Abstract:

For the past 7 years the Navys Civil Engineering Laboratory CEL has conducted research and development on diver work systems in support of Navy seafloor construction and ship salvage. Under the sponsorship of the Naval Facilities Engineering Command and the Naval Ship Systems Command the program has progressed from the evaluation of unpowered hand tools through pneumatic and hydraulic powered tools, and diver-operated work vehicles. The current program is investigating controlled methods of excavating rock underwater. These investigations have shown that oil-hydraulic-powered equipment is best for most underwater work. Systems using seawater as a hydraulic fluid offer many potential advantages however, successful development of a practical seawater-powered motor has not yet been achieved. A variety of operational oil hydraulic power sources and compatible tools have been developed and delivered to operational Navy units.
