Measurements & Instrumentation

Current speed and wave measurements are critical for assessing the resource and hydrodynamic characteristics at an MHK site.  Sandia’s team has the capability and sensors/instrumentation for conducting field- and laboratory-scale measurements, such as ADCPs, ADVs, echo sounders, and a survey boat.

Wave and current energy converters withstand millions of load cycles throughout their lifetime. Mechanical and structural load measurements are essential for design validation, certification and structural health monitoring of the device. Sandia has been assisting industry partners to measure and monitor loads in both laboratory- and field-scale testing, using load cells, torque transducers, fiber-Bragg grating sensors, and distributed fiber optic sensors.
