Tank Drop Off System

Overview and System Demonstration

A Tank Drop-off System is similar to a standard single-pig system, but incorporates multiple destinations on the same line to deliver product to. There is no limit on the amount of drop-offs that can be used.

How a Tank Drop Off Pigging System Works

After a transfer to a tank, the automatic pigging sequence sends a pig to the blocking valve for that tank. Any blocking valves between the destination and the pig are opened to allow for a clear route. The pig is then returned with the same receive-return pigging station used on a single-pig system.
