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.

Low methane slip emissions

Everllence
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 optimal choice for ethane carriers

Everllence B&W ME-GIE

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

Scalable energy transition

Everllence B&W ME-LGIM

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

Optimal choice for LPG carriers

Everllence
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.
