Surveying Capabilities

Prior to construction various surveys are conducted to determine the corrosion risks to a buried structure in a specific environment and to design any CP or ACM systems. We own equipment to perform all of the commonly performed surveys and ACE Technicians are proficient in the following:

• Soil resistivity surveys
• Soil corrosivity surveys (pH, SRB, soil-type analysis, etc.)
• Stray current surveys and Interference Testing (DC and AC)
• Current Drainage surveys
• Groundbed Surveys
• Coating defect surveys (DCVG, CIPS, PCM, etc.)
• Coating resistance surveys

ACE employs a number of full-time technicians with many years experience in the local Cathodic Protection Industry.

Our inventory of specialist equipment includes the following:

• Soil Resistivity Meggers
• MicroEye Voltage Data Loggers*
• PIM Direct Current Voltage Gradient (DCVG) Sets
• Radiodetection Pipeline Current Mapping (PCM) Sets
• Garmin Sub-metre Accurate GPS Receivers
• Synchronised Current Interrupters
• Portable DC Power supplies
• Soil Boxes, Reference Electrodes, Meters,etc.

* MicroEye Voltage Data Loggers are ACE’s proprietary high-accuracy digital data loggers which interface with our in-house developed data analysis and management software.

ACE has performed many pre-construction and maintenance surveys for gas, fuel and water pipelines for clients including Sasol Gas, PetroSA and DWA&F amongst others. Our Management has extensive experience in data collation and management as well as the logistics of data gathering on cross-country pipeline routes.
