Maintenance of Gas Networks<br />

The reliability, safety and efficiency of the gas networks are secured by a system for<br />

their technical maintenance and repairs. This system has two major aspects:<br />

а) Maintenance and repair organization including:<br />

maintenance structure (territorial location of the repairoperational facilities, number and qualification of the repair staff);<br />

typization, sequence and matching of works;<br />

logistics;<br />

b) Current maintenance management including:<br />

technical condition control, planning of schedule and volume of works;<br />

organizational-technical management of staff and technical repair<br />

equipment.<br />

In the course of the system operation the necessary measures are undertaken to run<br />

preventive maintenance on industrial consumers’ days-off or in certain consumers’<br />

off-peak periods. In this manner the faulty element of the system can be switched off<br />

without affecting the consumer. This aims to restore and maintain the pre-set<br />

reliability level through a relevant analysis of the reliability of the individual system<br />

elements and scheduled check-ups and repairs.
