Everllence, the German engine manufacturer formerly known as MAN, has signed a memorandum of understanding (MoU) with Swiss electrification specialist ABB, and OceanWings, a French developer of wind-assisted propulsion systems (WAPS).
The MoU aims to jointly develop an optimised propulsion concept that builds upon Everllence’s and ABB’s existing DFE+ (diesel-electric with variable speed) concept, which enables high engine efficiency, even at partial loads; operational flexibility through multiple engines; and future integration of sustainable energy sources like batteries and fuel cells. The partners will initially focus on LNG carriers.
Dominik Thoma, global manager of LNG cargo at Everllence, said: “While WAPS introduces highly variable propulsion demand due to fluctuating wind conditions, DFE+ propulsion offers precise load control and operational flexibility, making it exceptionally well-suited to harness the variable and intermittent power contributions of wind-assisted systems. In combination with smart power-management systems and adaptive trimming, we see significant potential for reduced emissions and opex.”
