Internal Inspection Tool: Pipeline Inspection Gauge (PIG)
The PIG applies the same LRU technology as the external nodes but is deployed inside the pipe, for more information on the external nodes click here. The iPIM-PIG leverages on the ability of LRU to reach areas not accessible to conventional probes; hence, this distinctive advantage will enable the inspection of previously unreachable areas.
For instance, the system has advantages in applications where there is a cylindrical structure that is either blocked or has no external access (e.g. pipes with obstructions or oil rig caissons and riser pipes). The modular PIG has the potential to cover a range of applications and can be used in a motorised, built-in or winched configuration.
