  • Distributed buoyancy subsea pipeline apparatus and method
    Patent number: 7963721
    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.
    Type: Grant
    Filed: September 21, 2004
    Date of Patent: June 21, 2011
    Assignee: Kellogg Brown & Root LLC
    Inventors: Khamir Girish Joshi, John Christian Hartley Mungall, Craig Wonder Lamison

  • Concentrated buoyancy subsea pipeline apparatus and method
    Patent number: 7025533
    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.
