Title: Michael R Fitzgibbons: Innovator in Subsea Technology

Introduction

Michael R Fitzgibbons is a notable inventor based in Houston, TX (US), recognized for his contributions to subsea technology. He holds a total of 6 patents, showcasing his innovative spirit and technical expertise in the field.

Latest Patents

Among his latest inventions is the "Radial Seal Hydraulic Coupler." This improved hydraulic coupler is designed for interconnecting subsea fluid lines and features a radial seal between the male and female body portions. A C-shaped metallic seal is housed between the female body of the coupler and a retainer external to the female body. An elastomeric secondary seal is also provided on the retainer, which engages the same diameter cylindrical surface of the male coupler that is engaged by the C-shaped seal. Additionally, a wiper member mounted on the retainer cleans this cylindrical surface as the body portions are brought together, enhancing the reliability of both seals. The coupler halves can typically be housed within either a latchable subsea control module mounting base or a junction plate used in surface petroleum recovery operations.

Another significant patent is the "Method and Apparatus for Remote Control of an Underwater Valve." This invention provides improved techniques for opening or closing an underwater valve in a subsea fluid pipeline using an acoustic signal transmitted from the surface to a receiver adjacent the valve. A predetermined torquing force is applied to a shaft directly coupled to the valve stem, while rotation of the valve stem is prevented by the mechanical connection of an explosive bolt. Upon receipt of the transmitted acoustic signal, stored electrical energy is released, detonating the explosive bolt and breaking the mechanical connection. This process allows the pre-existing torquing force to rotate the valve stem, significantly increasing valve operation reliability.
