ADGAS Plant facilities at Das Island were not provided with lightning protection system with a view that UAE experiences very few rainy days every year. Traditionally, lightning strikes were not a major concern for LNG facilities on Das Island. With the ageing plant and the changing environmental conditions, the LNG Plant has been experiencing fire situations near Boilers, fuel gas, lube oil and other process vent points during thunderstorm days.

A study was conducted to identify the potential risk areas and propose the most appropriate solution based on the latest IEC standard and industry practices.

A risk assessment process was carried out for all the existing plant facilities to identify which specific structures/equipment were at risk and hence were required to be provided with lightning protection system, the steps taken to mitigate and eliminate these risks identified, and the challenges in completing and implementing these installations in a running LNG plant evaluated.

A novel technology was implemented for the Paraffinic Naphtha Tanks to eliminate the risk of fire from lightning, where an RGA protection system was implemented in place of the more traditionally used catenary lightning protection system.

For most of the structures use of existing structures as down conductors for lightning protection was explored and implemented which lowered the implementation cost and significantly reduced the installation time.
