Publication number: 20120186820Abstract: A system and method to allow backup or alternate fluid flow routes around malfunctioning components using removable, modular component sets. In one exemplary embodiment, an ROV establishes a backup hydraulic flow to a BOP function by attaching one end of a hose to a modular valve block and the other end to an intervention shuttle valve, thus circumventing and isolating malfunctioning components. A compound intervention shuttle valve is provided that comprises first and second primary inlets, first and second secondary inlets, and an outlet. A modular valve block is provided that comprises a directional control valve, a pilot valve, a manifold pressure regulator, a pilot pressure regulator, stab type hydraulic connections and an electrical wet-make connection.Type: ApplicationFiled: March 30, 2012Publication date: July 26, 2012Applicant: Transocean Offshore Deepwater Drilling Inc.Inventors: Steve Donahue, Steve O'Leary, Tom Thrash, Angela Donohue

Patent number: 7975770Abstract: The disclosure is drawn to methods of drilling wells utilizing blow out prevention components of differing pressure ratings. In the initial drilling phase, a lower pressure rated blow out prevention component is used. In a subsequent drilling phase where a reservoir of a natural resource is penetrated, a higher pressure rated blow out prevention component is used.Type: GrantFiled: December 22, 2006Date of Patent: July 12, 2011Assignee: Transocean Offshore Deepwater Drilling Inc.Inventor: Chip Keener

Publication number: 20090095464Abstract: An apparatus to allow backup or alternate fluid flow routes around malfunctioning BOP control components using a remotely installed removable hydraulic hose connection. The backup fluid flow route sends pressure-regulated hydraulic fluid to a BOP operation via an isolation valve rigidly attached to the BOP, then to a hose connected to an intervention panel on the BOP and finally through a valve that isolates the primary flow route and establishes a secondary flow route to allow continued operation. To increase reliability, the backup components route from a spare BOP function and are rigidly fixed to the BOP.Type: ApplicationFiled: September 19, 2008Publication date: April 16, 2009Applicant: Transocean Offshore Deepwater Drilling Inc.Inventors: Scott P. McGrath, Brian K. Williams
