BACKGROUND • Joint project with WE Tech Solutions for a permanent magnet shaft generator and WE Drive™ • MS Viikki – the world’s first LNG-fueled bulk carrier • Owned by Finnish-based ESL Shipping • Year built: 2018 • Shipyard: Sinotrans & CSC, Jinling Shipyard, China • Cargo capacity: > 33, 000 m 3 © 2018 YASKAWA CONFIDENTIAL INFORMATION ALL RIGHTS RESERVED October 17, 2021 | 2

CHALLENGE • Baltic Sea and the Gulf of Bothnia have significant winter ice coverage, and protected as a sulfur emission control area (SECA) • Sailing in ice conditions is considered to be the most demanding – ice can cause rapid changes in the main engine load • The propulsion units need to be flexible, responsive and deliver optimal power per unit, while meeting the most stringent environmental criteria © 2018 YASKAWA CONFIDENTIAL INFORMATION ALL RIGHTS RESERVED October 17, 2021 | 3

SOLUTION • The solution is built around WE Tech’s variable frequency drive technology WE Drive™ and The Switch PMM 1000 direct-drive permanent magnet shaft generator • Mechanical energy from the propeller shaft is captured and converted to green electrical energy for the vessel • The PMM generates energy for vessel systems, allowing less waste and increased efficiency • The solution offers different operational modes, such as Power Take In (PTI) according to needs © 2018 YASKAWA CONFIDENTIAL INFORMATION ALL RIGHTS RESERVED October 17, 2021 | 4

RESULTS • MS Viikki – the world’s most environmentally friendly bulk carrier • Designed in accordance with EEDI • The solution allows MS Viikki to achieve Ice Class 1 A and cut fuel consumption by 50% since 2006 • ESL Shipping gains improved profitability and competitiveness • Leaving the Chinese yard, MS Viikki made its way to Finland via the Northeast Passage. This shortened the journey by 3 weeks, compared to routing via the Panama Canal, and cut emissions by 40% © 2018 YASKAWA CONFIDENTIAL INFORMATION ALL RIGHTS RESERVED October 17, 2021 | 5
