Corrosion Simulation Newsletter
The design verification of CP systems applied to underground facilities including storage tanks, buried piping, equipment bases, grounding systems, reinforced concrete and other underground structures is complex challenge. Space limitations may restrict installation of anodes in certain areas and shielding effects from buried structures may affect the distribution of the protective current. Modelling provides a tool to ensure adequate protection by evaluating ground bed design options and locations to mitigate the effect of interference and shielding.
A recent study investigated the impact of interference between nearby storage tanks and pipelines on the performance of the CP system and the potentials achieved.
The modelling study aimed to verify the protection provided including the interference between the CP systems for the underground infrastructure comprising three tank bases, pipelines with different quality coatings, ICCP Anodes, grounding rods, tank bottom ICCP Grid and sacrificial anodes.
BEASY attended the recent NACE Corrosion Conference in Orlando where we made contributions to the conference program, technical meetings and exhibition hall, showing our corrosion modelling services and software.
We highlight two presentations on the benefits of modelling for corrosion control in structures and ballast tanks.
