TEST AND EVALUATION OF UNDERWATER MATEABLE HYDRAULIC QUICK DISCONNECTS FOR USE IN DIVER TOOL SYSTEMS

摘要

The Civil Engineering Laboratory has been investigating hardware and techniques that allow the diver to connect and disconnect hydraulic tools underwater in order to use several tools during a single dive. Two commercially available non-air including couplings were tested and evaluated for use as underwater mateable hydraulic quick-disconnect couplings. Tests were conducted at 1-foot, 35-foot, and 75-foot depths. It was found that both non-air including couplings met or exceeded the performance requirements established for underwater mateable hydraulic connectors.
