An introduction to shared anchor in weak rock for floating systems
An introduction to shared anchor in weak rock for floating systems
Floating offshore wind is currently going through a significant expansion. However, there are existing gaps between naval architects and geotechnical experts that need to be bridged to achieve cost effective solutions. In this paper, Cathie presents a holistic methodology to cover some of these gaps. This paper investigates the opportunity of novel shared anchor concepts with specific reference to anchoring in rock. This solution not only offers a potential significant reduction on overall number of anchor points but also could allow a substantial reduction of the CAPEX/OPEX and the associated risk mitigation strategies. The study focuses on multiple lines anchor system simulations of anchor forces generated with example semisubmersible structure and a 15 MW wind turbine. The anchors in rock are assessed via state-of-the-art design methods for drilling and grout foundation and driven pile solutions with particular attention to the global capacity based on multi load cases.
