Bar Technologies’ wind power verification approved by LR

Lloyd’s Register (LR) has approved technology developed by UK-based Bar Technologies, a marine engineering and wind power specialist, for its wind power calculation methodology. Using computational fluid dynamics (CFD), Bar Technologies’ P-Wind system measures the power generated by its WindWings® technology.

The new measurement system confirms the company’s approach and its alignment with IMO and International Towing Tank Conference methodologies. LR has approved BAR Technologies’ technology as acceptable over all assessment categories including CFD code specification, boundary conditions to grid independence, validation against experimental data, and the generation of the installation-specific force/wind matrix.

The verification is important because a class-approved measure model removes uncertainty and doubts about power saving benefits. Future projects are now likely to proceed more quickly.

Bar Technologies’ CEO, John Cooper, said: “This approval from Lloyd's Register moves the conversation from promise to proof. It shows that our modelling delivers decision-grade numbers trusted by class and that owners can book real, verifiable P-Wind gains into their EEDI and EEXI submissions today. It's another milestone in taking wind propulsion from experimental to essential.”

LR’s Steve Windrim, Senior Client Relationship manager for BAR Technologies, added: “Our review of Bar Technologies' methodology confirms its robustness against current international references for innovative energy-efficiency technologies. Independent reviews such as this give owners and yards the confidence that wind-assist solutions are being quantified to recognised technical standards, supporting safe and effective integration as the sector accelerates towards decarbonisation.”
