On the design of a small scale tidal converter for long time deployment at sea

Abstract

This paper presents the design of a scale model of a kite-like tidal converter, GEMSTAR, intended for long-term deployment at sea. The main objective of this experiment is to develop a digital twin with integrated fault detection and isolation capabilities to improve the reliability and performance of the system. A fully functional 1:10 scale model of GEMSTAR was designed based on extensive measurements of tidal currents at the planned deployment site. Several locations were investigated to determine the most suitable flow profiles for energy generation. This study outlines the key challenges for operational functionality and describes the selection of critical physical parameters to be monitored during deployment using onboard sensors.
