Pigging for Purpose: Selecting Pigs for Your Pipeline Needs
Pipeline pigs play a role both in the commissioning of new and renovated pipelines and in the operational maintenance of operational pipelines. During the pre- and commissioning phase of pipeline construction, specific pigs are used to prepare the pipeline for operation and to perform a baseline assessment for validation that the pipeline condition meets physical design specifications. Anticipating threats to the pipeline during operation will help determine the pigs to be used to keep the pipeline safe and to manage risk as low as reasonably practicable.
