  • Publication number: 20080056825
    Abstract: Apparatuses including a subsea pipeline (18) extending from a first location (14) to a second location (16) and including at least one distributed buoyancy region (102) to traverse a seabed topographic feature (12) are presented. Methods including laying a subsea pipeline (218) including laying a negatively buoyant section of pipeline (218A), a distributed buoyancy section (202) of pipeline (218), and a second negatively buoyant section of pipeline (218B) from a pipelay vessel (220) to traverse an undersea topographic feature (212) are also presented.

  • Publication number: 20060210361
    Abstract: A pipeline segment 5, used for the manufacture of a thin-walled underwater pipeline 50, is disclosed. Terminal pipe sections 20 are at either end of main pipe section 10. Terminal pipe sections 20 are thick-walled or otherwise resistant to collapse due to external pressure. A pressure isolation device 30 maintains an internal pressure in main pipe section 10 above a shutoff pressure. A pressure compensation system 35 can protect main pipe section 10 from collapse due to external pressure. Pipeline segments 5 can be manufactured by connecting and winding stalks 100 onto storage device 110 forming main pipe section 10. Terminal pipe section 20 can be connected to the lead end of main pipe section 10, and main pipe section 10 can be unwound from storage device 110 while towing.

  • Publication number: 20060062635
    Abstract: Various apparatuses and methods to traverse an undersea topographic feature (12) with a subsea pipeline (18) are disclosed. The apparatuses and methods of the present invention accomplish this task through the use of a concentrated buoyancy scheme (10). The invention disclosed can allow more efficient and cost effective traversal of hostile terrain for subsea pipelines at great depths while minimizing the risk of rupturing the pipeline (18) or negatively impacting the surrounding undersea environment.
