РЕФЕРАТ (Abstract)

The method of protecting two subsea pipelines which cross each other in a subsea environment from damaging one another when subsea currents slide the upper pipeline along the upper surface of the lower pipeline by providing roller around the upper pipeline and rollers around the lower pipeline which are connected together by a rotatable connection which allows the sets of roller to match the angle of the pipeline.

ФОРМУЛА ИЗОБРЕТЕНИЯ (CLAIMS)

That which is claimed is:

1. The method of protecting an upper subsea pipeline and a lower subsea pipeline which cross one another from damaging one another, comprising: providing a upper clamp section around said upper subsea pipeline which is able to move along said upper subsea pipeline without damaging said upper subsea pipeline, providing a lower clamp section around said lower subsea pipeline which is able to move along said lower subsea pipeline without damaging said lower subsea pipeline, providing a rotatable connection between said upper pipeline section and said lower subsea pipeline section.

2. The method of claim 1 further comprising unitizing said upper clamp section, said lower clamp section, and said rotatable connection into a pipeline tee.

3. The method of claim 2 further comprising said pipeline tee is lowered to engage said upper subsea pipeline in an upside down orientation relative to the anticipated installed orientation.

4. The method of claim 3 further comprising after said pipeline tee engages said upper subsea pipeline, said pipeline tee is rotated to the anticipated installed orientation.

5. The method of claim 4 further comprising adjusting the angle of said lower clamp section to match the orientation of said lower subsea pipeline.

6. The method of claim 5 further comprising moving said pipeline tee along said upper subsea pipeline to a position above said lower subsea pipeline.

7. The method of claim 6 further comprising lowering said upper subsea pipeline and said pipeline tee to engage said lower clamp section of said pipeline tee with said lower subsea pipeline.

8. The method of claim 1 further comprising providing rollers to said clamp sections to provide the ability to move along said pipelines.

9. The method of claim 8, further comprising said rollers to be profiled to generally conform to the outer circumference of said pipeline.

10. The method of claim 1 further comprising said upper subsea pipeline is the same diameter as said lower subsea pipeline.

11. The method of claim 1 further comprising said upper subsea pipeline is larger than said lower subsea pipeline.

12. The method of claim 1 further comprising said upper subsea pipeline is smaller than said lower subsea pipeline.

13. The method of protecting an upper subsea pipeline and a lower subsea pipeline which cross one another from damaging one another, comprising: providing a upper clamp section around said upper subsea pipeline which is engaged by contacting said upper subsea pipeline and which is able to move along said upper subsea pipeline without damaging said upper subsea pipeline, providing a lower clamp section around said lower subsea pipeline which is engaged by lowering against said lower subsea pipeline and which is able to move along said lower subsea pipeline without damaging said lower subsea pipeline, providing a rotatable connection between said upper pipeline section and said lower subsea pipeline section.

14. The method of claim 13 further comprising unitizing said upper clamp section, said lower clamp section, and said rotatable connection into a pipeline tee.

15. The method of claim 14 further comprising said pipeline tee is lowered to engage said upper subsea pipeline in an upside down orientation relative to the anticipated installed orientation.

16. The method of claim 15 further comprising after said pipeline tee engages said upper subsea pipeline, said pipeline tee is rotated to the anticipated installed orientation.

17. The method of claim 16 further comprising adjusting the angle of said lower clamp section to match the orientation of said lower subsea pipeline.

18. The method of claim 17 further comprising moving said pipeline tee along said upper subsea pipeline to a position above said lower subsea pipeline.

19. The method of claim 17 further comprising lowering said upper subsea pipeline and said pipeline tee to engage said lower clamp section of said pipeline tee with said lower subsea pipeline.

20. The method of claim 13 further comprising providing rollers to said clamp sections to provide the ability to move along said pipelines.
