Abstract: System and method for mapping and/or inspecting an underground pipeline infrastructure. The system comprises a sensor probe for collecting geospatial data while travelling through a pipeline of the pipeline infrastructure, and a driving mechanism for driving the sensor probe. The sensor probe comprises a train of at least two modules of which a first module contains a sensor pay load for collecting said geospatial data and a second module is provided for connecting the sensor probe to the driving mechanism, wherein successive modules of said train are connected to each other by means of a flexible connection which allows the sensor probe to travel through pipeline bends, wherein each flexible connection comprises a spring configured for straightening the sensor probe and a flexible element mounted on the inside of the spring configured for bearing a predefined tensile load.

Abstract: Method and system for mapping and/or inspecting an underground pipeline infrastructure, using: a sensor probe for collecting geospatial data while travelling through a pipeline of the pipeline infrastructure, and a driving mechanism comprising a tether, for driving the sensor probe, wherein the sensor probe is provided to enter the pipeline at a vertical angle through a live-fluid entry apparatus and once inside the pipeline make a 90° angle change of direction to align with the orientation of the pipeline.
