Claims20
A connector system, comprising:
- a first riser joint configured to form part of a riser and comprising a pin;
- and
- a connector configured to couple to a wellhead assembly and comprising a plurality of collet segments that are configured to move radially-inwardly to engage the pin of the first riser joint.
A subsea drilling system, comprising:
- a riser that extends between a platform at a sea surface and a wellhead assembly at a sea floor, wherein a distal end of the riser comprises a pin;
- and
- a connector coupled to the wellhead assembly, wherein the connector comprises a plurality of collet segments that are configured to move radially-inwardly to engage the pin to enable the connector to couple the riser to the wellhead assembly.
A method of coupling a riser and a wellhead assembly, the method comprising:
- moving a first riser joint of the riser toward a connector coupled to a portion of the wellhead assembly;
- inserting a pin of the first riser joint of the riser into an opening defined by a plurality of collet segments of the connector;
- and
- driving the plurality of collet segments to move radially-inwardly to engage the pin of the first riser joint of the riser to form a connection between the riser and the wellhead assembly.
