Experimental investigation of the marine growth effect on the hydrodynamical behavior of a submarine cable under current and wave conditions
This document describes the experimental set-up of OMDYN2 and LEHERO-MG projects. The study seeks to quantify the impact of biofouing on the dynamic behavior of an underwater power cable by analysing the hydrodynamic coefficients, such as drag and added mass coefficients.
Experiments carried out in the wave and current basin of IFREMER, located at Boulogne-sur-mer, allowed us to compare the dynamics of cylinder with or without roughness. The roughness studied concerns realistic marine growth and has therefore significantly bigger dimensions (like mussels) than roughness studied in the research literature on the subject. Tests are conducted using current only then horizontal oscillating movements and finally the combination of both.
