Field Evaluation of the Super Seahawk and Marco Class V Oil Skimmers

📖 The Scoop

"Two oil spill recovery devices, the Super Seahawk and the Marco Class V, were evaluated at Esquimalt Harbour near Victoria, British Columbia in August 1977. The former is manufactured by Bennett Pollution Controls Limited, North Vancouver, B.C. and the latter by Marine Construction and Design Company, Seattle, Washington. The two devices were evaluated on the basis of the parameters: Oil Recovery Rate (ORR), the rate at which the device recovers oil; Oil Recovery Factor (ORF), the volume of oil recovered by the device versus the volume presented to it; Oil Content Factor (OCF), the percentage of oil in the liquid recovered by the device; and Emulsification Factor (EF), the percentage of water in the oil which was recovered by the device. These parameters were measured during trials in which three types of fresh oil (Alberta Crude, Diesel and Bunker C) were spilled in limited quantities (less than one barrel) directly in front of the skimmers. The trials took place under environmental conditions ranging from clear skies and calm seas to rain and slight chop"--Abstract.
