TELEMECHANIZATION AND CONTROL OF THE MAIN OIL PIPELINES

TO TM MN carries out functions

alarm systems:

− states and provisions of shutoff valves;

− passings of means of cleaning and diagnostics (SOD);

− accidents and malfunctions of the drive of shutoff valves;

− states and provisions of linear disconnectors and switches along the route high voltage line;

− presence of tension along the route high voltage line;

− the minimum and maximum temperature in points of control and management (PKU);

− a maximum level in the capacity of collecting leakages of the SOD check point;

− floodings of wells of selection of pressure on transitions of MN through water barriers;

− floodings of the platform of the start-up reception chamber (SURC) of SOD on transitions of MN through water barriers;

− existence of leaks at the SOD check point;

− conditions of the security alarm system (PKU, wells of selection of pressure);

− condition of the PKU fire alarm system;

− the perimetralno-security alarm system of the SOD check point on MN software;

− the security alarm system of the plungers located within knot of linear

latches;

managements:

− linear locking equipment;

− equipment of control of passing of SOD (team of control and unblocking);

− security alarm system (giving of team of unblocking of security

alarm systems);

− disconnectors and switches along the route high voltage line;

− security lighting;

measurements:

− the current pressure in MN;

− an oil consumption on MN;

− the current pressure in the disconnected reserve threads on underwater transitions;

− the current pressure on chambers of the admission, start-up, reception of SOD located out of the NPS platforms;

− current of the station of cathodic protection (SCP);

− SKZ tension;

− protective potential "pipe earth";

− potential in UKZ drainage point;

teleregulations:

− provisions of executive mechanisms of systems of regulation on linear

parts;

− output tension (current, protective potential) ECP stations;

communications:

− for the information transfer necessary for work of system of detection of leaks;

− for exchange of information with the information systems located in

operator various dispatching levels.
