Choke and Kill Stab
Patent 11/895,692
Choke and Kill stabs are used on subsea BOP stacks. They provide a high-pressure fluid connection between the lower BOP and the LMRP. Our patent pending design has an extremely low separating force between the male and female receptacle. It is similar to a pressure-balanced ROV stab, except it is specifically designed to the choke/kill line application.
It cannot get stuck during an emergency disconnect event.
Applications
- BOP Stacks
- Production Trees, manifolds and tie-ins
