Abstract

A system and method for mating risers or umbilicals (14) extending vertically or near vertically from the ocean floor to a floating offshore system (10). The risers or umbilicals (14) are suspended vertically above the vessel's keel and are supported laterally near the platform's keel by keel guides or riser receptacles (7).

Claims

AMENDED CLAIMS received by the International Bureau on 29 April 2005 (29 04 05) original claims 1-43 have been replaced by amended claims 1-43 (1-43)
1. A method for coupling a plurality of risers or umbilicals having lower ends fixed to an area of the sea floor to a floating vessel having a hull with a keel and moored generally above said area, the method comprising the steps of, enduringly suspending said risers or umbilicals from an elevation above said hull, and laterally supporting said risers or umbilicals at points along the perimeter of said hull.
2. The method of claim 1 further comprising the step of, laterally supporting said risers or umbilicals below the waterline.
3. The method of claim 1 further comprising the step of, laterally supporting said risers or umbilicals at an elevation generally corresponding to the elevation of said keel.
4. The method of claim 1 further comprising the step of, laterally supporting said risers or umbilicals at outboard-facing surfaces of said hull.
5. The method of claim 1 further comprising the step of, laterally supporting said risers or umbilicals at inboard-facing surfaces of said hull.
6. The method of claim 1 further comprising the step of, laterally supporting said risers or umbilicals at surfaces of a moonpool in said vessel.
7. The method of claim 1 further comprising the steps of, providing a bearing at each of said points, and allowing axial movement of said riser relative to said vessel.
8. The method of claim 1 wherein said step of laterally supporting said risers or umbilicals further comprises the step of, providing a plurality of keel guides disposed at said points.
9. The method of claim 8 further comprising the step of, allowing side entry of one of said risers or umbilicals into at least one of said keel guides.
10. The method of claim 8 further comprising the step of, allowing vertical entry of one of said risers or umbilicals into at least one of said keel guides.
11. The method of claim 1 wherein said suspending further comprises the steps of, tensioning said risers or umbilicals, and allowing said risers or umbilicals to move axially with respect to said vessel.
12. The method of claim 1 further comprising the step of, suspending said risers or umbilicals with a generally vertical orientation.
13. The method of claim 1 further comprising the step of, suspending said risers or umbilicals from an elevation above the waterline.
14. The method of claim 1 further comprising the step of, suspending said risers or umbilicals by a spring.
15. (Cancelled)
16. A method for coupling a plurality of risers or umbilicals having lower ends fixed to an area of the sea floor to a floating vessel having a submerged hull with a keel and moored generally above said area, the method comprising the steps of, enduringly suspending said risers or umbilicals from an elevation above said keel, and laterally supporting said risers or umbilicals in vertical passages formed through said hull.
17. The method of claim 16 further comprising the steps of, providing a bearing in each of said passages, and allowing axial movement of said riser relative lo said vessel.
18. The method of claim 16 wherein said suspending further comprises the steps of, tensioning said risers or umbilicals, and allowing said risers or umbilicals to move axially with respect to said vessel,
19. The method of claim 16 further comprising the step of, suspending said risers or umbilicals with a generally vertical orientation.
20. The method of claim 16 further comprising the step of, suspending said risers or umbilicals from an elevation above the waterline.
21. The method of claim 16 further comprising the step of, suspending said risers or umbilicals by a spring.
22. (Cancelled)
23.

31. The vessel of claim 23 wherein, said keel guide is disposed at an elevation generally corresponding to the elevation of said keel.
32. The vessel of claim 23 wherein, said keel guide is disposed at an elevation generally corresponding to the elevation of said upper end of said mooring device.
33. (Cancelled)
34. The vessel of claim 23 wherein, said tensioner is disposed above the waterline.
35. The vessel of claim 23 wherein, said tensioner is disposed on said deck.
36. A floating vessel comprising, a submerged buoyant hull having a keel, a column having a lower end coupled to said hull, said column extending above the waterline, a deck coupled to an upper end of said column, a mooring device having an upper end coupled to said hull and a lower end coupled to the seabed, an aperture vertically formed through said hull, a tensioner coupled to said vessel and disposed at an elevation above said hull, and a riser or umbilical having a lower end coupled to the seabed and an upper end enduringly coupled to said tensioner, said riser or umbilical passing within said passage of said keel guide.
