Filed:

Sep 21, 2004

Appl. No.:

10/711489

Inventors:

John Christian Hartley Mungall - Houston TX, US
Khamir Girish Joshi - Sugar Land TX, US
Craig Wonder Lamison - Houston TX, US

Assignee:

Kellogg Brown & Root, Inc. - Houston TX

International Classification:

F16L 1/12

US Classification:

405158, 405162, 405171, 4051844

Abstract:

Various apparatuses and methods to traverse an undersea topographic feature () with a subsea pipeline () are disclosed. The apparatuses and methods of the present invention accomplish this task through the use of a concentrated buoyancy scheme (). The invention disclosed can allow more efficient and cost effective traversal of hostile terrain for subsea pipelines at great depths while minimizing the risk of rupturing the pipeline () or negatively impacting the surrounding undersea environment.

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 29/12

US Classification:

166355, 166358, 166368, 405224

Abstract:

An offshore riserless drilling system drills a subsea borehole from a platform and through a cased borehole. The system comprises a lightweight drill string suspending a bottomhole assembly and extending from the platform downwardly through a depth of water into the cased borehole; a first limiter limiting the range of motion of the drill string adjacent the platform; and a second limiter limiting the range of motion of the drill string adjacent the cased borehole. The preferred methods include lowering a bottomhole assembly suspended on a lightweight drill string from a platform through a depth of water; limiting the bend radius of the drill string adjacent the platform; guiding the bottomhole assembly into a cased borehole; limiting the bend radius of the drill string adjacent the cased borehole; maintaining the bottomhole assembly in the cased borehole, and drilling the subsea borehole.

International Classification:

E21B 29/12

US Classification:

166355, 166350, 166367, 4052244

Abstract:

Disclosed are compliant variable tension risers () to connect deep-water subsea wellheads () to a single floating platform (). The variable tension risers () allow several subsea well-heads (), in water depths from 4,000 to 10,000 feet, at lateral offsets from one-tenth to one-half of the depth, to tie back to a single floating dry tree semi-submersible platform (). Also disclosed are methods to counter buoyancy and install variable tension risers using a weighted chain ballast line ().

US Classification:

166355, 166350, 166367, 4052244

Abstract:

Disclosed are compliant variable tension risers () to connect deep-water subsea wellheads () to a single floating platform () in wet tree or dry try systems. The variable tension risers () allow several subsea wellheads (), in water depths from 1220 to 3050 meters, at lateral offsets from one-tenth to twice the depth or more, to tie back to a single floating platform (). Also disclosed are methods to counter buoyancy and install variable tension risers using a weighted chain ballast line ().

Abstract:

Disclosed are methods to counter buoyancy and install variable tension risers using a weighted chain ballast line. An example of an apparatus used in conjunction with the embodiments includes compliant variable tension risers to connect deep-water subsea wellheads to a single floating platform. The variable tension risers allow several subsea wellheads, in water depths from 4,000 to 10,000 feet, at lateral offsets from one-tenth to one-half of the depth, to tie back to a single floating dry tree semi-submersible platform.
