Structural Performance of a Floating Breakwater for Different Mooring Line Typologies

Abstract

In the current study, the effect of mooring line typology and layout upon the structural behavior of a floating breakwater (FB) is studied. Different elastic anchor stiffness levels and initial pretensions were analyzed to improve knowledge of mooring lines and module connectors as well as of the structural performance of FBs as a whole. For this purpose, mooring line forces together with the stress and momentum between modules have been measured using one-dimensional and three-dimensional strain gauges. Furthermore, three-dimensional tests with different incident wave angles were carried out. The results were applied to the design of the installation of a FB at Aguete Port (Pontevedra, Spain).
