ZAKCO provides specialized pipeline surveys to monitor the efficiency, productivity and output of Cathodic Protection systems.This is essential to any Cathodic Protection program and ensures the continued operation of your facility.

Soil Resistivity

Soil resistivity surveys plays vital role for cathodic protection (CP) design. The amount of current required for effective protection of the system can be derived based on the soil resistivity. The soil having low resistivity will require more current than high resistivity soils to achieve the same level of protection, which will further influence the CP system sizing.

CIPS

Close interval potential survey is carried over the entire length of the pipeline to identify the if the installed CP system is providing the required protection against external corrosion.

Current Attenuation Test (CAT)

The main objective of CAT Survey is,

• To identity of pipeline sections where coating deterioration is expected.
• To estimate the health of the pipeline coating.

Direct current voltage gradient (DCVG)

A direct current voltage gradient (DCVG) survey is a type of survey method that is used to find the effectiveness of coating on buried pipelines. This is highly useful in the natural gas and oil industries, as this technique is used to trace and pinpoint the coating faults.

External Corrsion Direct Assessment (ECDA)

The assessment involves estimating the remaining life of the existing structure and the remaining strength.
