Abstract: A running tool for coaxially setting together subsea wellhead housings, such as a high pressure wellhead housing within a low pressure wellhead housing. The tool includes a conically shaped body that is insertable within the inner most housing, a frame with a base, an axial bore and latches. The base perpendicularly rests on top of an inner housing and the latches extend from the base to connect with an outer housing. The bore is formed to accommodate the tool freely therethrough. Wedge shaped members are provided between the base and inner housing top having their wide ends contactable by the tool. Urging the tool through the bore pushes the wedges radially outward that imparts a force between the base and inner housing top in one direction. The attached latches apply an oppositely directed force onto the outer housing.

Abstract: A valve, such as a ball valve, is assembled and carried by a running tool. The valve is actuated by an actuator that is triggered by the running tool, and thus opens and closes communication between the drill pipe and the volume below the running tool. An actuating cam is assembled below the running tool that interfaces the actuator. The actuating cam is threaded such that it travels axially as the drill pipe is turned. A profile on the actuating cam is timed with the function of the running tool and controls the action of the actuator such that the valve is open when the running tool function requires communication with the volume below the running tool and the valve is closed when the running tool needs to be pressurized.

Abstract: A tieback connector connects a tieback conduit from an offshore platform to a subsea wellhead assembly. The tieback connector has a mandrel that is connected to a string of tieback conduit and a sleeve and load ring that are carried by the mandrel. The load ring is radially expansible and has a conical portion with internal threads. The load ring has an external grooved profile that engages an internal grooved profile in the subsea assembly. The mandrel is rotatable relative to the sleeve while in its lower position, causing the load ring to further expand outward into engagement with the internal profile. A locking member is carried below the load ring on an exterior cam surface of the mandrel. The cam surface moves the locking member outward when the mandrel moves downward into engagement with an internal profile in the subsea assembly.
