CSL laker vessel features Berg Propulsion's diesel-electric drive train

“This can be overly complex and hard to maintain, while energy is lost at every step. The direct-drive electric solution features electric motors that are integrated to directly drive the propeller shaft.”

“For Nukumi, the use of direct-drive electric propulsion shows the value available when a shipowner, an equipment maker and a system integrator work together in the early ship design phase on prioritising performance and sustainability. This is a key reference for direct-drive electric as a fuel efficient and easy to install technology which broadens the appeal of greener electric propulsion.”

The removal of gears allows for shorter shaft lines, fewer bearings and a smaller engineroom footprint, while very high torque meant the same power could drive larger propellers, added Mr Nyberg.

Direct-drive electric is future-proofed to accommodate alternative energy sources, using a DC hub or ‘superdrive’ to draw on main engines or stored energy from zero-emissions batteries and fuel cells, as required.

CSL vice-president, global technical services, Frederic Jauvin said Nukumi’s combination of optimised hull form, electric propulsion technology and Tier III diesel-electric engines will help cut greenhouse gases by 25% and other pollutants by 80% in comparison with its predecessor vessels.

“Nukumi charts new waters when it comes to safe, sustainable and efficient shipping in the Gulf of St Lawrence and Great Lakes region,” said Mr Jauvin.
