LNG-fuelled tanker sails smoothly

WE Tech Solutions (WE Tech) and The Switch have announced that a Terntank Rederi AS chemical/product tanker featuring their direct-drive permanent magnet shaft generator solution was recently delivered from the Chinese AVIC Dingheng Shipyard.

The LNG-fuelled Ternsund is the first in a line of four Terntank Rederi AS chemical/product tankers destined for the Baltic Sea. When building this vessel, Terntank’s goal was to use a new standard in environmentally friendly technology that enables the shipowner to cut emissions to a new level. As such, the company selected WE Tech’s energy efficient shaft generator solution.

The delivery of Terntank’s second vessel, Ternfjord, has been planned for 12 September 2016, following the successful completion of its sea trials. The final two ships will be delivered in October 2016 and January 2017.

The WE Drive™ 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.

With the WE Drive™ and the direct-drive permanent magnet shaft generator in Power Take Out (PTO) mode, the available power for the vessel’s electrical network is up to 780 kW, generated by a fuel-efficient two-stroke, low-pressure, dual-fuel main engine. In this mode, the auxiliary generators are not running. In Power Take In (PTI) mode, the WE Drive™ converts auxiliary generator power to propulsion power by employing the direct-drive permanent magnet shaft generator as a motor, with a maximum rated output of 1000 kW.

Mika Koli, Business Development Manager from The Switch, added: “The market has now recognised that a PM shaft generator is the most energy-efficient way to generate power in a vessel.”

The Switch PMM 1000 shaft generator is installed directly on the propeller line and allows very high energy efficiency, especially in part loads.
