Scope of work

The US Army Corps of Engineers Physical Support Branch Dredge Goetz is requesting the purchase of one suction hose and 8 discharge hoses for the Dredge Goetz. The Dredge Goetz is a 20" cutter head dredge and the hose will be installed on the suction side of the main dredge pump between the rigid hull pipe and movable suction pipe on the dredge ladder. The deflection of this hose is approximately 5 degrees above the horizontal plane of the hull pipe to approximately 30 degrees below the horizontal plane of the hull pipe.

The discharge hoses are used in the floating slurry pipeline to allow flexibility between the steel pipes.
