| Number | Title | Issue Date |
| 5997374 | Vessel securing system A system is provided for securing a vessel (24) such as a tanker to a moored body (12) that is moored to the sea floor, which enables the vessel to remain secured in more severe weather. In addition to the deployed length (27) of securing line (26) that e... | 12/07/1999 |
| 5957076 | Offshore turret upper bearing An offshore system is described, of the type that includes a turret (20) anchored to the sea floor and connected by at least an upper bearing assembly (34) to the vessel hull (14) so the hull can weathervane about the turret, wherein the upper bearing ass... | 09/28/1999 |
| 5797413 | Offshore fluid swivel spare A fluid swivel arrangement comprising a vertical stack of fluid swivels mounted on a turret of a weathervaning ship, enables a spare fluid swivel to be provided without requiring an additional pipe and consequent larger diameter of fluid swivels. A pair o... | 08/25/1998 |
| 5794700 | CAM fluid transfer system An offshore fluid transfer system (10) is provided, of the type that includes a riser (32) having an upper end (34) connected through a universal joint (36) to a turret (22) on a vessel and having a lower end (36) anchored by catenary chains (40), and tha... | 08/18/1998 |
| 5782197 | Offshore turret lower bearing A bearing assembly that mounts the lower portion of a rotatable large (at least 4 meters diameter) turret in a moonpool near the center of a vessel, avoids damage resulting from turret and/or vessel deformation in heavy seas, while facilitating initial al... | 07/21/1998 |
| 5575592 | TLP tension adjust system A tension leg platform system includes a relatively small platform (12, FIG. 3 ) and relatively low capacity tendons (16), despite providing sufficient tension to risers (34) that carry hydrocarbons from seafloor wells to the platform. With the platform f... | 11/19/1996 |
| 5542783 | TLP and detachable derrick vessel An offshore production system of the type that includes a TLP (tension leg platform) (12) and a derrick vessel (14) which moves to the TLP platform (16) whenever the derrick is required. The vessel carries fastener assemblies (131) that rigidly fix the ve... | 08/06/1996 |
| 5517937 | Offshore turret system A turret that is rotatably mounted on a vessel and connected to risers extending down to sea floor wells, is constructed so the turret is of moderate diameter to enable the use of a moderate size bearing and moderate weight turret, while providing room ar... | 05/21/1996 |
| 5515804 | Bearing support for single point terminal An arrangement is described for mounting a turret (18, FIG. 3) on the outer ends of beams, or mounts, whose inner ends are supported by a vessel hull (14) that can weathervane about the turret. An upper bearing (42) is supported on a largely rigid upper m... | 05/14/1996 |
| 5480264 | Offshore pipeline system An offshore fluid transfer system is described, for transferring fluid between stations (12, 14, FIG. 1) that may be many kilometers apart and lie in deep water, which avoids the need for making fluid connections at great underwater depths. A buoy station... | 01/02/1996 |
| 5477924 | Offshore well gas disposal A system is provided for disposal of gaseous hydrocarbons produced from an undersea well, which minimizes the gas disposal cost. The system includes a polymerization station (80) mounted on an anchored floating vessel arrangement (12), which converts the ... | 12/26/1995 |
| 5476059 | Turret drive mechanism A torque enhancer (60, FIG. 1) is provided for an offshore system wherein a turret (18) is rotatably mounted about a vertical axis (22) on a vessel hull and the turret is anchored by catenary chain devices (24), to help minimize rotation of the turret whe... | 12/19/1995 |
| 5411298 | High pressure seal arrangement A fluid swivel is described, of the type that carries oil, water or natural gas at high pressure between an undersea well and a weathervaning ship, which has a seal device of increased lifetime. The seal device (56, FIG. 2 ) lies in a cavity of a first sw... | 05/02/1995 |
| 5381750 | Vessel turret mooring system A vessel with a rotatable turret thereon is moored in a manner that minimizes turret tilt while avoiding the need to maintain precisely concentric upper and lower turret bearings. A mooring structure (152, FIG. 7) is formed by a group of mooring lines (16... | 01/17/1995 |
| 5312140 | Fluid swivel structure A fluid swivel is described, of the type which includes a ring-shaped outer structure (12, FIG. 2 ) that rotates about a ring-shaped inner structure (14), and which form an annular chamber (18) between them and a pair of gap passages (24, 26) between them... | 05/17/1994 |
| 5242198 | Fluid swivel seal arrangement A fluid swivel, of the type that carries oil, natural gas, or other fluid between an undersea well or pipeline and a weathervaning ship, wherein the seal arrangement that prevents leakage of fluid is constructed to increase the seal lifetime and reduce th... | 09/07/1993 |
| 5205768 | Multiple fluid swivel arrangement A multiple fluid swivel arrangement is described, for connecting stationary undersea pipes to rotatable pipes on a weathervaning ship, which provides ready access to each of the fluid swivels and which minimizes the diameters of the fluid swivels and thei... | 04/27/1993 |
| 5197826 | Offshore gas flare system Apparatus is described for flaring large amounts of natural gas at a location spaced from an offshore production platform. The apparatus includes a spar buoy structure (32, FIG. 1) anchored at a location on the order of 0.1 kilometer from the platform (12... | 03/30/1993 |
