Technology group Wärtsilä has been contracted to provide a hybrid-electric propulsion system for an 11,000 dwt Limestone Carrier, commissioned by Montreal-based CSL Group in collaboration with CCCC Shanghai Equipment Engineering and Jingjiang Nanyang Shipbuilding. The order, valued and finalized in Q1 2024, underscores CSL’s commitment to enhancing its emissions profile as part of a broad decarbonisation strategy.
Wärtsilä’s role involves the development of a bespoke hybrid-electric propulsion system designed to optimize engine and battery performance tailored to the vessel’s operational needs. This system aims to enhance safety through operational redundancy in confined waters, while also boosting efficiency and lowering fuel consumption.
Frédéric Jauvin, Vice-President of Global Technical Services at CSL, commented on the decision: “We require an electrically integrated hybrid-powered propulsion solution from a single-source supplier capable of providing lifecycle support. Wärtsilä was selected for our newbuild project because of their proven ability, experience, and track record in delivering high-quality electrification and hybridisation systems.”
Upon delivery in 2026, the Limestone Carrier will be the world’s first fully electric battery-capable self-unloading vessel. Initially, it will operate on a hybrid diesel and battery system, featuring 50% of its total battery capacity to replace diesel power with electric power. CSL aims to transition to full electric operation by 2031, further reducing carbon emissions to less than 10%.
Torsten Büssow, Director of Electrical & Power Systems Business at Wärtsilä Marine, highlighted the importance of the project: “Wärtsilä is committed to making decarbonised shipping possible, so we are delighted to be supporting CSL with solutions that enhance the sustainability of their fleet. This short sea shipping vessel will experience a lot of manoeuvring and variable load profiles, and electrification and hybridisation systems are the most efficient for such vessels.”
For this project, Wärtsilä will deliver a comprehensive hybrid electric propulsion system, including generators, a DC hub, Energy and Power Management System, main propulsion e-motors, bow thruster e-motors, and the battery solution. Delivery of the system is scheduled for early 2025.
