Abstract : The LORI LSC-2 side collector skimming unit was tested at the Ohmsett test facility in Leonardo, NJ, in May 1993. The system is comprised of an 8.5m (28 ft) workboat with one LORI LSO-2 unit mounted on each side, one with coarse brushes and one with fine brushes. A diversion boom system designed specifically for the LSC-2 side collectors was mounted on each side of the vessel. The objective of the testing was to evaluate the effectiveness of the LORI brush system at recovering floating oil. The skimming vessel was towed at five different forward velocities from 1.5 to 3.5 knots both in calm water and in waves. Three test oils were used; a light diesel fuel (5 cSt), a medium refined oil (600 cSt), and a heavy blend of refined oils (10,000 cSt). The fine-brush collector failed to collect a measurable quantity of light oil. The coarse-brush collector failed to collect measurable quantities of medium oil. The fine-brush collector collected a small amount of medium oil. The coarse-brush collector recovered heavy oil at recovery rates from 1.12 to 3.39 m3lhr (4.9 to 14.9 gpm).
