Kashagan field development, xperimental programme, Kazakhstan <\/span>
\nKashagan, 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 of approximately 75 km by 45 km.<\/p>\n

Its development represents one of the greatest challenges of the petroleum industry given the deep, high-pressure reservoir, the high sulphur content, the shallow waters that freeze in winter and wide temperature variations from -30 to +40 \u00b0C. The potential average production is of 1.2 million barrels\/ day.<\/p>\n

<\/p>\n

The frame agreement<\/span>
\nBorri was awarded the frame agreement for the provision of AC and DC UPS and batteries, for both offshore and onshore facilities for the Kashagan Experimental Programme. The project, started in 2005, is still in progress.<\/p>\n

The end user of the provision is Agip Kazakhstan North Caspian Operating Company (Agip KCO), which is the operator (in 2009 it has been changed into NCOC) on behalf of the consortium comprising Eni, Shell, Total, ExxonMobil, KazMunayGas,
\nConocoPhillips and Inpex.<\/p>\n

The contractors include Saipem, Aker Solutions, Bateman-Litwin, Consafe Mc Nulty, SBM Siemens, GE Nuovo Pignone, Tekfen, Renco, Rosetti Marino, Montazspetsstroy (MSS), ABB, Punji Lloyd, Petrofac. The Kashagan Project consists of two developments: Offshore Complex and Onshore Complex.<\/p>\n

Offshore Complex: artificial islands in the Caspian Sea<\/span>
\nAs part of the experimental programme and in support of drilling operations, Agip KCO has already constructed a number of rock structures that became known as \u201cartificial\u201d or \u201cdrilling\u201d islands.<\/p>\n

In total, four drilling islands, Island A and Island D for Kashagan and two separate islands for Aktote and Kairan, have been built.<\/p>\n

More artificial islands will be built as the project progresses and will be linked between themselves and onshore operations by pipelines.<\/p>\n

Onshore Complex: Karabatan onshore processing facility<\/span>
\nAgip KCO operations continue onshore, 35 km North- East of Atyrau. The works started in 2002.<\/p>\n

When constructed, the onshore processing facility will receive oil and gas delivered from offshore in order to produce export quality oil and gas for further sale, as well as fuel gas for use at the Agip KCO onshore and offshore facilities.<\/p>\n

Solutions delivered<\/span>
\nThe development will comprise a combination of both offshore and onshore processing facilities. The offshore production facilities will be tied to the onshore oil and gas processing and storage facilities to be located in a \u201cgreenfield\u201d location approx 35 km North East of Atyrau.<\/p>\n

The experimental programme is to be developed in three \u201ctranches\u201d, sequenced, with intervals of six months between tranches 1 & 2 and two years between tranches 2 & 3: the off shore plants include various barges (raw gas injection, flash gas compressor, living quarters, power generation etc.) assembled in different construction sites and then moved to the Caspian Sea;
\nthe on shore plants (power plant, substations, oil & gas, sulphur treatment etc.) is located in Karabatan.
\nThe potential average production amounts to 1.2 million barrels\/day, with estimated reserves of 38 billion barrels.<\/p>\n

AC and DC UPS\u2019s and batteries <\/span>
\nAC UPS\u2019s and backup batteries are required to feed with clean and secure power supply all the critical ac electrical loads such as:
\n\u2022 instruments & telecoms loads (230 V AC, 1 ph, 50 Hz, dual configuration, with 2, 3 or 8 hours back up time);
\n\u2022 escape lights (230 V AC, 1 ph, 50 Hz, single configuration, with 2 hours back up time).
\nDC UPS\u2019s and backup batteries are required to feed
\nwith clean and secure power supply all the critical DC
\nelectrical loads such as:
\n\u2022 switchgears trip & close (110 V DC, dual configuration, 8 hours back up time).<\/p>\n

Karachaganak development project, Kazakhstan<\/span>
\nThe Karachaganak field, located onshore in western Kazakhstan (about 150 km to the East of the city of Uralsk), was discovered in 1979 and is one of the largest gas and condensate fields in the world.<\/p>\n

Covering an area of 280 km2 and holding over 1.2 billions tons of oil and condensate and 1.35 trillion m3 of gas, the giant Karachaganak field currently products an average of 150,000 barrels\/day of condensate and 20 million m3\/day of gas.<\/p>\n

The Karachaganak 4th Stabilisation & Sweetening Train Project aims to increase the capacity of the existing Karachaganak Processing Complex (KPC) facilities through the addition of a fourth train. The expansion of the field has involved an investment of over 5.5 billion dollars and it is currently the biggest internationally funded project in Kazakhstan.<\/p>\n

Today, Karachaganak is producing at record levels and is the largest gas producing field in Kazakhstan, accounting for some 45% of the country\u2019s total gas production and around 16% of total liquids production.<\/p>\n

In 2009 the venture produced some 139.4 million barrels of oil equivalent.
\nThe Karachaganak Venture brings expertise and knowledge from four international oil & gas companies:
\nBG Group, ENI, Chevron and Lukoil, the end users of the provision. The Engineering and Construction Management was awarded to the joint-venture Becthel Ltd and Snamprogetti UK, apart from 4th stabilisation & sweetening train project, where the EPC contract was awarded to Petrofac.<\/p>\n

Solutions delivered<\/span>
\nAC UPS\u2019s and nickel-cadmium batteries are required to feed with clean and secure power supply all the critical ac electrical loads such as:

