WE Tech Solutions has received an order to deliver its direct-drive permanent magnet shaft generator solution to two new 25 600 DWT dual-fuelled handysize bulk carriers, with an option for two more. The Switch will deliver the PM shaft generators. The vessels are owned by the Finnish ship owner ESL Shipping Ltd. The ship owner chose PM shaft generator technology to support its sustainability strategy and start a new era in green shipping within pollution-sensitive seaways.

These new, ice-class 1A ships will be the first LNG dual-fuelled bulk carriers in the world, representing the latest in technology and innovation. The aim of these new-build vessels is to raise the bar when it comes to energy efficiency and sustainability.

“With the active front-end low harmonic drive technology (WE Drive™) and the permanent magnet shaft generator technology in our solution, the energy efficiency of the machinery reaches unmatched levels in the marine industry,” said Martin Andtfolk, Sales Manager of WE Tech.

Using the Power Take Out (PTO) mode, WE Drive™ enables propulsion machinery to operate in combinator/variable speed while the direct-drive permanent magnet shaft generator produces electrical power up to 700 KW for the vessel’s electrical network. Using the Power Take In (PTI) mode, WE Drive™ converts auxiliary generator power to propulsion power by employing the direct-drive permanent magnet shaft generator as an electrical motor. 

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

The choice of The Switch PMM 1000 shaft generator, the most common type delivered to date, is very suitable for this type of bulk carrier vessel. It is installed directly on the propeller line and allows extremely high energy efficiency, especially in part loads.

The delivery from WE Tech is scheduled for March 2017.

"Our vision is 30% less fuel consumed in the global shipping industry by 2030,” says Mårten Storbacka, Managing Director of WE Tech. “This is a perfect example of implementing advanced drive train solutions for green shipping. ESL’s goal of operating extremely energy-efficient LNG-fuelled bulk carrier vessels is further supported by the choice of The Switch PM shaft generator.”
