Wärtsilä continues to advance the decarbonization of the marine industry with an order to supply a complete propulsion package for a 38,000 DWT methanol-ready cement carrier—the world’s largest of its kind and the first with a methanol-ready notation. The order was placed by NovaAlgoma, a joint venture between Switzerland-based Nova Marine Group and Canada’s Algoma Central Corporation. The vessel is being built at Zhejiang Xinle Shipbuilding Co., Ltd., with launch expected in late 2026. Wärtsilä booked the order in Q4 2024.
“This vessel aligns with our fleet development strategy to meet rising cement demand while reducing emissions,” said Vincenzo Romeo, CEO of Nova Marine Group. “As the largest and most eco-friendly cement carrier ever built, it marks a major step in our commitment to a green fleet. Wärtsilä’s expertise will ensure an effective transition toward decarbonization.”
Wärtsilä’s scope of supply includes two Wärtsilä 32 engines, one Wärtsilä 25 auxiliary engine, two gearboxes, two controllable pitch propellers, a tunnel thruster, three selective catalytic reduction (SCR) exhaust after-treatment systems, a propulsion control system, two shaft generators (PTO/PTI), and engine accessory items. Deliveries will begin in November 2025.
“Nova and Wärtsilä share a commitment to decarbonizing maritime operations,” said Roger Holm, President of Wärtsilä Marine & Executive Vice President of Wärtsilä Corporation. “This integrated package takes a holistic approach to efficiency, emissions reduction, and energy optimization.”
The Wärtsilä 32 engine is designed for high efficiency, easy maintenance, and long service intervals, with the flexibility to upgrade for methanol operation. The Wärtsilä 25 engine enhances modularity, fuel efficiency, and emissions reduction. Additionally, Wärtsilä’s propulsion solutions, including optimized gearboxes and larger propeller diameters, maximize efficiency and compliance with sustainability targets.
