LR Review Confirms Robustness of GT Wings’ Wind Propulsion Methodology

Lloyd’s Register has verified the performance methodology for GT Wings’ wind propulsion technology following ten months of North Atlantic sea trials. This milestone establishes a transparent, data-driven framework for shipowners to quantify fuel savings and carbon reductions.

London | February 19, 2026 – In a move set to bolster investor and shipowner confidence in wind-assisted propulsion, Lloyd’s Register (LR) has formally verified the performance assessment methodology for GT Wings’ AirWing™ Jet Sail technology.

The announcement was made during the RINA Wind Propulsion 2026 Conference in London, marking a significant step toward the “bankability” of wind-assist systems. The verification follows ten months of grueling real-world testing aboard the MV Vectis Progress, a general cargo vessel operated by Carisbrooke Shipping.

Proving the “Wind Reward” in Real-World Conditions

While wind propulsion has seen a surge in pilot projects, the industry has struggled with “performance transparency”, the ability to prove exactly how much fuel is being saved versus environmental variables like currents and sea states.

LR’s verification confirms that GT Wings’ methodology aligns with international standards ISO 19030 and ITTC practices. This allows the company to isolate the specific propulsive benefits of the AirWing™ from other operational factors, providing a “defensible” data set for charterers and financiers.

Ten Months in the “Great Lakes and North Atlantic”

The 20-meter AirWing™ demonstrator hasn’t had an easy trial. Since its installation in March 2025, the system has navigated:

• North Atlantic Winter: Testing structural integrity in extreme weather.
• The Great Lakes: Operating in confined, high-traffic freshwater routes.
• The Caribbean: Evaluating performance in variable tropical wind patterns.

“Independent verification of performance assessment methodologies is essential to building confidence in emerging maritime technologies,” said Andrew Hurford, Senior Specialist Marine at Lloyd’s Register.

High Power, Low Footprint: The Jet Sail Advantage

The AirWing™ is distinct from traditional sails or rotors. Using proprietary Jet Sail technology, it is designed to generate high propulsive power with a minimal deck footprint and air draft. This “high-lift” profile makes it a prime candidate for vessels where deck space is at a premium or where cargo handling equipment restricts larger installations.

Liam Campbell, Chief Commercial Officer at GT Wings, noted: “Our vision has been to drive the transition through measurable, data-driven performance. This is an important step toward scaling wind-assisted propulsion across global shipping.”

Analysis: Bridging the Confidence Gap

For the bunkering and marine fuel sector, the rise of verified wind-assist technology represents a shift in the “fuel mix.” As FuelEU Maritime and the EU ETS increase the cost of carbon, wind is no longer just a “green experiment”, it is a financial hedge.

GT Wings – Inside the Tech

GT Wings is a London-based maritime technology disruptor on a mission to bring wind-assisted propulsion to one-third of the global fleet. Unlike traditional sail concepts, the company specializes in high-lift, compact engineering designed to bridge the gap between ambitious decarbonization targets and the practical realities of commercial shipping.

The Flagship: AirWing™ Technology

The core of their portfolio is the AirWing™, a patented “Jet Sail” system. Key differentiators include:

• High Power Density: Delivers significant thrust from a remarkably small deck footprint.
• Retrofit Ready: Engineered for easy integration on existing vessels without extensive structural overhauls.
• AI-Driven Controls: Utilizes automated sensors to optimize wing positioning in real-time, ensuring maximum fuel savings across variable sea states.

A Track Record of Innovation

GT Wings’ rapid ascent in the “Green Tech” space is backed by significant industry accolades, signaling strong confidence from maritime stakeholders:

• Startup of the Year (2023): Maritime UK Awards.
• Sustainability Leadership: Winners of the PIER71™ Maritime Sustainability Award.
• Smart Port Innovator: 3rd Place in the PIER71™ Smart Port Challenge 2024.

The Strategic Outlook

As the maritime industry faces the double pressure of the EU ETS and FuelEU Maritime, GT Wings offers a “turn-key” solution. By partnering with a global network of class-approval and installation experts, they provide shipowners a seamless pathway from initial concept to a commissioned, wind-assisted fleet.

“We are redefining the future of shipping by harnessing the only free, unlimited, and zero-emission fuel source available: the wind.” — GT Wings Vision Statement
