MEASURE TWICE, CUT ONCE

摘要

Marcus Veltman, Inline Pigging Solutions, Canada, emphasises the importance of precise planning and organising for successful digs and inline inspection. In front of you is an open excavation: protective coatings have been removed and non-destructive examination (NDE) is seeking out the specific anomalies planned to inspect. Something is not adding up. The anomalies are not where they are supposed to be. The clock position of the long seam is checked and compared to the tool inspection logs. This simple check indicates the dig site is not correct and your dig survey is out by three full joints of pipe. The correct dig site is well beyond the proximity that agreements and land permissions will allow. This excavation will have to be remediated and planning will have to start all over again.
