Advanced data gathering system keeps all the information recorded, securing its further detailed analysis. Innovative approach within updated Piglet system is the use of optical fiber of 250 mm diameter, being in a moving module, instead of thick cables. Optical fiber coil unwinds while moving in the pipe line until the end of the maintenance room of it.
While Piglet module moving backwards optical fiber is collected in the temporary launching gear. New optical fiber coil is to be used for each new pipe survey. One of Piglet System advantages is a complete clearness of the process even for stubborn soiling.
