PO218: Load–displacement behavior of anchors for characterizing mooring line response in floating offshore wind systems.
Raúl Guanche-García, Associate Professor, Polytechnic University of Madrid (UPM)
Abstract
This work presents a comprehensive investigation into the load–displacement behavior of offshore anchors, with particular emphasis on plate anchors and suction anchors, both widely used in floating offshore wind applications. The study aims to understand how the mechanical response of these anchoring solutions impacts overall behavior of mooring lines, using numerical modeling through finite element software PLAXIS. By integrating soil–structure interaction analyses with representative offshore environmental and loading conditions, the research highlights the critical role of anchor typology and seabed characteristics in ensuring safe and efficient operation of floating offshore wind systems. The research focuses on two main objectives. The first examines the performance of plate and suction anchors, which differ in geometry, installation, and mechanical behavior, under a semi-submersible floating platform loading scenario and a representative offshore soil profile. The second investigates how variations in seabed properties, including stiffness and shear strength, influence anchor response, affecting both displacement and resistance under typical operational loads. As a reference case, a 10 MW semi-submersible platform, tested numerically and experimentally within the TRL+ project, is adopted. Laboratory data from this platform define realistic loading conditions for simulations. Soil–structure interaction is analyzed through PLAXIS, applying loading schemes derived from experimental data of the 10 MW semi-submersible platform, replicating critical engineering scenarios. This methodology enables robust comparison between anchor types and soil profiles, revealing key parameters that govern anchor efficiency and their influence on mooring line dynamics. The results provide insights into the interplay between anchor design, seabed variability, and mooring system stability. By identifying the main drivers of anchor performance, the study contributes to developing more reliable design methodologies for offshore anchoring systems. These findings help make floating offshore wind systems safer, more flexible, and cost-effective in different seabed conditions, highlighting the importance of reliable anchoring for sustainable renewable energy.
