US Patent:

20130220436, Aug 29, 2013
Filed:

Feb 29, 2012
Appl. No.:

13/408055
Inventors:

Jarred Christopher Sharp - Houston TX, US
Scott Oren Crook - Carriere MS, US
Jimmie Dean Adkins - San Ramon CA, US
Daniel Christopher Kefford - Houston TX, US
Edward Shintaro Nakajima - Sugar Land TX, US
Jean Michael Thibodeaux - Covington LA, US
Assignee:

Chevron U.S.A. Inc. - San Ramon CA
International Classification:

B23P 17/00
US Classification:

137 1501
Abstract:

Disclosed is an apparatus for sealing and severing a subsea pipe adapted to convey fluids, e.g., hydrocarbons, and systems and methods using such apparatus. The apparatus includes a housing adapted to attach to the pipe, a piercing tool for providing an opening in the pipe at a predetermined location and a mechanism for establishing fluid communication between a source of sealant material and space within the pipe adjacent the opening in the pipe, and a cutting mechanism for cutting the pipe. Methods disclosed include piercing the pipe to form an opening, injecting sealant material through the opening into the pipe to form a fluid-tight seal, and cutting the pipe through the seal to form sealed cut ends.

US Patent:

20130216314, Aug 22, 2013
Filed:

Feb 20, 2012
Appl. No.:

13/400480
Inventors:

Antonio Carlos Falcao Critsinelis - Kingwood TX, US
Sid Ahmed Mebarkia - Sugar Land TX, US
Edward Shintaro Nakajima - Sugar Land TX, US
Assignee:

Chevron U.S.A. Inc. - San Ramon CA
International Classification:

F16L 1/12
B63B 35/03
US Classification:

4051683
Abstract:

Disclosed are systems and methods for reel laying of subsea pipe in such a way that mitigates buckling and axial displacement of the pipe in use for conveying produced hydrocarbon fluids. The systems and methods include adjusting the settings of the pipe straightener and/or the pipe aligner during the reel laying process to provide non-straightened sections of pipe at predetermined locations along the length of the pipe. The non-straightened sections allow for thermal expansion of the pipe during use.

Filed:

Mar 15, 2013
Appl. No.:

13/836363
Inventors:

Antonio Carlos Falcao Critsinelis - Kingwood TX, US
Hugh Miller Thompson - Houston TX, US
Sid Ahmed Mebarkia - Sugar Land TX, US
Edward Shintaro Nakajima - Sugar Land TX, US
Estela Gonzalez - Houston TX, US
Assignee:

Chevron U.S.A. Inc. - San Ramon CA
International Classification:

F16L 57/00
US Classification:

405171
Abstract:

Disclosed are systems and methods for protecting subsea pipeline from damage caused by excessive stress or fatigue loading caused by geo-hazards, and environmental and operating loads. The systems and methods utilize lifting buoyancy modules capable of being attached to a section of subsea pipeline to lift the subsea pipeline off the seabed to a predetermined height over a predetermined length upon being activated by a planned or unplanned triggering event.
