Abstract
A diverter system having stabbing dogs is provided. In one embodiment, such a system includes a diverter, a housing, and a plurality of stabbing dogs coupled to the housing. The stabbing dogs are positioned to enable locking elements of the stabbing dogs to be extended into recesses in the diverter to secure the diverter within the housing. At least one of the recesses in the diverter is connected to a fluid conduit within the diverter, and at least one stabbing dog includes a fluid passage that enables fluid to be routed into the fluid conduit within the diverter through the at least one stabbing dog. Additional systems, devices, and methods are also disclosed.
Claims18
A system comprising:
- a diverter;
- a diverter housing;
- and
- a plurality of stabbing dogs coupled to the diverter housing and positioned to enable locking elements of the plurality of stabbing dogs to be extended into recesses in the diverter to secure the diverter within the diverter housing, wherein at least one of the recesses in the diverter is connected to a fluid conduit within the diverter and at least one stabbing dog of the plurality of stabbing dogs includes a fluid passage that enables fluid to be routed into the fluid conduit within the diverter through the at least one stabbing dog.
A system comprising:
- a diverter including hydraulic functions;
- and
- a housing having locking dogs for retaining the diverter within the housing, wherein the locking dogs include hydraulic stabs configured to route hydraulic control fluid into the diverter to enable control of the hydraulic functions of the diverter;
- wherein the hydraulic functions of the diverter include closing an annular preventer of the diverter, opening the annular preventer, and energizing flowline seals to seal the diverter against the housing.
A method comprising:
- positioning a diverter within a housing;
- extending a locking dog to retain the diverter in the housing, wherein extending the locking dog also connects a fluid conduit within the locking dog to a fluid conduit within the diverter;
- and
- routing hydraulic control fluid through the fluid conduit within the locking dog to close a packer within the diverter.
A method comprising:
- positioning a diverter within a housing;
- extending a locking dog to retain the diverter in the housing, wherein extending the locking dog also connects a fluid conduit within the locking dog to a fluid conduit within the diverter;
- and
- routing hydraulic control fluid through the fluid conduit within the locking dog to energize flowline seals between the diverter and the housing.
