Abstract
The renewable energy sector is strategically focused on mitigating risks associated with tidal energy converters to lower the cost of tidal energy to allow it to become a significant contributor to the renewable energy mix. In this study, dynamic testing was used to assess the structural performance of a next generation helical crossflow tidal turbine foil made with carbon fibre prepreg composite material. Utilizing a Laser Scanning Vibrometer (LSV) expedites testing and data processing. A 5- metre foil prototype underwent dynamic testing in accordance with DNVGL-ST-0164 and IEC DTS 62600-3 standards. Two dynamic testing setups, with and without an unbalanced rotating mass system, were conducted before and after a series of static and fatigue tests. The research highlights the impact of altering tidal turbine system mass on dynamic response, offering crucial insights for designers. This study establishes the groundwork for a standardized LSV testing protocol for small to large scale tidal turbines, contributing to the optimization of next generation designs and performance. Ultimately, it paves the way for more efficient and sustainable marine energy solutions in the future.
