The installer includes a base having a tubular connector extending downward for connection to an upper end of a blowout preventer. Hydraulic cylinders are mounted to and extend upward from the base. A support floor having support slips is mounted to the hydraulic cylinders at a fixed distance above the base. A traveling slip base containing traveling slips is mounted to upper ends of piston rods of the hydraulic cylinders. A pipe lifting assembly is supported by the base for lifting and positioning an additional joint of tubing to be added to the string of tubing. A pipe make-up mechanism is supported by the base for rotating the additional joint into threaded engagement with the string of tubing. A control line supply source for supplies control line to and alongside the string of tubing at a point between the base and the support floor.
