Latest Patents

Henderson holds a patent for a "Packoff Running Tool with Rotational Cam." This innovative running tool is designed for setting a casing hanger packoff in a subsea well. The tool features a connection assembly that links it to the casing hanger, along with a mandrel that connects to a string of drill pipe. A setting sleeve is carried by the mandrel to accommodate the packoff. The tool's body includes a split ring that transitions between an extended position, engaging a groove in the casing hanger, and a retracted position. The movement of the split ring is controlled by an annular cam, which is threaded to the body and moves longitudinally when rotated. The mandrel extends through the cam and incorporates a longitudinal slot, allowing a dog to engage with it. A flexible link connects the dog to the cam, enabling the rotation of the mandrel to also rotate the cam. This design allows for efficient packoff setting in subsea environments.
