Research project: Floating wind and wave energy systems are central to Ireland’s renewable
energy ambitions, particularly along the Atlantic west coast, where resources are abundant but
marine conditions are among the harshest in Europe. Reliable anchoring systems must
withstand decades of extreme wave and wind loading. In many locations, shallow bedrock
makes traditional soil-embedded anchors unsuitable. Rock-socketed anchors, drilled into
bedrock and bonded with grout, offer a promising solution. However, their long-term
performance under offshore cyclic and multi-directional loading remains poorly understood.
This PhD project will investigate the behaviour and design of rock-socketed anchors
through a combination of laboratory experiments and advanced numerical modelling.
Laboratory experiments will explore anchor response under representative loading conditions,
while simulations will provide a framework for predicting long-term performance. By
integrating experimental and numerical approaches, the research will generate new insights
into the mechanisms, design methods, and reliability of rock anchors. The outcomes will
directly support the cost-effective deployment of floating offshore wind and wave energy
systems on Ireland’s west coast and beyond.
