F.lli Righini Srl, a leading engineering and manufacturing company in offshore energy solutions, has successfully delivered numerous Jacket Pile Grippers (JPGs) for multiple offshore wind projects across the North Sea and Baltic Sea. These tailor-made systems play a critical role in the precise installation of jacket foundations for Wind Turbine Generators and Offshore Substations, contributing to the reliable and sustainable expansion of renewable energy infrastructure worldwide.
A Vital Tool for Jacket Installation Jacket Pile Grippers are essential for the temporary positioning and leveling of jacket structures during offshore installation and the early phase of grouting. By securing the jacket in place on the seabed, JPGs ensure the structural integrity and alignment necessary for long-term performance in harsh marine environments.
F.lli Righini has developed a solid track record in this field, delivering:
This extensive project portfolio has allowed the company to refine both the mechanical / hydraulic design and the full production cycle, resulting in optimized and high-quality solutions.
Advanced Engineering and Tailored Solutions Each JPG is engineered using comprehensive Finite Element Analysis (FEA) based on full 3D models, incorporating the jacket leg, pile, and JPG itself to validate on-bottom stability. In some configurations, F.lli Righini has successfully integrated a Tailing Jack system to meet stringent DNV Early Age Cycling requirements, demonstrating adaptability and technical rigor in the face of demanding specifications.
A key technical feature is the hydraulic system integrated within the JPG, which allows the jacket to be held firmly in position for the entire duration of the grout curing phase without requiring external power supply. The hydraulic system has been extensively tested and validated by F.lli Righini in previous wind farm projects.
