Adjustment and repositioning of coiled tubing tensioning device while deployed

An adjustable coiled tubing deployment apparatus, comprising:

• a tubing guide for receiving a coiled tubing;
• a tensioning device for maintaining the coiled tubing in tension, where the coiled tubing is directed into the tensioning device from the tubing guide;
• and
• a tower frame having a moveable platform supporting the weight of the tensioning device, the moveable platform comprising an upper carriage section, a lower carriage section, and one or more vertical actuators, the moveable platform adjustable vertically to raise and lower the tensioning device with respect to the tower frame, wherein:
• the tower frame comprises at least two longitudinal support rails each having a plurality of apertures spaced along a longitudinal length of each of the longitudinal support rails;
• and
• the upper carriage section and the lower carriage section each contain two or more pegs which are horizontally actuatable to engage at least one aperture of the plurality of apertures of each of the longitudinal support rails, thereby forming the moveable platform for supporting the tensioning device.

A method, comprising:

• deploying a coiled tubing through a tensioning device, the tensioning device supported by a moveable platform coupled to a tower frame, the moveable platform comprising an upper carriage section, a lower carriage section, and one or more vertical actuators, and the tower frame comprising at least two longitudinal support rails each having a plurality of apertures spaced along a longitudinal length of the longitudinal support rails;
• locking the tensioning device into a fixed position with respect to the tower frame by extending two or more horizontally actuatable pegs from the upper carriage section and the lower carriage section such that each horizontally actuatable peg engages an aperture of the plurality of apertures spaced along the longitudinal support rails;
• and
• adjusting a height of the tensioning device with respect to the tower frame by:
• retracting the horizontally actuatable pegs of the upper carriage section from the apertures of the longitudinal support rails;
• actuating the one or more vertical actuators to raise or lower the upper carriage section with respect to the lower carriage section and the tower frame, wherein the lower carriage section supports a weight of the tensioning device and the upper carriage section during the actuation;
• and
• extending the horizontally actuatable pegs of the upper carriage section to engage with apertures of the longitudinal support rails and lock the upper carriage section in place at a desired adjusted height.
