This site-wide search returns results for all documents and events in Tethys Engineering, prioritizing the best matches. Partial word matches are returned (e.g. "engineer" finds "engineering"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys Engineering features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

… We develop a model formulation based on Mean-Variance portfolio theory to identify the optimal site locations for a given number of wind, wave, and ocean current turbines subject to constraints on their energy collection system and the maximum number of turbines per site location. A model relaxation is also developed to improve the computational efficiency of …

Tidal stream turbines are subject to large hydrodynamic loads, including those induced by extreme waves. Scale model testing in the laboratory plays an important role in ensuring that full scale tidal turbines are designed and operated in a manner that is appropriate for harsh ocean environments where waves and tidal currents coexist.
For the first time, a fully-instrumented scaled…

This chapter talks about marine energy capturing. It introduces the physics of ocean waves and tidal streams as a prelude to explaining the principles underlying some of today's most promising developments. Wave measurement buoys are used by marine energy organisations to provide the continuous, long‐term, data required by wave energy developers as they deploy their machines offshore. Wave…
