CRIMSON Project: Full-scale Turbine Demonstration By Tank Tests

The results of demonstration tests of a full-scale hydrokinetic turbine for river and tidal sites, are presented at the conclusion ofthe EU-funded CRIMSON project.The turbine features a 3-bladed crossflow, 9.0 m2 capture area rotor, representing one module of the ORPC RivGen(c) technology. A comprehensive matrix of operational trials was performed to characterize the turbine hydrodynamic performance and the efficiency of the power conversion system. An advanced blade structural monitoring equipment based on fiber-optics strain sensors was implemented and validated.The full-scale turbine tests were carried out at the hydrodynamics testing infrastructure at the Institute of Marine Engineeringof the Italian National Research Council (CNR-INM). This facility, among the largest of its kind globally, provided fullycontrolled and repeatable conditions that allowed to deliver a high-quality dataset on system performance and realiability, contributing to develop new knowledge for the enhancement of hydrokinetic turbine technology.
