Monopile diameters are reaching 15 m with plate thickness exceeding 150–170 mm, and Davi’s MAV 3‑roll variable‑axis machines use individually tilting rolls, all‑rolls‑drive with flat gearboxes, and push‑push (below 3,000‑t capacity) or pull‑pull (above) symmetry to minimize flat ends and allow post‑weld circularity calibration. Turnkey systems integrate adaptive feeding, laser‑measured radii, and the iRoll eXtreme with iCone AI‑assisted controls for conical sections; the company states it has over 300 automated lines operating and a 70 % market share in wind‑sector rolling, with all machines built in Italy.
