  • Testing of wave energy converters using the Ocean Sentinel Instrumentation Buoy

    Creator:
    Lettenmaier, Terrance
    Abstract:
    Ocean testing of Wave Energy Converter (WEC) prototypes is necessary to facilitate commercial WEC development. The Ocean Sentinel Instrumentation Buoy, completed in August 2012, provides a stand-alone load for WEC prototypes during ocean testing. The first part of this work was to develop the power conversion and data acquisition equipment...

  • Analysis of a two-point mooring for a spar buoy

    Creator:
    Dominguez, Richard Frank, Nath, John H., Neshyba, Steve, and Young, David A.
    Abstract:
    Recent activity in the exploration and development of the ocean's resources has created a need for scientific and technical knowledge in many areas. One example is the need for rapid and reliable techniques for ascertaining and for the predictions of sea state and the atmospheric conditions at particular ocean locations....

  • Dynamics of single point ocean moorings of a buoy--a numerical model for solution by computer

    Creator:
    Nath, John H.
    Abstract:
    A numerical model was developed which predicts the dynamic response of a single mooring line and a buoy of forty feet diameter to sinusoidal waves, wind and current in all deep waters. All forces and reactions were considered to be in one plane. The basic equations for the mooring line...

  • Optimizing ballast design of wave energy converters using evolutionary algorithms

    Creator:
    Colby, Mitchell
    Abstract:
    Wave Energy Converters (WECs) promise to be a viable alternative to current electrical generation methods. However, these WECs must become more efficient before wide-scale industrial use can become cost-effective. The efficiency of a WEC is primarily dependent upon its geometry and ballast configuration which are both difficult to evaluate, due...

  • Use of on-line computers in environmental research

    Creator:
    Burt, Wayne V.
    Abstract:
    A real-time data acquisition/central system has been developed for environmental monitoring and research. The basic elements of the system are a large instrumented spar buoy, a computer which controls data acquisition through a telemetry link and simultaneously files and analyzes the data, and the investigator who prescribes appropriate sets of...

  • 1970 Totem wind and current data

    Creator:
    Plutchak, Noel B. and THEMIS Group
    Abstract:
    First-order analyses of wind and current time series obtained from a Totem buoy off the Oregon coast during 1970 are presented. In addition, winds at Totem are compared with winds recorded simultaneously at New­port, Oregon.
