2. 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 m3

3. 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

4. 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

5. 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 1A 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%
The demanding conditions of rough seas – not an issue.
