Everllence B&W ME-LGIM engine: a proven solution for sustainable maritime propulsion 

Since 2016, the Everllence B&W ME-LGIM engines have accumulated over 600,000 running hours on methanol alone. As global shipping moves toward more sustainable operations, the ME-LGIM engine plays a vital role in enabling a scalable energy transition. This is particularly important as methanol produced from renewable sources becomes more widely available, contributing to low-emission operation due to its low carbon intensity. This engine type is available either for newbuilds or for retrofitting of exiting vessels.

When powered by green methanol, the Everllence B&W ME-LGIM offers significant environmental benefits and can even provide carbon-neutral propulsion. It helps reduce greenhouse gas (GHG) emissions, particulate matter, and sulphur oxides (SOₓ), making it a clean and compliant solution that aligns with global climate goals and emission regulations. 

 

Global aftersales network and digital performance monitoring

To ensure reliability and global service availability, all ME-LGIM engines are supported by the worldwide Everllence PrimeServ network. This ensures maintenance, technical support, and access to OEM spare parts over the entire engine lifecycle. 

Additionally, the ME-LGIM is connectivity-ready and can easily be integrated with our digital solutions such as Everllence PrimeServ Assist. These services enable advanced performance monitoring, diagnostics, and remote support – helping to optimize operation, minimize downtime, and extend engine life.

Key benefits of the ME-LGIM engine

Efficiency

The engine is optimized for methanol fuel operations by tuning methods. This supports a very high efficiency. Seamless switching between methanol and fuel oil ensures consistent performance and uninterrupted vessel operation – supporting fuel flexibility without compromising reliability. 

Scalability

Methanol’s main advantage as an alternative fuel lies in its easy storage and handling. As a liquid at ambient temperatures and pressures, methanol significantly simplifies port-side infrastructure and bunkering on board. While its production as a green fuel is still limited, its handling costs are low, reducing the complexity of storage and bunkering infrastructure at ports. As such, carbon-neutral methanol can be used whenever it is available at scale. 

Versatility

Thanks to an extensive ME-LGIM engine portfolio, this methanol-capable two-stroke solution supports a wide range of vessel types. The Everllence methanol-fuelled two-stroke engine is ideally suited for container vessels of all sizes, product tankers, VLCCs, RoRos, PCTCs, and various bulk carrier configurations. It offers full dual-fuel functionality, operating on both methanol and conventional marine fuels. 

The Everllence B&W ME-LGIM engine is available for newbuilding projects and retrofits.

The ME-LGIP is generally available for retrofits as well as newbuilds. Whether it makes sense to upgrade existing vessels with the ME-LGIP engine depends on different factors. The decision to proceed with an upgrade is based on technical feasibility and the overall cost-effectiveness of the conversion. 
Cost-wise, LPG is a better option than compliant fuel-oil with high lifetime-savings prospects. By leveraging LPG as a marine fuel, vessels benefit from savings due to lower fuel consumption and full dual-fuel flexibility, which guards against price sensitivity to post-2020 fuel-price fluctuations. Furthermore, the ability to use LPG cargo as a supplemental fuel source also reduces time and fees for fuel bunkering.

Harnessing LPG propulsion also translates into cleaner, more efficient engines that are cheaper to maintain. In addition, the fuel flexibility of dual-fuel engines ensures full redundancy for uninterrupted operations.

Compared to 2020-compliant fuels, using LPG as a fuel would reduce: SOx by 99%, CO2 by 15%, NOx by 10%, and particulate matter by 90%.

LPG-fuelled engines like the Everllence B&W ME-LGIP engine are ideally suited for a the application on LPG carriers and shuttle tankers . Thanks to their fuel flexibility and environmental benefits, ME-LGIP engines are an attractive choice for both newbuilds and retrofits.
