Transportation pipelines andstorage:Pipelines are the safest, most reliable and cost-effective way of transporting largevolumes of oil and gas. Pipeline systems link typically remote production fields tourban centres and/or terminals and ports for export.

As the main energy highways for oil and natural gas, pipelines and their associatedstorage, pumping, compression and monitoring facilities represent a key opportunityfor Schneider Electric worldwide.

Key performance indicators for pipelines operators include:

� Batch integrity

� Batch quality

� Capacity

� Availability

� Reliability

� Change order capacity

To maximize these parameters, pipeline operators require a complex networkof automation, control and electrical distribution products integrated in an overallsolution that is usually developed by systems integrators. This presents anexcellent opportunity for Schneider Electric, as these systems integrators relyon Schneider Electric’s technical expertise in providing leading-edge controland automation systems.

More than 60 kinds of unprocessed and refined petroleum move through pipelines.A pipeline network is made up of different line sizes and types that can be groupedinto two categories:

� Gathering lines

� Transportation lines

Typically, the smallest diameter pipelines lead out of production fields and intoend-user homes (in the case of natural gas). The largest diameter pipelines are themain transmission pipelines between source fields and urban areas.

Gathering linesFlow and gathering lines move crude oil and natural gas from the wellhead overshort distances to oil batteries (field facilities for initial processing) and natural gasprocessing facilities where impurities are removed and natural gas is separated intovarious products. Oil and gas producers operate flowlines (over approximately fivemiles) from pumping to central storage locations.

Flow line diameters range from 60.3 mm to 114.3 mm (2 in. to 4 in.). Gathering linesvary in size from 114.3 mm to 323.9 mm (4 in. to 12 in.).

Feeder lines move crude oil and natural gas products from batteries, gasprocessing facilities and storage tanks in the field to the long-distance haulers of thepipeline industry, the transmission pipelines.

Feeder pipelines diameters measure between 168.3 mm to 508 mm (6 in. to 20 in.).

Transportation lines Transportation or transmission lines are the main energy highways. They connectcrude oil and natural gas producers with refineries, processing plants anddistribution centers. Natural gas and crude oil transmission lines are between 508mm to 1219 mm (20 in. to 48 in.) in diameter. Petroleum product pipelines rangein sizes from 168 mm to 324 mm (6 in. to 12 in.).

Distribution lines are operated by local distribution companies, cooperatives andin some cases, governments. Natural gas is moved along distribution pipelines tohomes, businesses and some industries. Sizes of these lines can be as large as914.4 mm (36 in.). Most, however, are much smaller, ranging between 21.3 mmand 168.3 mm (1/2 in. and 6 in.).

From wellhead to pipeline: oil

Crude oil is pumped through flowlines and gathering lines from producing wells to an oil battery for initial processing. The main component of a battery is one or moretanks where basic sediment and water sink to the bottom and natural gas bubblesoff the top.

Clean oil collects in the middle. The associated gas or “solution gas” from thisprocess is directed to gas processing plants, if sufficient quantities make thiseconomically viable. Otherwise, it is flared or incinerated.

From wellhead to pipeline: natural gas

An in-field natural gas production site includes facilities to measure the gas, andremove water, oil, sulfur and other impurities.

After initial processing, the gas flows into gathering pipelines that transport the gas to a transmission pipeline or another processing plant. Here, natural gasliquids and other impurities are separated from the methane (the main componentof natural gas).

Pipeline process flow

Oil derrick

From wellhead to custody transfer

The natural gas liquids such as propane, butane, ethane and condensates aretypically piped to other facilities:

� Condensates are piped to heavy oil producers to be used as diluent to promoteflow of heavy oils through a pipeline.

� Propane is piped to point-of-sale marketers.

� Other natural gas liquids are piped to petrochemical plants for use in themanufacture of plastics, for example.

