O&G Industries teamed with Chicago Bridge and Iron to construct this concrete-walled liquefied natural gas storage tank project. O&G was responsible for the $23 Million civil/structural portion of the contract. Among the many challenges was construction of the tank's concrete walls which are post-tensioned.
The walls were poured in ten-foot lifts. Four pours used single-sided circular wall forms that weighed nearly 32 tons and that necessitated the services of a fork lift, three cranes and five different crews. The tank is 130 feet tall, 158 feet in diameter and holds 14.6 million gallons of liquefied natural gas.
Other components of the project include four support buildings ranging in size from 3,000 to 9,000 SF for operations and maintenance and 3,500 linear feet of site utilities. Only a handful of similar structures exist around the world in places like Barbados, Nigeria, the north of England, Russia and the United Arab Emirates, but this is the first facility of its kind in North America.
