At GasTech 2025 in Milan, Everllence entered into a Memorandum of Understanding (MoU) with ABB, a leader in electrification and automation, and OceanWings, renowned for wind-assisted propulsion systems. This collaboration aims to develop an optimized propulsion concept that enhances Everllence’s and ABB’s existing Diesel-Electric with variable speed (DFE+) technology. The focus is on achieving high engine efficiency at partial loads, operational flexibility through multiple engines, and future integration of sustainable energy sources like batteries and fuel cells.
As regulatory and financial pressures to cut emissions grow, the partnership seeks to demonstrate the advantages of combining wind-assisted propulsion systems (WAPS) with DFE+. OceanWings’ wingsail technology, featuring Adaptive Trimming, continuously optimizes sail positioning based on the vessel’s aerodynamic profile. Romain Grandsart, COO of OceanWings, emphasized the potential for significant fuel savings and greenhouse gas emissions reductions, particularly for LNG carriers that spend considerable time at sea.
ABB’s Rune Lysebo highlighted the compatibility of their hybrid electrical propulsion system with the variable power from wind. This synergy aims to enhance operational efficiency. Dominik Thoma from Everllence noted that while WAPS creates variable propulsion demands, DFE+ provides precise load control, making it ideal for harnessing wind energy. The initial collaboration will focus on future LNG carrier concepts, with plans for broader applications in the cargo segment, aiming to reduce operational and capital expenditures for next-generation vessels.