From extraction to dilution: bitumen and heavy oil

Bitumen and some heavy oils are too viscous to flow through pipelines, so diluentsare added to change the viscosity. Condensates derived from natural gasseparation are a traditional diluent, but light crude oil can also serve in this role.

In the case of Syncrude Canada Ltd., bitumen is refined into a synthetic crude oil(containing no residue or very heavy components) directly at its site in NorthernAlberta and then piped to southern markets (see www.syncrude.com for moreinformation).

Storage

Petroleum storage facilities are located throughout pipeline systems at:

� Batteries,

� Upstream pipeline hubs (culmination points of gathering pipeline systems), and

� Petrochemical plants and refineries where various petroleum products are made.

Ownership of storage varies. Oil companies can own the storage as can pipelinecompanies. Multiple stakeholders may also jointly own storage.

Tank farms are clusters of large above ground oil storage tanks. More temporarystorage facilities are typically located at the initiating end of a transmission line.More long-term storage for point-of-sale purposes is common at the end of a line.Each storage facility is a pipeline system in miniature, requiring distribution andcontrol equipment, but mainly automation equipment for custody transfer measuring(the legal transfer of petroleum products from a supplier to a customer).

While crude oil from offshore production is delivered to onshore tank farms byseabed pipelines, production can also be stored in a fixed platform or on a floatingproduction/storage/and offloading vessel. It is then transferred to a tanker forshipment to terminals worldwide.

Pressure tanks for the storage of natural gas are expensive, so underground saltcaverns or depleted natural gas fields are commonly used.

Offshore oil platform

LNG handling and storage typically involves a three-step process.

� Natural gas is “frozen” into a liquid state through a complex cryogenic processcalled liquefaction involving temperatures as low as -160˚C.

� LNG can be stored in cryogenic holding tanks or pumped directly from the coolingvestibule into special insulated vessels, such as railcars, trucks, or ships fortransportation.

� At the final destination, it is pumped from the vessel into either another cryogenicstorage facility for later delivery or directly into a re-gasification unit, which usesseawater or air to reheat the LNG, converting it back into a gaseous form.

Natural gas liquids can be stored in cylindrical or spherical tanks, but largervolumes are also stored in underground salt caverns as deep as 5,000 feet.

Driving liquids through pipelines

Liquids are propelled through most pipelines by centrifugal pumps (located atpumping stations), that are in turn powered by electric motors. In remote areas,power sources include both diesel engines and electric motors. Oil moves throughtransmission pipelines at four to eight kilometers per hour and may take a month ormore to travel 4000 kilometers.

Various grades of gasoline, oil and condensate can move through the same pipelinein batches (or slugs), similar to railcars in a train. Simple hydraulics and fluidproperties prevent batches from mixing except where they actually come in contactwith one another. Those small volumes are then reprocessed.

Driving gas through pipelines

Natural gas-fired turbines typically drive centrifugal pumps, compressing gas fortransmission. Pressures in some of the largest transmission lines can run upward of7000 kilopascals (1000+ pounds per square inch). The drives to create thispressure can be as much as 35,000 horsepower, propelling natural gas at up to 40kilometers per hour in the line. Distribution line pressures can start at 3450 kp (500psi), but can drop to as low as 690 kp (100 psi) in new residential areas.

10

Pumping, booster and compressor stations

Pump stations on liquids pipelines represent the best prospects for SchneiderElectric power distribution, control and automation equipment because theircentrifugal pumps are driven by electrical motors. Natural gas lines, on the otherhand, are usually powered by natural gas burning turbines, which usually areprefitted with electrical equipment at the OEM level. Some gas compression stationsare also powered by electric motors.

To maintain the flow of liquids through the line, booster stations are spaced at 25 to100-plus kilometer intervals depending on terrain, the type of pipeline and theviscosity of the products being moved. Compression booster stations are spacedfurther apart because the product is lighter.

