PR-472-144505-R04 Guidance on Subsea Launchers and Receivers

The purpose of this document is to provide information on the components and procedures that must be considered when conducting a pigging operation on a subsea pipeline system. All of the considerations discussed in this document should be addressed in order to successfully implement a subsea pipeline pigging project. Phases of a pigging project (pre-commissioning, cleaning, in-line inspection and maintenance), planning and project execution are addressed. This document compliments the other reports produced as part of PRCI project SPDA-1-4, which focus on subsea pig launching and receiving.
