US Patent:

6579040, Jun 17, 2003

Filed:

Jul 26, 2001

Appl. No.:

09/917564

Inventors:

Metin Karayaka - Houston TX

Assignee:

CSO Aker Maritime, Inc. - Houston TX

International Classification:

F16L 112

US Classification:

4052242, 405162, 405171, 405211, 4052244, 166350, 166367, 175 8

Abstract:

An air-can riser tensioning device for use in the production of oil and gas at offshore locations includes at least one air-can used to place a vertical force on the riser. The air-can includes an open port that extends into the water toward the sea floor to a depth sufficient to prevent water from entering or air from leaving the air-can during its upward and downward vertical movements while in use. A manufacturing method includes fabricating the air-cans out of one material and fabricating the open port out of another material, and in particular making the open port from a material that is more corrosion resistant than the material the air-can is fabricated from. The manufacturing method further includes fabricating a passage in one soft tank for fluid communication with a second soft tank, and connecting the second soft tank with the passage.

International Classification:

E21B 1701

US Classification:

441133, 166367, 4052242

Abstract:

A buoyancy system for deep-water risers of a deep water floating platforms includes an ecto-skeleton formed by a plurality of members to withstand lateral and bending loads, and a buoyant vessel disposed in an interior cavity of the ecto-skeleton to resist pressure loads. The member of the ecto-skeleton can include hollow tubular members having hollow interiors with a buoyant material disposed in the hollow interiors of the tubular members.

Abstract:

There is provided a buoyancy system for a structure having at least one component being substantially stationary with respect to the bottom of a water covered area. The system comprises a set of buoyancy modules of engineered materials to apply an identified amount of buoyancy. The set of buoyancy modules is attached to the structure at a set of buoyancy load transfer locations. The set of buoyancy modules comprises layers of the engineered materials. The engineered materials comprise a substantially reinforced axial layer, a substantially reinforced hoop layer; and a leak prevention layer.

Appl. No.:

10/719780

Inventors:

James Elvin Dailey - Spring TX, US
Metin Karayaka - Houston TX, US

Assignee:

Technip France - Courbevoie

International Classification:

E21B 29/12

US Classification:

166359, 166367, 4052242

Abstract:

A buoyancy can for supporting an offshore oil and gas riser includes an axial bore through which the riser extends coaxially, and a radio-axial slot extending through a side of the can and into the axial bore. A pair of spaced-apart support features are disposed coaxially on the riser, and the can includes a pair of corresponding sockets in the axial bore thereof. The sockets are adapted to receive and vertically support respective ones of the support features in a complementary, axial engagement. The can is placed in the water and moved laterally relative to a fully assembled, vertically supported riser such that the riser passes through the radio-axial slot of the can and into the axial bore thereof without the need for disassembly of the upper portion of the riser. The relative vertical positions of the can and riser are then adjusted such that the support features engage and seat within respective ones of their complementary sockets.

International Classification:

E21B 17/01

US Classification:

166367, 166350, 166359, 114264, 4052244

Abstract:

A floating offshore platform, of the type having a buoyancy can disposed within a support structure, includes a can guide assembly that has at least two compliant compression pads that are configured and arranged to provide a non-linear load-versus-deflection characteristic in response to impact loads generated by the impact of the can against the guide assembly. At least one of the compression pads is substantially stiffer (less compliant) than the other pad. The pads are arranged so that the relatively soft pad absorbs the impact load before the relatively stiff pad is engaged. In one embodiment, first, second, and third compression pads are arranged vertically, the upper and lower pads being softer (more compliant) than the middle pad. In another embodiment, a first, relatively soft, compression pad coaxially surrounds a second, relatively stiff compression pad.