Pumps under maintenance at a pumping station

Typical sequence in which petroleum flows through a products pipeline

Configuration

A typical pump or compressor station consists of a cluster of buildings:

� A compressor or pump building with compressors or pumps (on flowlines, smallpump units are sometimes left in the open),

� A laboratory building to monitor the quality of product being received into thepipeline system,

� An office for field technicians, and

� An electrical/controls building, which could be a separate building atlarger stations or a prefabricated electrical building (PEB) supplied byspecialty packagers.

Pumping stations also contain a storage building for lubricants andenvironmental supplies.

Electrical power requirements – pipeline applications

Application #1 – Gathering lines

Although configurations vary from company to company and region to region,pumping/booster stations on gathering lines – starting with four-inch pipes thatfeed into larger pipes up to 24 inches in diameter – will usually have:

� Three electric motor drives in series – two operating, one backup – from 1000 hpto over 4000 hp,

� 5 kilovolt incomer for motor drives,

� One step down transformer to 480 V for all equipment and valves below 200 hp,

� One step down transformer to 120 V for lighting and heating,

� One step down to 24 V DC for control equipment.

11

Process flow diagram

Application #2 – Transmission lines

A petroleum product transmission pipeline can have a smaller diameter than acrude oil pipeline because of the lower viscosity of these refined products.

Transmission line booster stations are located between one and 300 kilometersapart, depending on terrain (the average distance works out to 75 kilometers). A typical petroleum products line runs diameters of 6 inches to 24 inches in itssystem. Each pump/booster station on a transmission line has:

� Two 1000 hp electric motor drives in series (one operating, one backup),

� 25 KV incomer for motor drives,

� One step down transformer to 5KV for main motor drives,

� One step down transformer to 600V for all equipment under 200 hp,

� One step down to low voltage three phase 240V and 120V,

� 24 V DC for control equipment.

The diagram on page 18 illustrates this application.

Pipeline monitoring systems and SCADA roomsThe size and length of a pipeline, the range of products it carries, and the number of distribution points determine the complexity of a pipeline monitoring system.

The heart of a pipeline monitoring system is the supervisory control and dataacquisition (SCADA) system. This gives a “big picture” overview of all pipelineactivities and allows the operator to regulate the entire length of the pipeline from a single control centre.

Essentially a central computer room, the control centre is staffed around the clockby skilled operators to maintain full operations of the pipeline. A digitalcommunications network – consisting of a conventional telephone line, cellular orsatellite communications – supports the computer control system.

The SCADA systems on transmission lines are usually transmitted over satellite.However, depending on the region, pipelines can also be controlled overmicrowave, spread spectrum, radio, dedicated land lines, or intranet networks usinga combination of copper, fiber optics and wireless technology.

The four legs of a SCADA network are

� Field instruments and devices,

� Station control using programmable logic controllers (PLCs) and/or remoteterminal units (RTUs),

� Master terminal units (MTUs),

� The control centre.

RTUs may be PLCs that collect field information – such as valve on/off/in transitionstatus, power distribution, temperature and pressure. The RTU relays thisinformation to the control centre.

Located at each pumping station along the length of the pipeline, the RTUs allowthe central control room operators to compare computer calculations of actualproduct flow and pressure with expected values in order to identify anomalies and totake action if necessary – including shutting down an entire pumping station. In thisway, thousands of kilometers of pipeline can be managed from one central locationwith the click of a mouse. The systems architecture for a compression stationcontrol system appears on the following page.

Custody transferThe legal transfer of petroleum products from a supplier to a customer is referred toas custody transfer. The SCADA system facilitates centralized customer batchtracking, custody transfer metering and product control to ensure batch integrity.Control centre operators are in close communication with field operating techniciansto ensure accurate custody transfer.

One method of custody transfer uses densitometers – devices that measure batchdensity. Batches are separated by buffers – usually of a synthetic crude oil ofsufficient density that it does not mix with the customer batch crude. Densitometersrelay batch density information in real-time to the SCADA system and allowoperators to track and divert specific batches.

Industry standard Modbus communication between pipeline operators andcustomers is becoming increasingly important, as customers require vital crude oilbatch data for accountability and leak detection systems.

