ENGINEERING FEASIBILITY STUDY OF THE BISHOP SYSTEM FOR OPEN OCEAN OIL SPILLS

An Engineering Feasibility Study on the Bishop System indicated effectiveness for ocean operation at low cost with capability of removing all types of oil spills from ocean surface. The system consists of a buoyant apparatus, 21 feet wide, propelled ahead of a support vessel, which closely tracks the sea surface to remove the oil film. Hydraulic pumping capacity is 5000 gpm and system is capable of operating at 4 Knot speed and up to Sea State 4 at reduced speed. Calculated system effectiveness is 240 Barrels per hour for 1/16 in. thick oil film in smooth water at 4.0 Knots. System efficiency is 5 percent oil to water picked up for a 1/16 in. oil film and 100 percent for a 1 in. oil film. Cost factors for skimming 1/16 in. oil film in smooth water have been estimated at $0.50/Bbl. (Author)
