MAN Energy Solutions Renamed Everllence

The former MAN Energy Solutions business is being rebranded as Everllence. Its large two-stroke engine portfolio is now presented under the Everllence B&W name.

Legacy engines, manuals, and spare parts may still carry MAN, MAN B&W, MAN Diesel & Turbo, or MAN Energy Solutions branding.

Ammonia Two-Stroke Engine Development

The Everllence B&W ME-LGIA ammonia engine completed major full-scale testing milestones, with first shipyard delivery planned for 2026.

The platform is designed for both newbuild and retrofit projects and can operate primarily on ammonia with a small pilot-fuel contribution.

Four-Stroke Ammonia Development

The AmmoniaMot 2 project is developing a medium-speed, four-stroke, dual-fuel ammonia test engine for future marine applications.

Most Powerful Methanol Engine

In 2025, MAN Energy Solutions announced an 82,440 kW 12G95ME-C-LGIM methanol engine, described at the time as the world’s most powerful methanol-fuelled two-stroke engine.

Four-Stroke Methanol Retrofit Development

Engineers are developing four-stroke methanol dual-fuel retrofit solutions for vessels such as cruise ships and ferries.

Expanded LNG and Methane Engine Range

New ME-GI methane engine variants were introduced on the 10.7 platform for container ships, tankers, bulk carriers, and car carriers.

Hybrid Marine Propulsion

MAN Engines continues to develop modular hybrid systems for yachts and workboats using inline six-cylinder, V8, and V12 diesel-engine platforms.
