In case of instant jamming, the first station stops pumping. The personnel of the ball tracking team shall judge the blocking position of the pig according to the pipeline throughput and pressure distribution. After the pigging personnel confirm the blocking position. They shall timely make fixed marks and report to the superior management department. Notify the oil transportation dispatching and rescue team as soon as possible. Then they work out the emergency repair plan according to the site conditions.
