WE Tech order from Wartsila Finland Oy

In June 2014, WE Tech Solutions Oy and Wärtsilä Finland Oy signed a contract for the delivery of four Direct Drive Permanent Magnet Shaft Generator solutions to a series of LNG fueled tankers. WE Tech is a leading energy efficiency solution provider for the shipping industry. Wärtsilä Finland Oy is a global leader in complete lifecycle power solutions for the marine and energy markets.

Based in Vaasa, Finland, WE Tech is to deliver its Direct Drive Permanent Magnet Shaft Generator solution to a series of four LNG powered 15,000 DWT product tankers ordered by Terntank Rederi AS in Denmark. The tankers will be built by the Chinese shipyard Avic Dingheng Shipbuilding Co., Ltd. Contract signing took place on June 19, 2014 between WE Tech and Wärtsilä. Equipment delivery will commence in April, 2015.

Terntank aims to have the most energy efficient and environmentally adapted tankers. Using LNG as fuel will achieve significant environmental advantages. With the WE DriveTM and the Direct Drive Permanent Magnet Shaft Generator technology from WE Tech, the energy efficiency of the machinery reaches unprecedented levels in the marine industry. With its active front-end low harmonic drive technology, the 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.

With the WE DriveTM and Direct Drive Permanent Magnet Shaft Generator in Power Take Out (PTO) mode, the available power for the vessel’s electrical network is up to 600 kW, generated by a fuel efficient 2-stroke, low pressure, dual-fuel main engine. In this mode the auxiliary generators are not running. As the operating hours of the auxiliary generators are drastically reduced, significant savings are achieved. Reduced running hours also decrease the need for maintenance.
