• GT Wings has secured Lloyd’s Register verification of sea trials performance
assessment methodology for its AirWingTM Jet Sail.
• The verification follows 10 months’ ongoing deployment of GT Wings’ AirWingTM
technology onboard Carisbrooke Shipping’s MV Vectis Progress.
• The news marks a key step in building industry confidence around the performance
transparency and scalability of high-lift wind propulsion systems.
London, UK, 19 February 2026: GT Wings, provider of unique wind propulsion systems to
the commercial shipping industry, has secured Lloyd’s Register verification of sea trials
performance assessment methodology for its AirWingTM Jet Sail technology.
The announcement, made as industry stakeholders convened in London this week for
RINA’s Wind Propulsion Conference, follows some ten months of commercial operation of a
20-metre AirWingTM onboard MV Vectis Progress, a general cargo vessel operated by
Carisbrooke Shipping.
Installed in March 2025, the AirWingTM has been operating on live commercial routes across
the Atlantic, navigating North Atlantic winter conditions, as well as on voyages through the
Great Lakes and additional Caribbean sailings. The Jet Sail technology has demonstrated
performance and reliability in a diverse range of sea and weather conditions, enabling GT
Wings to seek to collect operational and environmental data to assess real-world fuel and
emissions savings.
Independent verification for transparent decarbonisation
Lloyd’s Register has verified that GT Wings’ performance assessment methodology aligns
with recognised industry standards, including ISO 19030 and ITTC performance analysis
practices. The review confirms that the approach used to isolate and quantify wind-assisted
propulsion benefits is technically robust and suitable for in-service performance evaluation.
Andrew Hurford, Senior Specialist Marine – Maritime Asset and Operational Performance,
Lloyd’s Register commented:
“Independent verification of performance assessment methodologies is essential to building
confidence in emerging maritime technologies. We are pleased to have reviewed GT Wings’
approach and confirm its alignment with recognised in-service performance standards.”
As wind-assisted propulsion moves from pilot projects to commercial deployment,
transparent and defensible performance measurement is critical. Independent verification of
methodology provides shipowners, charterers and financiers with confidence that projected
fuel and emissions savings are assessed using recognised standards and reflect real
operational conditions.
Delivering high power from limited deck space
AirWingTM is a rigid wind propulsion system based on proprietary Jet Sail technology,
designed to generate high propulsive power from limited available deck space and air draft.
This makes it particularly well suited to vessels where conventional wind-assist solutions
may be constrained.
Liam Campbell, Chief Commercial Officer, GT Wings, said:
“We are proud to mark this milestone at RINA Wind Propulsion 2026 alongside the
innovators shaping the future of maritime propulsion. From the start, our vision has been to
drive the transition through measurable, data‐driven performance. Lloyd’s Register’s
verification confirms our alignment with international standards and validates that our
performance predictions are grounded in real‐world evidence. It is an important step toward
scaling wind‐assisted propulsion across global shipping and strengthening confidence in this
technology as a viable pathway to reducing carbon emissions.”
GT Wings will continue to monitor and analyse operational data from Vectis Progress as part
of its ongoing validation programme. This performance analysis is based on a methodology
aligned with that accepted by Lloyd’s Register, which indicates that the resulting conclusions
should be considered valid. Independent verification of the implementation is ongoing.
Robert Wester, Director, Carisbrooke Shipping commented:
“Reducing emissions remains a key priority for Carisbrooke and wind propulsion is a
practical and effective solution for lowering carbon emissions across our fleet.”
