The CHIMERA Riser Cleaning Tool simultaneously brushes and collects debris that resides in the Riser. It is designed to pass through wellhead ID restrictions and is equipped with full coverage brushes to maximize cleaning efficiency. An integral junk basket ensures that debris removal is captured and retained.

To effectively clean around the BOP and wellhead, the CHIMERA BOP Jetting Sub is utilized. The BOP Jetting Sub includes replaceable nozzles and is activated by dropping a dart that lands on a shear sleeve exposing the nozzles when required. The shear loads can be adjusted by shear pin selection and the dart is retrievable to re-establish bore flow as required.
