PROPELLANT-ACTUATED DEEP WATER ANCHOR. INTERIM REPORT

A propellant-actuated deep water anchor is being developed to moor deep ocean surface and sub-surface structures. The anchor is designed to have a long-term holding capacity of 20,000 pounds and function in seafloors ranging from very soft sediments to hard rock (basalt) in water depths to 20,000 feet. The anchor has been designed, fabricated, and tested on land. Deep water use of this anchor requires that it be expendable; therefore, surplus ammunition components are used in the launching system (e.g., gun barrel, cartridge, primer), and a simplified structural shape is used for the reaction vessel. Three anchor flukes (one for rock and coral, one for sand and stiff clay, and one for soft clay) were designed to satsify the realm of seafloor anchoring possibilities. (Modified author abstract)