Easily configured for different applications, PLCs are ideally suited for custodytransfer applications because they have a very high mean time between failurerating, even in harsh oil field environments. They also support large data storagerequirements and offer security features including the ability to set Memory Protectto secure the configuration, program and accumulated values.

Electrical and automation equipment certificationrequirements

International standards

Most Schneider Electric power distribution, industrial control and automationequipment is built to international CE, IEC and NEMA standards. Some equipmentcarries TÜV SIL 1 and SIL 2 certification.

Local standards

Some regions and countries require additional local certification.

� Canada: CUL or CSA certification

� United States: UL or FM certification

� North America: ANSI certification

Metal-clad switchgear, as defined by ANSI C37.20.2 must include:

� Removable (drawout) circuit breakers,

� Fully compartmented construction,

� Grounded metal barriers that enclose all live parts,

� Automatic shutters over primary contacts,

� Fluidized-bed epoxy insulated bus, and

� Disconnect-type voltage transformers.

Medium voltage controllers, as defined by UL, CUL, ANSI, EEMAC and IEC,must have

� Maximum voltage of 7.2 kV,

� Third party certification,

� Safety interlocks,

� Isolation switch with maintenance-free contacts capable of 5,000 operations.

Oil and gas leak detection equipment SCADA and automated equipment that detects and contains oil or gas leaks ishoused in a weatherproof line block valve station. Often required every fewkilometers along a pipeline, line block valve stations can instantly shut down theaffected section of pipeline – between pumping stations, or between line block valvestations – to minimize damage resulting from leaks.

19

Global pipeline mileage and projectsConstruction costsUnder ideal conditions, transmission pipelines cost about CDN $1 million perkilometer (approximately US $1.25 per mile) to build. Compression stations runabout CDN $30 million (US $24 m) to build.

North America

New and planned pipeline mileage in North America has slightly increased overthe past year from 12,111 to 14,296. Two promising prospects for future NorthAmerican construction are the long anticipated 2,100-mile Alaska HighwayPipeline to bring natural gas south from the North Slope and the 756-mileMackenzie Gas project to ship gas from the Mackenzie River Valley tonorthwestern Alberta. In recent months, there’s been a flurry of activity in Alaskaand Canada involving these projects.

US Congress passed two bills in October 2004 which contained incentives tobuild a natural gas pipeline from the North Slope to the Midwestern USA. The billscontain numerous provisions including one authorizing up to $18 billion in loanguarantees.

In Canada, Imperial Oil and its partners filed applications in October 2004 withregulatory authorities to construct the $7 billion Mackenzie Valley gas pipeline.The system will connect an estimated 6 Tcf of natural gas in the Mackenzie Deltawith an existing pipeline in northern Alberta. Ultimately, the pipeline will deliver1.2 Bcf/d of gas to North American markets.

Schneider Electric’skey offering

We offer a complete products, equipment & systems portfolio,which includes MV & LV power distribution, motor controls,automation & industrial controls.

Medium voltage arc-mitigating switchgearThis switchgear

� Increases uptime because damage is limited when in a fault condition,

� Are user-friendly,

� Feature windows-based software,

� Have a high mean time to failure (over 50 years).

22

Medium voltage motor controllers

Schneider Electric medium voltage motor controllers offer a competitive advantagebecause of their compact footprint and enhanced safety features. The safetyfeatures include

� Load discharge assembly,

� Compartmentalization,

� Arc-resistant enclosure,

� Grounded isolating switches.

Software

This software features:

� Hot-standby capabilities for critical applications,

� A built-in, interactive operator screen to streamline maintenance,

� A full-function simulator to enable application bench testing,

� User-defined function blocks to simplify programming,

� Ability to program in five different languages – Structured Text, Ladder,Function Block, Sequential Function Chart, and Instruction List,

� Data array structures and math capabilities that facilitate the development ofModbus Plus routines.

