At GasTech 2025 in Milan, Everllence signed a Memorandum of Understanding (MoU) with ABB and OceanWings to jointly develop an optimized propulsion concept that builds upon Everllence’s and ABB’s existing DFE+ (Diesel-Electric with variable speed) concept.
The concept 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.
With growing regulatory and financial pressure to reduce emissions and the technological maturity of wind-assisted propulsion systems (WAPS), the partners aim to showcase the benefits of combining WAPS with DFE+.
OceanWings’ wingsail technology features an Adaptive Trimming capability, which continuously optimizes sail positioning by accounting for each vessel’s unique aerodynamic profile and all aerodynamic interactions.
The partners aim to initially target LNG carriers. Romain Grandsart, COO of OceanWings, said: “LNG carriers sail fast and spend typically 70% of their time at sea. This is ideal for harnessing wind and the full potential of OceanWings rigid wingsails. Combined with optimized propulsion, including a DFE+ highly efficient variable-speed concept engine, this unlocks high double-digit fuel savings and greenhouse-gas emissions reduction.”
Rune Lysebo, Head of Strategic Market Development, ABB’s Marine and Ports division, said: “We at ABB believe that the
