Looking for a reliable two-stroke engine solution for fuel oil operation?
Our global network of engine specialists is here to support you. Whether you’re planning a newbuilding project or upgrading an existing vessel, we’ll help you identify the best-fit engine configuration for your specific requirements. With thousands of engines in operation worldwide, our two-stroke engines are known for their long service life, high thermal efficiency, and operational reliability across all major vessel segments.

Modular design for long-term adaptability
The ME-C engine features a modular design that makes it particularly suitable for upgrading. This design enables shipowners to future-proof their vessels for evolving economic and regulatory conditions – for example, by adding dual-fuel capability for methanol.
As the only two stroke engine designer in the world, we have successfully completed retrofit projects to dual-fuel operation, and we now have an ammonia retrofit option in development as well. With these proof points, the ME-C engine has a proven track record as a platform that evolves with market and environmental demands.
The ability to convert an existing ME-C engine to operate on alternative fuels such as methanol, methane, LPG or ethane gives ship operators valuable fuel flexibility and a pathway to decarbonization.

B&W ammonia engine development
Everllence is aiming to deliver the first ammonia engine, the Everllence B&W ME-LGIA, to a shipyard in 2025. It will be available as newbuild or retrofit.

B&W ME-GI
The ME-GI engine impresses with extremely lowest methane slip and very high fuel efficiency. It is the most environmentally friendly methane-fuelled engine on the market. By the optional use of fuel oil or LNG/bio-methane/SNG, it represents a highly efficient, flexible, propulsion-plant solution.
- Engine speed: rpm to 56 – 167
- Output: 4,350 – 82,440 kW at L1

The technology of the ME-GIE is based on our successful ME-GI engine. This engine can be operated with liquefied ethane gas (LEG) as well as fuel oil – which makes it the standard choice for ethane carriers. This engine offers very competitive fuel oil and gas consumption, plus operational stability and efficiency due to the diesel principle.
- Engine speed: 72 – 100 rpm
- Output: 8,600 – 21,440 kW at L1

Our ME-LGIM is a dual-fuel engine characterized by its high efficiency and capability of operating on methanol. With a proven record of more than 600,000 operating hours on methanol alone, the engine concept provides a high degree of reliability. When fuelled by green methanol, our ME-LGIM engine can offer truly carbon-neutral propulsion, while reducing sulfur and particle matter emissions significantly at the same time.
- Engine speed: 56 – 125 rpm
- Output: 6,950 – 82,440 kW at L1

B&W ME-LGIP
Our ME-LGIP is the only two-stroke dual-fuel engine on the market which can be fuelled with LPG. The low operational costs as well as the simple retrofit solution are particularly convincing.
- Engine speed: 72 –103 rpm
- Output: 8,600 – 22,720 kW at L1
Proven performance, tailored to your operation
Fuel efficiency and reliability are at the core of the ME-C engine’s performance promise. The range includes engines with outputs from 4,350 to 82,440 kW, bore sizes from 35 to 95 cm, and 5 to 12 cylinders – with speeds ranging from 56 to 167 rpm.
All ME-C engines feature fully integrated electronic control systems that deliver the required fuel injection pressure and rate shaping at any load condition. Recent innovations, such as the introduction of the G50 10.7 variant, reflect our ongoing efforts to reduce fuel consumption and emissions across all engine configurations.
Optimize your investment at every stage
Smart investment decisions require both long-term flexibility and reliable performance from day one. The ME-C engine is designed to support your business case – from initial CAPEX planning to optimized OPEX and future-ready retrofit options.

Invest in what you need
From a CAPEX perspective, the ME-C engine offers a scalable solution tailored to your vessel’s requirements. With its modular design and proven platform, you only invest in what you need today – while keeping the flexibility to adapt to future demands. Thanks to its established retrofitability, the ME-C engine protects long-term asset value and ensures a smooth upgrade path when fuel strategies or regulatory frameworks evolve.
Maximize your profitability
Operationally, the ME-C engine is built for low OPEX. It can be fine-tuned to deliver industry-leading thermal efficiency helping to reduce fuel consumption, lube oil use, and emissions across a wide range of operating conditions. Especially in volatile fuel markets with fluctuating fuel prices, the ME-C engine gives operators a critical edge in managing long-term profitability.


Retrofit with confidence
Retrofit solutions from Everllence PrimeServ make it easy to extend the lifecycle and upgrade the capabilities of your ME-C engine. Whether converting to dual-fuel operation or implementing performance-enhancing modifications, every solution is engineered to safeguard engine integrity and align with your operational goals. The result: flexible, future-ready propulsion.Learn more about our two-stroke dual-fuel retrofit solutions
