Field Surveys

What services do we offer?pipeline integrity, cathodic protection, CIPS, DCVG, PCM, pipeline location, soil resistivity, chemical analysis, coating inspection
Elsyca has a team of cathodic protection specialists with extensive experience to meet the highest requirements in coating field surveys and ECDA CP. Our capabilities include:

  • Pipeline location;
  • Soil resistivity/chemical analysis;
  • Coating inspection;
  • Electrical isolation measurements;
  • On/off potential measurements;
  • CIPS, DCVG, PCM;

 

In addition, Elsyca has developed a unique capability for cathodic protection pipeline network modelling through its flagship software Elsyca CatPro. Please read further below how this technology helps to improve field surveys.

 

What value do we bring ?

At the core of the Elsyca CP field testing team are experienced NACE specialists. Experience and engineering insight are key to ensure a sound understanding of field survey results and therefore data quality. Our experience includes:

  • Soil Corrosivity Surveys (ASTM G57 Wenner Four, Ohm_Mapping and Soil Sampling and Analysis (DIN 50929-3)) for both pipeline routing and anode ground bed locations;
  • Pipe-to-Soil Potential Surveys (both static and dynamic using scope meters and/or data loggers (AC and DC)), which incorporate stray current interference surveys (transit and ICCP), polarized or “IR Free” potential surveys, AC potential surveys;
  • Current Drainage Tests (CDT) to determine the coating conductance of buried pipelines and to determine interference factors and “deleterious” current drains;
  • Pipeline Current Mapping (PCM) Surveys to determine the coating quality and any deleterious locations (coating defects and “unwanted earths”). In addition to this, the data can be inputted into BS PD8010 or ASME B31 as part of the pipeline assessment requirements;
  • All required surveys for input into BS7361-1, EN 13636:2004 - Cathodic protection of buried metallic tanks and related piping, EN 14505:2005 - Cathodic protection of complex structures, EN 50162:2004 - Protection against corrosion by stray current from direct current systems, with the objective of designing, auditing, and validating a detailed cathodic protection system.


Elsyca CatPro’s unique pipeline network modelling technique allows improving the efficiency of survey/pre-survey campaigns thanks to:

  • identifying danger/high risk zones and prioritizing field surveys accordingly;
  • tracing of anomalies through real-life data comparison with computer-simulated surveys;
  • optimizing pipeline integrity management by adopting codes of best practice that are backed by fundamental research technology.
