Abstract |
Field studies of earthmoving equipment units were conducted to evaluate their use and effectiveness in restoring oil contaminated beaches. Specifically, operating procedures and cost estimates were desired, along with any useful design modifications. Previous beach restoration operations were reviewed prior to initiation of the field tests for information about the type of performance required. The field tests were then performed on each equipment/procedure unit to determine efficiency, flexibility, and performance characteristics under a variety of field conditions. Oil removal effectiveness was greater than 98% for all restoration procedures, with the highest effectiveness being achieved by a motorized grader and a motorized elevating scraper working in combination. Conveyor screening systems can be effectively utilized. Costs for removal are reported. (Author) |