Software reduces programming time and software investment costs, because theprogrammer can reuse function blocks designed for previous projects.

This capability is especially important for applications such as

� Sectionalizing valves, where there are common inputs and outputs used ateach station.The software can map these common I/Os to the standard variablenames regardless of the I/O points’ physical location.

� Developing a standard analogue scaling block to ensure repeatability ofdensitometer signals for multiple sites.

Hot standby PLCs

These auto-configurable, Unity-compatible controllers require no setup or specialhardware. Designed to protect against power supply, CPU or I/O driver modulefailure, they also provide:

� Exceptionally fast scan and transfer time,

� High availability, dependability and security required by critical processapplications such as petrochemical facilities and tank farms. (Because tank farmshave no surge capacity and are located at various points along the pipeline system, afailure in the tank farm control system can potentially impact the mainline pipelineoperations.)

� Bumpless, controlled transfer with minimal process impact. This ensures thatcritical processes running on a remote I/O network remain intact and unaffected bycontroller hardware failures – thereby increasing productivity and reducing downtime.

Additional benefits:

� Default assignment of the primary PLC, based on the MAC address, makesthe system plug and play.

� Both PLCs may be placed as much as 2 km apart.

23

� Applications are automatically downloaded from primary to standby.

� Logic mismatches are configurable via Unity Pro or by the command register.

� Existing I/O drops can be used.

� There is no need for a dedicated module or software.

� Default configuration and native, preconfigured functions eliminate the need forspecific executive software.

The fact that the Unity/Quantum hot standby solution does not require programmingis unique.

Oil and gas flow measurementSchneider Electric PLCs are ideally suited for gas flow measurement (by volume orweight over a specific amount of time). Calculations are provided as an integratedhardware and software solution in the PLC processor, providing the complex controlschemes required by pipeline applications.

� Ethernet TCP/IP, Mobdus and the web: Recognized standards

Schneider Electric’s strongest value proposition to the pipeline sector istherefore an offer featuring power distribution and/or industrial controlequipment, combined with Unity software, Quantum hot standby PLCsand/or Transparent ReadyTM. Equally strong is Schneider Electric’scustomized RTU offer for boosting/pumping station applications.

The following success stories attest to the strength of this offer.

Turkey: Transparent ReadyTM will facilitate refinery substation automationSchneider Electric Turkey’s largest project to date entails automating a petroleumcompany’s substation with:

� Modicon® Quantum™ PLCs running on a Unity hot standby configuration,

� PLC CPUs,

� Transparent ReadyTM Ethernet modules.

A one millisecond (ms) time stamp must be put on selected digital inputs.All systems must be synchronized to 1 ms accuracy. GE protection relays, QuantumPLCs and digital input modules must be adjusted to the same millisecond level forelectrical system fault analysis.

Initially, Schneider Electric Turkey was going to suggest installing: � Concept software for the Modicon® Quantum™ PLCs,

� 140ERT85410 modules for time stamping,

� STS3000 Merlin Gerin products to synchronize the ERT and protection relays.

24

However, after seeing the successful operation of Transparent Ready’s Ethernet-based Network Time Protocol (NTP) at Spain’s Madrid Barajas Airport,Schneider Electric Turkey suggested installing:

� Unity software.

� Modicon Quantum PLCs with 140CPU6760 Hot-Standby CPUs.

� Transparent ReadyTM Ethernet modules for NTP.

This solution was key to securing the project.

North America: Square D Motor Logic Plus 2 dual port relay will allowfuture real-time monitoring of overloads at an oil refinery

The Square D Motor Logic Plus 2 relay’s dual ports (DeviceNet™ and Modbus®) willfacilitate modernizing a North American oil refinery’s MCCs. (For safety reasons,each section of these hard-wired MCCs has a termination cabinet to isolate fieldcontrol devices from line voltages.) Schneider Electric won this order because theywere the only manufacturer who could provide an overload relay with:

� Dual ports (DeviceNet™ and Modbus®) (Competitors’ equipment were solelyDeviceNet-compatible).

