Patent number: 10196879Abstract: An offshore well system for a subsea well, including a floating platform, a drilling riser system connected with the well for drilling operations, and a production riser system connected with the well for production operations. The drilling system also includes a riser tension system. The riser tension system is capable of compensating for movement of the platform while adequately tensioning both drilling riser system and the production riser system when each is connected to the well.Type: GrantFiled: July 24, 2015Date of Patent: February 5, 2019Assignee: Cameron International CorporationInventors: David Cain, William F. Puccio, Shian J. Chou

Patent number: 10151167Abstract: An offshore well system for a subsea well. The system includes a floating platform, an external riser and an internal riser nested within the external riser. A external riser tension device tensions the external riser. The drilling system also includes a surface wellhead system that includes a wellhead, a collet, and a flange assembly. The wellhead, collet, and flange assembly are assembled to establish a common bore for receiving the top of the internal riser. A gasket located between the top of the internal riser and an inner shoulder of the flange assembly seals between the wellhead system and the top of the internal riser. The surface wellhead system also retains the internal riser in tension with the wellhead, the internal riser extending above the wellhead into the collet.Type: GrantFiled: July 18, 2016Date of Patent: December 11, 2018Assignee: Cameron International CorporationInventors: David Cain, William F. Puccio, Shian J. Chou, Vijay A. Cheruvu, Kirk P. Guidry, Clint Trimble

Patent number: 9574426Abstract: An offshore well drilling system for drilling a subsea well is presented that includes a floating platform, a surface BOP stack, a riser, and a driveable environmental safe guard system. The safe guard system includes an upper wellhead connector, a lower wellhead connector, a blowout preventer with shearing blind rams, and a subsea pressure control system. The subsea pressure control system can be electric, hydraulic, acoustic, or ROV actuated. More importantly, the environmental safeguard system is moveable, and can be driven around using as ROV. The present invention provides swift disconnect and recovery for emergency situations. The subsea environmental safe guard system is also much lighter in weight than traditional subsea stacks.Type: GrantFiled: September 30, 2015Date of Patent: February 21, 2017Assignee: Cameron International CorporationInventors: David E. Cain, Shian J. Chou, Vijay A. Cheruvu, William F. Puccio

Publication number: 20150337514Abstract: An offshore system with a subsea riser, including a floating platform and a subsea riser made up of sections of pipe. A riser tension system compensates for movement of the platform while providing tension to the riser. At least two of the riser sections are connected with a connector such that a portion of the riser is able to be placed in compression without buckling.Type: ApplicationFiled: July 30, 2015Publication date: November 26, 2015Inventors: David Cain, William F.
