Dillinger, a leading steel producer, has unveiled new steel grades specifically designed for monopiles used in offshore wind turbines. These innovative materials, developed in collaboration with Saarland University, RWTH Aachen University, and other partners, are engineered to withstand harsh conditions such as storms, waves, and saltwater exposure while maintaining economic production efficiency.
The new steel grades are compatible with high-energy welding techniques like submerged arc welding and electron beam welding, significantly reducing production times. This advancement addresses the challenges posed by the large-scale industrial production of monopiles, which require extensive welding due to their massive size and thickness.
The project, funded by the German Federal Ministry for Economic Affairs and Climate Protection, recently concluded after nearly four years of research and development. Dillinger's efforts mark a significant step forward in supporting renewable energy infrastructure with durable and efficient materials.
