This work had been performed by OAO TATNEFT and OOO “Neftegasengineering” with good quality and on time.

Two Mammoet cranes of 1,350 tons and 500 tons capacity as well as specialized auxiliary machinery were used for assembling the heavy equipment. The equipment lifting was carried out by experts of Mammoet and Unix companies, which both had approved themselves in carrying out lifting operations and mechanical mounting works.

The complexity of the operation was that the vessels had to be mounted inside the existing metal structures of the amine treatment block for hydrogen containing gas and the technological rack of the gas compressing battery. After thorough verification of the structures installation correctness they were fixed in the design positions.

Lifting of the heavy equipment under the project of works performance developed by experts of mounting organizations and the Department of implementing the construction project of the combined hydrocracking installation of OAO TATNEFT were performed in a regular mode.
