SPECIALIZED ANCHORS FOR THE DEEP SEA--PROGRESS SUMMARY

Five anchor design concepts to develop an improved deep sea mooring capability have been examined and the performance observed during this study are summarized. The five anchor concepts are: 1) free-fall, 2) pulse-jet, 3) explosive, 4) padlock, and 5) vibratory. Although each has its own conceptual advantages and associated problems, the results of the preliminary program indicate that the vibratory anchor concept is feasible and most promising as demonstrated by a first generation design prototype. Necessary improvements are to be incorporated into a second generation design and a prototype is to be tested in a range of seafloor sediment types and water depths to rate its capabilities and establish its reliability. As a result of this initial concept evaluation, second phase efforts will be directed primarily toward developing the vibratory anchor.
