The Permanent Magnet Shaft Generator technology features active front-end low harmonic drive technology

WE Tech Solutions Oy is to supply two Permanent Magnet Shaft Generator solutions, including an efficient DC-link power distribution, for a series of 9,400-tonne asphalt/bitumen tankers owned by Tarbit Shipping AB.

The WE Drive™ and the Permanent Magnet Shaft Generator technology features active front-end low harmonic drive technology, said to allow the shaft generator to operate over the full main engine speed range while generating electricity for the vessel’s electrical network with high efficiency over the entire range. This feature is particularly prominent in electrical part loads – the normal electrical load condition in any ship.

WE Tech is also to deliver its efficient power distribution solution with a WE Drive™ and a Permanent Magnet Shaft Generator that can provide the vessel’s electrical network with up to 1,000 kW electrical power in Power Take Out (PTO) mode.

The WE Drive™ offers two Power Take In (PTI) modes: the first PTI mode can provide 820 kW auxiliary power to boost the main engine in demanding situations. The second PTI mode is for Take-Me-Home: the WE Drive™ is used as an auxiliary propulsion drive when the main engine is out of operation.

In addition, WE Tech says the solution uses the common DC-link of the WE Drive™ technology to enable energy efficient DC power distribution for larger electrical consumers such as the bow thruster and cargo pumps.

WE Tech's solutions will also be delivered to China's Tianjin Xingang Shipbuilding Heavy Industry Co Ltd for a series of four newbuild vessels owned by Wallenius Shipping; to China's AVIC Dingheng Shipbuilding Co Ltd for a series of four newbuilds owned by Terntank Rederi AS; to Turkey's Besiktas Shipyard for two newbuilds owned by Transport Desgagnes; and to China’s Jiangsu Hantong Ship Heavy Industry Co Ltd for a two new vessels owned by Vulica Shipping.

Delivery is scheduled for June 2016.
