Thank you for your interest in our company! Founded as a small commissioning company, today COTES is one of the leading Russian engineering groups in the power industry. We have combined long-term experience in mastering the largest domestic thermal power plants and designing large modern power units based on  state-of-the-art equipment, using high-efficiency, environmentally friendly solutions and high- performance technologies for the combustion of different fuels. In close cooperation with one of the key manufacturers of power- generating equipment — the Machine Building Factory of Podolsk, as well as industry research institutes and academic institutions, COTES has competences to promptly and effectively investigate and apply both manufacturers’ and in-house engineering innovations which contribute to the reliability, environmental performance and cost efficiency of modern power plants. The wisdom and experience of the older generation combined with the energy and ambition of young engineers ensures the constant development and, hence, the  future of COTES. And I believe that, for many years to come, our fair partners and new customers will gratefully note our high skills, effectiveness and the engineering level of all the services provided by our team.

Innovations The company logo is a new design coal-fired boiler with a circular furnace developed for large power units by the team of engineers under leadership of Feliks Serant, Adviser for New Technologies in COTES. In April 2015, at InterRAO Scientific and Technical Council the boiler design was recommended for consideration to all coal-fired power plants under construction and upgrade. The circular furnace enables our clients to: Reduce boiler height (by 30-40%); Ensure slag-free cost efficient combustion of decker coals; Reduce NOx emissions through more intensive mixture formation and in-furnace gas circulation; Facilitate design of boiler building and supporting structures through the installation of a large central pylon inside the inner shaft.

Cutting Edge IT-solutions To implement all engineering activities — from design to commissioning— COTES applies the most up-to-date internationally recognized software and equipment. Software for 3D PDMS by AVEVA allows us to dramatically cut the time needed for drawing development, calculations, and enhance documentation quality avoiding errors and collisions. In 2015, COTES representative took the first prize in AVEVA MAGISTER competition. The competitions is aimed to find the most advanced user of the software. E3.Series allows us to decrease period required for development and issue of drawing packages for electric and automation; it ensures possibility for user groups to work simultaneously on a real-time basis. ElectriCS 3D is used for automated (automatic and interactive) routing the cables of different types during design, rehabilitation and maintenance of buildings, structures, and open areas. Software for project management enables management of design activities, online control and monitoring of business processes, and creating of project reporting system.

Commissioning Equipment COTES possesses a complete fleet of the required equipment and measuring tools for equipment testing and instrument inspection: pressure transmitters; pressure difference transmitters; resistance temperature detectors; gas analyzers, micropressure gauges, pyrometers, temperature transducers, etc. A special measuring system (mibile DCS) for thermal testing of equipment was designed and constructed upon our request; using this system the engineers are able to monitor and record over 130 parameters every second.
