    Annex IV - Investigating Environmental Effects of Wave and Tidal Devices Through International Cooperation
    Copping, Andrea; Hanna, Luke; Battey, Hoyt (2014-04)
    The pace of development for marine energy projects worldwide continues to be hindered by uncertainty surrounding potential environmental effects of wave and tidal devices and the balance of system. In response to this continued uncertainty, member nations of the Ocean Energy Systems (OES) developed a collaborative project – Annex IV – to increase collection and sharing of knowledge, research collaborations around high priority environmental interactions, and relevancy of the information to permitting (consenting) processes. The culmination of Annex IV Phase 1 is a searchable database of current literature and reports on environmental effects of marine energy development, and an analysis of three key interactions of devices and the marine environment.

    Array Optimization for Tidal Energy Extraction in a Tidal Channel – A Numerical Modeling Analysis
    Yang, Zhaoqing; Wang, Taiping; Copping, Andrea (2014-04)
    This paper presents an application of a hydrodynamic model to simulate tidal energy extraction in a tidal dominated estuary in the Pacific Northwest coast. A series of numerical experiments were carried out to simulate tidal energy extraction with different turbine array configurations, including location, spacing and array size. Preliminary model results suggest that array optimization for tidal energy extraction in a real-world site is a very complex process that requires consideration of multiple factors. Numerical models can be used effectively to assist turbine siting and array arrangement in a tidal turbine farm for tidal energy extraction.

    Methodology for Design and Economic Analysis of Marine Energy Conversion (MEC) Technologies
    Neary, Vincent S.; Lawson, Michael; Previsic, Mirko; Copping, Andrea; Hallett, Kathleen C.; Labonte, Alison; Rieks, Jeff; Murray, Dianne (2014-04)
    This paper presents results of the Reference Model Project (RMP), which began five years ago to facilitate Marine Energy Conversion (MEC) technology development and market acceleration. The four Reference Models presented herein are point designs of common MEC technology archetypes that allowed the benchmarking of technical and economic performance, and the identification of knowledge gaps, cost drivers, and cost reduction pathways that require further research and development. This project generated detailed CAD (SolidWorks) geometry files for each point design along with physical model data sets. In December 2013, Sandia National Laboratories launched a public website at http://energy.sandia.gov/rmp, which serves as a data clearing house for other MEC researchers and developers to access all supporting design documents, SolidWorks geometry files, LCOE estimation spreadsheets, and experimental data sets.
