Systems and methods for riser coupling
View Patent ↗Systems and methods for riser coupling are disclosed. A riser coupling system comprises a riser joint connector comprising a first tubular assembly coupled to a second tubular assembly. The riser coupling system further comprises a spider assembly which receives the riser joint connector and has a connector actuation tool. The connector actuation tool comprises a dog assembly, a clamping tool and a splined member. The dog assembly selectively extends a dog to engage the riser joint connector. The clamping tool couples the first tubular assembly and the second tubular assembly. Finally, the splined member actuates a locking member of the riser joint connector.
1. A riser coupling system, comprising:
a riser joint connector comprising:
a first tubular assembly;
a second tubular assembly;
a cam ring having an upper member and a lower member, wherein the upper member and the lower member are adjustable to retain the first tubular assembly and the second tubular assembly together;
a locking member adjustable to retain the cam ring in a locked position; and
a lock ring, wherein movement of the upper member of the cam ring and the lower member of the cam ring toward each other locks the lock ring;
a running tool configured to move the first tubular assembly into orientation with the second tubular assembly; and
a spider assembly to receive the riser joint connector, the spider assembly comprising a connector actuation tool, wherein the connector actuation tool comprises:
a dog assembly configured to selectively extend a dog to engage the riser joint connector;
a clamping tool to actuate the upper cam ring member and the lower cam ring member of the riser joint connector; and
a splined member to actuate the locking member of the riser joint connector.
2. The riser coupling system of claim 1 , wherein the spider assembly is remotely operated.
3. The riser coupling system of claim 1 , wherein the dog assembly further comprises a piston assembly, wherein the piston assembly is operable to extend the dog to engage the riser joint connector.
4. The riser coupling system of claim 3 , wherein the piston assembly is hydraulically driven.
5. The riser coupling system of claim 1 , wherein the clamping tool comprises an upper actuation piston, an actuation piston mandrel and a lower actuation piston.
6. The riser coupling system of claim 1 , wherein the splined member is extendable.
7. The riser coupling system of claim 1 , further comprising a sensor, wherein the sensor detects position of at least one of the dog, the clamping tool and the splined member.
8. The riser coupling system of claim 1 , wherein the connector actuation tool further comprises a motor and wherein at least one of the clamping tool and the splined member is driven by the motor.
9. A riser coupling system, comprising:
a riser joint connector comprising:
a first tubular assembly coupled to a second tubular assembly;
a cam ring having an upper member and a lower member, wherein the upper member and the lower member are adjustable to retain the first tubular assembly and the second tubular assembly together; and
a lock ring, wherein movement of the upper member and the lower member toward each other locks the lock ring;
a spider assembly having a connector actuation tool, wherein the spider assembly receives the riser joint connector and wherein the connector actuation tool comprises:
a dog assembly, wherein the dog assembly selectively extends a dog to engage the riser joint connector;
a clamping tool, wherein the clamping tool couples the first tubular assembly and the second tubular assembly; and
a splined member, wherein the splined member actuates a locking member of the riser joint connector.
10. The riser coupling system of claim 9 , wherein the clamping tool actuates at least one of the upper member and the lower member of the cam ring.
11. The riser coupling system of claim 9 , further comprising a running tool, wherein the running tool moves the first tubular assembly into orientation with the second tubular assembly.
12. The riser coupling system of claim 11 , wherein at least one of the running tool and the spider assembly is remotely operated.
13. The riser coupling system of claim 9 , wherein the dog assembly further comprises a piston assembly, wherein the piston assembly is operable to extend the dog to engage the riser joint connector.
14. The riser coupling system of claim 13 , wherein the piston assembly is hydraulically driven.
15. The riser coupling system of claim 9 , wherein the clamping tool comprises an upper actuation piston, an actuation piston mandrel and a lower actuation piston.
16. The riser coupling system of claim 9 , wherein the splined member is extendable.
17. The riser coupling system of claim 9 , further comprising a sensor, wherein the sensor detects position of at least one of the dog, the clamping tool and the splined member.
18. The riser coupling system of claim 9 , wherein the connector actuation tool further comprises a motor and wherein at least one of the clamping tool and the splined member is driven by the motor.
