Real Mitigation

We design, build, and commission solutions for controlling electromagnetic interference. We ensure that your infrastructure complies with safe voltage limits through robust and technically validated installations.

Description

Proven Experience: Execution of turnkey (EPC) projects for mitigating risks associated with AC induction in oil pipelines, gas pipelines, and water transportation systems.

Service Description

When electromagnetic interference exceeding safety thresholds is identified (such as 15 V AC under normal conditions according to NACE SP0177), it is imperative to implement mitigation systems. TECNA ICE’s AC Mitigation System Installation and Commissioning service ranges from engineering design based on modeling to the physical construction of grounding networks and the installation of decoupling devices. Our goal is to dissipate induced currents in a controlled manner, protecting both the integrity of the steel and the safety of operators.

Scope of Installation

Construction of potential gradients and grounding systems.
Installation of solid-state devices (PCR/SSD).
Assembly of AC corrosion monitoring coupons.
Technical Interconnection of Mitigation Systems with Pipelines.

Commissioning

Earth continuity and resistance tests.
Post-installation validation of step and contact voltages.
Verification of the effective depolarization of the duct.
Submission of construction files and as-built drawings.

Methodology and Traceability

At TECNA ICE, installation follows a rigorous protocol: we start with the engineering design to determine the optimal location of the drainage points. During construction, we ensure low contact resistance of the electrodes and the correct configuration of the decoupling devices so that they block DC current (while preserving cathodic protection) and drain AC current. Commissioning concludes with field measurements that confirm the reduction of risk to acceptable levels, delivering a fully operational and traceable system.
