This project focused on developing an automated workflow to evaluate and optimize the iProTech Pitching Inertial Pump (PIP) wave energy converter (WEC) using open-source Python packages and the MATLAB/Simulink tool, WEC-Sim. The process involved parameterizing key design variables, running time-domain simulations, and performing sensitivity analyses to determine their impact on power output. The workflow, designed for the PIP device, is generalized and can be extended to optimize other WECs that can be simulated in WEC-Sim. This work establishes a foundation for future time-domain-based WEC design optimizations. Included in this submission are all figures from the final report and the model inputs required to generate them. This includes Python scripts with inputs that produce the meshes, boundary element method (BEM) models, hydrodynamic coefficients, and the WEC-Sim models used for time-domain analyses. Although data for every single run is not included to save space, all of it can be reproduced using the provided models. Detailed instructions for setting up the environment and running the codes are also included.

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.

The CFD (computational fluid dynamics) results for the Mass of Water Turbine (MOWT) current energy converter from MWNW Consulting (formerly Ecosse IP). Each case is self-contained in its own tar.gz archive file. The archive contains the scripts required to perform a full simulation using OpenFOAM v1906. The scripts to process the output and plot forces are included in "Plotting Scripts", and all computational meshes generated are included in "Computational Grids". Project is part of the TEAMER RFTS 2 (request for technical support) program.

This dataset comprises of raw numerical simulation data conducted on a novel nearshore at-surface wave energy converter (WEC). The testing aimed and was intended to provide a calibration then optimization regime through numerical analysis. This project is part of the TEAMER RFTS 10 (request for technical support) program. This data builds upon the research and publication carried out in RFTS 4 regarding a unique half submerged, biconcave buoy that extracts surge and heave motions, but with further modifications that allow for a low number of moving parts, a passive severe force protection system and a more manufacturable design. To produce this raw data, Laminar Scientific Inc. worked with AMOG Consulting to carry out numerical analysis to analyze the performance of the concave buoy, novel nearshore at-surface WEC, analyze sensitivities to varied damping coefficients and stiffness, along with testing the different configurations of the severe force protection system. This subset of data provides the raw data and scripts used through multiple phases of the project as specified through the scope of work stated in the report (TEAMER-Laminar_AMOG Test Plan Report). The Test Plan Report will be attached once available. The folders provided are as follows: - Calibrated_Model_Phase - Sensitivity_Model_Phase - Final_Model_Normal - Final_Model_Capitulated - Final_Model_Extended_Scope In the folders, there consists of raw data in .csv files with names specified as nm2023.j517_###_Model.001.#.##.Time_Histories_FM#.csv (see included README File for more information).These files are named according to the model phase, WEC orientation, wave height and wave period specific to its respective model phase wave matrix and comparing file. In each csv., data that was deemed necessary for the conduct of the project are labeled with units in SI. Accompanying each iteration folder, there provides a Julia Script that was used to create the plots used in the final report.

Project and generator specifications and initial prototype test data for flap-type wave energy converters (WEC)

A report on state estimation for advanced control of wave energy converters (WECs), with supporting data models and slides from the overview presentation. The methods discussed are intended for use to enable real-time closed loop control of WECs.

Numerous studies have shown that advanced control of a wave energy converter's (WEC's) power take off (PTO) can provide significant increases (on the order of 200-300%) in WEC energy absorption. Transitioning these control approaches from simplified paper studies to application in full-scale devices remains an open and extremely challenging problem will be central to creating economically competitive WECs and delivering clean renewable energy to the US electrical grid. The Advanced WEC Dynamics and Controls project is targeted on assisting WEC developers to apply novel control systems for their devices and thus achieving major increases in performance and economic viability. The success of any control strategy is based directly upon the availability of a reduced-order model with the ability to accurately capture the dynamics of the system with sufficient accuracy. A model-scale WEC was designed and fabricated for use in studies to advance the state-of-the-art in WEC controls. This test, which is the first in a series of planned tests, focused on system identification (system ID) and model validation.

The SeaRAY is a deployable power system for maritime sensors, monitoring equipment, communications, unmanned underwater vehicles, and other similar payloads. This project is to design, deliver, and test a prototype low-power WEC that lowers the total cost of ownership and provides robust, new capabilities for customers in the maritime environment. This submission includes reports for the SeaRAY preliminary system design, integration plan, and test plan for testing at the U.S. Navy's Wave Energy Test Site (WETS), as well as the preliminary installation, operation, & maintenance (IO&M) plan.

Quarterly Technical Report for "Advanced Controls for the Multi-pod Centipod WEC device" describing project parameters, organization, task activities, accomplishments, and conclusions. See other submissions under this DOE project for economic viability, design geometry, and modeling. The purpose of this quarterly report is to release a progress report immediately, while the final report and remaining project items await release before the moratorium date.

This document describes the experiments carried out in December 2019 and February-March 2020 in the Directional Wave Basin at the O.H. Hinsdale Wave Research Laboratory, Oregon State University. Regular and irregular waves were generated in the absence and presence of a WEC, including regular and irregular waves using different wave generation and control strategies, emphasizing nonlinear wave conditions and nonlinear PTO control. Results of standard linear and 2nd-order wave generation are compared with results of a newly developed fully nonlinear wave generation technique using the Nonlinear Schrodinger (NLS) equation.
