Download Flyer

" Elsyca CatPro is the easiest-to-use modeling and simulation software for the design and maintenance of cathodic protection systems of buried pipelines. Moreover, the prompt and professional support of Elsyca has made this an extremely satisfying solution "

Accuracy at the fingertips

Easily define your exact configuration by relying on:

Geographical coordinates
Actual routing
Field input data (local coating quality, soil resistivity, and polarization data along with the pipeline routing)

Flexible scenarios

Local (100 km range) study of the impact of changes affecting CP DC interferences for:

Multiple pipelines – parallel and/or crossing with separate CP systems;
Congested environments with hard-surfacing and complex geometries;
Cost-efficient determination of “IR-free” for pipelines or systems;
DC traction or HVDC interference;
Locations where CP systems can adversely affect the power-line or power system grounding/earthing.
