Abstract

A methodology to find the optimal configuration of a bottom-fixed OWC (oscillating water column) system in terms of both the extracted power efficiency and the structural response stresses is developed in this paper for regular waves. The model takes into account the environmental conditions and the material properties of the OWC as input parameters. The hydrodynamic problem is solved using an analytical model developed in Python®, whereas the structural FE model is developed in ABAQUS®. Both problems are coupled into a single computational tool to automate the simulation process. The results reveal the possibility of finding an optimal configuration taking into account the trade-off between the maximum extracted power efficiency and the minimum structural response stresses of the system, with potential implications in structural reliability and maintenance. This study opens a line of study with promising implications for the marine renewable energy applications.
