LNG Storage Tanks

The field erection of 2x140.000 cum LNG Storage Tanks, capacity wise the second largest in the world as of 2001, for EGEGAZ LNG Terminal located at Aliaga-Izmir, Turkey, successfully completed within 18 months. The LNG Storage Tanks are designed by CBI as per API 620 and have a total steel weight of 6.000 tons, the inner tank steel material being ASTM A553 Type 1 requiring advanced welding technology. The very unique feature of the project is the lifting operation of the tank roofs. Following the ground assembly, the tank roof with a single piece weight of 800 tons and a diameter of 80 m has been lifted to its final position at +35m by means of compressed air blowing.
