The objective of this study was to investigate the feasibility of combining propellant-activated embedment anchors and a structural frame with bearings pads to provide a fixed-point, deep ocean anchorage system. The work was to include the conception, design, fabrication, and evaluation. This report describes the resulting device, termed PADLOCK, discusses its development, and documents the field tests and results. Essentially the PADLOCK is a tripodal frame terminating in 6-foot-diameter bearing pads that are locked to the sea floor through activation of 20,000-pound nominal holding power embedment anchors, one per bearing pad. Shallow water tests demonstrated that the components are operationally compatible as a system and that the embedment anchors can be detonated singly or as a group. A limited number of tests showed the reliability of the complete system to be low, mainly because of the performance of the embedment anchors. Author
