The global transition toward offshore wind energy is pushing engineering boundaries. As wind turbines soar to unprecedented heights, foundation structures like monopiles, transition pieces, and jacket foundations are demanding exceptionally thick steel plates and complex geometries. For heavy-fabrication leaders, manufacturing these massive cylindrical and tapered conical structures requires absolute precision. Scaling up production to meet aggressive project deadlines must never come at the expense of safety, strict dimensional tolerances, or local compliance. This was the context faced by GS Entec, a prominent South Korean manufacturer navigating highly demanding technical environments and strict local certifications.
The Solution: A Synergy of Heavy-Duty Bending Power
To address these complex manufacturing challenges, GS Entec partnered with Davi to implement two heavy-duty plate rolling machines custom-engineered for wind energy structures. The complete scope of supply includes:
The MCB (Four-Roll Plate Roll): Built for high-volume repeatability and automated ease of use, making it the ideal system for heavy cylindrical cans.
The MAV (Three-Roll Variable Axis Plate Roll): Engineered with three fully tilting rolls to handle the thickest plate structures and complex conical geometries.
Both heavy-duty systems are equipped with specialized accessories and advanced control software—including automated feeding and precision control units—enabling GS Entec to manage complex heavy-rolling projects with extreme accuracy.
By introducing Davi's state-of-the-art rolling technology, GS Entec gains concrete advantages across their production floor:
Minimized Material Waste: Thanks to the MAV’s variable-axis design, operators can position the plate exactly at the tangent point. This achieves the shortest possible flat end, eliminating costly manual correction and pre-bending material waste.
Exceptional Conical Bending: The MAV allows for stress-free tilting of up to 100 mm (4 inches) for every 3 meters (10 feet) of roll length, streamlining demanding tapered section rolling.
Process Stability: Powered by our patented Servo-Tronic system, the rolls maintain perfect hydraulic and mechanical parallelism even in the event of an electronic malfunction, keeping downtime to an absolute minimum.
Regulatory Compliance: Davi custom-supplied all components—specifically motors and electric systems—in full compliance with rigorous local Korean certification standards, guaranteeing absolute operational safety and structural performance.
