  • Hydrodynamic contact/impact modeling and application to ocean engineering problems

    Creator:
    Challa, Ravi
    Abstract:
    Fluid-structure interaction (FSI) is a very interesting and challenging multi-disciplinary field involving interaction of a movable or deformable structure with an internal or surrounding fluid flow. FSI has several practical engineering applications such as the determination of the hydrodynamic forces on a structure or the dynamics of motion of bodies...

  • Wave field patterns generated by wave energy converters

    Creator:
    McNatt, J. Cameron
    Abstract:
    The eventual deployment of wave energy converters (WECs) on a commercial scale will necessitate the grouping of devices into arrays or "wave farms," in order to minimize overhead costs of mooring, maintenance, installation, and electrical cabling for shoreward power delivery. Closely spaced WECs will interact hydrodynamically through diffracted and radiated...

  • Toward a more ethical engineering : four habits of highly ethical engineering practice

    Creator:
    Sugie, Masayuki Luke
    Abstract:
    In this thesis, I conduct an analysis of paradigmatic background assumptions deployed in engineering decision-making processes, in order to understand how these assumptions, operating tacitly and in tension with each other, contribute to decisions that are ethically less effective and less substantial than they would otherwise be. I do so...

  • A remotely operated, autonomous wave energy converter system

    Creator:
    Lewis, Timothy M.
    Abstract:
    The potential for electric energy generation from ocean waves is substantial and much research is being conducted on the conversion process as a renewable, grid-connected, power source. Some of the same attributes that make wave energy harvesting attractive as a grid-connected source also make it attractive as a remote, or...

  • GOSEP: Georeferenced Oregon Soil Engineering Properties

    Creator:
    Dutille, Victoria L.
    Abstract:
    Geotechnical engineers design and analyze the interface between the natural and built environments, often based on uncertain and inherently variable data due to the nature of the building material, soil. Engineers must estimate the subsurface conditions at a site using historical, in-situ, and laboratory testing data. However, only discrete representative...

  • Time-domain modeling of heaving point absorber wave energy converters, including power take-off and mooring

    Creator:
    Ruehl, Kelley
    Abstract:
    Wave energy conversion is still in its infancy, and in order for it to become a commercially viable technology, developers, investors and utilities need to estimate a Wave Energy Converter's (WEC's) performance for the wave climate of a potential installation site. With the goal of estimating a design's power output...

  • Modeling, simulation, and analysis of two hydraulic power take-off systems for wave energy conversion

    Creator:
    Casey, Sean (Sean Michael)
    Abstract:
    Hydraulic power take-off (PTO) systems have been implemented in several wave energy converter (WEC) designs in recent years. Two popular hydraulic PTO configurations coupled to a point absorber hydrodynamic model are simulated in waves representative of an energetic sea state likely to be found in deep waters off the coast...

  • Engineering a Profiling System for a Robotic Oceanographic Surface Sampler

    Creator:
    Shannon, Robert J.
    Abstract:
    ROSS (Robotic Oceanographic Surface Sampler) is an autonomous boat, equipped with oceanographic sensors, used for studying the ocean’s surface. One of its advantages over traditional research vessels is its ability to sample near glaciers, an area too dangerous for manned ships. In order to properly ascertain deep ocean heat’s effect...

  • Experimental Validation of the Hydrodynamic Coefficients for an Oscillating Water Column Wave Energy Converter

    Creator:
    Bentivoglio, Marine M. J.
    Abstract:
    Resulting from the action of wind over open water surfaces, water waves contain colossal amounts of energy that has not yet been harnessed. Seen as a very promising source for renewable energy generation, many studies have tried to make wave energy a cost competitive source by investigating optimal designs of...

  • Analysis of pressure variations observed at the ocean bottom during the 2003 Tokachi-Oki earthquake

    Creator:
    Li, Wenwen
    Abstract:
    Most tsunami studies have been conducted based on the incompressible fluid theory. However water compressibility must be considered for the process of tsunami generation by bottom displacements during submarine earthquakes. During the 2003 Tokachi-Oki earthquake, the ocean-bottom pressure variations were registered by the pressure gauges PG1 and PG2 located right...
