MAN Energy Solutions will deliver its MAN B&W 12G95ME-C10.5-Liquid Gas Injection Methanol engine for 12 new container vessels next month.
MAN Energy Solutions is delivering what the company is calling “the world's most powerful two-stroke methanol engine”—MAN B&W 12G95ME-C10.5-Liquid Gas Injection Methanol (LGIM)—next month. The engine is rated at 82,440 kW at 80 RPM.
“At MAN Energy Solutions, our vision of 'Moving Big Things to Zero' motivates everything we do in developing the engine technology to operate on those fuels vying for prominence in the future market,” said Bjarne Foldager, Head of Two-Stroke Business at MAN Energy Solutions. “This latest milestone is just the latest fulfillment of that. By harnessing the potential of methanol, we are bringing the maritime industry closer to zero-emission solutions, and we fully expect methanol to figure prominently as a future fuel across all segments.”
The engine, being built by Chinese licensee CSSC-MES Diesel Co., Ltd., is the first of 12 bound for a series of 12 × 24,000 20-foot equivalent unit container vessels currently under construction:
Each engine will also feature MAN Energy Solutions’ exhaust gas recirculation (EGR) turbocharger emissions system.
“As we move toward a multi-fuel future, interest in methanol has grown steadily,” said Christian Ludwig, Head of Two-Stroke Sales and Promotion at MAN Energy Solutions. “To date, between newbuild engines and retrofits, we have won over 230 ME-LGIM references that have accumulated over 600,000 hours running on methanol alone. With ME-LGIM technology reaching 10 years in the market, it represents mature, proven technology and reflects MAN Energy Solutions’ ability to develop attractive technology to enable shipping’s carbon transition. Furthermore, while methanol produced from renewable sources is an attractive marine-fuel option due to its low carbon intensity, an engine using green methanol can even provide carbon-neutral propulsion, adding to the benefits the ME-LGIM brings to the table.”

MAN Energy Solutions also announced that it will deliver four shipsets to the Wenchong shipyard in China, each consisting of three MAN 8L21/31 MK2 generator sets. These will be installed on four Construction and Commissioning Service Operation Vessels operated by German Offshore Shipping. CMP, an official licensee, will manufacture the engines in China, and delivery is expected in Q1 2027. The order includes options for additional C-CSOVs.
These engines will be delivered in a diesel-electric propulsion configuration, with part-load optimization to enhance fuel efficiency. The diesel-electric concept aligns with the dynamic positioning Stage 2 system set by Det Norske Veritas, which outlines backup systems, components, and redundancy options to prevent loss during faults.
“We are experiencing increased demand for efficient, competitive engine designs for the offshore wind segment, which our portfolio of small-bore propulsion engines is fulfilling, backed up by our MAN PrimeServ after-sales network,” said Hakon Juel Hansen, Manager Engine Promotion & Business Development, MAN Energy Solutions. “With these technically sophisticated offshore vessels, DO is showcasing the adaptability of our engine portfolio.”
