Pigging Operations

• Cleaning pigging: a device known as a pig is inserted into the pipeline and pushed along by the flow of the product (liquid or gas). The pig scrapes the inner walls of the pipe, removing debris, sediment and other contaminants.
  
  
• Inspection pigging to assess the condition of the pipeline and detect defects, corrosion or other anomalies. Intelligent pigs equipped with sensors and cameras are used to identify areas in need of maintenance or repair.
  
  
• Pre-commissioning pigging: pigs are run through the pipeline to remove any construction debris or obstructions. This technique ensures the integrity and cleanliness of new pipelines and is necessary before a new pipeline is put into service.
  
  
• Maintenance pigging: the pig is pushed through the pipeline at regular intervals. This prevents the build-up of debris, corrosion or scaling, extending the life of the pipeline and ensuring its optimal operation.
  
  
• Decommissioning pigging removes any remaining product or other substances from a pipeline that is no longer in use. This ensures the pipeline can be safely taken out of service and minimises the environmental impact.
