Analysis of precision of oil trunk pipeline position determination by C-SCAN device
Presented are measurements of trunk pipeline depth, made by C-SCAN device and by steel rod. It is noted, that indications of the device and the rod never have been congruent in full, moreover, difference in indications became more noticeable with pipeline depth increase. Conclusion is made on necessity of data accumulation and systematization by realizing parallel measurements by C-SCAN device and by rods or pits, so as to increase the accuracy of pipeline position determination.
