Wind propulsion company GT Wings has secured approval from classification society RINA for a performance assessment tool designed to evaluate the potential savings offered by its AirWing wind propulsion system, according to Ship & Bunker.
The tool was developed in collaboration with maritime performance modelling firm Blue Wasp Marine and is intended to estimate potential reductions in bunker fuel consumption, emissions, and regulatory costs across different vessel types and routes.
What the Approval Covers
RINA reviewed and verified both the modelling methodology and the assessment framework underpinning the tool. According to Ship & Bunker, the classification society confirmed that both elements align with recognised industry standards and guidelines.
GT Wings stated that the tool is designed to support shipowners in evaluating the potential benefits of AirWing technology at an early stage, assisting with both technical and commercial decision-making. The company also noted that it provides a more consistent and transparent basis for assessing wind-assisted propulsion projects.
Real-World Deployment and Demand
The AirWing system is not purely at the concept stage. Ship & Bunker reports that the technology is already installed on Carisbrooke Shipping’s MV Vectis Progress, and that GT Wings has completed more than 80 early-stage performance assessments to date.
Additional orders have been secured from Grieg Maritime Group, indicating growing commercial interest in the technology.
GT Wings has previously claimed its wind propulsion systems can reduce bunker consumption by up to 30%, though results will naturally vary depending on vessel type, route, and operating conditions.
Does This Matter to You?
For those tracking alternative propulsion technologies and their potential impact on fuel consumption and regulatory compliance, this development carries practical relevance. The RINA approval lends credibility to the assessment methodology, which could make it easier for owners and operators to justify wind-assisted propulsion investments during early project evaluation phases.
With shipping facing increasing pressure from emissions regulations, independently verified performance tools may play a growing role in how owners compare and select fuel-saving technologies. The approval also signals that wind propulsion is maturing beyond demonstration projects, with standardised evaluation frameworks beginning to emerge.
As more vessels adopt wind-assisted systems, the industry may see broader adoption of such approved modelling tools to support procurement, chartering, and voyage planning decisions.
