Pig Tracking

Problems Pig stuck / lost in the

line. Through wall communication has

become critical criteria for pigging systems.

3

Solution Accurate tracking &

detection. .

Bi-directional Communication

The Solution

High Accuracy Tracking & Detection

Real Time Monitoring

4

• Through-wall communication system.

• Accurately tracks, detects, positions and provides real-time monitoring.

• • Operator flexibility to reconfigure • parameters.

• • Used in onshore / offshore environments.

• Eliminates use of radioactive isotopes.

SmartTrack™ System Overview

Battery Conservation

Battery power can be conserved by switching transponder to dormant mode.

Operating mode (e.g., dormant / active) of transponder can be changed while it is in the pipeline

Activates/ deactivates transponder.

Transmitted data can be stored and displayed remotely.

Monitors internal pressure or temperature.

Signal can be relayed using subsea acoustic communication (up to 5 km (3.1 mil) or topside radio link (up to 80 km). 6

Key Differentiators

RemoteControl

Real-timeMonitoring

Accurate Tracking

Pig can be located within 2 inches of its location.

Signal from multiple pigs can be detected simultaneously.

SmartTrack™ Transponder

• Each transponder has a unique identity code that makes it possible to identify each pig.

• Identify up to 16 pigs

• Batteries last longer (365 days or more) in dormant mode.

• May be used as a pig body.

• Retrofitted for use with cleaning or inspection.

• DNV 09 ATEX 55935X

• Zone 1, Ex d IIB T6

15

Situation: Riser damaged on North Sea platform.

Challenge: Repair riser, replace topside pipework production system while maintaining production.

Solution:

•Isolate damaged riser section from gas inventory with three high friction pigs.

•SmartTrack™ system tracks pigs, monitors pipeline pressure during repair work while maintaining flow.

Results:

•Riser repaired while gas flowed.•Reduced downtime = reduced costs.•No impact on environment.

Case Study

16

• Most advanced tracking system.

• Tracks with pinpoint accuracy.

• Reliably monitors internal conditions.

• Enables change of operating parameters during operation.

• Highly versatile.

• Field-proven = 300+ interventions.
