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 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 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 TidGen Power System generates emission-free electricity from tidal currents and connects directly into existing grids using smart grid technology. The power system consists of three major subsystems: shore-side power electronics, mooring system, and turbine generator unit (TGU) device. This submission includes a technical report on control system development, supporting simulations and supervisory control and data acquisition (SCADA) system requirements. Also included is the final design of the control and SCADA system, with supporting simulations and risk mitigation control strategies to address major system technical risks.

The TidGen Power System generates emission-free electricity from tidal currents and connects directly into existing grids using smart grid technology. The power system consists of three major subsystems: shore-side power electronics, mooring system, and turbine generator unit (TGU) device. This submission includes the technical report on deployment and mooring system design requirements and subsystem risk analysis. A primary goal of the Advanced TidGen Power System project is to adapt ORPC's buoyant tensioned mooring system (BTMS) to the Advanced TidGen turbine generator unit (TGU). The TGU, as determined at the System Definition Review held in June 2017, is a dual-driveline, stacked system that implements hydrodynamic improvements for turbine design, turbine-turbine interactions and turbine-structure interactions. A major challenge for mooring and deployment system design will be to account for the substantial increases in loading incurred from increased power production and the resulting system drag during operation. Figure 1 shows the current system as presented for the Preliminary Design Review held in October 2017. This document addresses major risks, preventative measures, and mitigation strategies that have influenced this design and continue to drive development work toward the next design iteration. Also included is the technical report on mooring system design, supporting analytical models, and subsystem FMEA. Maine Marine Composites (MMC) has developed a simulation model to design a mooring system for Ocean Renewable Power Company) TidGen tidal energy converter. This document describes the simulation model, results, and the status of the current mooring system design. A preliminary anchor design is also proposed by MMC. The anchor is primarily a concrete gravity anchor. Structural steel is embedded inside the concrete to provide strength for the chain connection points. Steel L Channels also protrude underneath the concrete to act as a skirt to provide additional resistance.
