Abstract
There is provided an apparatus for tracking a pig travelling inside a tubular object. The apparatus includes a sensor arrangement including at least one position sensor configured to detect a passage of the pig travelling inside the tubular object and a tracking device. The tracking device is configured to: process the detected passage of the pig from a run of the pig through the tubular object to determine a travel time of the pig; using the determined travel time, calculate a speed of the pig through the tubular object; and using the calculated pig's speed, perform real-time tracking of the pig's position inside the tubular object in a subsequent run of the pig through the tubular object.
