The KOSEQ Rigid Sweeping Arms are available to CGA members through the contract with T&T Marine, Inc. There are 11 sets of KOSEQ Rigid Sweeping Arms prepositioned in Harvey, LA and Galveston, TX.
The KOSEQ Rigid Sweeping Arms is a skimming system available to CGA members through a contract with T&T Marine, Inc. Each system requires a large Offshore or Platform Supply Vessel (OSV/PSV), greater than 200’ with at least 100’ x 50’ of free deck space for deployment. A 50 foot long rigid framed Arm is deployed on each side of the vessel that consists of pontoon chambers to provide buoyancy, a smooth nylon face, and a hydraulically adjustable mounted weir skimmer. The Arm floats independently of the vessel and is attached by a tow bridle and a lead line. The movement of the vessel forward draws the rubber end seal of the arm against the hull to create a collection point for free oil directed to the weir by the Arm face.
The weir is hydraulically adjusted to maximize oil recovery and minimize excess water collection. A positive displacement screw type and centrifugal transfer pump suited for highly viscous oils then pumps the recovered liquid to portable tanks and/or dedicated fixed storage tanks onboard the vessel. Once separated, and with approval from the Coast Guard, the water can be pumped off from the bottom of the portable tanks, in front of the collection arm, to be reprocessed through the system. Once full with as much pure recovered oil as possible, the oil is transferred to a temporary storage barge for disposal in accordance with an approved disposal plan.
