Tubing Riser

Riser which consists of one or more individual strings of production tubing and a hydraulic control umbilical.

NOTE If multiple tubing strings are used, they can be left either independent of each other, or secured together using some type of clamping device. The hydraulic control umbilical is normally clamped or strapped to one of the tubing strings as it is run.
