METHODS AND APPARATUS FOR ARRESTING FAILURES IN SUBMERGED PIPELINES |
| 摘要 |
A packer apparatus is configured to be arranged within and arrest a failure of a submerged pipeline. In one example, the packer apparatus includes first and second mandrels in axially moveable relation to one another, a brake connected to the second mandrel, and an elastomeric expansion boot circumferentially disposed around a portion of the first and second mandrels. The first mandrel is configured to move axially toward the second mandrel from a first position to a second position. In the second position, the first mandrel is configured to cause the expansion boot to be compressed axially between the first and second mandrels and expanded radially into engagement with an inner surface of the pipeline, and to cause the brake to move radially outward to engage the inner surface of the pipeline. |

1. A packer apparatus configured to be arranged within and arrest a failure of a submerged pipeline, the packer apparatus comprising:
first and second mandrels in axially moveable relation to one another; a brake connected to the second mandrel; and an elastomeric expansion boot circumferentially disposed around a portion of the first and second mandrels, wherein the first mandrel is configured to move axially toward the second mandrel from a first position to a second position, and wherein, in the second position, the first mandrel is configured to cause:
the expansion boot to be compressed axially between the first and second mandrels and expanded radially into engagement with an inner surface of the pipeline; andthe brake to move radially outward to engage the inner surface of the pipeline. |
