LR delivers classification for world-first WindWings® Aframax tanker BRANDS HATCH
The LR-classed vessel is fitted with three 37.5-metre-tall WindWings® developed by UK-based BAR Technologies.
Built by Shanghai Waigaoqiao Shipbuilding Co., Ltd. (SWS) for Union Maritime Limited (UML), the 114,000 DWT vessel is now the most powerful wind-assisted cargo ship in operation.
The LR-classed vessel is fitted with three 37.5-metre-tall WindWings® developed by UK-based BAR Technologies. These rigid sails are capable of intelligent aerodynamic adjustment in angle and camber to optimise aerodynamic efficiency, providing additional thrust that reduces fuel consumption and lowers carbon emissions.
The system has achieved independently verified performance results, reducing daily fuel consumption by up to 14.5 tonnes and CO₂ emissions by up to 45 tonnes under ideal wind conditions at 20 knots. Under typical operating conditions, the vessel is projected to achieve an annual fuel saving of 12%, equating to a reduction of nearly 5,000 tonnes of CO₂ per year.
As the first classification society in China to support a wind-assisted propulsion system on a crude oil tanker, LR provided full technical services from design to delivery. This included Approval in Principle (AiP), HAZID/HAZOP processes, design appraisal, and coordination with flag authorities to ensure the WindWings® installation met rigorous safety and compliance standards. LR’s involvement extended to installation supervision and sea trials, which confirmed the system’s performance and seaworthiness.
Laurent Cadji, Managing Director at Union Maritime, said: “The delivery of Brands Hatch is a powerful example of how Union Maritime is responding to the evolving regulatory landscape by deploying smart and environmentally responsible technologies. As our first vessel with WindWings®, and with more to follow, it signals the beginning of a new era for Union Maritime, and the wider industry, as we combine our deep sector expertise with cutting-edge innovation to drive greater efficiency and lower our carbon footprint.”
John Cooper, CEO BAR Technologies, said: “The success of this project paves the way for additional vessels of similar size and configuration under LR Class. This includes another with the same owner, ship type and technology that is already underway at Yangzijiang Shipyard, with WindWings® again manufactured by China Merchants Energy Tech in Shanghai.”
At the naming ceremony, Sau Weng Tang, LR President of Greater China said: “The ‘BRANDS HATCH’ project marks a significant milestone in bringing innovative technology into commercial shipbuilding. It reflects the strong collaboration between LR and Chinese shipyards in driving the transition to greener shipping. Our full technical involvement throughout the project has ensured the vessel meets the highest international standards for safety, performance, and compliance.”
