Underwater acoustic measurements of the WET-NZ device at Oregon State University’s ocean test facility

Creator:: Haxel, Joseph
Abstract:: Potential impacts from sound transmitted by wave energy conversion (WEC) devices on marine ecosystems are not well understood and remain an important environmental concern for the developing marine hydrokinetic renewable energy industry. On August 22, 2012 the Northwest National Marine Renewable Energy Center (NNMREC) began a test deployment of a...

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...

Testing the effectiveness of an acoustic deterrent for grey whales along the Oregon Coast

Creator:: Lagerquist, Barbara, Windsor, Martha, and Mate, Bruce
Abstract:: This study was conducted to determine whether a low-powered sound source could be effective at deterring gray whales from areas that may prove harmful to them. With increased interest in the development of marine renewal energy along the Oregon coast the concern that such development may pose a collision or...

Finding and Optimal Placement Depth for a Tidal In-Stream Energy Conversion Device in an Energetic, Baroclinic Tidal Channel

Creator:: Kawase, Mitsuhiro, Beba, Patricia, and Fabien, Brian C.
Abstract:: Hypothetical power dissipation by a tidal in‐stream energy conversion device was calculated for Admiralty Inlet, Washington, a highly energetic entrance channel to Puget Sound and currently a candidate for tidal energy development. Power dissipation was calculated for a device of a given capacity as a function of hub height above...

Is wave energy comparatively sustainable in Oregon?

Creator:: Yin, Yao
Abstract:: This essay provides a snapshot of sustainability and acceptability of wave energy and eight other electricity-generating energy sources in Oregon. Since “sustainability” is an important point of view in decision-making, the paper is centered around the concept. Although there is no consensus on the definition of sustainability in the academic...

Wave Energy Converter Modeling in the Frequency Domain : A Design Guide

Creator:: Bosma, Bret, Zhang, Zhe, Brekken, Ted K. A., Özkan-Haller, H. Tuba, McNatt, Cameron, and Yim, Solomon C.
Abstract:: Wave energy converter research continues to advance and new developers are continuing to emerge, leading to the need for a general modeling methodology. This work attempts to outline the design methodology necessary to perform frequency domain analysis on a generic wave energy converter. A two-body point absorber representing a generic...

Rigid-Object Water-Entry Impact Dynamics: Finite- Element/Smoothed Particle Hydrodynamics Modeling and Experimental Validation

Creator:: Challa, Ravi, Yim, Solomon C., Idichandy, V. G., and Vendhan, C. P.
Abstract:: A numerical study on the dynamic response of a generic rigid water-landing object (WLO) during water impact is presented in this paper. The effect of this impact is often prominent in the design phase of the re-entry project to determine the maximum force for material strength determination to ensure structural...

An Efficient Three-Dimensional FNPF Numerical Wave Tank for Large-Scale Wave Basin Experiment Simulation

Creator:: Nimmala, Seshu B., Yim, Solomon C., and Grilli, Stephan T.
Abstract:: This paper presents a parallel implementation and validation of an accurate and efficient three-dimensional computational model (3D numerical wave tank), based on fully nonlinear potential flow (FNPF) theory, and its extension to incorporate the motion of a laboratory snake piston wavemaker, as well as an absorbing beach, to simulate experiments...

Public perceptions of wave energy on the Oregon coast

Creator:: Hunter, Daniel A.
Abstract:: Oregon’s coastal communities grew from the booming logging and fishing industries of the 19th century, but in recent decades have faced not only major declines in both timber and fish resources but also an increasing reliance on tourists and retirees and the resultant glut of seasonal service-sector jobs. As a...
