Subsea well intervention system and methods

摘要

A system for performing an intervention on a subsea wellhead, the system including a production tree having a central axis, a first end, a second end, and a first flow bore extending axially from the first end to the second end. The production tree includes a master valve disposed along the first flow bore, a swab valve disposed along the first flow bore between the master valve and the first end, and a shearing device disposed along the first flow bore between the master valve and the second end. The second end of the production tree comprises a connector configured to releasably couple to the subsea wellhead, and the shearing device is configured to shear a component extending through the first flow bore.

1. A system for performing an intervention on a subsea well, the system comprising:
a production tree having a central axis, a first end, a second end, a first flow bore extending axially from the first end to the second end, and a second flow bore extending radially from the first flow bore; wherein the production tree includes a master valve disposed along the first flow bore, and a swab valve disposed along the first flow bore between the master valve and the first end; and an adapter module having a first end releasably coupled to the second end of the production tree, a second end configured to releasably coupled to the subsea well, a through bore extending from the first end of the adapter module to the second end of the adapter module, and a shearing device disposed along the through bore of the adapter module, wherein the shearing device is configured to shear a component extending through the through bore.
