Advanced Anchoring and Mooring Studies

An industry knowledge base for existing anchoring and mooring techniques was established, along with providing potential solutions that eliminate or minimize the conflicts with other public and commercial users of the coastal waters including the fishing and crabbing industry.

Ambient Noise Assessment

This review study has been conducted to provide a concise knowledge base of the expected underwater noise conditions in the nearshore environment in regions of the Oregon coast where ocean energy projects could be developed and to present an overview of noise measurement methodologies that would be suitable for the effective regulatory assessment of potential acoustic impacts. This report is intended as a reference to be used by ocean energy developers in the specification and selection of approaches to underwater noise measurement that would be acceptable to regulatory bodies, consistent with the state of the industry and cost effective to implement.

Electromagnetic Field (EMF) Measurements

The major objective of this project was to demonstrate an ability to achieve affordable, reliable, repeatable Electromagnetic Field (EMF) measurement protocols in support of wave and tidal energy technology development and deployment. As such, this report was prepared to describe the prototype instrumentation fabricated with affordable and available components, calibration results to provide the basis for repeatability, and a data summary of the ambient background and energized power cable measurements conducted during at-sea measurement deployments.

Northwest National Marine Renewable Energy Center

In 2008, Oregon State University, with assistance from OWET, was awarded $6.25 million by the U.S. Department of Energy (USDOE) to develop the Northwest National Marine Renewable Energy Center (NNMREC) to facilitate the responsible development of wave and offshore wind energy in the Northwest through research, education and outreach.

Oregon Deployment Best Practices

Deployment best practices were established based on the successful deployment and recovery of the WET-NZ wave energy converter device deployed for a period of six weeks at the Northwest National Marine Renewable Energy Center’s Newport test site. Practices described focus on the WET-NZ device, it’s related mooring system and the device’s connection to the Ocean Sentinel. The WET-NZ was connected to the Ocean Sentinel via an umbilical cable to transmit power and perform various data and instrumentation experiments.

Sediment Transport Studies

Researchers initiated a baseline study of sediment transport processes in order to assess the potential effects of ocean energy devices on sediment transport and on the morphology of beaches. Core elements of the monitoring program included the measurements of the waves and currents, numerical modeling of the background ocean climate and nearshore bathymetry and shoreline observations to document the baseline conditions. The monitoring and modeling techniques developed will be useful for assessing the effects of future ocean energy devices that will be established along the Oregon coast.

WEC-array Far-field Effects Analysis

Laboratory experiments were performed using five 1:33 scale, commercially designed, point-absorber wave energy converters (WECS). Multiple array configurations were subjected to a wide range of wave conditions—both regular waves and fully-directional sea states—in order to better constrain models for simulating the environmental effects of large-scale arrays of WECs. Partnered with Oregon State University and Columbia Power Technologies.
