TigerRAY Drifting Tests and Wave Data - Lake Washington and Puget Sound, February 2023
This dataset contains measurements from drifting deployments of the TigerRAY, a two-body wave energy converter, and four SWIFT buoys on Lake Washington and Puget Sound during February 2023. Tests were conducted under varying wave conditions, including natural waves, calm conditions with artificial boat wakes, and periods of power take-off (PTO) engagement and freewheeling.
Each data file includes a MATLAB structure containing motion, pressure, load, electrical, and heading measurements from TigerRAY's nacelle, heave plate, encoders, IMUs, and pressure sensors. Additional wave data were collected by tethered SWIFT buoys. Units are labeled and described in an accompanying data guide, which also details sensor configurations, data processing steps, and deployment notes.
