An integral part of the production and technological process are highly focused special activities known as commissioning. In the process of carrying out these activities, the equipment is checked for failure-free operation and safety, the possibility of putting it into operation and bringing it to its design parameters. First of all, the documentation of the project to be verified is reviewed. Equipment is checked and tested in case of possible failures and emergency situations. In addition, this also includes a lot of additional work performed in the process of preparing and conducting individual tests of the entire equipment complex.
The procedure for commissioning work
Performance commissioning works carried out after the equipment has been installed. The main objective of these activities is to comprehensively test the installations being tested. During the inspection, the degree of their safety and reliability and compliance with the declared design characteristics are determined. Based on the results of the work, all identified deficiencies that impede the normal operation of the equipment are eliminated.
Installation and commissioning work is carried out by specialized organizations with which the enterprise enters into a business agreement. If the enterprise has trained engineering and technical personnel and the necessary control and measuring instruments, then these works can be performed on our own. These workers belong to the category of operational personnel. They must complete a training course. After passing the exam, a protocol is drawn up and a certificate is issued for the right to perform commissioning work. For workers, repeated knowledge testing is carried out annually, and for engineering and technical workers - once every 3 years.
Commissioning work ends with the preparation of a technical report, reflecting all the stages completed, with conclusions and recommendations for further improvement of the operation of equipment and installations. Thus, this report is the main document characterizing the volume and effectiveness of the work performed. Practical experience shows that the cost of commissioning and commissioning activities pays off already in the first months of operation. For example, the results of calculations and comparative tests show that due to proper start-up and adjustment, fuel savings can be 3-5%.
To carry out commissioning work, a team of specialists is involved, who must be supervised by a qualified engineer. The number of workers is determined in accordance with the volume of work to be done, usually no more than 5 people. The main activities are carried out by engineering and technical workers, and enterprise personnel are used for auxiliary work.
For each type of equipment, a commissioning program is drawn up, agreed with the management of the enterprise. During its development, the main attention is paid to practical experiments, during which individual components are tested, design flaws are identified, and the quality of installation is determined. Great importance is attached to experiments to verify the reliability of operation of all types of equipment and its ability to maintain specified parameters. The maximum value of the unit’s performance and the stability of its operation at low loads are determined.
Such checks are carried out in sufficient quantities to draw up an approximate regime map, which takes into account the entire range of operational loads. To determine some parameters, instrumentation of the equipment itself is used.
At the end, the most important activity is carried out to comprehensively test the equipment and put it into operation. This operation is carried out only with the permission of the adjuster group leader. No one should interfere with his orders, except in cases where a threat arises safe work equipment and maintenance personnel.
Electrical commissioning works
Commissioning work is carried out at the final stage of electrical installation work. During this period, electrical equipment is tested and checked for compliance with the design, current PUE, technical specifications and documentation of the manufacturer. All units must comply with the declared technological indicators. After all settings, testing and testing have been carried out, conclusions are issued on the performance of the entire installation and each of its components.
Our organization in a short time and with high quality will fulfill wide range such work, including commissioning of the electrical equipment system. The company’s specialists will carry out activities in several stages:
- Obtaining from the customer and carefully studying the technical characteristics of the installations, technical documentation and the electrical part of the project, its relationship with technological processes.
- Preparation work program and the project for commissioning work, including activities related to safety, their coordination with the customer.
- Analyzing finished documentation, identifying shortcomings and other comments.
- Preparation of instructions, technological maps and guidelines on adjustment issues. Particular importance is attached to protocols and other forms of reporting documentation, preparation necessary tools, instruments and accessories.
After the preparatory period, execution commissioning activities carried out jointly with . A timing circuit is used to supply voltage to the equipment. When combining work Special attention calls for compliance with safety regulations. By this time, all construction work, heating, lighting and ventilation in the rooms with electrical equipment have been completed. The electrical equipment itself is already installed and grounded. Wells, openings and cable channels were closed.
At this stage, the installed electrical equipment is tested by applying voltage through test circuits to individual devices. When performing this operation, electrical installation personnel should not be in the adjustment area. If defects in electrical equipment are identified, they are eliminated by the customer, and installation errors and shortcomings are eliminated by the electrical installation organization. Based on the results of the second stage, the company’s employees draw up the following documents:
- Protocol of tests and measurements of insulation.
