BTC Expansion Project

Project Description

The BTC Expansion Project comprised modifications at PSA-2 facilities in Azerbaijan. The works included construction of concrete bases for the DRA equipment and shelter, construction of the shelter itself, hook-up of the DRA equipment and subsequent pre-commissioning and commissioning of system. The engineering disciplines involved in the project included civil, structural, piping, mechanical, electrical, instrumentation and telecommunications works. Furthermore, Encotec participated in Hand-over and Start up activities.
