In a recent report by LR, the BRANDS HATCH has made waves as the first Aframax tanker built with wind-assisted propulsion, delivered by Shanghai Waigaoqiao Shipbuilding Co., Ltd. (SWS) to Union Maritime Limited (UML). This impressive vessel boasts a deadweight tonnage of 114,000 and is now recognized as the most powerful cargo ship of its type utilizing wind energy.

The official naming ceremony took place on June 11, 2025, at SWS’s shipyard in Shanghai. What sets this tanker apart are its three WindWings®—rigid structures resembling sails that tower at 37.5 meters each—crafted by BAR Technologies based in the UK.

These innovative WindWings® are designed to adapt their angle and camber based on prevailing wind conditions, enhancing aerodynamic efficiency and providing additional thrust for navigation. Independent evaluations suggest that under optimal conditions while cruising at 20 knots,these wings could reduce daily fuel consumption by approximately 14.5 tonnes and cut carbon dioxide emissions by up to 45 tonnes. Over an entire year of operation, it’s anticipated that BRANDS HATCH will achieve a fuel savings of around 12%, translating to nearly 5,000 tonnes less CO₂ released into the atmosphere.

Lloyd’s Register (LR) played an instrumental role in this project as the classification society overseeing BRANDS HATCH’s development from concept thru delivery—the first instance where a Chinese classification society has endorsed wind-assisted technology for crude oil tankers.

LR provided comprehensive technical support throughout various phases including design approval processes like Approval in Principle (aip), hazard assessments such as HAZID and HAZOP studies, design evaluations, and collaboration with flag authorities to ensure compliance with safety standards. they also oversaw installation procedures and monitored sea trials which validated both safety measures and operational effectiveness of the new propulsion system.

A senior surveyor from LR’s Marine & Offshore team noted that this initiative marks significant progress toward integrating wind propulsion into larger maritime vessels. Another specialist from LR highlighted that BRANDS HATCH is pioneering this technology within China; they emphasized their commitment to assisting clients through all stages—from engineering reviews to testing phases—and expressed enthusiasm about future collaborations with shipowners interested in similar advancements.

The CEO of BAR Technologies revealed plans for another vessel currently being constructed at Yangzijiang Shipyard for UML which will also feature WindWings®, produced by China Merchants Energy Tech in Shanghai.

During the naming event in Shanghai, LR’s President for Greater China hailed BRANDS HATCH as a landmark achievement in commercial shipbuilding. He remarked on how collaborative efforts between LR and Chinese shipyards are paving the way for environmentally sustainable innovations within global shipping practices.
