GreyMatters was tasked with providing an earthing design for a refrigerated ethylene tank in Ruwais, UAE, ensuring compliance with stringent safety standards in the petrochemical industry. This project highlights their expertise in lightning protection and earthing, addressing the unique challenges posed by the region’s geology.
The petrochemical industry is particularly vulnerable to lightning-induced ignition due to the large-scale processing and storage of flammable substances. This creates hazardous volumes classified by ATEX, requiring both a sufficient rooftop air termination system and an appropriate route for lightning current to earth. GreyMatters combines lightning protection compliance with extensive earthing expertise to address these challenges effectively.
GreyMatters was tasked with providing the LV earthing design for a refrigerated ethylene tank in Ruwais, UAE, ensuring compliance with a maximum 4 Ohm earth impedance requirement and BS EN 62305 standards. They facilitated a smooth design transition by supplying single-hole earth terminals on the tank roof, connected to the tank reinforcement lattice as a down conductor. This setup ensured easy connection from the eventual air termination system to earth.
