Pipeline pigging is actually a form of flow assurance for O&G pipelines and flowlines. This is because the use of pipeline pigging helps maintain subsea pipelines clear of unwanted material or debris that may build up in a pipeline and eventually cause the passage of O&G to slow or even stop altogether if the pipeline is plugged with these materials. This unwanted debris, such as wax and paraffin, when obstructing a pipeline's flow, may cause the subsea pipelines to crack, by increasing the pressure in the pipeline. A highly clogged pipeline section may also cause damage to other sections of the same pipeline, due to pressure increase along the line caused by the decrease in flow along the clogged pipeline section.

PipeWay is also a spinoff from the Genesis Institute run by PUC University in Rio de Janeiro. PipeWay Engeneering is the only company in the Southern Hemisphere with fully national production, which manufactures and operates tools for O&G pipeline inspection, which check anomalies such as oval pipes, crushing and corrosions, contributing to avoid leakages that may cause environmental accidents and safety hazards. PipeWay entered the O&G market in 1998, when the group of researchers from the Pontifical Catholic University of Rio de Janeiro (PUC-Rio), by using the technology of Petrobras' Research and Development Center (CENPES), launched a tool for pipe integrity management.
