The article describes the asset and risk management approach of a primary electrical company in the Middle East area. A specific maintenance strategy has been carried out for loss prevention of giant transformers, addressing mainly the corrosive sulfur. Starting from the international standards and considering the specific context, the appointed consultancy company GCC Lab selected the most efficient long-term mitigation technique: the selective depolarization.
This process, developed and operated by Sea Marconi, is proven to be effective in the removal of DBDS and oil corrosive compounds, even after one year, also restoring all chemical and physical properties of the oil.
