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. |
