FASTRA Successfully Recovered a Stuck Intelligent Pig from a DN400 High-Pressure Gas Pipeline

During the operation of a DN400 high-pressure gas pipeline in Lithuania, FASTRA, s.r.o. was called by the customer in to address an unusual situation where an intelligent pig became stuck inside the pipeline, preventing further movement and requiring immediate technical intervention. To ensure a safe and controlled solution, FASTRA performed a double-sided line stopping operation. A DN150 bypass was subsequently installed to maintain continuous gas flow during the intervention.

A hose bypass system was utilized, providing a reliable and efficient solution. Once the pipeline section was isolated and the bypass fully operational, FASTRA carried out a precise cut on the affected section containing the stuck device. The intelligent pig was safely recovered, allowing for restoration of the pipeline. Following completion of the works, the pipeline was returned to full operation. This intervention demonstrates FASTRA’s ability to combine proven technologies with experienced personnel when addressing complex and unforeseen situations. The capability to perform such operations without a full shutdown is essential for maintaining operational continuity and minimizing disruption.
