The project developed by KT Italy  by means of EPC-LS modality has relied on GRIRO SA (2) for the supply and manufacturing of a package of 14 items (13 process columns, and 1 incinerator). (3)

CADE, which has developed the complete mechanical design of the equipment, has participated in the project as design engineering supplier (GRIRO SA). CADE’s scope of works has included mechanical calculation and design, finite element analysis of critical parts, manufacturing drawings and as-built review, based on the prescriptions of codes GOST 34347-2017 and ASME VIII Div. 1 & 2, as well as the LUKOIL / KT‘s own specifications for the project.

The project has been a great challenge for CADE, both due to the volume of work, the great coordination required between the different parties involved in the project, and the difficulties derived from updating to a new version of the local design code (GOST), once the project had started.

Our thanks to KT Italy and especially GRIRO for the trust placed in CADE and the unconditional collaboration of all parties to complete the project successfully.
