THE GIANT KASHAGAN - KASHAGAN, 80 KM SOUTH-EAST OF ATYRAU, IN THE NORTH CASPIAN SEA, IS THE LARGEST OIL FIELD

DISCOVERED OVER THE LAST THIRTY YEARS WORLDWIDE AND EXTENDS OVER A SURFACE AREA OF APPROXIMATELY 75 KM

BY 45 KM. ITS DEVELOPMENT REPRESENTS ONE OF THE GREATEST CHALLENGES FACED BY THE PETROLEUM INDUSTRY, GIV-

EN THE DEEP, HIGH-PRESSURE RESERVOIR, THE HIGH SULFUR CONTENT, THE SHALLOW WATERS THAT FREEZE IN WINTER AND

THE MARKED SHIFTS IN TEMPERATURE (FROM -30°C TO +40°C). THE POTENTIAL DAILY AVERAGE PRODUCTION AMOUNTS TO

1.2 MILLION BARRELS, WITH ESTIMATED RESERVES OF 38 BILLION BARRELS. THE KASHAGAN PROJECT CONSISTS OF TWO

DEVELOPMENTS: OFFSHORE COMPLEX (ARTIFICIAL ISLANDS IN THE CASPIAN SEA) AND ONSHORE COMPLEX (BOLASHAK ON-

SHORE PROCESSING FACILITY).

MV/LVPACKAGED SUBSTA-TIONSONSHORE

Skema was in charge of the engineering,

manufacturing, testing and commis-

sioning of 9 MV/LV Packaged Substa-

tions. The Substations feed the infra-

structure utilities for the Kashagan field

and are part of the Early Works of the

Kashagan Experimental Programme.

Each Substation was equipped with:

> 10 kV Switchboards

> PMCC LV Switchgear

> Distribution boards

> Distribution transformers

> AC and DC UPS batteries

> Alarm and communication RTUs

> HVAC system

> Electrical Control System

> Project delivered on time and

without any punch list

> Complete project cycle managed

by internal resources: from fea-

LOCALEQUIPMENTROOMSOFFSHORE

Skema was awarded the EPC Con-

tract for the provision of 18 Local

Equipment Rooms (LERs).

The scope of work includes the co-

ordination and monitoring of every

aspect of the project, from feasibility

studies and cost/performance opti-

mization to the design of structural,

electrical, HVAC and safety systems,

procurement, construction, assembly,

commissioning, final inspection and

supervision of on-site installation.

The LERs are pre-fabr icated

steel-structure modules, which have

the following systems installed: Me-

dium and Low Voltage Switchboards,

Transformers, Distribution Switch-

boards, UPSs and relevant Batteries,

supervision and control equipment,

HVAC with provisions for explosive/

dangerous gas injections, electrical

networks, fire-detection and fire-fight-

ing systems and telecoms equipment.

Each LER has an average length of

50 m and weight of 1000 t.

The LERs were built in Ravenna,

shipped to the Caspian Sea on barg-

es and located on artificial islands in

the Caspian Sea.

“First of all congratulations at completing barge 3 and 4

pre-commissioning. Your person-nel and the support offered to

them during their stay here was first class. All concerned were

impressed – our subcontractors, our client and all.”
