Windship Technology

What Windship Technology does

Windship Technology Ltd is a privately-held UK engineering company developing wind-assisted propulsion and True Zero Emission solutions for the commercial shipping industry. Its core product is the Windship Auxiliary Sail Propulsion System (WASPS), a patented triple-wing foil rig standing 35-48 metres tall, installed on bulk carriers and tankers over 30,000 DWT to deliver verified fuel savings of at least 30% annually (and 49% on Aframax tankers per DNV's independent assessment). The rig is integrated into a broader whole-ship solution that pairs the wind propulsion system with Calix's RECAST onboard carbon capture technology (under an exclusive joint development agreement), diesel-electric drive optimization, solar arrays, optimized hull forms, and proprietary weather routing software, enabling claimed 100% CO2 capture alongside material fuel and emissions reductions.

The company monetizes through hardware sales and installation of rigs on new-build or retrofit vessels, technology licensing (with patents granted or pending in 30+ jurisdictions), and integrated whole-ship design packages for shipyards. Commercial activity is enterprise field sales targeted at ship owners, operators, and charterers in the bulk carrier and tanker segments, supported by DNV class validation and UK government demonstration funding (notably £4m from the Clean Maritime Demonstration Competition Round 3 in February 2023). Headcount is 1-10 and the company is pre-revenue, with its first commercial-scale demonstration (a 36m tri-foiled rig on a 15,000 DWT bulker combined with carbon capture) currently underway. The technology has received the DNV Approval in Principle, Motorship Award (2021), and features in TradeWinds and Sunday Times/Raconteur coverage, positioning the company within the IMO 2050 net-zero regulatory backdrop.

Core offering

Windship Technology develops and sells the Windship Auxiliary Sail Propulsion System (WASPS), a patented triple-wing foil rig system (36-48 metres) for auxiliary wind propulsion on commercial vessels over 30,000 DWT. The company also offers a whole-ship True Zero Emission Solution that combines the wind propulsion rigs with Calix's RECAST carbon capture technology, solar arrays, diesel electric drive, optimised hull shapes, and weather routing software. Revenue is generated through rig hardware sales, retrofit installation, technology licensing, and whole-ship design packages.

Product overview

Windship Technology offers a holistic True Zero Emission solution for commercial shipping comprising the Windship Auxiliary Sail Propulsion System (WASPS) as the core product—a patented triple-wing rig technology (35-48m height) that harnesses wind power. This is combined with RECAST carbon capture technology from Calix Limited partnership, weather routing software, and diesel electric drive optimization. The system is designed for bulk carriers and tankers over 30,000 DWT, achieving verified fuel savings of 30% annually from rigs alone, and up to 80% combined with slow steaming and other optimizations.
