What BAR Technologies does

BAR Technologies is a Portsmouth, UK-based private company founded in 2017 that designs and commercializes WindWings, a rigid wind-assisted propulsion system for large commercial vessels. The technology consists of 123-foot (~37.5 metre) fixed rigid sails mounted on a vessel's deck to capture wind energy, providing auxiliary propulsion thrust that reduces main engine fuel consumption by 1.5 to 11 tonnes per day per vessel depending on conditions, and avoids over 2,300 tonnes of CO2 emissions annually per LR2 tanker. The system is fuel-agnostic and integrates with newbuild and retrofit programs across tanker segments (MR2, LR2), gas carriers, and dry bulk vessels, with naval architecture handled by SDARI and manufacturing by Xiamen Shipbuilding Industry.

BAR Technologies generates revenue through per-vessel hardware sales and installation contracts, supplemented by a technology licensing and co-development model signaled by its MOU with HD Hyundai Heavy Industries. The company's go-to-market combines direct sales to shipowners (e.g., Union Maritime, the unnamed owner of the Suzuka and Long Beach LR2 tankers) with channel partnerships: Panmarine & Industrial Services covers Greek and Cypriot markets, Wuhu Shipyard and Xiamen Shipbuilding Industry serve as OEM manufacturing and assembly partners, and HHI represents a pathway to mass-market deployment through Korean shipbuilding. Distribution is heavily dependent on regulatory approvals, including SOLAS equivalency from the Marshall Islands Flag State Administration and classification by Bureau Veritas, which the company treats as a core moat.

The company has achieved commercial validation through deployments on the Pyxis Ocean (Cargill, 11 tonnes/day fuel savings), 13 WindWings fitted across 5 vessels with 4 more launching before end-2026, and active participation in IMO's regulatory development for wind propulsion safety guidelines (targeted for 2029). Customer concentration is high given the small number of vessel programs, and revenue recognition is lumpy and tied to shipyard delivery schedules, making forward revenue visibility dependent on the conversion of partnerships (HHI, Panmarine) into binding orders.

Revenue model

1. WindWings Hardware Sales and Installation: BAR Technologies generates revenue through the sale and installation of WindWings wind propulsion systems onto vessels. This includes newbuild integrations (e.g., LR2 dual-fuel tankers Suzuka and Long Beach) and retrofits (e.g., existing tankers). Revenue is earned per vessel with per-unit pricing tied to wing count and vessel specifications.
2. Technology Licensing and Co-Development: Through partnerships with shipbuilders such as HD Hyundai Heavy Industries, BAR Technologies licenses WindWings technology for integration into vessel designs. The MOU with HHI aims to develop scalable, practical wind-assisted propulsion systems across vessel segments, suggesting licensing revenue streams for design integration and technology deployment.

Core offering

BAR Technologies designs, develops, and commercializes WindWings, a rigid wind-assisted propulsion system consisting of large 123-foot (37.5 metre) wing sails installed on commercial vessels to harness wind energy for auxiliary propulsion. The company supports both newbuild integrations and retrofits of the system, working with shipyards, naval architects, flag state administrations, and classification societies to deliver SOLAS-equivalent compliant deployments on tankers, gas carriers, and bulk carriers.

Product overview

BAR Technologies offers WindWings, a single wind propulsion technology product. WindWings are large rigid sails (up to 123 feet tall) designed for installation on commercial vessels including tankers, gas carriers, and MR2 vessels. The technology harnesses wind energy to provide auxiliary propulsion, reducing fuel consumption by 1.5-11 tonnes per day depending on vessel size and conditions, while avoiding CO2 emissions of 2,300+ tonnes annually per vessel. The company also provides regulatory navigation support to help shipowners integrate wind propulsion technology within existing safety frameworks.

Partnerships

Nine partnerships are on record, tiered core.

• HD Hyundai Heavy Industries (HHI)coreStrategic or Co-development Partner · 3 June 2026HD Hyundai Heavy Industries (HHI) and BAR Technologies signed an MOU to collaborate on integrating WindWings technology into vessels to improve fuel efficiency and reduce emissions. The partnership aims to develop scalable, practical wind-assisted propulsion systems across various vessel segments, including gas carriers. This is a flagship strategic partnership with one of the world's largest shipbuilders, providing a pathway to mass-market deployment.
• Panmarine & Industrial ServicescoreChannel Partner/ Reseller/ Distributor · 30 May 2026BAR Technologies appointed Panmarine & Industrial Services as a commercial consultant to capture the Greek and Cypriot maritime markets. The partnership precedes the company's appearance at Posidonia 2026 and positions it to leverage Greece's status as a major maritime hub, with 13 WindWings already fitted across five vessels and four more launching before end of 2026. Panmarine acts as a regional channel partner driving sales in a key shipping market.
