TELECOMMUNICATION FACILITIES FOROPERATION AND MAINTENANCE OF

OIL AND GAS PIPELINE

1 SCOPE

This standard enlists various types of telecommunicationfacilities required for smooth and eftlcient operationand maintenance of oil and gas pipelines.

2 TEL-ECOMMUNICATION FACILITIES

For the efficient operation and maintenance of oiland gas pipeline system, typically followingtelecommunication facilities have been provided:

2.1 Voice-Communication Facility

Following voice communication facilities are provided:

a)

b)

[nter-Ofice Voice and Fax CommunicationFacili@ — For the inter-ofllce communication,the direct telephone dialing facility betweenthe manned stations/locations of the pipelinenetwork shall be provided. This facility shallenable selective as well as multi-partyconference calls, involving the users of sameor different stations.

If required, facsimile communication mayalso be provided amongst all attended stationsfor office communication purpose.

Communication Facility for PipelineMaintenance — For pipeline maintenancepurpose, dedicated voice communicationfacility (using normal DTMF telephone) isprovided at all pipeline stations (unmanned/manned), SCADA Master Control Center(SMC), Telecom Network ManagementCenter (TNMC) for pipeline maintenancegroup.

For the same, one telephone shall be installedin each station, which is connected over longextension cord (depending upon the distancebetween telecom room and field, typically25 m) for taking the telephone set to the fieldduring any O&M activity. In certain cases,an explosion proof telephone with acousticbooth may be installed in hazardous area ofpipeline station for voice communication.Using this telephone, multi-party conferencecall (typically 4 to 8 users) shall be possible.

In case of longer pipeline, if the same is

divided into number of O&M jurisdictions,dedicated voice channel for each jurisdiction,having connectivity with SMC and TNMCmay also be provided having selective andmulti-party conference call facilities.

Depending upon the pipeline maintenancephilosophy, pipeline maintenance telephoneof all stations may be connected .cwer omni-bus VF channel, which allows selective andconference calls.

c) Communication Facili@ for Pipeline StationWatchmen — For watchman communication,each pipeline station (unmanned/manned)shaII be provided with telephones. For thesame, the telephone connection fi-omtelecomroom to be extended to watchman room at allthe un-manned stations and to the security in-charge room at manned stations.

Depending upon security policy any of, thefollowing communication facilities may beprovided:

1)

2)

3)

Watchmen at unmanned stations shall beable to contact only the security-in-charge and no two watchmen unmannedstations will be able to talk to each other.

Watchman and -security-in-chargetelephones shall be on omni-bus channel,which allows selective and conferencecall.

Normal point-to-point selectivetelephone dialing facility amongstwatchmen and security-in-charges.

Depending upon the environment condition,wherein the watchman telephone shaIl bedeployed, the normal or weather proof orexplosion proof type of the telephone maybedecided.

d) Engineering Order Wire (EO W) — Fortelecom maintenance purpose, omni-buscommunication channel is provided, whichis generally the integral part of telecomtransmission equipment.

2.2 Communication Facility for SCADA Application

Depending upon the SCADA system architecture, the

1

IS 15655:2006

following types of communication channels/links arebeing provided, which should be compatible to RTU(Remote Terminal Unit) of various pipeline stationsand SCADA Server installed at SCADA MasterControl Station (SMC):

a) Channel for RTU polling — Any of thefollowing channels shall be provisionedbetween SCADA Master station and variouspipeline staticms far polling of RTU bySCADA server:

1)

2)

3)

4)

Omni-bus analog channel(s)

Omni-bus low speed async data (RS232)Channel(s) ( 1.2–1 9.2 Kbps) [Y-type,C-type]

Point-to-point low async speed (RS232)Data Channel(s) (1.2–19.2 Kbps)

10/100 Base T ethernet channel

NOTE — The transmission system shall ensurethat the above RTU channels preferablyuninterrupted in case of failure of path orequipment, using suitable protection mechanism,

b) High speed channel between SCADA masterstation (SA4C) and remote work stations —For making various SCADA data, which arecollected at SCADA master station, availableat manned stations, point-to-point high-speedsynch (n x 64 kbps) data channels: V.24 orV.35 or G.703 [for2 mbps] or 10/100 Base Tethernet channels are being provided betweenSCADA master station and manned stationsof pipeline.

c) Backup channel between main SMC andstand-by SMC — For data synchronizationbetween SCADA master stations [main andstand-by], high-speed synch (n x 64 kbps)data channel(s): V.35 or G.703 [for 2 mbps]or 10/100 Base T ethernet channels areprovided between main and stand-by SMCS.This backup channel(s) is (are) required tobe provided over alternate telecomtransmission path between SCADA masterstations.

2.3 Mobile Communication Facility

To enable pipeline maintenance personnel tocommunicate with the maintenance base, while onmove or carrying out the job along the pipeline, mobilecommunication system, operating in the pipelinecorridor, shall be provided.

This mobile communication sets shall have vehiclemounting provision and shall facilitate the followingmodes of communication:

a) Mobile to mobile communication,

b) Mobile to base station communication andvice-a-versa, and

c) Mobile to any Telephone subscriber anywherein pipeline route and vice-a-versa.

This mobile communication system typically may beany of the following type:

a) VHF mobile system,

b) Satellite based mobile system (Mini-MINMARSAT),

c) Cellular Mobile system

2.4 Data Communication Facility for its Application

Depending upon the intra-office IT datacommunication requirement [facilitating e-mail,tntrane~ ERP etc], high speed synch (n x 64 Kbps:V.35/E- 1, G.703) data channels or 10/100 BaseTethernet channels amongst all the manned/attendedstations may be provided as per WAN topology.

2.5-Plant ‘Communication System

Following types of intra-plant communication maybeprovided at critical pipeline manned location (that isCompressor/Booster/Receiving station) for facilitatingthe communication amongst office, control room, fieldarea, tire station, etc, suiting to the criticality of plantoperation: ,,

a) VHF Walkie-talkie system,

b) Paging system,

c) Public address system, and

d) EPABX system.

Depending upon the locations of usage of variouscommunication devices of above-mentioned systems,the intrinsically safe, explosion proof and weather prooftypes of the devices needs to be decided andaccordingly to be deployed.

2.6 Video Conferencing (Optional)

For efficient interactive communications, multi-partyvideo conferencing facility [ISDN-BRUIP based] maybe provided amongst corporate and pipeline ‘headquarters.

2.7 CCT-V System (Optional)

For monitoring of areas such as MOV(Motor OperatedValve) and watchman gate at unmanned)mannedlocations of pipeline, the CCTV cameras and IRilluminator and centralised video management andnetwork video recorder may be provided.