- Protocol.
- Protocol for setting up protection and relay contactor equipment.
- Executive diagrams of objects subject to power supply, connected to voltage.
At the next stage, individual tests of electrical equipment are carried out, in which voltage is supplied according to the normal operating circuit. First of all, for electrical installations, input is carried out operating mode and registration of personnel permits in accordance with safety regulations. After this, the adjusters adjust the equipment parameters, test the protection, control and alarm circuits. Before testing process equipment, it is necessary to set up and check the operation of electrical equipment at idle speed.
After the company’s specialists conduct individual tests, the electrical equipment will be considered accepted for operation. Based on the test results, all necessary documents will be drawn up and handed over to the customer:
- Protocols for testing grounding and grounding.
- Test reports for electrical equipment at elevated voltage.
- Basic executive diagrams, as in the previous stage.
The remaining documentation is provided to the customer within two months after the equipment is put into operation. For objects of increased technical complexity, this period increases to four months. At the end of this stage, a technical readiness report is drawn up for comprehensive testing of electrical equipment.
Comprehensive testing is carried out according to special programs agreed with the customer. During this event, the interaction of electrical equipment systems and electrical diagrams in various operating modes. Parameters in individual devices and functional groups are regulated and configured, their mutual connections are ensured, and specified operating modes are created. Electrical installations are tested according to a complete scheme, which makes it possible to prepare and conduct comprehensive testing technological equipment.
Commissioning of equipment
In order to put the installed technological equipment into operation, it is necessary to carry out commissioning work. The volume of these activities can be up to 20% of the entire project. These works are carried out at the final stage, before putting the equipment into operation.
In our organization, we efficiently and quickly carry out commissioning work on all major types of equipment. The company’s specialists will competently carry out the following activities:
- They will check the compliance of the design documentation with the actual execution.
- They will prepare and test production lines.
- Perform inspection, testing and calibration of various instruments and automation.
- They will test individual components and assemblies, auxiliary systems, and run-in dynamic equipment.
- Organize activities for comprehensive testing of the facility and its commissioning.
- They will train personnel for subsequent operation of the equipment.
As a rule, the organization of commissioning work at any facility is carried out at the last stage of construction and installation work. Already during this period, engineers discover possible inconsistencies between the design documentation and the installed equipment. Because of this, malfunctions may occur in the future, so it is very important to eliminate all shortcomings in a timely manner. This stage is of great importance and guarantees reliable operation of the facility in the future.
Our commissioning organization offers a full range of services, from setting up individual technological elements to complex facilities in various industries.

Commissioning work is a series of activities to prepare equipment for launch, check assembly according to factory diagrams and trial testing the functioning of all systems. Experts have developed a specific scheme of actions for testing the technological complex, which is summarized by the term « commissioning methodology ».
All work is carried out strictly in accordance with the project plan of the facility. One of the important points at the commissioning stage is to check the main equipment systems under above-average load conditions and their response to critical conditions. Successful commissioning indicates continued production efficiency and safe operation equipment.
List of commissioning works
Important points in the commissioning methodology are the following requirements:
- All specialists and commission leaders involved in commissioning work must be highly qualified, trained and pre-certified to test their knowledge in the relevant field of technology;
- Commissioning works begin only AFTER the issuance of a permit, issued in accordance with the legislation of the Russian Federation, to start work;
- All measuring instruments and materials used must be tested;
- Equipment adjustment starts after the equipment acceptance certificate is signed by members of the working commission, taking into account the schedule and cost of the work;
It consists of 3 points:
Introductory part. Familiarization with the theory and available documents for the future installation and its location. It is necessary to study the features of the selected equipment model, technical data, etc. The Contractor creates a preliminary program of activities for commissioning.
Pre-practical part. Setting up equipment, regulating modes, checking communications, monitoring control, automation and alarm systems.
Individual testing. At this stage, each system is checked in isolation from others in order to avoid emergencies, leaks, breakdowns, etc. The necessary measurements, measurements, and coefficient calculations are made.
