Troubleshooting pipeline losses involves an understanding of the loss/gain process, and requires collecting and analyzing data, interviewing measurement personnel, and visiting measurement facilities to assess equipment performance and witness measurement activities. Ultimately, loss investigations should include a conclusion of the findings along with recommendations for correction and improvements. The examples in this paper are drawn mostly from pipeline operations, but the principles apply to any system, which includes (1) measurement into the system, (2) measurement out of the system, and (3) inventory within the system (including tanks, vessels, reservoirs, system piping, etc.). Such systems include pipelines, marine terminals, marine voyages, bulk loading or storage terminals, tank farms, rail and trucking systems. Some change in loss/gain performance may be possible through improved procedures and better or more frequent calibration of equipment. But, major changes in "normal loss/gain" may require more or better equipment. Then it is a matter of economic justification. The cost to the system due to its losses may justify better equipment. In any event, a well-designed, up-to-date monitoring procedure can describe the normal performance of a transportation or storage system, and can identify problems that need attention.
