n !i NATIONAL National Corrosion <br />CORROSION www.notional-corrosion.com <br />• Pipe support assessment <br />• Corrosion potentials of supports and pipeline potentials <br />• Upstream and downstream soil -to -air interface descriptions <br />• Dry film thickness (Coating) at locations 12, 3, 6, and 9 o clock <br />• UT (Ultrasonic) measurements at locations 12, 3, 6, and 9 o clock <br />• Insulator potentials and AC potential <br />Water depth <br />Photographs with info <br />• Sub -meter GPS coordinates <br />• Corrosion Severity Code (Define and classify priority actions) <br />o Perform atmospheric assessments at key locations <br />o Conduct current requirement testing to verify current needed to bring pipe -to - <br />soil potentials up to NACE criteria. <br />o Create a scope of work for improvements or repairs required to improve <br />corrosion assessment. <br />o Verify the existence and location of stray DC currents affecting the pipelines at <br />locations nearforeign impressed current cathodic protection systems. <br />o Test and verify dielectric isolation from foreign structures. <br />o All data to be ArcGIS compatible <br />o Create coating specifications and repair procedures <br />Task 3 — Integrate testing data into ArcGIS system <br />Field testing data will be recorded in a format compatible with ArcGIS. If ArcGIS implementation <br />is approved, then all data will be uploaded to a server. All activity will actively update during <br />repairs or modifications and the condition of facilities can be monitored remotely. <br />ArcGIS data will be recorded in a method that will aid estimation of coating and <br />mechanical repairs. <br />• All locations for repair will be prioritized and backed up with data <br />Task 4 —Corrosion Report (Deliverable) <br />After all field testing, inspection, and analysis is complete, a drafted report will be prepared <br />including the following: <br />• Description of testing procedures and tabulation of data <br />• Summary of test points showing GIS Coordinates along with identification <br />• Site photos <br />• Evaluation and assessment of active corrosion, status, and operational condition. <br />• Conclusions on as -found conditions <br />• Calculation of remaining life expectancy <br />• Prioritized recommendations of repairs or replacements. <br />• System operation and maintenance procedures <br />• Corrosion control plan to address immediate and long-term requirements <br />• Prepare a list of other cathodic protection systems owned by others that may cause <br />interference or require a coordination of efforts. <br />
