Hydrodynamic Modeling of Submerged Wave Energy Converters: Power Take-Off Mooring Configuration Effect on Power Performance

Creator:: Meek, Moira H.
Abstract:: Wave energy converters (WECs) show promising potential to significantly contribute to global renewable energy goals. Numerous WEC designs have been proposed and investigated, but wave energy conversion technology has yet to reach convergence in the same way wind or solar has. Of the designs currently in existence, surface-piercing WECs are...

An Inner-Shelf Wave Forecasting System for the U.S. Pacific Northwest

Creator:: Garcia-Medina, Gabriel, Özkan-Haller, H. Tuba, Ruggiero, Peter, and Oskamp, Jeffrey
Abstract:: An operational inner-shelf wave forecasting system was implemented for the Oregon and southwest Washington coast in the U.S. Pacific Northwest (PNW). High-resolution wave forecasts are useful for navigational planning, identifying wave energy resources, providing information for site-specific coastal flood models, and having an informed recreational beach user group, among other...

Comparison and Validation of Hydrodynamic Theories for Wave Energy Converter Modelling

Creator:: Leary, Matthew M.
Abstract:: A wide variety of hydrodynamic theories are utilized to approximate a Wave Energy Converter’s (WEC) equation of motion. Numerous theories have been refined in order to improve numerical approximations of WEC dynamics. When incorporating refined hydrodynamic theories into numerical models, there are distinct impacts on WEC rigid body motions, cable...

Waves, WEC, and Arrays

Creator:: McNatt, Cameron
Abstract:: This presentation was given as part of Oregon State University's College of Oceanographic and Atmospheric Sciences graduate student seminar series. It is critical to understand waves dynamics in order to design wave energy convertors and then deploy them in arrays. Modelling suggests that array interactions lead to constructive and destructive...

2012 Annual Operations & Monitoring Report: North Energy Test Site

Creator:: Henkel, Sarah K., Haxel, Joseph H., Schultz, Adam, and Hofford, Anna
Abstract:: The first wave energy test at the Northwest National Marine Renewable Energy Center’s (NNMREC) North Energy Test Site (NETS) off the coast of Newport, OR took place in 2012 with the deployment of the WET-NZ wave energy conversion (WEC) device and the Ocean Sentinel instrumentation buoy. The WET-NZ and Ocean...

Tidal Energy Extraction in an Idealized Ocean-Fjord Tidal Model with Astronomical Forcing

Creator:: Kawase, Mitsuhiro and Gedney, Marisa
Abstract:: Abstract— A highly idealized model of an ocean-fjord system, in which the tide is forced astronomically by the gravitational force of the moon, is used to study effects of localized tidal energy extraction on regional and global tides. The modeled system is energetically complete in the sense that the model...

Characterizing dangerous waves for ocean wave energy converter survivability

Creator:: Hovland, Justin
Abstract:: Ocean Wave Energy Converters (OWECs) operating on the water surface are subject to storms and other extreme events. In particular, high and steep waves, especially breaking waves, are likely the most dangerous to OWECs. A method for quantifying the breaking severity of waves is presented and applied to wave data...

Wave Energy From Idea, to Concept, to Converter: Structuring Methods for Design and Evaluation of Wave Energy Devices

Creator:: Trueworthy, Ali May
Abstract:: The amount of energy we use and the ways that we get that energy sit on the edge of dramatic change as the carbon budget which can keep the planet under 1.5C of global average temperature increase gets smaller (Allen, 2018). In response, we continue to research and develop renewable...
