Wärtsilä will supply a hybrid-electric propulsion system for an 11,000 dwt Limestone Carrier contracted by Montreal-based CSL Group (CSL) with CCCC Shanghai Equipment Engineering and Jingjiang Nanyang Shipbuilding.

The Limestone Carrier, when delivered in 2026, will be the world’s first fully electric battery-capable self-unloading vessel. It will initially run on a hybrid diesel and battery system, with 50% of total battery capacity installed replacing diesel with electric power. By 2031, the aim is to run the ship entirely on electric power, further reducing carbon emissions to less than 10%.

For this vessel, Wärtsilä will supply the whole hybrid electric propulsion system, including generators, DC hub, energy and power management system, main propulsion e-motors, bow thruster e-motors, and the battery solution. Delivery is scheduled for early 2025.
