Latest Patents

One of his latest patents is a swivel assembly designed for installation at a well for subsea production of oil or gas. This swivel assembly is adapted to connect to a production vessel at the sea surface. It features a main fluid swivel with at least two paths and an electric/hydraulic auxiliary swivel for signal communication and power transfer. The fluid swivel includes a rotatable swivel housing positioned atop a stationary Christmas tree, which typically comprises a limited number of valves, such as a production master valve and an annulus master valve. The paths run vertically through the central core member of the fluid swivel, allowing for well intervention from the upper side.

Another significant patent involves a system for offshore production of oil or gas. This system includes a surface vessel equipped to maintain a desired position and orientation, along with a bottom installation at the seabed for at least two production wells. The vessel is outfitted with drilling equipment for seabed wells and process equipment for handling produced oil or gas. The bottom installation features a template with a foundation at the seabed, a manifold unit, and at least two well head sections for installing associated Christmas trees. A drill string extends from the vessel's drilling equipment to an operation module at the bottom installation, while a product riser connects the operation module to the vessel's process equipment.
