Subsea/EX Pig Trackers – Designed, validated and manufactured by Petritek and deployed on licence by Radiation Professionals Australia
What is Pig Patrol?
An evolutionary shift in pipeline pig location and transit verification. Pig Patrol location method utilises a small sealed radioactive source attached to each pig and is designed specifically to meet the project work scope.
This allows for accuracy of location within centimetres as well as verified transit during launch and receival. Pig Patrol is fixed to the external pipe location of interest to monitor the passage of each pig.
Eliminatethe risk of lost pigs
Oil and Gas pipe lines require periodic inspections and cleaning to ensure the company’s assets are maintained and optimized. These pipe lines can be surface or sub sea.
Pigs are sent along the internal pipe line to clean and gather information and play and essential role in the maintenance of these pipelines for the life of the project.
The operator when using these pigs require tracking to ensure confidence that each pig has been successfully launched, traversed and received at specific locations along the pipeline route.
Delays and related costs incurred locating lost or stuck pigs can be onerous, these can also be reduced significant with the consistent and low risk reliability of Pig Patrol.
EVOLUTION IN DATA AND COMPLIANCE
Expertise in multi-disciplinary instrumentation, data acquisition and analysis in harsh and demanding environments has informed R & D to deliver this next generation in gamma technology. The added in-field experience with global operators and world-class assets has ensured an informed performance meeting everyone’s expectations.
Utilising smart algorithms, reduced gamma-sources and increased instrumentation sensitivity, Pig Patrol will improve regulatory compliance, HSE and operational performance metrics whilst getting the job done.
USING PIG PATROL FOR SUSBEA NORM
Just as with topside pipework, NORM can also accumulate in subsea pipelines. The accumulation of NORM can greatly influence the decommissioning and abandonment of subsea pipework on the seabed. When any subsea equipment such as flexible risers or manifolds, are retrieved from the seabed, there is a potential for accumulation of NORM within the internal surfaces. Being able to ascertain the presence of significant build-up of NORM can greatly mitigate the risk of exposure to personnel and impact on the environment.
Though Pig Patrol was initially designed for tracking pigs with on-board radioisotopes, the smart algorithm and outstanding performance of the detection system allows the use of the Pig Patrol for detection of significant NORM in subsea pipelines. Allowing the operator to make informed decisions for future work in the field.
