Abstract
A method of introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first drilling nipple attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing attached to the first drilling nipple by using a first manipulator located in the first air lock housing. The duct rod is advanced within pressurized gas pipeline by a driving mechanism, until a second drilling nipple is reached. The translating member is attached to a fiber optic conduit. The duct rod and fiber optic conduit are then pulled back or pulled forward through the pressurized gas pipeline by the driving mechanism.
