PFS “Surgil field complex costruction with valuable
components retrieval”
It is provided by the project following types of lightning: exterior lighting of
territory, interior - working, emergency and repair lightning. Lamps voltage ~220V, repair
~36V.
Exterior lighting is provided to execute by lamps RKU-01-250 with mercury lamps
DRL-250 installed on ferroconcrete support at height of 8m.
Lighting of technological areas is executed by searchlights PZS-45 with glow lamps,
installed on searchlight towers at height of 22m. Local lighting of technological areas is
executed by explosion-proof lamps with glow lamps, installed on the fence railings and on
the floorstanders.
It is provided control box in the control post for remote control of exterior lighting.
The control of lamps in premises is carried out by switches in a place.
It is provided by the project following actions of electrical safety:
- electrical equipment earthing at all steps of voltage according to PUE
requirements;
- lightning protection, earthing, explosive zones protection protection
according to RD 34.21.122-87;
- choice of electrical equipment and electric wirings according to the
environment.
This project of Surgil GCF construction for gas production of 3 billion cubic m per
year provides electrochemical protection of the following constructions:
- 54 wells, loops by diameter of 108х6mm, by length of 108km;
- equipment of GGS -1. GGS -2. GGS -3 areas;
- gas reservoir of GGS -1 - CGTU, GGS -2 - CGTU, GGS -3 - CGTU, by
diameter of 273х9mm, by total length of 11.4km;
- equipment of CGTUarea;
- Surgil CGTU– Akchalak GCC gas pipeline by diameter of 820х9mm, by
length of 115km;
- Surgil CGTU– Akchalak GCC condensate line by diameter of 168х6mm, by
length of 115km.
The connection scheme of electrochemical protection provides joint and separate
protection. Electrochemical protection is carried out by installation of the switchgears of
cathodic protection UKZV, UKZN type and subsurface anode earthing devices from steel
pipes by diameter of 219х8mm, by length of 75 and 100 meters.
Power supply of buildings and constructions of the camp is provided from the enblock
diesel generator on gas fuel.
Design capacity makes 290kV.
