During manufacturing phase of BAOT project and considering high emissivity index in hot months of the
year in the south of Iran and consequently unbalanced expansion and shrinkage of the floor, 3 from 31
tanks of Bandar Abbas Oil Terminal project have faced with movement on foundation and get out of the
orientation from Southeast to Northwest.
These 3 tanks had a 40k m3 capacity and 20m height.
Although this movement was occurred out of our control, STEAM experienced engineers decided to re-
allocate the tanks by Jack Lifting method.
In this method, they used 6 Horizontal Enerpac jacks with a 100mt capacity which transferred the forces
to tank body through 6 steel elements and by using concrete ring wall as support. Also, they put some
pipes under annular plates for reducing friction between tank floor and foundation.
The movement based on the above method has been done successfully during 4-5 days for each tank by
setting 300bar pressure on each Jack.
