6 SERVICING & PRESSURE TESTING OF RETRIEVAL EQUIPMENT
All Retrieval Tools and Service Valves must be pressure tested prior to use. The Field
Technician using the equipment must possess current pressure test certificates for the
retrieval equipment prior to commencing on-line retrievals operations.
If the pipelines being worked on contain heavy debris, including, but not limited to; iron
sulphide, sand, solids and iron oxide, the tool may become contaminated and difficult to use.
The Field Technician will determine on a case by case basis if the tool needs to be stripped
down or if it can be flushed out with either water or suitable cleaning agent without stripping
the tools down.
At the end of each major service visit, the tools will be stripped down, cleaned, seals replaced
as necessary, re-assembled and pressure tested. See Section 6.2 for pressure testing
procedure.
