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.
