BAR Technologies has received Lloyd’s Register (LR) approval for its CFD-based P-Wind methodology. This system calculates the power generated by WindWings® installations. LR confirmed that the methodology aligns with IMO guidance (MEPC.1/Circ.896) and ITTC verification standards, giving shipowners confidence to quantify benefits under EEDI and EEXI regulations.
LR reviewed BAR’s CFD code, boundary conditions, grid independence, validation against experimental data, and force/wind matrix. Approval applies across all assessment categories. This provides a class-reviewed route to calculate WindWings® contributions without full-scale trials.
The approval sets a benchmark for wind-assisted shipping. Shipowners can now adopt wind propulsion with a verified methodology, reducing engineering costs and approval times.
John Cooper, CEO of BAR Technologies, said, “LR’s approval moves wind propulsion from promise to proof. Owners can now book verifiable P-Wind gains into EEDI and EEXI submissions with full transparency.”
Steve Windrim, LR Senior Client Relationship Manager, added, “This review confirms the robustness of BAR Technologies’ methodology. Independent verification reassures owners and yards that wind-assist solutions meet recognized technical standards.”
BAR Technologies’ studies show significant engine-power reductions on large product tankers. The methodology provides a repeatable template for future WindWings® installations.
The approval builds on BAR Technologies’ collaborations with global classification societies, strengthening its role in bringing wind propulsion from prototype to regulated reality.
