Corrosion is one of the most costly threats to pipeline infrastructure, storage vessels, and structural steel in the oil and gas industry. TafDav Technical Services provides complete Cathodic Protection (CP) Engineering, Procurement, and Installation (EPI) services — protecting your assets from corrosion damage and significantly extending their operational life.
Cathodic protection is an electrochemical technique that controls corrosion by making the metallic structure the cathode of an electrochemical cell. TafDav has expertise in both Galvanic (Sacrificial Anode) and Impressed Current Cathodic Protection (ICCP) systems, selecting the most appropriate solution based on your asset type, environment, and operating conditions.
TafDav's CP service follows a structured EPI process: we begin with a detailed corrosion assessment and soil/water resistivity survey to characterize the environment. Our engineers then design the optimal CP system — ICCP or sacrificial anode — sized for the asset's design life. Procurement is managed through our international network to source certified anodes, rectifiers, reference electrodes, and monitoring equipment. Installation is executed by trained field teams, followed by commissioning testing and a comprehensive baseline CP survey. We also offer long-term CP monitoring and maintenance programs to ensure continued system effectiveness.
A: Sacrificial (galvanic) anode systems use more active metals (zinc, aluminum, or magnesium) that corrode preferentially, protecting the structure without any external power. ICCP systems use an external DC power source (rectifier) to drive current from inert anodes to the structure. ICCP is typically preferred for long pipelines or structures in highly resistive environments, while sacrificial anodes are simpler and suitable for smaller or isolated structures.
A: TafDav conducts soil resistivity surveys, pipe-to-soil potential measurements, and corrosion risk assessments to determine the corrosivity of the environment and the current condition of the pipeline coating and metal. These data points inform the CP system design.
A: Yes. TafDav has experience retrofitting cathodic protection on existing buried, aboveground, and subsea pipelines. We assess the current CP status, identify gaps in protection, and design appropriate retrofit solutions including new groundbeds, additional anodes, and upgraded monitoring systems.
