This report describes the efforts at Naval Ocean Systems Center to design, fabricate and evaluate the Tethered Float Breakwater (TFB) Near-Shore Ocean Model. It provides all basic engineering information from functional concept to on-site emplacement of a full-scale model. Preliminary experiments by Scripps Institution of Oceanography established that cylindrical tethered floats, in a particular breakwater geometry, would provide an optimum wave-height reduction of up to 50 percent for a shallow-water, near-shore application. Fabrication proceeded on two three-component modules including floats, tethers and ballast assembly. This was followed by interim tests and evaluation of ballasting, surfacing and towing characteristics. Finally, the two TFB modules were towed to a near-shore test site and evaluated through three phases: initial installation, realignment at 90 degrees to shore and transfer to a new near-shore site. This report concludes with basic engineering design recommendations, while a performance evaluation continues and is not provided here. (Author)
