Working closely with its Uralsk-based
partner in Kazakhstan, Skema was responsible for the provision of the PMCC
switchboards for the Atyrau Refinery.
The project proved to be a success
thanks both to the experience acquired by Skema in the Kazakh market
since 1998, which it was able to
leverage fully, and to the important
technology transfer program established with its Kazakh partner.
The commissioning was carried out
by local electrical engineers, under the supervision of Skema’s site

The Baku-Tbilisi-Ceyhan pipeline transports crude 1,760 km (1,094 miles) from the Azeri-Chirag-Guneshli oil field in the Caspian Sea to the Mediterranean Sea. It passes through Baku, the capital of Azerbaijan; Tbilisi, the capital of Georgia; and Ceyhan, a port on the south-eastern Mediterranean coast of
Turkey, hence its name. It is the second longest oil pipeline in the world and one of the biggest engineering projects.
The Chilean LNG Project consists of a new grass-roots LNG receiving terminal located at Quintero Bay, approximately 160 km northwest of Santiago, Chile. LNG carrier ships unload at a new jetty built at Quintero,
into two storage tanks. Process facilities are installed to enable the LNG to be pumped from the storage
tanks, vaporized and exported into the existing transmission system via a new pipeline. The terminal is expected to meet 40% of Chilean gas demand, with an overall annual supply capacity of 2.5 million tonnes of LNG.

Laggan and Tormore are two gas and condensate fields situated about 125 km north-west of the Shetland Islands in the UK. The Laggan and Tormore project involves the development of the two fields and
construction of a gas processing plant and export pipeline. Here, water depths descend rapidly from
an average of 120 m to 600 m and beyond. It is a uniquely challenging environment in which to operate,
but also one with great potential.
The project consists of the development of a production unit for the Yme Project. The Yme field is located in the Egersund basin in the North Sea, approximately 110 km offshore in the Norwegian Continental Shelf. The Yme field consists of two main reservoirs, Beta and Gamma, which are approximately 12 km apart. The Yme Re-development Project is based on a MOPUstor, which is a Mobile Offshore
Production Unit with a subsea storage tank. The MOPUstor will be located at the Gamma reservoir with surface completion of the Gamma wells and tie back of the completed subsea Beta wells.

The Staatsolie Maatschappij Suriname N.V. is located in Suriname, near Paramaribo, in the Wanica District. The project is a major expansion to the existing refinery, and the objective is to increase the
crude capacity at the facility to 15,000 barrels per day. Electrical loads for the above units shall be
fed from the new electrical substation in the L-01 plant.
The Low Voltage Switchgear and
Intelligent MCCs supplied for the
project are equipped with smart
relays that communicate with the
ECMS using the IEC 61850 Protocol,
which affords a number of benefits,
such as interoperability between all
the devices in the substations re-
the life cycle thanks to the introduction of a standardized substation configuration language (SCL).
Since the switchgear is highly modular,
the selection of components required
by any application is very simple.
The result is an appreciable reduction in costs for the secondary system
over its life cycle. The LV bus duct is of
the compact type with copper lines; it
provides a complete solution for connections between power stations and
transformers and the main panel board.
The switchgear’s functional units are
guaranteed arc-proof in accordance
with IEC 62271-200 Standards, appendix AA, class A accessibility, criteria 1 to 5. All the installation, operation
and maintenance operations can be
carried out from the front of the unit.

Discovered in 2007, the Golden Eagle Area (which is made up of reservoirs Golden Eagle, Hobby and
Peregrine), is located in approximately 113 m water depth in the UK sector of the North Sea 70 km offshore (19 km north of the Buzzard Field, 21 km northwest of the Ettrick Field and 4 km south of the
Atlantic Field). The field is developed using two platforms - a wellhead platform and a production,
utility and quarters (PUQ) platform. The two platforms are connected by a 70 m bridge. The facilities being built at Golden Eagle can act as a future hub for tiebacks. Operator Nexen has estimated
the Golden Eagle Area contains 140-150 million barrels of oil equivalent in gross recoverable contingent resources, making it one of the largest oil discoveries in the UK North Sea in recent years.
The Motor Control and Management System (MCMS) developed for
the platforms integrates the intelligent Motor Control Centers made by
Skema with the Process Control System (PCS), the Power Management
System (PMS) and the Distribution
Management System (DMS), and en-
ploits the capabilities of the 400 IEDs
(supplied by different manufacturers)
which measure, protect and control
all the users connected to the MCMS.
Importantly, the MCMS not only helps
the operator to control the users, but
is of great significance to the electrical
engineer in verifying the performances

continuous monitoring of the parameters set in the IEDs with special at-
otal in ensuring a proactive and cost effective maintenance regime of the plant.
All the DCUs components are dual
redundant and can survive any individual component failure. The serial links communicating with the
downstream IEDs via Modbus-RTU

The integration is achieved thanks
to the communication capabilities of the DCUs which operate as
gateways between the upstream
PCS/PMS/DMS and the IEDs within the downstream switchgear.
The DCUs allow concurrent communication via redundant Modubus-RTU
and OPC between the different systems. Such integration completely ex-

reliability/maintenance of the plant.
The MCMS records the running hours,
the number of operations of each

frequent causes of tripping/alarms,
so that the engineer can plan proactive counter measures to avoid future
plant problems which may cause economic losses and, in the worst cases, safety risks to the plant/personnel.
This type of intelligent reporting is piv-
System response times are of utmost importance, the MCMS is designed for ultimate performance. A
command received from the PCS is
actuated by the IEDs in less than
100 ms and the change of status
is available to the PCS in less than
1 second. These performances are
achieved while the DCUs communicate concurrently with the PCS via
Modbus-TCP, with the PMS via Modbus-RTU and with the DMS via OPC.

Senior Expeditor
On 22nd February 2012 Skema was
invited to attend the Jasmine Supplier
Awards for Excellence Ceremony, as
a Nominee among the 15 excellent
suppliers (out of the over 160 suppliers for the project) to the ConocoPhillips Jasmine development project.
ConocoPhillips launched the Jasmine
Supplier Awards for Excellence Programme in January 2011, with the aim
to develop and recognize the Project’s
principal suppliers through setting key
metrics, evaluating business performance, identifying gaps and opportunities for improvement and recognizing and rewarding excellence.
Being one of the best suppliers to
ConocoPhillips is a matter of pride
for Skema, whose nomination in the
“Planning and Delivery” category
was motivated by ConocoPhillips
as follows: “Skema was a bright
star in Jasmine’s electrical success.
Their embrace of SAP’s ERP prior to
Jasmine was evident in their planning,
scheduling, detailed design, material
availability, along with the LV Switchgear’s and MCC’s fabrication.”

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, given 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 onshore processing facility).
