Project Summary

There is a tendency to higher power offshore wind turbines, leading to larger turbine towers (5m diameter and greater) and a requirement for large diameter connection flanges between the tower sections and between the tower and foundation transition pieces. Currently, forged rings are specified, with inherently high cost and few suppliers worldwide. This leads to long lead times and higher costs for these strategic parts. RingMan will develop an alternative manufacturing route (using lower-cost cold rolled plate) which will enable the fabrication of large diameter wind tower flanges to be undertaken by our SME consortium members.

The project will enable the partners to commission:
