[en] An oil recovery wall system has been proposed for use in Kuwait so that countries to the north and south will be protected from any future and unexpected oil spill. The system makes use of two walls, perpendicular to the shoreline, at both the northern and the southern ends of an oil refinery area. It is designed to keep spilled oil within the vicinity of the wall, preventing oil from spreading to seawater and the rest of the Gulf. The oil recovery wall contains oil-collection units which help contain oil in the event of an accidental spill at any Kuwaiti refineries. This presentation provides details of the oil-collection unit and describes laboratory-scale testing of the unit. The wall has many openings at the bottom to let water flow underneath. All collected oil is pumped into a storage tank built into the wall. Laboratory studies have shown that the coefficient of collected oil is 100 per cent at the low velocity of 0.14 m/s. It decreased to approximately 85 per cent for a high velocity of 0.28 m/s. This major drop in collection efficiency is expected once the critical Froude number is exceeded. 5 refs., 2 tabs., 12 figs
