Abstract

A connection system for connecting a structure fluid line on an offshore structure with a riser fluid line on a subsea riser. The system includes a connector attachable to the subsea riser and a gooseneck comprising a gooseneck connector in fluid communication with the structure fluid line. A frame is supportable on the connector and comprises a slide releasably engageable with the gooseneck and moveable within the frame. The slide is remotely controllable to move the gooseneck connector into and out of a connected position to establish or break fluid communication between the structure fluid line and the riser fluid line.

First claim

What is claimed is:

1. A connection system for connecting a structure fluid line on an offshore structure with a riser fluid line on a subsea riser, the system comprising:
a connector attachable to the subsea riser;
a gooseneck comprising a gooseneck connector connectable in fluid communication with the structure fluid line;
a frame supportable on the connector, the frame comprising a slide releasably engageable with the gooseneck and moveable within the frame; and
wherein the slide is remotely controllable to move the gooseneck connector into and out of a connected position to establish or break fluid communication between the structure fluid line and the riser fluid line.

2. The system of claim 1 wherein the connector comprises a connector hang off structure and the frame comprises a hang off frame to support the frame on the connector hang off structure.

3. The system of claim 1 wherein the connector comprises a riser fluid line connector in fluid communication with the riser fluid line.

4. The system of claim 1 further comprising multiple structure fluid lines, multiple riser fluid lines, multiple goosenecks, and multiple slides, the slides remotely controllable to move the goosenecks within the frame.

5. The system of claim 1 further comprising a control umbilical to control the position of the slide within the frame.

6. The system of claim 5 further comprising a control system in communication with the slide through the control umbilical.

7. The system of claim 1 further comprising more than one frame and more than one control umbilical.

8. The system of claim 1 wherein the slide is disconnectable from the gooseneck and the frame is removable from the connector with the structure fluid line in fluid communication with the riser fluid line.

9. The system of claim 1 further comprising an installation system to move the frame into supported connection with the connector.

10. The system of claim 1 wherein the gooseneck comprises a lock to lock the gooseneck in the connected position.

11. A method for connecting a structure fluid line on an offshore structure with a riser fluid line on a subsea riser, the method comprising:
connecting a gooseneck assembly to a frame, the gooseneck assembly being in fluid communication with the structure fluid line,
wherein the frame comprises a slide releasably engageable with the gooseneck assembly and moveable within the frame;

connecting the frame and the connected gooseneck assembly to the subsea riser; and
establishing fluid communication between the structure fluid line and the riser fluid line.

12. The method of claim 11 , further comprising disconnecting the frame from the gooseneck assembly.

13. The method of claim 12 , wherein the slide is remotely controllable to place the gooseneck assembly into and out of a connected position to establish or break fluid communication between the structure fluid line and the riser fluid line.

14. The method of claim 11 , wherein the frame connects to a connector attached to the subsea riser.

15. The method of claim 14 , wherein the connector comprises a connector hang off structure and the frame comprises a hang off frame to support the frame on the connector hang off structure.

16. The method of claim 11 , wherein the gooseneck assembly comprises a lock to lock the gooseneck in a connected position.

17. The method of claim 16 , further comprising actuating the lock by twisting.
