Latest Patents

Stokes holds a patent for a "High capacity wellhead connector having a single annular piston." This invention is designed to connect a riser or production tree to a wellhead of a subsea well. The wellhead connector utilizes a singular annular piston to securely lock the connector onto the wellhead. The design includes a housing that contains dogs for engagement with the exterior of the wellhead housing. A cam ring is incorporated, which engages the dogs and moves them inward into a locked position with the wellhead housing. The cam ring is proportionally reduced compared to prior art, allowing it to contact the inner side of the connector housing under load. Connecting rods link the piston to the cam rings, facilitating the locking and unlocking mechanism. A secondary annular piston is also included to ensure reliable unlocking.
