COMECA was recently requested by the Office Chérifien de Phosphate « OCP» factory for the retrofit of TRA Low Voltage switchboards. The aim is on the one hand a progressive equipment replacement with no modification, and on the other hand the compliance of switchboards with the IEC 61 439-2 standard.
The OCP is the world’s leading producer of phosphate rock and phosphoric acid as well as one of the leading global fertilizer players. Further to an on-site audit carried out by COMECA’s technicians, an analysis demonstrated the equipment’s and components’ level of obsolescence, installed in the factory’s electrical stations since the beginning of the 80’.
COMECA’s experts reported a list of articles to replace as well as the actions to implement to ensure switchboards’ compliance with the IEC 61 439-2 standard, applicable since 2011.
In addition to standards compliance, the customer’s goal is to minimize downtime during intervention, since the factory normally operates continuously, on 24 hour/7 day basis. Besides, the client wishes to keep the location of all equipment, in order to avoid any cable modification.
Taking into consideration operating constraints (operation time, equipment’s adaptability) and costs constraints, COMECA recommended a solution of progressive renovation adapted to customer’s budget.
