HD Hyundai Heavy Industries and BAR Technologies Sign MOU for WindWings® (Wind-Assisted Propulsion Systems) Collaboration in International Shipping News 02/06/2026 HD Hyundai Heavy Industries (HHI) and BAR Technologies have signed a Memorandum of Understanding (MOU) to establish a strategic partnership focused on technical collaboration and commercial opportunities for the integration of WindWings®. As one of the world’s leading shipbuilders, with its Ulsan yard recognised as the largest shipbuilding facility globally, HHI brings significant scale to the deployment of the technology. This agreement establishes a joint engineering approach at the vessel design stage, enabling a more integrated and consistent application of WindWings® in newbuild vessels. The two companies will collaborate on the technical development of interfacing the WindWings® control system with HHI’s integrated vessel control system and developing performance verification methodologies to support scalable commercial deployment. HHI’s collaboration with BAR Technologies reflects shared confidence in the performance and reliability of the three-element rigid wing sail design, and its potential to contribute to fuel efficiency and emissions reduction in commercial shipping. The collaboration is expected to support the expansion of wind-assisted propulsion across a broader range of vessel segments, including gas carriers, as shipowners seek viable solutions to improve efficiency and reduce emissions. Having delivered more than 5,000 vessels to shipowners across over 60 countries since its founding, HHI brings the scale and industry reach to support this expansion effectively across a wide range of vessel types. The MOU has an initial term of three years and reflects a shared focus on deploying practical, lower-emission technologies at scale within the maritime sector. As regulatory and commercial pressures intensify, wind-assisted propulsion is becoming an increasingly important lever for shipowners
