The Detailed System Design Package for the Triton-C WEC, including a report and CAD drawings pertaining to the overall preliminary design, system arrangement, surface float hull, and surface float arrangement. D6 presents an overview of the final detailed design package for the Triton-C wave energy converter. A number of accompanying documents (D11) are provided for more detail on individual systems and subsystems. Each of these documents presents specific engineering documentation and drawings. Taken as a whole, these documents should provide a complete and comprehensive guide to the final design and construction of the Oscilla Power Triton-C WEC Prototype.
