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. This data set is described in the "Test Log" excel file. Please refer to that document for details on each specific test date/time, constraint parameters and model hardware setup details. Sim model can be found in the associated MHKDR link below.

This data is a result of an experimental campaign to characterize the hydrodynamics and performance of a laboratory-scale oscillating surge wave energy converter (OSWEC). The device was 85 cm wide, 1.4 meters tall, and 14 cm thick and was tested in the Sea Wave Environmental Lab (SWEL) wave tank at the National Renewable Energy Laboratory which is 2.5 meters wide with a water depth of 1.3 meters. The device included fifteen pressure sensors on the flap face, two 6-axis load cells at the hinge, an encoder to measure flap position, and a motor to emulate a PTO and absorb power. We provide a full summary of the device and experiments in the TEAMER Post-Access Report titled "Optimal control of an oscillating surge wave energy converter". This DropBox directory contains data from four types of experiments: 1. Buoyancy Tests - We measure the torque required to hold the flap at different angles to characterize buoyancy torque as a function of position. 2. Locked Flap (Excitation) Tests - We measure the torque on a locked flap subject to different wave parameters to extract the excitation torque coefficient. 3. Forced Oscillation (Radiation) Tests - We force the flap to oscillate at different periods and amplitudes to extract added inertia and radiation damping coefficients. 4. Control Tests - We subject the flap to different waves and use a linear damping controller to emulate a PTO and extract absorbed power and capture width ratio (CWR) as a function of wave and control parameters. This data set includes raw and processed time series data from the encoder and load cells, as well as calculated hydrodynamic and performance parameters from the tests. We include a README document as well as a spreadsheet with individual test details as a reference. Funding for this experimental campaign was provided by the TEAMER Program under RFTS 10 and was a collaboration between the University of Washington and the National Renewable Energy Laboratory.

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.

The Laboratory Upgrade Point Absorber (LUPA) is an open-source wave energy converter designed and tested by Oregon State University. The computer-aided design (CAD) files are provided here in two forms: the original SOLIDWORKS (2024) model as "LUPA SOLIDWORKS.zip" and as a STEP file "LUPA-A1000.step". The bill of materials is provided as an Excel file with assemblies (LUPA-Axxx), part numbers (LUPA-Axxx-Pyyy), part descriptions, manufacturers, and manufacturer part numbers. An engineering drawing is provided as a PDF of the basic float and spar geometries and mass properties. This comprehensive CAD model represents LUPA as it was deployed in Fall 2023 testing (project name: TEAMERLUPA2) at the O.H. Hinsdale Wave Research Laboratory. The mass properties, including mass, center of gravity, and moments of inertia, have been overridden for some parts and assemblies to match the physical device properties as determined from experiments. This appears as "overridden by user" when viewing mass properties in SOLIDWORKS. The LUPA-A1000.SLDASM file from the LUPA SOLIDWORKS.zip folder is the topmost assembly; open this file to see the entire model as one assembly. This model is the second published CAD model of LUPA. The first is linked below as Version 1. This second model has the following engineering changes: moved spar flotation up, added more mass to the heave plate, added the MiniDAQ to the float, and reduced the weight of the PTO pulleys. The net effect of these changes makes LUPA more hydrodynamically stable than the first version. See "PMEC Page" and the "Signature Project Page" resources below for more information on LUPA. This testing was funded by TEAMER RTFS 7. Data from this testing can be found on MHKDR at the links below.

This dataset contains software, sensor data, and experimental recordings generated during Year 3 of a DOE-funded project focused on the co-design of marine energy converters and autonomous underwater vehicle (AUV) docking and recharging systems. Data were collected during experimental testing at the O.H. Hinsdale Wave Research Laboratory and support foundational research aimed at advancing coupled Wave Energy Converter (WEC)-AUV systems for marine energy applications. The dataset includes pressure sensor recordings collected on a remotely operated vehicle (ROV) under varying wave conditions; vehicle data recorded during autonomous docking operations; and video footage from tests demonstrating AUV docking procedures. Also included is software hosted in a linked GitHub repository, which provides installation instructions, supporting code for BlueROV2 operation, and relevant dependencies for data handling and system control. This release builds on data provided in a previous submission from earlier phases of the project, linked below.

This dataset contains the full set of training materials used in a marine hydrokinetic (MHK) modeling workshop conducted by Sandia National Laboratories for the University of Alaska Fairbanks, funded through the U.S. Department of Energy's TEAMER program. The workshop focused on the use of the SNL-Delft3D-CEC and SNL-SWAN modeling tools, which simulate the hydrodynamic and environmental impacts of current and wave energy converters, respectively. The materials were developed to support the evaluation of physical and environmental interactions of MHK devices using open-source modeling frameworks. The dataset includes presentations, tutorials, theoretical documentation, and software setup instructions related to modeling wave and current energy devices. It covers both conceptual and real-world applications, such as channel flow and riverine or coastal sites like the Tanana River and Yakutat, Alaska. Instructions for installing and customizing the Delft3D and SWAN modeling suites with the SNL-developed modules are included, along with test cases and example scenarios. All data units and modeling parameters are labeled, and the dataset assumes access to proprietary software components (e.g., Deltares license files for Delft3D FM Suite) and some familiarity with hydrodynamic modeling tools.

Wave tank tests at Stevens Institute of Technology quantified the ability of near-surface platforms to concentrate wave energy over the platform. Due to the instantaneous change in water depth, mass, energy, and power are conserved in this process. The energy and power concentration factors ranged from 1 to 4 times the incident wave power as a function of incident wave period, wave height, and platform depth. Platform slope was set to zero for all 300 plus wave runs at platform top surface depths varying from 0.15 m to 1.10 m. This data set is extremely valuable to the MHK industry as water particle velocities over the platform were recorded at velocities on the order of 4x incident maximum orbital velocities based on Airy/Navier-Stokes theory. This term has been used "A change in effective water depth over which waves propagate". The only way I have been able to get the data to align with Airy wave theory is to use the top of tension leg platform (TLP) depth and a wave height corresponding to the change in the free surface elevation over the platform. The discrete change in effective water depth over which waves propagate is a topic of interest for fundamental hydrodynamic research as this implies there is an instantaneous convergence of group and phase velocities of waves at the TLP edge which shears the incident waves. This high shear rate makes the inviscid and irrotational assumptions and potential flow analysis invalid. This data set can be used as part of benchmarking any CFD which may be used to analyze this flow field. Using the top of the TLP as the "h" and full free-surface elevation change over the platform for "H", the maximum orbital velocities measured align with Airy/Navier-Stokes equations. If the tank depth is used for "h", or incident wave height is used for "H", the equations do not align with the data. Note that the SurfWEC system involves a non-inertial reference frame as the fully-submerged TLP is continuously experiencing positive and negative accelerations in most wave conditions; therefore, when a spring-mass (regenerative AHC winch - float) system is used for PTO, the "pseudo" centrifugal force must be accounted for in the loading to the system.
