Patent number: 7096958Abstract: 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.Type: GrantFiled: January 20, 2004Date of Patent: August 29, 2006Assignee: Technip FranceInventors: Metin Karayaka, John Montague

Patent number: 7059416Abstract: 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.Type: GrantFiled: November 21, 2003Date of Patent: June 13, 2006Assignee: Technip FranceInventors: James Elvin Dailey, Metin Karayaka

Patent number: 6579040Abstract: 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.Type: GrantFiled: July 26, 2001Date of Patent: June 17, 2003Assignee: CSO Aker Maritime, Inc.Inventor: Metin Karayaka

Patent number: 6488447Abstract: A buoyancy system for a deep water floating platform includes at least one composite buoyancy module coupled to the a riser having a length greater than 1000 feet and an associated weight. The composite buoyancy module is sized to have a volume to produce a buoyancy force at least as great as the weight of the riser. The composite buoyancy module may include a vessel with a composite vessel wall. The buoyancy module or vessel may have a non-circular cross-section defining an area which is greater than approximately 79 percent of an area defined by a square with sides tangent to the vessel wall to maximize buoyancy. A second buoyancy module may be directly coupled to the first buoyancy module to achieve a desired buoyancy.Type: GrantFiled: October 18, 2000Date of Patent: December 3, 2002Assignee: EDO CorporationInventors: Randall W.
