Abstract

A hybrid riser system (10) for connection between a floating unit (12) and a sub-sea unit (14) that is located at the sea floor (18). The riser system (10) comprises a composite conduit (22) for transporting a fluid between said floating (12) and sub-sea units (14) and at least one end pipe section (20,24) that is adapted to be connected between the floating (12) and/or the subsea unit (14) and the composite conduit (22). Said at least one end pipe section (20,24) comprises a metallic pipe or a non-bonded flexible pipe.

Claims

AMENDED CLAIMS[received by the International Bureau on 13 June 2006 (13.06.06); original claims 1-11 replaced by new claims 1-16]CLAIMS
1. A hybrid riser system (10) for connection between a floating unit (12) and a sub-sea unit (14) that is located at the sea floor (18), characterized in that it comprises a composite conduit (22) for transporting a fluid between said floating (12) and sub-sea units (14) and at least one end pipe section (20,24) that is adapted to be connected between the floating (12) and/or the sub-sea unit (14) and the composite conduit (22), whereby said at least one end pipe section (20,24) comprises a metallic pipe or a non-bonded flexible pipe.
2. A riser system according to claim 1, characterized in that said at least one end pipe section (20,24) is arranged to be negatively buoyant.
3. A riser system according to claim 1 or 2 , characterized in that the composite conduit (22) is constituted by a single, continuous composite conduit.
4. A riser system according to any of claims 1-3, characterized in that it has a light and almost buoyant composite conduit section (22) so as to assume a neutral or slightly negative buoyancy.
5. A riser system according to any of claims 1-4, characterized in that it is adapted to assume a compliant configuration when installed.
6. A riser system according to claim 5, characterized in that said compliant configuration is a free hanging (catenary) configuration.
7. A riser system according to claim 5, characterized in that said compliant configuration is a Lazy S or Lazy wave configuration .
8. A riser system according to claim 5, characterized in that said compliant configuration is a Steep S or Steep wave configuration.
9. A riser system according to any of the preceding claims, characterized in that the composite conduit (22) comprises a bonded pipe having an inner liner (30) and an outer protective sheath, and optionally at least one reinforcing layer (32) .
10. A riser system according to any of the preceding claims, characterized in that the upper and/or lower ends of the composite conduit section (22) are terminated in a composite-metallic interface connector (26) .
11. A riser system according to any of the preceding claims, characterized in that the composite conduit (22) is flexible enough to be spooled onto a reel with a hub radius of about 4500-8500 mm.
12. A riser system according to any of the preceding claims, characterized in that the composite conduit (22) and said at least one end pipe section (20,24) have an internal diameter in the range of about 10-40 cm.
13. A riser system according to any of the preceding claims, characterized in that the length of the end pipe section (20) that is connected to the floating unit (12) is approximately 50-600 m.
14. A riser system according to any of the preceding claims, characterized in that the length of the end pipe section (24) that is connected to the sub-sea unit is approximately 50-100 m.
15. A riser system according to any of the preceding claims, characterized in that the length of the composite conduit (22) is about 1000-1500 m or longer.
16. A riser system according to any of the preceding claims, characterized in that the floating unit (12) is a production or storage unit or a platform or vessel, and the sub- sea unit (14) is a sub-sea well facility, wherein the riser system (10) is adapted for transport of fluids, in particular hydrocarbons, such as oil and/or gas, or injection fluids, such as methanol or water, between the floating (12) and sub-sea (14) units.
