A unique suspended slab-support system was designed for this project.  A travelling gantry was designed to meet the unique time and labour requirements for this project.

12 concrete underground tanks are currently being built, each of which is 110 by 110 meters, as large as two football fields. A total of 13.2 million barrels of oil can be stored here after completion. 150,000 cubic meters of concrete total - equivalent to the contents of more than 60 Olympic swimming pools. PERI was extensively involved from early design stages up to completion. The OTMS tank structures called for a unique design to construct the columns, walls and slabs. Sloping slabs on top of 17 columns, as well as the sloping floors presented design challenges for the design of a suspended support system for the slabs
