The purpose of this document is to provide guidance for the design and installation, maintenance, and operation of in-service pipeline pigging facilities. A pigging facility permits the operator to run pipeline pigs for corrosion control, in-line inspection, and flow assurance programs.
This engineering practice covers the design and installation of in-service pipeline pigging facilities for all new and existing pipelines. If there are conflicts between this specification, Owner’s requirements, Industry standards and regulatory requirement, the most stringent requirements shall apply.
This practice does not apply to temporary construction launchers/receivers or launchers/receivers for offshore use.
The installation of “temporary” pig traps shall be performed under the control of a MOC process that includes operations, engineering and safety design reviews.
