Risk Based Inspection (RBI) of Aboveground Storage Tanks to Improve Asset Integrity

Kuwait Oil Company (KOC) has 85 crude oil aboveground storage tanks in its Tankfarms for the storage of crude oil prior to export. These tanks have storage capacities ranging from 162,000 to 597,500 bbl. (US). Hydrocarbons leaks / spillages resulting from tank failures, if any, could be very expensive and could pose serious fire hazards apart from major environmental issues. Therefore, in order to carry out a comprehensive assessment of the tanks to prevent any impending failure, KOC decided to adopt Risk Based Inspection (RBI) approach to evaluate the risks associated.
