Creating or restoring safe access to pipelines for pig loading or removal operations
Overview:
The inability to access existing pig launching and receiving facilities due to inadequate isolation capability is a common access constraint for pipelines. The lack of adequate isolation valves or pipelines where launchers or receivers are absent can result in essential pigging activities being delayed or conducted less frequently than required.
Abstract
This presentation will explain how the appropriate application of temporary double block and bleed pipeline isolation tools, and if required hot tapping intervention techniques, can be used to create or restore safe access to pipelines for pig loading and removal operations.
The presentation will be supported with industry examples and case studies demonstrating how safe access for pigging operations can be provided cost effectively, and without affecting production or depressurising the pipeline.
