Asset Security

We develop detailed engineering solutions for the neutralization of stray currents. Once interference is identified, we design and install technical grounding systems that eliminate the risk of accelerated corrosion in your assets.

Description

Proven Experience: Engineering of turnkey solutions in accordance with NACE SP0169 for the control of direct current discharges in underground infrastructure.

Service Description

When field diagnostics confirm the presence of DC interference, implementing a robust solution is non-negotiable. TECNA ICE’s DC Interference Mitigation System Design integrates multivariate analysis of the source (mines, meters, third-party rectifiers) with the electrical response of your asset. We don’t stop at theory: we carry out the detailed design and subsequent installation of galvanic or forced drainage systems, ensuring that the interference is returned to its source without damaging the steel or the lining of your pipeline.

Scope of Engineering

Modeling of interference flows.
Design of specific anode drainage beds.
Selection of reverse current blocking devices.
Design Calculations for Forced Drainage Systems.

Installation and Warranty

Execution of civil engineering and electrical work.
Installation of control and monitoring stations.
Commissioning tests and current balancing.
Technical documentation and final engineering drawings.

Methodology and Traceability

Our “Design-Build” methodology guarantees complete traceability. We begin with an engineering phase in which we identify critical discharge points using potential maps. Subsequently, the design is translated into a physical installation supervised by certified engineers, who verify in real time that the mitigation system neutralizes the interference without affecting the polarization of the primary cathodic protection system. This comprehensive approach drastically reduces the time between the identification of a risk and its permanent elimination.