� A second communication port making possible a future Transparent ReadyTM

option for overload setting and monitoring.

The Motor Logic Plus 2 relay’s open, Ethernet-based communication capability willfacilitate:

� Controlling, programming and monitoring remotely using standard automationequipment.

� Redundant communication directly to each motor starter.

This solution is illustrated on next page.

Glossary of Terms

Batches Different commodities can be sent through liquidspipelines. They are sent in batches similar to themovement of railcars in a train. There is no intermixing ofthese liquids except in small quantities where they contactwith one another. Liquid “buffers” are often insertedbetween batches to maximize batch integrity.

Battery An in-field processing facility to separate crude oil fromother substances such as natural gas, carbon dioxide,saltwater, sulfur compounds and sand.

Bitumen A semisolid hydrocarbon mixture. The oilsands bitumen inCanada is the world’s largest known hydrocarbonresource.

Booster stations Pump or compressor stations along the length ofpipeline to maintain flows.

CMB(coal bed methane)

Methane trapped within coal beds.

CO2/Nitrogen/Water flood

Secondary recovery techniques that involve floodingreservoirs with these compounds to bring maintainpressures or to make crude oil or natural gas more readilyavailable for extraction. A part of this is CO2 sequestration,which involves injecting CO2 into a formation and derivingthe twin benefits of dislodging methane and storing CO2underground rather than releasing it into the atmosphere.

Condensates Liquids obtained from natural gas, traditionally used as adiluent to promote flow of heavy oils through a pipeline.

Crude oil A naturally occurring liquid mixture of hydrocarbons. Itincludes complex hydrocarbon molecules. Crude oil isoften mixed with other substances such as natural gas,carbon dioxide, salt water, sulfur compounds and sand,which are separated from the liquid hydrocarbons in filedprocessing facilities called batteries.

Custody transfer The legal transfer of petroleum products from a supplierto a customer.

Denistometer A device that measures product density.

Diluent Liquids used to promote flow of heavy oils througha pipeline.

Heavy oil Thicker grade of oil commonly used in asphalt roadconstruction but also for upgrading into lighter petroleumproducts. Heavy oil sometimes requires the addition ofcondensates to be able to flow through pipelines.

Hydrocarbons Compounds of hydrogen and carbon. The simplesthydrocarbon is methane (CH4).

33

LNG(liquefiednatural gas)

Supercooled natural gas maintained as a liquidat -160˚C. LNG occupies 1/640th of its original volumeand is therefore easier to transport if pipelines arenot available.

Natural gas Mainly methane, although it can exist in a form that isnaturally mixed with ethane, propane, butane andother substances such as carbon dioxide, nitrogen,sulfur compounds and helium. These compounds areseparated from the methane at processing plantslocated near producing fields.

Oilsands A semisolid hydrocarbon mixture of sand and bitumen.Also refers to the region around Fort McMurray, Alberta,Canada, the world’s largest known bitumen resource.

Petroleum A general term for all naturally occurring hydrocarbons –natural gas, natural gas liquids, crude oil and bitumen.

PEB Prefabricated electrical building supplied by specialtypackagers.

RTU (remoteterminal unit)

A device that collects and sends data to the SCADA hostsystem over a wired or wireless network.

SAGD(steam assistedgravity drainage)

An in-situ oilsands extraction technique. Steam is pumpedinto the ground over the course of months to mobilize thebitumen downward where a horizontal well pumps themixture to the surface.

SCADA(supervisory control and dataacquisition)

A wire or wireless central control system used to monitorand maintain operations of larger pipelines.

Synthetic crude oil Oil upgraded from heavy oil or bitumen containing neitherresidue nor very heavy components.

Tank farms Oil storage facilities.

Western Canada’sSedimentary Basin(WCSB)

Prehistoric seabed stretching from the Rocky Mountainfoothills to the border of Saskatchewan.
