The design, construction, and testing of the Lockheed rough water disk-drum oil recovery system for USCG use is detailed. The unit is 27 ft wide, 24 ft long, 8 ft high, has a 20-in waterline and weighs 14,070 lb. Design is for unmanned operation within a pool of spilled oil contained within a moored barrier. Continuous operation is feasible in sea states to 4, with winds less than 20 kn and currents less than 2 kn. Remote control is provided by a 330-ft unbilical and a 300-ft transfer hose; a tending vessel is positioned greater than 200 ft from the spill. Oil slicks 0.01 in thick can be recovered; oil-to-water content of recovered liquid usually exceeds 19:1. Peak effectiveness is in the viscosity range typical of crude oils and their emulsions. Up to 1,060 gpm of 3.5-8n, 1,500-cSt oil can be recovered in a 2-kn current using 3 of 4 transfer pumps. The unit survives tow at 8 kn in 41-kn winds and 16-ft seas.
