An important tool for reducing risks and costs in offshore wind is integrated, intelligent monitoring of the foundation structures. If well implemented an integrated monitoring approach will continuously track the 'state of health' of a foundation and identify in a very early stage the onset of structural problems. This allows early, low cost repairs, optimal […]
