Title: Innovations of William Matthew Caldwell
Introduction
William Matthew Caldwell is a notable inventor based in Ocean Springs, MS (US). He has made significant contributions to the field of marine drilling technology, holding a total of 5 patents. His work focuses on enhancing the safety and efficiency of underwater operations.
Latest Patents
Caldwell's latest patents include a riser disconnect package for lower marine riser packages and annular-release flex-joint assemblies. This innovative riser disconnect/reconnect system features a disconnection package (RDP) and a modified lower marine riser package (LMRP) designed for quick disconnection of the marine drilling riser (MDR) from the LMRP. This system facilitates access to the LMRP or blowout preventer (BOP) stack. The RDP incorporates a flex joint and a hydraulically-actuated release connector (RC) that engages a modified LMRP. In emergency situations, the RDP can be disconnected from the LMRP, allowing for intervention at the BOP stack. Additionally, the RDP can be used to recover the LMRP or BOP stack to the surface for maintenance without the need to recover the MDR. The RC connects the flex joint to the uppermost annular blowout preventer in the LMRP and can be utilized in both standard and inverted positions. Structural cages with complementary stab plates are also provided, allowing access to various bypass ports and controls.
Another significant patent involves an apparatus and method for isolating and securing an underwater oil wellhead and blowout preventer. This drilling package is designed for offshore wellbores and includes a shear module, a blowout preventer, and a lower marine riser package, all in fluid communication with one another. A bypass valve and port are included in the normal fluid path upstream of a well closure device, which is actuated to divert flow from the normal path through the blowout preventer to an alternative flow path.
