Stiff Sweep Arm

Stiff Sweep Arm

The Lamor Stiff Sweeping Arm can be incorporated with both the proven stiff brush oil recovery technology and optionally also weir skimmer as exchangeable modules. The design offers high performance and safety for offshore oil spill recovery operations. The 6 Chain LAMOR Brush Conveyor Belt is a removable recovery system for oil spills on the water surface. It is used in nearly 1,000 delivered Lamor advancing skimming systems (like the built-in recovery systems, Side Collector systems, Catamaran recovery systems, and Bow Collectors).

“Ideal for a firm sweep, in light to moderate seas, for fast recovery of spill oil off the surface”

How it works

The forward motion of the vessel deflects surface water and oil from the collection area formed by the sweeping arm into the recovery process in the apex formed by the sweeping arm and vessel hull. The flow leads the oil to the collection module which is equipped either by LAMOR brush pack skimmer or a weir type skimmer and the oil transfer pump. The superior advantage of the brush assisted stiff sweep system is that the brush conveyor separates the oil from the flow and compared to the traditional weir type stiff sweep arrangement, which typically collects more than 50 % water, the free water content with the brush conveyor can be limited to less than 10 %. The conveyor belt is mounted in the apex of the Lamor Stiff Sweep arm LSS. With the LAMOR Stiff sweep arm deployed, the entire vessel becomes an "oil slick processing system".
