Dalian Marine Diesel delivered a methanol dual-fuel, low-speed main engine following inspection and certification by China Classification Society.
Rated at 32,970 kW and capable of 72 rpm, the engine complies with IMO Tier II emission limits and will serve as the propulsion heart of the world’s first methanol-powered, smart very large crude carrier, now under construction at Dalian Shipbuilding Industry Co. for Haihong Shipping.
CCS’s Dalian Branch supported every stage from R&D to manufacturing and sea-trial testing—drawing on its deep expertise in low-speed diesel verification.
Surveyors refined test protocols to cover methanol-diesel dual-mode running, seamless fuel switching, and performance under extreme conditions, ensuring rigorous quality control and a flawless hand-over of the engine.
The project underscores CCS’s growing role in advancing green shipping technologies.
The society plans to expand its work in R&D, inspection, and certification of low- and zero-carbon marine power systems, collaborating across the supply chain to accelerate the industry’s transition to cleaner propulsion.
