DISCOVERED IN 1979, TENGIZ IS ONE OF THE WORLD’S DEEPEST DEVELOPED SUPER GIANT OILFIELDS. THE FUTURE
GROWTH PROJECT (FGP), INTEGRATED WITH THE WELLHEAD PRESSURE MANAGEMENT PROJECT (WPMP), ARE EXE-
CUTED SIMULTANEOUSLY TO EXPAND TENGIZ PRODUCTION AND MAINTAIN FULL PRODUCTION RATES OF THE EXIST-
ING TENGIZ FACILITIES. THE FGP PLANTS WILL NOT PRODUCE SULFUR. THE NATURAL GAS CONTAINING HYDROGEN
SULPHIDE WILL BE RE-INJECTED INTO THE RESERVOIR TO MAINTAIN RESERVOIR PRESSURE. THE EXPANSION IS DE-
SIGNED AND CONSTRUCTED TO OPERATE WITH THE LATEST TECHNOLOGY TO REDUCE AIR EMISSIONS.

THE EQUIPMENT
Skema provided the following main
equipment for the 110 kV Core sub-
station:
> LV switchgear and MCCs com-
plete with auto-transfer scheme,
momentary synchronizing be-
tween incomers, switchgear and
transformer protection, control
and metering equipment
> Distribution boards, bus ducts,
distribution transformers and
PLC panel
> Electrical/instruments and F&G
systems
> HVAC system
> Hydrosanitary system
> Bridge crane
GE’s scope of supply included the fol-
lowing main equipment:
> 110 kV Gas Insulated Switchgear
(GIS) with associated protection,
control and metering equipment
> Utility metering for the 110 kV
interconnection with the Client’s
network
> UPS system and batteries
THE CORE SUBSTATION
The Core substation consists of 32
modules, which were prefabricated,
assembled, sand-blasted, painted
and bolted to form a unique structure.
After completion of the structural and
architectural assembly, the internal
equipment was installed and the sub-
station was tested.
The modules were then disassem-
bled and shipped to Kazakhstan.
The Core substation is built over 2 lev-
els, each divided into rooms. More in
detail, the ground floor includes:
110 kV GIS AREA – Steel struc-
ture made by assembled units which
contain the gas insulated switchgear
(GIS). A 1.5 t bridge crane is installed
over the top floor of the GIS area for
switchgear maintenance purposes.
ELECTRICAL ROOM – 2 transformers
feeding the LV switchgear, UPS, bat-
tery box, and the distribution boards
are installed in the electrical room on
the ground floor, which includes also
an office and a restroom.
BATTERY ROOM – Batteries are locat-
ed on specific racks in this room, which
is equipped with an eye wash facility
and a trolley to move the batteries.
The mezzanine floor hosts:
HVAC ROOM – The HVAC LV switch-
gear and PLC panel, the main air
conditioning equipment and the duct
system for the whole substation are
in the HVAC room, which includes
also 2 chemical filters and 2 fans.
INSTRUMENT EQUIPMENT ROOM
This room has been designed for
the control panels supplied by GE.
Access ladders, entrance, emer-
gency and maintenance service
doors complete the substation, and
5 removable panels ensure easy
instal lat ion and maintenance of
the bigger and heavier equipment.
A system of walkways at different
heights serve the electro/instru-
mental paths, starting from the low-
er part beneath the floor beams, all
through the intermediate section, up
to the upper part of the substation,
ensuring the connection among the
main equipment such as GIS, trans-
formers, switchgear, lighting, small
power and sensors from the various
rooms.
ENGINEERING
Skema’s scope of work included all
the design and engineering activities,
which were developed through stud-
ies, calculations, verification and val-
idation, and a series of specific de-
tai led procedures to ensure the
correct sequence of operations to
assemble the modules (e.g. removal
of temporary structural parts; seal-
ing; special tools needed to move the
modules; all that is needed to prepare
the structures for transportation).
3D MODEL
Skema’s supply included a 3D model of
the substation, which gives a 360° view
of the whole substation: structural and
architectural parts, electrical and instru-
mentation, HVAC and control disciplines.
The 3D modeling of the substation and
its equipment enables Skema to ensure
a thorough and consistent monitoring of
the most critical areas, a functional di-
mensional verification of the correct po-
sition of the internal elements in the
various areas, and the removal of any
clashes between the elements of the dis-
ciplines that form the model. It also ena-
bles Skema to interface with its Client
efficiently, giving a unique access key to
the project for the success of both the
engineering and construction phases.
SOLUTIONS DELIVERED
110 KV CORE SUBSTATION
The substation is composed of the following areas: > 110 KV GIS ROOM > ELECTRICAL ROOM > BATTERY ROOM > HVAC ROOM > INSTRUMENT EQUIPMENT ROOM
DIMENSIONS (M) 56 X 14.48 X 7.9 WEIGHT (T) 750
In consortium with GE Grid Solutions, Skema was award-
ed the contract for the sizing, design, engineering, mate-
rials, fabrication, inspection, non-destructive examination,
shop-testing, documentation and preparation for shipment
of the Core 110 kV substation for the TCO FGP project.
The substation was divided into 32 transportable pack-
aged sub-modules complete with integral support struc-
ture, access platforms, stairs, electrical equipment and
building services and including the electrical equipment.
