Gas turbines, GG and Compressors systems

Instrumentation, ESD, Process Control and Automation systems

Contel proposes a turnkey project for Electrical, Instrumentation, ESD (Emergency Shut Down), Process Control and Automation systems for Gas turbines, GG and Compressors systems. The Company has specific expertise in this area, and a proven track record in the complex upgrading of systems with minimum production downtime.

Contel proposes a comprehensive upgrade for all the components of the gas turbine control systems including detailed design, manufacture of the Control and Instrumentation Panels, Field wiring work, on-site installation of the Panels and field instrumentation, the PLCs, Control Valves, and protection systems for the rotating equipment.

In its projects, Contel uses leading-edge technologies from Rockwell Automation and several series of controllers from Allen-Bradley.

Contel has extensive experience in carrying out upgrades in a volatile environment using the most advanced protective measures in the world. Combining vibration monitoring solutions with advanced control systems is the key to the success of the upgrade projects that Contel offers its customers.

Upgrades of control systems are based on PLCs from the ControlLogix flagship series, enabling implementation of full redundancy for all the system’s components.

The protection systems supplied by Contel include use of the Entek product series acquired by Allen Bradley, and use of existing sensors from Bently Nevada or installation of new sensors. The protection systems for rotating equipment enable not only emergency stopping, but also prediction of turbine performance, hence reducing down time resulting from maintenance actions that are not necessarily immediate, and increasing production output.

The software systems and the HMI supplied by Contel come from the Rockwell Automation Factory Talk View series.

Contel’s scope of works consists primarily of products and services that fit Contel’s core business and expertise.

d. Contel reference list includes wide range of activities, including complete turnkey project for upgrading Gas Turbine, Gas generator Turbine compress system, including all the above mentioned activities and products.

e. Contel is the sole distributor and authorized Rockwell Automation, Allen Bradley in the territory of Israel, since 1966 as well as Dresser Masoneilan, for Control Valve for Oil and Gas Industry. Dresser is global leader company in the Oil and Gas Industries

f. Contel is Panel manufacturer and works under the ISO 2001/9000 standard, our manufacturing plant manufacturing during 2009 about 1,000 control PLC small panels for Thermo-Solar power station and running the turnkey for this project including Fiber-Optic cables connection works, servers and complete control room.

Contel upgraded the control systems for main compressors and control and instrumentation equipment at Luginetsk Gas Compression Station, OAO “Tomskneft” as a subcontractor to OOO “Intek”. Contel did the works in very short time and with minimum downtime.

The challenge was to upgrade the systems with minimum interference to the station works. Contel upgrade the first system while on the same time the second station remain running. The first system shut down was for 3 weeks. After a successful commissioning – the second system was shut down for its upgrading for the same time.

In this project – Contel scoop of works includes the following:

1. Detail design of the control system including the design of new control panels and design of cabling connection works

2. Panel manufacturing including supply of Allen Bradley ControlLogix control system

3. Automation software implementation works

4. Local operator panel software implementation works

5. HMI software implementation works including dynamic operator viewers , Trends, Reports and alarming system.

6. Simulation works including running of control panels with operators panels, HMI and Automation software with Tomskneft station engineers on Contel premises

7. Onsite installation and cable connection works

8. Loop Test and commissioning

9. Final tuning and balancing works
