Everllence (as MAN Energy Solutions is now known) has announced the first order for its 175DF-M (dual-fuel methanol) high speed engine.
The order is for two 12V175DF-M and one 16V175DF-M variable speed genset engines, destined for a superyacht currently under construction by an undisclosed European shipyard with delivery scheduled for July 2027. The order includes the methanol fuel supply systems.
The company reports that many customers from the ferry, cruise, offshore, tug, superyacht and governmental segments have shown a strong interest in the 175DF-M engine since it began development in 2023. Everllence has been working with various customers on concrete vessel concepts – both on newbuilds that are methanol-capable on delivery, and on methanol-ready concepts that allow future conversion of current ship designs via a retrofit scenario.
Dr Alexander Knafl, Head of R&D, Four-Stroke, Everllence, said: “We are happy to announce that a leading superyacht builder has selected the 175 dual-fuel methanol engine as its latest project. The engine features very high methanol-combustion efficiency, low emissions and super-high reliability. We are furthermore proud to be able to say that this is a first order for a high-speed dual-fuel methanol engine dedicated to diesel-electric and mechanical propulsion.”
Florian Keiler, Head of High-Speed Sales, Marine Four-Stroke, Everllence, added: “The customer’s decision to order three 175DF-M variable-speed gensets for a methanol-diesel-electric propulsion setup reflects its strong confidence in our methanol engine technology. The combination of advanced performance, future-proof design, and Everllence’s clear commitment to sustainable shipping – embodied in our mission, ‘Moving big things to Zero’ – was key to this milestone. We are convinced that the 175DF-M will play a pivotal role across a wide range of marine applications powered by carbon-neutral fuels.”
In keeping with the company’s development and market introduction of two-stroke and four-stroke medium-speed dual-fuel methanol engines, Everllence began the development of the high-speed 175DF-M engine in 2023, expanding its future-fuel four-stroke portfolio. Based on computational simulations and the optimisation of the combustion process on the test bed, the 175DF-M is expected to achieve never-before-seen methanol-shares in combination with a high power-density and high fuel-efficiency.
