Risk of a stuck tool situation can be mitigated but never eliminated. Thus, using pig tracking systems during initial runs and especially in no-pigging-history pipelines is mandatory.

A pig tracking set consists of a low-frequency transmitter unit and handheld receiver antenna. The transmitter is installed on any pipeline pig and emits low-frequency signals that are detected by the receiver antenna carried by a pigging technician surveying the pipeline route. Thus, in case of a stuck pig situation, the location can be identified.

At LIN SCAN, we always use pig tracking units while performing inspection jobs. We sell these systems to our clients, encouraging them to achieve regular pigging operations safely. The systems are perfect for both intelligent and utility pigs.
