Energy services provider Expro has launched Velonix, an optimised pipeline pig control system that addresses the challenge of maintaining consistent pig velocity by automating and stabilising pigging operations
Pipeline integrity depends on accurate inline inspection (ILI) and effective pigging, both requiring pigs to travel within a critical velocity range. Deviations can cause stalled tools, missed contaminants, or incomplete data - compromising safety and compliance.
Velonix automatically controls pig velocity to help reduce re-runs, improve inspection data quality and enhance safety performance across low, high and no flow pipeline environments, combining state of the art SONAR measurement with automated closed loop flow control. The system integrates three key components: a clamp-on ActiveSONAR meter for continuous direct velocity measurement, computer-controlled throttling valves, and a purpose-built control unit for closed-loop regulation of pipeline flowrates and pressures. Combined with Expro's own Data to Desk platform, operators gain immediate visibility and control from any location or device, allowing for faster and more informed decision making and project visibility. This approach enables accurate velocity control under varying conditions, including high or low flow pipelines and alternative propellant scenarios. The system automatically adjusts pipeline flow through a digitally controlled skid to maintain pigs within the optimal velocity window throughout the run.
Maintaining consistent pig velocity when pipeline flow conditions are variable, constrained or absent is a persistent challenge for operators. By removing reliance on manual adjustment, the system reduces operational uncertainty, helps prevent inspection failures caused by speed excursions and avoids the need for costly and disruptive re runs, enabling customers to complete pipeline integrity campaigns more efficiently and with greater confidence.
“Pig velocity is one of the most critical factors in successful pigging operations, and Velonix provides operators precise, automated control over it,” said Andrei Ion, vice president of Well Flow Management at Expro. “After extension field testing, Velonix has consistently demonstrated its ability to deliver smooth, stable pig runs across a range of pipeline environments, maintaining target velocities, avoiding speed excursions and eliminating the need for costly re runs, increasing the reliability of pipeline intervention through data intelligent services.”
The introduction of Velonix reinforces Expro’s continued investment in intelligent automation and digital technologies to improve the safety and environmental performance of pipeline integrity operations
