A rigid chain actuator () including a tool body () having a bore () with a chain () at least partially disposed in a housing () coupled to the tool body. Additionally, the rigid chain actuator includes a chain extension/retraction mechanism to extend the chain from the housing into the bore and recoil the chain from the bore into the housing. Furthermore, the chain may translate a force onto at least one wellbore tool through the bore.

Plug retrieval and installation mechanism

A system is provided to perform various wellbore operations, including retrieval and replacement of solid internal tree caps, for example. The system may include an open water lubricator having a piston assembly disposed therein. The system may also include a well control package connected to a distal end of the open water lubricator. The piston assembly is configured to extend through the well control package. Method using systems disclosed herein may be performed while maintaining at least two testable pressure barriers during each of the retrieving and replacement steps.

Large bore open water lubricator

A system for forming an upper plug in a well, the system, comprising lower tool segment that is adapted to land within a wellhead housing under open water conditions, a well control package that is adapted to be positioned above the lower segment and coupled to the wellhead housing, the well control package comprising at least one seal ram, an upper tool segment that is adapted to be positioned through the well control package (i.e., after the well control package has been attached to the wellhead) and operatively coupled to the lower tool segment, wherein at least one seal ram of the well control package is adapted to engage an outer surface of the upper tool segment, and at least one cutting means that is coupled to the lower segment and adapted to be actuated to cut at least one opening in at least one section of casing within the well.
