Abstract
A launch system for a pressurized pipeline includes a housing attachable to the pipeline such that an inside of the housing is open to an interior of the pipeline and an outside of the housing is exposed to an ambient environment outside the pipeline. A first actuator arrangement is disposed on the outside of the housing, and a second actuator arrangement is disposed on the inside of the housing. A seal arrangement is disposed in the housing between the first actuator arrangement and the second actuator arrangement. Each of the first and second actuator arrangements is configured to receive a cable having a portion extending outside the housing, a portion extending through the seal arrangement, and a portion extending inside the housing. The actuator arrangements are independently operable to pull the cable relative to the seal arrangement for moving the cable into and out of the pipeline.
