Pig Launch Indication It is a common Operator requirement to accurately determine when a pig has been launched successfully. This is usually monitored at a number of locations during launch operations: • Pig exiting the launcher • Pig entering and leaving first valve • Pig having left the launch site The method discussed will illustrate how non-intrusive magnetic signallers can accurately determine the success of a pig launch. www. online-electronics. com

Subsea Pig Monitoring Magnetic Signalling Subsea to Vessel (Reference: Heimdal to Brae Project) www. online-electronics. com

Pig Passage Indication Subsea Non-intrusive pig signalling methods can also enable monitoring of subsea pig passage remotely from a vessel. • Receive an acoustic or electromagnetic signal via ROV umbilical. • Having a diver/ROV monitor a signaller display • Transmitting the data autonomously using acoustic technology www. online-electronics. com

Buried Line Pig Monitoring Remote Pig Tracking: Reference: BP CATS Trans Alaska Pipeline www. online-electronics. com

Remote Pig Tracking To remotely monitor pigs passing certain points onshore, the information needs to be transmitted from the point of pig passage on the pipeline to the location of the operator which in practice could be many miles apart. Two methods of data communication were employed: – GSM unit connected directly to signaller/receiver which transmits information directly to an operator’s phone – Remote EM Receiver which receives information from an antenna on a pipeline and then transmits this information via a company network or GSM. www. online-electronics. com
