Latest Patents

Darren Mills' latest patents include:

1. **Systems and Methods for Riser Coupling**: This patent discloses a riser coupling system that comprises a riser joint connector with a first tubular assembly coupled to a second tubular assembly. A spider assembly receives the riser joint connector and includes a connector actuation tool, which features a dog assembly, a clamping tool, and a splined member. The dog assembly selectively extends to engage the riser joint connector, while the clamping tool couples the two tubular assemblies. Ultimately, the splined member actuates the locking member of the riser joint connector.

2. **Subsea Well Production System**: This invention involves a tubing hanger positioned within the bore of a wellhead body. The tubing hanger has a vertical bore from which a tubing string may be suspended within a well bore. Upon landing the hanger, a fluid passageway connected to a pressure-responsive downhole function is opened by a poppet valve that is urged closed but can allow fluid pressure to be supplied when needed.