Commissioning First, in idle mode without producing finished products. If the test run is successful, the installation is further tested under load.
Drawing up a summary report on the work performed with testing results, defects detected and eliminated, and information on the functioning of the tested equipment.
When implementing many projects, capital construction or reconstruction of buildings and structures is carried out with the installation of new equipment or specialized processes. Such work includes the installation of fire extinguishing systems, electrical supply, air conditioning, ventilation, and fire alarm systems. All of them require commissioning work; for this purpose, commissioning programs have recently been increasingly drawn up.
What is PNR and why are they carried out?
According to SNiP, commissioning work is a set of activities that are carried out during the preparation of complex testing and individual tests installed equipment. This includes inspecting, testing and adjusting equipment to achieve design specifications.
All these manipulations are usually carried out on a contractual basis by specialized organizations that have the necessary permits and a staff of qualified specialists. The necessary conditions for their activities on the site (industrial sanitation, occupational safety) are organized by the customer, who also pays for the commissioning work at the expense of the general estimate for putting the facility into operation. All operations must be carried out by personnel of the commissioning organization, instructed and certified for each specific case, under the supervision of a responsible representative from the customer.
There are two main stages in commissioning activities:
- Individual tests are actions that are designed to ensure compliance with the requirements provided for by technical specifications, standards and working documentation for testing units, machines and mechanisms. The purpose of individual tests is to prepare for comprehensive testing in the presence of a working commission.
- Complex tests represent actions carried out after the acceptance of mechanisms by the working commission, and the complex testing itself. At the same time, the interconnected joint operation of all installed equipment is checked at idle, then under load, after which the technological mode envisaged by the project is reached.
Although this is not prescribed by law, in recent years the customer has increasingly required that a commissioning program be drawn up for testing work. This gives confidence that not a single nuance will be missed, and the operation of all systems will comply with approved standards and design documentation.
How is the commissioning program compiled and what does it include?
The commissioning program is a document that clearly describes the entire list of actions that will be carried out by the responsible organization. On the Internet you can see discussions about whether the commissioning methodology should be included in the Program or whether it should be drawn up as a separate document. There are no clear requirements regarding this, so it all depends on the agreements of the parties. A sample for each specific situation can be easily found on the Internet.
The program is drawn up and approved by a representative of the commissioning company and agreed upon by the customer; the signatures and seals of the parties are placed in the header of the document. Next are the following sections (as an example, let’s take the preparation of a hotel heating system):
- checking the correct installation, readiness and serviceability of equipment in visual mode (control devices, shut-off valves, filling the system with water), based on the results, a defective statement is drawn up;
- adjustment tests under operating conditions, balance experiments (installation optimal modes, testing valve control in manual and automatic mode, checking automation settings, identifying deficiencies and developing proposals for eliminating them), the result is an individual test report;
- comprehensive testing (72 hours of continuous operation for all major equipment, 24 hours for heating networks), its beginning is considered to be the time when all systems are started at maximum load.
Some companies document all activities directly related to the preparation and testing of devices in a separate document - the Commissioning Methodology, which comes as an addition to the Program. In the Program they include more general things of an organizational nature. That is, there is an actual division of the entire complex of work into organizational, legal and technical components. However, the Methodology is often an integral part of the main body of the approved Program.
The following additional documents may be part of the Program:
- passports of ventilation, heating and hot water supply systems, as well as individual components of their connection;
- the procedure for preparing and subsequently conducting commissioning operations with a list of all operations, their start and end times;
- list of stationary and portable measuring instruments (pressure gauges, thermometers, etc.);
- list of control and shut-off valves, equipment (pumps, valves, heat exchangers, filters);
- a list of control points and measurement protocol for each of them;
- a list of parameters that require clarification and adjustment (air humidity and temperature, pressure in pipes, coolant flow rates);
- methodology for measuring heat losses from building structures (a special report is drawn up and a certificate is issued).
After completion of all commissioning works, comprehensive testing and operational tests, a commissioning report is drawn up with the relevant appendices (a list of mechanisms and equipment on which adjustment and testing were carried out).
The technical report is usually issued by an involved specialized organization within one month.
