ABB to Supply Onboard DC Grid to Shipowner

Power and automation technology group ABB has won an order from ship owner Myklebusthaug Management to supply the first direct current power grid on board a ship, in an installation ABB says should reduce fuel consumption and emissions by up to 20 percent.

The OnBoard DC Grid will allow an offshore platform support vessel, under construction in Norway, to operate at the highest energy efficiency level to minimize emissions, ABB says.

In traditional electrical propulsion vessels, multiple DC connections are made to thrusters and propulsion drives from an alternating current circuit, accounting for more than 80 percent of electrical power consumption. ABB’s Onboard DC Grid saves energy by distributing power through a single DC circuit.

The company will provide its full onboard DC system including all power, propulsion and automation systems for the 93-meter long, 5,000-ton multi-purpose oil field supply and construction vessel, which is scheduled for delivery in the first quarter of 2013.

In January, Viking Line said that one of its future cruise ferries will employ ABB software to manage its energy use. STX Finland is building the liquefied natural gas-fueled NB 1376 at its Turku, Finland shipyard, and will deliver the ferry to Viking Line in 2013.
