Evaluation and Monitoring of Cathodic Protection (CP) System

Data Management Solutions

Cathodic Protection is a procedure performed as an attempt to protect an object from corrosion by making it a cathode. It is done by applying direct current onto a metal object which is in contact with the electrolytic.

Cathodic Protection offers adequate corrosion control on steel structures and pipelines by developing a potential (voltage) gradient opposing the flow of ions away from the surface. In this way, it prevents the anodic corrosion reaction and can be used alone or in combination with an insulating coating.

Velosi offers a range of cost-effective Cathodic Protection methods to control the corrosion of various buried and submerged metallic structures. It is one of the effective ways to enhance the life of a structure, ensuring integrity throughout its life cycle.

Methods of applying Cathodic Protection include:

Sacrificial Anode System
Impressed Current System

At Velosi, the Cathodic Protection protocol is divided into two segments, such as:

Data Review and Engineering Works
Fieldworks that comprise Surveys, Inspections and Investigations

We have recognized the below seven vital steps to conduct the evaluation and condition monitoring of CP system:

Pre-assessment study
Preparation of methodology and processes
Technical audit of existing cp system, installation of main pipelines and performance assessment of tank form area, pump stations facilities and connected piping network
On/off potential survey, Close Interval Potential (CIP) survey and line current survey
Visual inspection of heat shrinkable sleeves
Analysis and assessment of remote monitoring and control system
Post assessment of the project – final reports and deliverables