Borri can rely on its international organisation, based on several subsidiaries and widespread partnerships, in order to manage multinational projects, where the players, such as consultants, EPC companies and end-users, are located in different countries.<\/p>\n

For Borri, local content means the development of local skills and know-how transfer, strengthen local manpower and entrepreneurship through its business.<\/p>\n

Even in Kazakhstan a local partnership to perform primarily service activities, such as start-up, commissioning and maintenance, provides considerable social benefits to the host country, in terms of investments, employment, development of
\nsubcontractors and other factors.<\/p>\n

<\/p>\n

UPS systems supplied by Borri<\/span>
\nAC and DC UPS systems are primarily designed to meet requirements for applications in the oil & gas, petrochemical, chemical and power generation industries.<\/p>\n

They are typically designed for production process plants, refineries, pipelines, gas-gathering plants, LNG plants, storage plants. They suits to the basic concepts of reliability, robustness and durability, since these industrial products are commonly requested to operate under the most severe environmental
\nconditions.<\/p>\n

UPS systems ensure quality power supplies for pumps, control devices, fire-fighting systems, emergency lighting, air conditioning and other essential equipment.
\nBorri daily work is to deliver customised tailor-made solutions, designed to meet any specific application requirement.
\nThese systems are designed to meet an industrial product concept, which includes IP41 protection degrees, true front access to all of the components, special painting methods, flame retardant halogen free cables and colour-code identification of internal cables.<\/p>\n

Acting as an interface between the mains and sensitive applications, UPS\u2019s supply the load with continuous, high quality electrical power regardless of the status of the mains. UPSs deliver a dependable supply voltage free from all mains disturbances, within tolerances compatible with the requirements of sensitive electronic devices. UPS can also provide this dependable voltage independently by means of a power source (battery) which is generally sufficient to ensure the safety of individuals and the installation.<\/p>\n

Borri supplies static power supplies, based on silicon devices, including high frequency controlled IGBT switches. The machine digital control can rely on very advanced microprocessors (figure 3).<\/p>\n

The UPSs can be supplemented with additional features: an automatic static by-pass in the case of UPS overload or fault, a mechanical maintenance by-pass enabling the UPS to be completely isolated, as well as various options for signalling and maintenance. It is possible to combine more than one UPS in parallel to increase the reliability of the supply by providing one redundant unit (figure 4).<\/p>\n

As above mentioned, the supplies are made up of DC UPS (rectifier and charger), single phase output AC UPS and three phase output AC UPS.<\/p>\n

\u2022 DC UPS: RTB model 400 V AC, 3 ph, 50 Hz input, 110 V DC output 100 to 500 A (available up to 2000A), in dual configuration
\nfor redundancy with integrated 110 V DC distribution panel at a fine regulated voltage tanks to drop cells stabiliser, which prevent the variable battery voltage from feeding directly the loads.
\n\u2022 AC UPS: E2001 model 400 V AC, 3 ph, 50 Hz input, 230 V AC, 1 ph, 50 Hz output, 110\/220\/400 V DC battery voltage, ranging 5
\nto 200 kVA in single and dual configuration for redundancy with bypass isolation transformer and integrated 230 V AC distribution panels (figure 5-6).
\n\u2022 AC UPS: E3001 model
\n400 V AC, 3 ph, 50 Hz input, 400 V AC, 3 ph, 50 Hz output, 400 V DC battery voltage in dual configuration for redundancy with bypass isolation transformer and integrated 400Vac distribution panels comprising 400 V AC drive systems for HVAC (Heat Ventilation Air Conditioning) supply.
\n\u2022 Batteries
\n— Saft NiCd with gas recombination units, SBH\/SBM\/SBL model for on-shore plants, 2\u20138 hours autonomy time and capacity up to 1450 Ah.<\/p>\n

— Fiamm VRLA Gel type, SMG model for off shore plants, 2\u20138 hours autonomy time and capacity up to 3000 Ah.
\nThe batteries are disconnected via wall mounted Eexd IIC T3 battery breaker box with 24 V ESD circuit.<\/p>\n

\u2022 Battery discharger
\nReverse operation of the rectifier\/charger to automatically discharge battery into ac mains is a unique feature. The battery is discharged back into the mains, with:
\n— constant current;
\n— power current;
\n— individual profil.
\nThis feature is specifically designed in order to fully test
\nthe battery, to simulate the load according to a typical<\/p>\n

load profiles and to recover energy, saving money and without using special and costly load banks.<\/p>\n

User interface and remote monitoring<\/span>
\nBorri UPS systems are supplied with user interface and remote monitoring solutions for continuous real time monitoring and performance analysis of UPS and other power equipment. To meet the end users needs looking for tailor-made solutions, the units are equipped with front display with mimic and led\u2019s, lamps and meters which allow a local monitoring. In addition a remote monitoring is guaranteed via relay contacts and an advanced
\ncommunication way based on the Modbus protocol.<\/p>\n

<\/p>\n

A Modbus connectivity device fitted on each machine provides continuous, reliable and accurate remote monitoring of a UPS system through a Building Management System (BMS) or Industrial Automation System (IAS).<\/p>\n

The Modbus protocol, one of the most commonly used communication standard in industrial environment, defines a message structure that controllers will recognise and use, regardless of the
\ntype of networks over which they communicate.<\/p>\n

The UPS connects to the network via RS-485 port. The port provides the means to integrate data from the UPS into the
\nuser-provided management system. Key power quality and UPS status information may be monitored in real-time to aid in the management of the UPS and notification of potential power problems.<\/p>\n
