Collaborative effort between AquaHarmonics, Sandia National Laboratories (SNL), and the National Renewable Energy Laboratory (NREL) to revise and validate Aquaharmonics' full wave to wire model, allowing for reduced uncertainty and increased understanding of design requirements of a utility scale wave energy converter (WEC). SNL and NREL in collaboration with AquaHarmonics, will set up and run WEC Simulator (WEC-Sim) models of the AquaHarmonics WEC, building off past model developments for inclusion of custom PTO (power take-off) dynamics. The intent is to review, update, and verify or validate a new WEC-Sim model against wave tank experimental data. Furthermore, the WEC-Sim model will be coupled to an energy storage system model to better understand the wave-to-wire functionality. Project is part of the TEAMER RFTS 2 (request for technical support) system of WEC research projects. Testing data can be found in the associated MHKDR link below.

This dataset supports the concept verification of the Dual Inclined Paddles Wave Energy Converter (WEC), a small-scale marine hydrokinetic device developed by E-Wave Technologies LLC for offshore aquaculture applications. The review was conducted by the American Bureau of Shipping (ABS). The system consists of dual inclined paddles retrofitted to a buoy, connected to a tether-based power take-off (PTO) system. Verification was based on engineering analysis and 1:8 scale model testing at Stevens Institute of Technology. Included documents comprise a System Requirements and Description Document (SRDD), a risk assessment, and ABS review comments with responses. The documents define system architecture, performance criteria, environmental conditions, and applicable standards. The review is limited to concept verification and does not cover full-scale performance.

Software developed in LabVIEW for the Modular Ocean Instrumentation System (MOIS) is provided. Two documents: MOIS User's Guide and MOIS Software Developer's Guide are included in the submission.

Laminar Scientific's patented nearshore seesaw wave energy converter has several features assessed in this study utilizing the Wave Energy Converter SIMulator (WEC-Sim) Facility. One of these features is the ability to change spacing between two spherical floats of the seesaw to adjust to different sea-states and maximize rotational motion produced at the pivot. Conversely, severe wave conditions would warrant the minimization of rotational motion by minimizing float spacing. This study tested the hypothesis that the seesaw wave energy converter (WEC) can generate out-of-phase behavior between its fore and aft floats and that spacing adjustments will lead to improved power capture across a range of sea-states. This directory contains: - all Capytaine models, results, and visualization scripts (bemio.m) for the two-float configuration - slides shared during the biweekly updates, the final test plan and the final post-access report - all Capytaine models, results, and visualization scripts (bemio.m) for the tri-float configuration - all the WEC-Sim input files, models, test cases, results, visualizations, plots for the two-float configuration Post access report and GitHub repository reflecting the work done under the TEAMER RFTS 9 (request for technical support) award.

This dataset includes data from the Monterey Bay Aquarium Research Institute (MBARI) wave energy converter (WEC) and a nearby located Sofar Spotter buoy. The Monterey Bay Aquarium Research Institute has developed and deployed a small two-body point absorber wave energy device suitable to autonomous underwater vehicle, sensor system, and even aquaculture farm needs. For more information on the MBARI WEC see the research journal attached in the submission.

This dataset contains experimental results from testing the Halona wave energy converter (WEC) in both fixed and floating configurations. This dataset reflects a 1/10th scale omnidirectional spar buoy oscillating water column (OWC) device, designed to improve platform stability for autonomous underwater vehicle (AUV) docking. Tests were conducted at the O.H. Hinsdale Wave Research Laboratory's Directional Wave Basin, replicating field conditions anticipated for a full-scale deployment at Kilo Nalu, Oahu. The experiments included unidirectional and directional wave conditions, spanning regular and irregular waves, with varying power take-off (PTO) damping settings represented by different orifice plates. Data collected include differential pressure across orifice plates, six-degree-of-freedom motion capture, surface elevation, and mooring tension forces, with units clearly labeled and standardized. Data products include pressure, surface elevation, mooring tension, and PhaseSpace Motion response data, as well as normalized Response Amplitude Operators (RAOs), normalized chamber pressures, and capture efficiencies. Data are provided below in the zip files, with 'RNG' and 'Reg' identifiers for irregular and regular wave tests respectively, and are labelled with alpha values (percentage relating to opening ratio). Comprehensive MATLAB scripts for data analysis and figure generation are included. The tests support validation of OpenFOAM and ProteusDS models. Use of the dataset assumes familiarity with wave energy converter testing, MATLAB software, and standard hydrodynamic modeling practices. Results from this testing are detailed in publications by Ulm, Huang, and Cross (2023, 2024, and 2025). A Post Access Report summarizing the experimental methods and findings is also attached.

This submission includes documentation on the Modular Ocean Instrumentation System (MOIS) installation on the Azura 1/2 scale wave energy converter at the Marine Station Kaneohe Bay (MCBH). Data from the deployment will be uploaded over the course of the test. The instrumentation and data come from the NREL team participating in this testing.

This submission from AMEC (the Atlantic Marine Energy Center) includes data from an ocean field deployment of a wave powered water pump in March 2023. The wave pump is an upweller device, designed to enhance macroalgal aquaculture. The wave pump device was deployed off the coast of Isles of Shoals Appledore Island in Maine, USA. The data were collected using a custom-built DAQ module comprised of Arduino Unos. GPS time stamp accompanies the data. The data are volumetric flow rate from the wave pump, and relative motion of the device between float and spar buoys. Flow rate is measured by flow meter, and relative motion is measured by lidar. Calibration data for the lidar and flow meter sensors are included. This data set also includes synchronous Sofar Spotter buoy data from a mooring approximately 300 feet away from the wave pump mooring. Video data from the deployment are included from both on-board the device sporadically throughout the deployment, and from a webcam for a short duration of the deployment. Hydrophone data were also taken co-currently, and are available by contacting Martin Wosnik at the University of New Hampshire. The Matlab code used to process the field data is incorporated. A biological assessment is included which aided the NEPA consultation process, prior to conducting the field deployment. A WEC-Sim numerical model of the wave pump, and a re-design effort are part of this work. Code used to validate the WEC-Sim model from the field data are also included.
