WE Tech to deliver shaft generator solutions to Stena’s new highly fuel efficient ROPAX ferries

WE Tech Solutions Oy has received a significant order to deliver its energy efficient permanent magnet shaft generator solutions to a series of four ROPAX ferries, with an option for another four. The vessels are to be built for the Swedish shipping company Stena RoRo at AVIC Weihai Shipyard Co., Ltd. in China. The four initial vessels will be operated by Stena Line within its route network in Northern Europe.

A prestigious order for WE Tech
“WE have developed the most energy efficient shaft generator solution to reduce the fuel consumption, operational costs and environmental footprint. Cooperation with one of the pioneers in shipping – Stena RoRo is a very significant step for us”, says Martin Andtfolk, Sales Manager of WE Tech.

The most fuel-efficient ferries in the world
“These ships will be the most fuel-efficient ferries in the world and will set a new industry standard when it comes to operational performance, emissions and cost competitiveness, positioning Stena Line to support its customers in the next decades”, says Mr Carl-Johan Hagman, Head of Shipping, Stena AB.

Tons of fuel savings every day
“With our solution the shaft generator, driven by the main engine, can produce all the needed electricity on-board without using any fuel to run the auxiliary generators when sailing. Our solution is also based on frequency drive technology which allows the main engine to run at variable speed while producing electricity on-board. This results in tons of fuel savings every day”, says Mr Andtfolk. The two 2600 kW shaft generators, together with variable frequency drive – WE Drive™, generate power for the ship’s electrical network in power take out (PTO) mode. The solution also utilises the common DC-link for power distribution in bow thrusters.

”With our proven technology, we take our customers to success in terms of energy efficiency, fuel consumption and green values”, says Mr Mårten Storbacka, Managing Director of WE Tech. The equipment delivery from WE Tech to the first vessel is scheduled in January 2018.
