Control and safety systems for industry, from design to support.
Stratum Engineering designs, builds, tests and commissions industrial control systems for refineries, power plants, pipelines and process industries. We are a joint venture of Smartsys and Oskar-El: two engineering companies, one team.

What we do
Our services cover every layer of an industrial control system: the design, the hardware, the software, the site work and the years of support that follow.
Control and safety system design
DCS and SCADA systems based on Honeywell, Siemens, Schneider Electric and Westinghouse platforms.
Read moreSystems integration and control rooms
Plant information systems and central control rooms that bring separate systems into one operating picture.
Read morePanel manufacturing and FAT
Low-voltage electrical and automation panels built and tested in our own factory near Sofia.
Read moreMigration, upgrades and lifecycle support
Control system migration and optimization for Honeywell, Westinghouse, Siemens and Schneider Electric systems.

Our products
Software we build ourselves for control system engineering and operations. More products will be added here.
From first drawing to long-term support
Every project follows the same seven stages. We can take part in all of them or join at the stage where you need us.
Conceptual design
We work with your team to set basic system requirements, control objectives and strategies, interlock and safety considerations, and the standards for hardware, programming, HMI, alarm management and testing.
Detail design
Hardware, software and HMI are designed to the agreed concept: architecture, I/O, cabinets, cabling, control logic, graphics and alarms, documented and reviewed with you.
Manufacturing
Panels and cabinets are built in our own factory near Sofia, with wire processing, laser cutting and testing equipment on the same site.
Factory acceptance test
The complete system is tested in our dedicated FAT area before it ships, so problems are found in our hall, not on your site.
Commissioning
Our engineers install, check out and start up the system on site and hand it over to your operations team.
Maintenance and support
Support and maintenance, on site and remote, for the whole life of the system.
Optimization
Tuning, upgrades and migration to current technology as the plant and its needs change.
Industries we work in
