BAR Technologies Signs New Collaboration Agreement with CMET to Boost Availability of 20-24m WindWings®

[ 21 February 2025] – Following the successful launch of the new 20m and 24m WindWings® in September 2024, BAR Technologies and CM Energy Tech Co., Ltd (CMET) have entered into a collaboration agreement to begin production of these models, responding to the surge in market demand from shipowners and operators of Handymax bulkers, chemical tankers, and general cargo vessels. Building on the strong demand BAR Technologies are seeing for their existing 37.5m WindWings®, the introduction of these new models ensures that wind-assisted propulsion is accessible to a broader range of vessel types. This development marks a significant step in making wind-assisted propulsion systems a reality for even more shipowners and supporting the industry’s drive towards greater fuel efficiency and reduced emissions. The new models are projected to deliver up to 0.7 tonnes of fuel savings per WindWing® per day on average on worldwide routes, representing a substantial contribution to global decarbonisation efforts.

The agreement between BAR Technologies and CMET reinforces the rapid acceleration of wind propulsion adoption. With tightening regulations under FuelEU Maritime and the IMO’s 2030 emissions targets, shipowners are actively seeking solutions that can be retrofitted to deliver significant efficiency gains without requiring a shift to costly alternative fuels or major fleet overhauls. The new WindWings® models are specifically designed for mid-sized vessels and provide a practical and commercially viable path to emissions reductions.

John Cooper, CEO of BAR Technologies, said the industry’s response to WindWings® has exceeded expectations, particularly for the smaller models suited to Handymax and mid-sized fleets.

“One of the biggest shifts we’ve seen is that stakeholders now trust the physics behind our three-element wing design, which DNV Maritime has rigorously validated. By formalising our partnership with CMET, we are ensuring that shipowners have access to scalable wind propulsion technology that is both commercially and operationally viable. The interest we have seen from the market reflects a clear demand for proven solutions that reduce fuel consumption and emissions in a cost-effective manner.”

Huafeng Zhan, Executive President of CMET, echoed this sentiment, emphasising the growing momentum behind wind propulsion in the maritime sector.

“The demand for WindWings® highlights the urgent need for sustainable, efficient solutions in shipping. CMET is proud to partner with BAR Technologies in expanding marketing and production, bringing this innovative technology to a broader segment of the market. This collaboration strengthens our shared commitment to maritime decarbonisation and delivering practical solutions for shipowners navigating new regulatory pressures.”

The expansion of marketing and production with CMET also strengthens BAR Technologies’ ability to meet increasing demand. The WindWings® portfolio now covers a broader range of vessel sizes, ensuring that more shipowners can integrate wind propulsion technology without compromising operational flexibility. Designed with durability in mind, WindWings® incorporate a fail-safe self-feathering system capable of handling extreme conditions, including winds of up to 100 knots. “BAR Technologies’ innovative technology, combined with CMET’s advanced manufacturing expertise, allows us to efficiently scale production and deliver this pioneering solution to a wider market,” added Cooper. “This partnership is built on a shared vision: accelerating maritime decarbonisation and providing shipowners with practical, future-ready solutions as they navigate evolving regulatory landscapes.”

BAR Technologies WindWings® offers a groundbreaking approach to maritime propulsion, significantly enhancing efficiency and sustainability. Their patented three-element wing design generates 2.5 times the lift of traditional single-element wings, ensuring superior thrust and performance. Unlike conventional wind-assisted systems, WindWings® operate without continuous spinning or suction fans, resulting in minimal power consumption. Their fully adjustable camber and angle of attack enable automatic optimisation for maximum efficiency across varying wind speeds and directions. By harnessing the vast, untapped power of wind, WindWings® significantly improve fuel efficiency, reduces emissions and provides a self-sufficient, zero-emission solution that enhances both profitability and sustainability. All WindWings® models are designed for both newbuilds and retrofits, requiring minimal external power and eliminating the need for constant energy consumption.

With the IMO’s 2030 decarbonisation targets fast approaching, shipowners are under growing pressure to make strategic fleet decisions that will keep them compliant in the years ahead. The partnership between BAR Technologies and CMET ensures that WindWings® remain a readily available, field-tested and scalable solution for the industry. By focusing on precision-engineered technology that aligns with real-world operational needs, BAR Technologies is driving the UK’s commitment to delivering the transition to a more sustainable and fuel-efficient shipping sector.

Key Features of the 20m-24m WindWings®

• Optimised thrust and fuel savings: The patented three-element rigid wingsail with passive boundary layer control eliminates the need for suction fans or spinning mechanisms, reducing energy consumption.
• Lightweight and easy integration: Weighing under 30 tonnes, these units require minimal deck reinforcement, making them ideal for forecastle or side deck installation.
• Foldable and non-foldable variants: Designed for maximum operational flexibility, the wings can be compacted for ease of navigation during pilotage and port operations.
• Fully electric operation: The wings operate entirely on electric power, ensuring simplified installation and maintenance while maintaining high performance.
• Fail-safe extreme weather resilience: A self-feathering mechanism allows the wings to withstand true wind speeds of up to 100 knots.
• Turnkey solution: Comprehensive support from initial feasibility assessments to performance monitoring ensures seamless integration and operational efficiency.
• WindWings®

BAR Technologies patented three-element wing design is unique in the marketplace, delivering 2.5 times the lift of a single-element wing. Unlike conventional wind-assisted propulsion systems, WindWings® require no continuous power for suction fans or mechanical spinning. They automatically adjust camber and angle of attack for optimised efficiency, offering a proven, scalable solution for emissions reduction.
