Description
Diagnosis for Redesign: Rehabilitation isn’t just about repairs; it’s about understanding why the original system failed. At TECNA ICE, we gather technical evidence in the field to design lasting solutions.
Service Description
TECNA ICE’s Cathodic Protection Systems (CPS) Rehabilitation service is designed for infrastructure that no longer meets the protection criteria established by NACE/AMPP standards. This service is critical when rectifiers have reached their capacity limit, anodes have been consumed, or the coating has suffered significant degradation. Our process begins with a multi-technology field survey, during which we evaluate potential profiles, leakage currents, and the resistance of existing anode beds. This data serves as the primary input for developing a new engineering design that enables the implementation of an efficient system—whether using impressed current or sacrificial anodes—ensuring the asset’s full integrity for a new operational cycle.
Field Survey
- Detailed inspection of existing components.
- Transient current injection tests.
- Analysis of Current Demand.
- Assessment of third-party interference.
Engineering Results
- Design of new anode beds (shallow/deep).
- Specifications for State-of-the-Art Rectifiers.
- Localized Corrosion Mitigation Plans.
- Quantity Surveys and Construction Estimates.
Technical Management
TECNA ICE approaches retrofitting as an optimization challenge. Often, it is not necessary to replace the entire system, but rather to identify the electrical “bottlenecks” that prevent polarization. Our expert team analyzes the interaction between the ground, the aged coating, and the current demand, delivering a rehabilitation design that minimizes implementation costs and maximizes protection coverage. We ensure that the transition from the old system to the rehabilitated one is seamless and complies with all industrial and environmental safety requirements.
When Is Rehabilitation Necessary?
Exhaustion
The current anodes have reached the end of their design life.
Underprotection
The structure-to-ground potentials are out of specification.
Inefficiency
High energy consumption for low polarization levels.
Obsolescence
Old equipment without monitoring or adjustment capabilities.
