Global Transition with World-Leading Rolling Technology

Q: How does Davi technology address the extreme thickness and diameter requirements of next-generation wind foundations like monopiles?

As offshore wind turbines scale up, fabricating foundations requires rolling exceptionally thick steel plates. Davi meets this challenge with our heavy-duty MAV 3-roll variable-axis plate rolls, which are capable of rolling plates exceeding 150 mm (6 in) in thickness and diameters up to 15 m (50 ft). By adjusting the interaxis distance between the bottom rolls, the MAV system maximizes the leverage arm to provide superior pre-bending and re-rolling performance. This allows manufacturers to achieve the exact circularity required for seamless subsequent welding while maintaining high structural integrity and fatigue resistance in deep-water environments.

Q: How do Davi automated rolling lines improve productivity and repeatability in onshore and offshore wind tower manufacturing?

High-volume wind tower production demands speed, tight tolerances, and minimal reliance on manual trial-and-error. Davi offers dedicated, highly automated rolling lines integrated with our advanced iRoll eXtreme CNC control system and iCone software. This setup manages the position of pushers and hydro-guides in real time, allowing for continuous plate feeding to automate the rolling of complex conical tower sections with perfect repeatability. By coupling this automation with an integrated laser measuring system or AI-Vision, our lines eliminate test scrap and allow a single operator to safely manage the entire process, dramatically increasing manufacturing throughput and project ROI.

Q: What rolling solutions does Davi provide for the complex structural geometries of floating wind foundations?

Floating wind foundations, such as semi-submersibles, spar-buoys, and tension-leg platforms, require high-precision rolling for critical buoyancy tanks, structural columns, and bracing. Depending on the slenderness and design of the components, Davi provides both horizontal and vertical rolling systems using our advanced 3-roll MAV and 4-roll MCB geometries. These machines deliver the extreme precision needed to form complex, lightweight structural columns and high-fatigue-resistant jacket bracing, ensuring the structural stability of deep-water floating platforms while optimizing overall weight and fabrication times.

Q: How does Davi guarantee long-term operational continuity for high-output wind energy fabrication facilities?

Wind energy fabrication projects operate under strict deadlines where unscheduled downtime can heavily impact project ROI. Davi supports global manufacturers through a dedicated after-sales team and a comprehensive 24/5 telephone assistance program, coupled with secure remote support to diagnose and adjust PLC parameters in real-time. With over 300 dedicated wind lines installed worldwide and a stock of more than 11,000 spare parts, we ensure immediate availability of components and offer custom preventive maintenance packages that extend the useful life of your rolling lines, guaranteeing uninterrupted production and manufacturing continuity.

Davi is the undisputed global leader in rolling technology for the Wind Energy sector. With nearly two decades of experience and the recent record-breaking years, we provide the most advanced plate rolls to the industry's biggest players. From the monopiles of the North Sea to the next generation of floating foundations, Davi engineering is the backbone of renewable energy infrastructure.
