As Sif Group announces the successful ramp-up of its Maasvlakte II facility in Rotterdam, reaching a target output of four monopiles per week, the role of manufacturing equipment has taken center stage. Key to this production milestone is the integration of four Davi heavy-duty plate rolls, engineered to handle the massive dimensions of next-generation offshore wind foundations.
ROTTERDAM, Netherlands – Sif Group recently confirmed a significant leap in its manufacturing capabilities, affirming that its expanded facility at Maasvlakte II has reached a benchmark capacity of 4 monopiles per week. This achievement follows a period of intense equipment upgrades and process stabilization designed to meet the growing demand for 2,500-tonne monopiles.
At the heart of this production line is a fleet of four heavy-duty plate rolls supplied by Davi , the world’s leading manufacturer of heavy-duty rolling machines. The package provided to Sif includes two MCB (4-roll) and two MAV (3-roll variable axis) machines, each custom-equipped with specialized accessories essential for the demanding offshore wind environment.
Engineering for Mega-Monopiles
The transition to “mega-monopiles” requires equipment capable of handling extreme plate thicknesses and diameters while maintaining the rigorous tolerance required for offshore structural integrity.
Known for their high productivity and ease of automation, the MCB machines at Sif allow for a continuous, high-speed rolling process, reducing the time required to form the main sections of the monopiles.
MAV machines provide the versatility needed for the thickest plates. By adjusting the geometry of the rolls, the MAV maximizes the rolling force and minimizes the “flat end,” a critical factor when dealing with the heavy-gauge steel typical of Sif’s 2,500-tonne reference units.
