MAN Energy Solutions has engineered the world’s most powerful two-stroke methanol engine, delivering a groundbreaking 82,440 kW at 80 rpm. The cutting-edge engine is currently in production by the Chinese licensee CSSC-MES Diesel and is set to power a fleet of twelve 24,000 TEU container vessels now under construction.
Seven of these vessels are being built at Nantong COSCO KHI Ship Engineering for Orient Overseas Container Line, while five are underway at Dalian COSCO KHI Ship Engineering for COSCO Shipping Lines. MAN Energy Solutions plans to deliver the first engine by June 2025.
Each engine incorporates MAN’s advanced exhaust gas recirculation (EGR) turbocharger cutout system—the largest two-string EGR configuration ever installed on a two-stroke engine—significantly reducing emissions.
“By harnessing methanol’s potential, we are propelling the maritime industry closer to zero-emission solutions,” said Bjarne Foldager, head of MAN’s two-stroke business. “We firmly believe methanol will be a pivotal future fuel across all shipping segments.”
With over 600,000 operating hours accumulated on MAN engines running solely on methanol—across both new builds and retrofits—the company’s experience is extensive.
“As the industry transitions toward multi-fuel capabilities, methanol’s appeal continues to grow,” added Christian Ludwig, head of two-stroke sales and promotion. “Green methanol, produced from renewable sources, presents a compelling low-carbon marine fuel option, offering the potential for truly carbon-neutral propulsion.”
MAN Energy Solutions’ breakthrough underscores its commitment to sustainable shipping and positions methanol as a cornerstone fuel in the maritime sector’s decarbonization journey.
