Claim 12:
13. The method of claim 12, further comprising:
determining a second tube angular position of a second process tube in the first header pipe or a second header pipe;
after performing the service method on the first process tube, removing the header delivery system from the first header pipe with the header delivery system in the retracted position;
after removing the header delivery system from the first header pipe, positioning the base assembly with respect to the first rotation apparatus and the second rotation apparatus to position the header delivery system in a second angular position;
connecting the base assembly to the first rotation apparatus and the second rotation apparatus to fix the header delivery system in the second angular position;
after fixing the header delivery system in the second angular position, inserting the header delivery system in the first header pipe or the second header pipe with the tube coupler in the retracted position;
aligning the header delivery system in the first header pipe or the second header pipe with the second process tube and with the tube coupler in the retracted position;
after aligning the header delivery system, actuating the jack apparatus to position the tube coupler from the retracted position to the extended position to form a seal between the tube coupler and the second process tube; and
performing a second service operation on the second process tube coupled to the header delivery system using the launcher pipe for access to the second process tube.
