5 . The connection system of claim 1 , wherein the plurality of bottom flange ports connect to one or more of a choke line, a kill line, a booster line, and a hydraulic line of a subsea blowout preventer disposed at or near a subsea surface of a wellbore.
6 . The connection system of claim 1 , wherein the plurality of bottom flange ports connect to one or more of a circulation line and a relief line.
7 . The connection system of claim 1 , wherein the plurality of bottom flange ports connect to one or more of a bearing umbilical, a rotating control device umbilical, an active control device umbilical, a control umbilical, a valve umbilical, or other umbilical.
8 . A connection system riser joint for a managed pressure drilling system comprising:
an inner barrel configured to reciprocate within an outer barrel; a packer disposed at a top distal end of the outer barrel; a tension ring configured to support the packer; a connection hub flange comprising a plurality of pass-through ports and a plurality of hub flange ports; a connection hub ring removably disposed around an outer surface of the connection hub flange, the connection hub ring comprising:
a plurality of dogs configured to removably attach the connection hub ring to the outer surface of the connection hub flange, and
a plurality of stab-in connectors disposed around an outer surface of the connection hub ring;
a bearing ring configured to movably attach the connection hub ring to the tension ring; a ported bottom flange connected to the bottom distal end of the outer barrel, the ported bottom flange comprising a plurality of bottom flange ports; and a plurality of conduits that connect the plurality of connection hub flange ports to the plurality of bottom flange ports, wherein the plurality of stab-in connectors are connected to the plurality of connection hub flange ports by the plurality of pass-through ports.
9 . The connection system riser joint of claim 8 , further comprising:
a top flange attached to a top distal end of the inner barrel.
10 . The connection system riser joint of claim 8 , further comprising:
a plurality of drape hoses, wherein each drape hose has a first distal end connected to a stab-in connector from the plurality of stab-in connectors and a second distal end connected to a device or system disposed on a platform of a floating rig.
11 . The connection system riser joint of claim 8 , wherein the packer comprises a plurality of seals.
12 . The connection system riser joint of claim 8 , wherein the ported bottom flange is configured to connect directly or indirectly to an annular sealing system of a marine riser.
13 . The connection system riser joint of claim 8 , wherein a top side of the connection hub ring is attached to a first side of the bearing ring and a second side of the bearing ring is attached to a bottom side of the tension ring.
14 . The connection system riser joint of claim 8 , wherein the connection hub ring, the plurality of drape hoses, and the plurality of conduits are preinstalled before installation of the managed pressure drilling system.
15 . The connection system riser joint of claim 8 , wherein the plurality of bottom flange ports connect to one or more of a choke line, a kill line, a booster line, and a hydraulic line of a subsea blowout preventer disposed at or near a subsea surface of a wellbore.
16 . The connection system riser joint of claim 8 , wherein the plurality of bottom flange ports connect to one or more of a circulation line and a relief line.
17 . The connection system riser joint of claim 8 , wherein the plurality of bottom flange ports connect to one or more of a bearing umbilical, a rotating control device umbilical, an active control device umbilical, a control umbilical, a valve umbilical, or other umbilical.
18 . A method of retrofitting a managed pressure drilling system for use with a connection system comprising:
attaching a connection hub flange to an outer barrel of a telescopic joint; attaching a ported bottom flange to a bottom portion of the telescopic joint; connecting a plurality of hub flange ports of the connection hub flange to a plurality of bottom flange ports of the ported bottom flange with a plurality of conduits; attaching a first side of a bearing ring to a bottom side of a tension ring; attaching a second side of the bearing ring to a top side of a connection hub ring; and disposing the tension ring, bearing ring, and connection hub ring around the telescopic joint below a packer of the telescopic joint.Join the waitlist — get patent alerts
