Each year, every pipeline operator must assess the integrity of their pipeline system. Assessment programs range from a few lines for some operators to hundreds for other larger operators. For most operators with piggable pipelines, inline inspection (ILI) tools are usually the preferred assessment method. However, the road to a successful inspection run has many pitfalls. Pipeline operators must do as much as possible to reduce the likelihood of run failures due to operational problems or errors. The cost to run an inspection tool is high enough, but coupled with a failure where the pipeline operator was at fault only multiplies the cost. A consistent planning procedure developed by the operator can be a key component to obtaining first-run success. There are a number of pipeline operational factors that should be part of the preparation assessment.
