Target

Design and implementation of telecommunication and SCADA  systems, to centrally supervise and facilitate effective, reliable and safe operation of a WEP ’s branch pipeline, starting in Piyazabad ,  having a length of 150 Km, 4 BV s, 1 L/R , and conducting ethylene to Ilam petrochemical plant. It can be supervised in both main pipeline’s CCRs  and Piyazabad’s LCR .

Main Features

• A part of a first priority national project
• Integrating various telecom systems in order to meet voice, data, safety data and video conference requirements of the pipeline
• Integrating supervisory monitoring, safety systems, and telecom backbone systems
• Integrating the whole SCADA and telecommunication system with the main ethylene pipeline’s
• Different geoclimatic factors in project execution

Scope of Work

• Telecommunication systems
  • SDH fiber optic transmission system along the pipeline
  • PCM access equipment
  • Synchronization equipment
  • SDH and PCM network management systems
  • Usage of fiber optic cable (the backbone of the telecommunication network) to provide data network to transmit pipeline PCS/DCS/ESD data from the RTUs and ESDs located on the LBV stations to central stations and compressor stations
  • VHF/UHF radio coverage along the pipeline
  • SDH microwave radio links, proposed as an option to the client providing more data path protection in spite of 1+1 protected state of the SDH equipment
  • UHF/VHF analog trunk radio coverage system to enable mobile communication along the pipeline and between the pipeline mobiles and central control rooms (CCRs) as well as local control rooms (LCRs)
  • Hotline telephone and emergency call system
  • PABX and hotline telephone system to provide direct access voice and data between the main control rooms and each compressor station, valve station, and metering and pressure regulating station. Besides, point-to-point MW radios are recommended as optional communication paths.
• Control systems
  • Data gathering systems (RTUs), installed in metering and pressure regulating stations, compressor stations, LBV s and L/R  stations
  • SIL-3 safety system for pipeline ESD , requiring a separate Ethernet over fiber optic path -provided using industrialized switches- for conveying safety information and commands
  • A two-layer SCADA system having 3 MCCs  and 8 LCCs   , where information from all RTUs along the pipeline is sent to the local and main control centers for processing using SCADA, ESD , and LDS  software
  • Usage of fiber optic cable as the media to transmit pipeline’s SCADA data including leak detection and pipeline safety data
• Civil work
  • Construction of 5 telecom buildings in block valve stations
  • Foundation laying and installation of telecom towers
  • Implementation of grounding and lightning protection systems
