In a significant step toward sustainable maritime innovation, Lloyd’s Register (LR) has independently reviewed and approved BAR Technologies’ P-Wind calculation method. This methodology determines the amount of power generated by WindWings® installations, a wind-assisted propulsion system designed to improve vessel efficiency and reduce carbon emissions.
The approval confirms that BAR Technologies’ computational fluid dynamics (CFD) model aligns with International Maritime Organization (IMO) and ITTC verification standards, providing shipowners with a reliable way to quantify regulatory benefits under EEDI and EEXI.
Ensuring Accuracy and Transparency in Wind Propulsion Assessment
Lloyd’s Register conducted a detailed technical review of BAR Technologies’ methodology, covering every key parameter from CFD code specifications and boundary conditions to validation against experimental data. The outcome confirmed that the model is robust, transparent, and compliant with industry standards. This allows shipowners to confidently calculate the propulsive contribution of WindWings® without conducting expensive and time-consuming full-scale trials.
The approval removes one of the biggest challenges in adopting wind propulsion systems: the lack of standardised, verifiable data to prove performance benefits. Now, shipowners can rely on a class-reviewed pathway to evaluate wind-assist efficiency, helping them meet IMO’s carbon reduction requirements efficiently.
Advancing Wind Propulsion Toward Mainstream Adoption
This approval marks a turning point for the shipping industry. By providing a repeatable, class-approved model, BAR Technologies has simplified the approval process for future projects, reducing lead times and engineering costs. As John Cooper, CEO of BAR Technologies, stated, this milestone transforms wind propulsion from “promise to proof,” demonstrating that WindWings® deliver measurable and verifiable efficiency gains.
The collaboration between BAR Technologies and Lloyd’s Register represents a broader industry move toward clean energy integration. With proven results on large product tankers and ongoing partnerships with global classification societies, BAR Technologies continues to lead the way in making wind propulsion a trusted and essential tool for maritime decarbonisation.
Lloyd’s Register’s approval of BAR Technologies’ P-Wind methodology is more than just a technical validation it is a major step in the industry’s journey toward zero-emission shipping. By providing a scientifically validated and class-approved framework, this achievement empowers shipowners to adopt wind-assisted technologies with confidence. As the maritime sector pushes forward with decarbonisation goals, innovations like WindWings® are proving that sustainable propulsion is not only possible but practical and profitable.
