WE Tech Solutions (WE Tech), a leading energy efficiency solution provider, has confirmed an order to deliver Direct Drive Permanent Magnet Shaft Generator solutions to a series of two new 17500 dwt IMO class II chemical tankers. The order was placed by the Chinese shipyard Taizhou Kouan Shipbuilding Co., Ltd. on July 25, 2016. The vessels are owned by Bergen-based Norwegian shipowner Rederiet Stenersen AS.
With the active front-end low harmonic drive technology and the Permanent Magnet Shaft Generator technology in our solution, the energy efficiency of the machinery reaches unmatched levels in the marine industry. WE DriveTM allows 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 to deliver its Efficient Power Distribution solution with a WE DriveTM and a Direct Drive Permanent Magnet Shaft Generator that can provide the vessel’s electrical network with up to 1500 kW electrical power in Power Take Out (PTO) mode. Significant savings can be achieved by drastically decreasing the operating hours of auxiliary generators, as well as reducing the need for maintenance.
The solution also offers the Power Take In (PTI) mode for Take-Me-Home: the WE DriveTM is used as an auxiliary propulsion drive when the Main Engine is out of operation. It converts auxiliary generator power to propulsion power by employing the Direct Drive Permanent Magnet Shaft Generator as an electrical motor. Furthermore the solution utilises the common DC-link of the WE DriveTM technology to enable energy efficient DC power distribution for the bow thruster.
The delivery from WE Tech to the first vessel is scheduled in quarter two of year 2017. WE Tech creates savings for the shipping industry by delivering energy efficient solutions to vessels around the world.
