthaug from the Kleven Yard. The system electrical worker, supplied from group ABB, will afford to the ship to operate to the highest regimes than efficiency reducing to the maximum the emissions.
The ship from support for operations in platform (PSV) Dina Star, planned from the Norwegian company Marin Teknikk, is long 93 meters with a gross capacity of about 5.000 tons and will be a multifunctional unit, that is it will be used is for the oil transport that as ship from support constructions in the Seas of the North.
ABB has supplied the system of edge in continuous current with all the systems of power, propulsion, automation and advisory. The Helvetic group has remembered that in the ships to propulsion traditional electrical worker the multiple connections in continuous current are managed through the drives of the system of propulsion from a circuit alternating current (AC), in charge of about 80% of electric power consumption, while the system of edge in continuous current of ABB - it has emphasized the group - ahead represents an enormous step for the naval industry because the power improves the propulsion distributing, through a single circuit in continuous current, affording a remarkable saving on the edge consumption. For the moment the range DC is available in lowland tension with power installed until about 20 megawatt. Distributing electricity in continuous current, the system does so as that the generators operate consequently to a variable speed and to optimal the specific fuel consumption. This - it has found ABB - is a particularly important benefit for the ships offshore that operate in modality DP (Dynamic Positioning), where the necessities of medium consumption are lowlands. The configuration in continuous current moreover does so as that the cumbersome switches for alternating current neither the transformers of propulsion are not more necessary neither. All this, joined to a very flexible layout, for transport increases the space available on the ship.
