Chain and nylon mooring lines for floating offshore wind foundations: numerical modelling validation

Álvaro Rodríguez-Luis, Project Technician, IHCantabria - Instituto de Hidráulica Ambiental de la Universidad de Cantabria

Abstract

Offshore floating wind technology is called to become a commercial alternative during the following decades. The design of reliable, cheap and maintainable mooring systems is a key aspect on the path to economically feasible concepts. Steel chain catenary mooring systems are expensive and, in certain conditions, may present extreme snap loads, risking the actives. The latest introduction of hybrid mooring lines combining steel chain, clump weights and nylon rope is thought to overcome these problems, as well as deep and very deep-water challenges. However, modelling properly the new elements of these mooring lines is a challenge, given the elastoplastic properties of nylon and the need of coupling different line segments and intermediate weights or floaters. This research piece summarizes the work carried to validate a numerical model with experimental tests performed on a mooring line design with such characteristics, focused on addressing the technical challenges of this kind of mooring lines, and being part of the tasks developed for the H2020 COREWIND project.
