Five anchor design concepts were explored in conjunction with the program to develop an improved deep sea mooring capability. The knowledge gained from study of these anchor concepts, Free-fall, Pulse-jet, Explosive, Padlock, and Vibratory are summarized in this report. The vibratory anchor is currently the center of the deep sea anchoring development effort. A first generation design has demonstrated the concept to be feasible. Tests have shown that improvements are required for the vibratory anchor. An analytical study was performed to assist in optimizing a second generation design. Improvements incorporated in the second generation design will be based on information from tests of the first design and the analytical study. The improved design will be tested in a range of seafloor sediment types and water depths to rate its capabilities and establish its reliability. Author
