| description | A system for surge protection of a riser 2 adapted to transport gas from a hydrocarbon production well. The system features flexible tubing 5, a portion of which extends into the riser and wherein the tubing terminates inside the riser. A pressure control system 7 creates a pressure differential within the flexible tubing such that liquid is drawn from the riser into the flexible tubing if liquid is present in the riser. The length of said portion of the flexible tubing is variable depending on the amount of liquid drawn into the flexible tubing. There is also provided a method of carrying out this system. Optionally, there is a control system arranged to increase the length of said section if the pressure in the tubing is below a first threshold level and to decrease the length of said section if the pressure in the tubing is above a second threshold level. Optionally a control system is arranged to increase the length of said section if the amount of detected fluid is below a first threshold level, or if no fluid is detected; or decrease the length of said section if the amount of detected fluid is above a threshold. |
