Reference Model 3 Scaled Geometry (RM3: Wave Point Absorber)

Description

Contains the Reference Model 3 (RM3) scaled scale geometry files of the Wave Point Absorber, developed by the Reference Model Project (RMP). These scaled geometry files are saved as SolidWorks assembly, IGS, and STEP files, and require a CAD program to view. The scaled RM3 device was tested at the Scripps Institution of Oceanography at the University of California at San Diego wave tank, details of which are described in the included test report. The scale of the geometries included in this submission are at a 1:33 scale compared to the full scale geometry. This data was generated upon completion of the project on September 30, 2014. The Reference Model Project (RMP), sponsored by the U.S. Department of Energy (DOE), was a partnered effort to develop open-source MHK point designs as reference models (RMs) to benchmark MHK technology performance and costs, and an open-source methodology for design and analysis of MHK technologies, including models for estimating their capital costs, operational costs, and levelized costs of energy. The point designs also served as open-source test articles for university researchers and commercial technology developers. The RMP project team, led by Sandia National Laboratories (SNL), included a partnership between DOE, three national laboratories, including the National Renewable Energy Laboratory (NREL), Pacific Northwest National Laboratory (PNNL), and Oak Ridge National Laboratory (ORNL), the Applied Research Laboratory of Penn State University, and Re Vision Consulting. Reference Model 3 (RM3) is a wave point absorber, also referred to as a wave power buoy, that was designed for a reference site located off the shore of Eureka in Humboldt County, California. The design of the device consists of a surface float that translates (oscillates) with wave motion relative to a vertical column spar buoy, which connects to a subsurface reaction plate. This two-body point absorber converts wave energy into electrical power predominately from the device?s heave oscillation induced by incident waves; the float is designed to oscillate up and down the vertical shaft up to 4 m. The bottom of the reaction plate is about 35 m below the water surface. The device is targeted for deployment in water depths of 40 m to 100 m. The point absorber is also connected to a mooring system to keep the floating device in position.

21 This report is an addendum to SAND2013-9040: Methodology for Design and Economic Analysis of Marine Energy Conversion (MEC) Technologies and describes the experimental wave tank tests conducted during the RM3 floating-point absorber (FPA) wave energy converter study. In the RM3 project, three sets of experimental wave tank tests were conducted to study FPA wave energy converter systems during both operational and extreme sea states. The first set of wave tank tests focused on a locked FPA, which did not include a power take-off system, and analyzed the hydrodynamics of an FPA during extreme wave (survival) conditions. The second and third sets of tests evaluated the FPA power output during operational wave environments. The objective of this report is to provide experimental data sets for validating numerical simulation studies of wave tank tests. The wave tank test settings, model dimensions and properties, and post-processed data sets—including the measured wave environment, hydrodynamic response, and the estimated power output—are documented https://tethys-engineering.pnnl.gov/publications/experimental-wave-tank-test-reference-model-3-floating-point-absorber-wave-energy
