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 wave energy in Oregon : predicting wave conditions and extracted power

Creator:: Oskamp, Jeffrey A.
Abstract:: Knowledge of wave conditions in nearshore regions supports the development of ocean wave energy technology by providing wave climatology for device design considerations, and power output estimates. By modeling wave transformation over the continental shelf, wave conditions were predicted in nearshore regions where potential wave energy conversion sites are located....

Flow visualization for wake formation under solitary wave flow

Creator:: Seiffert, Betsy Rose
Abstract:: The use of data extracted from particle image velocimetry (PIV) along with vector and tensor visualization techniques provides a valuable tool for understanding a complex flow field. By studying a simple geometric structure such as a cylinder under a simple transient waveform, fundamental mechanisms of wake development under solitary wave...

Evaluation of the performance of a taut-moored dual-body direct-drive waveenergy converter through numerical modeling and physical testing

Creator:: Elwood, David E.
Abstract:: With energy prices rising and increasing concern about the influence of fossil fuels on climate change, wave energy systems are on the verge of commercial implementation. These first generation wave energy converters utilize either pneumatics or hydraulics to convert the mechanical energy of waves into electricity. For the last several...

Organizational factors in the reliability assessment of offshore systems

Creator:: Biondi, Esteban L.
Abstract:: The reliability of ocean systems is dependent on organizational factors. It has been shown that low probability / high consequence system failures are overwhelmingly induced by organizational factors. However, no methodology is yet widely accepted for the evaluation of this phenomenon or its accurate quantification. A qualitative complementary approach is...

The static and cyclic pullout behavior of plate anchors in fine saturated sand

Creator:: Petereit, Ralph A.
Abstract:: Anchors resistant to tensile loads are commonly used in civil engineering practice. Anchors in the marine environment are most frequently used for the mooring of vessels. Only recently, with the expansion of the offshore industry, has the need to develop more reliable anchor systems become necessary. Embedded plate anchors are...

Hydrodynamic forces on a horizontal cylinder under waves and current

Creator:: Teng, Chung-chu
Abstract:: By assuming the linear superposition principle to be valid, the hydrodynamic forces on a horizontal cylinder under waves and current are examined. In this study, towing a cylinder in waves is used to simulate a cylinder under waves and current. The experimental technique is proved valid through theoretical considerations and...

Finite amplitude deep water waves : a comparison of theoretical and experimental kinematics and dynamics

Creator:: Jensen, Robert E.
Abstract:: Problems associated with quantification of deep water wave kinematics and dynamics are examined. Summaries of Stokes' theory and Dean's stream function theory are reported. A computer algorithm is developed to solve the hydrodynamic characteristics for Stokes' fifth and third order and linear theories. Tests are initiated to verify the results...
