HAZard OPerability Study for the facilities related to Four LPG Pipeline

Indian Oil Corporation Limited (IOCL) has an Independent LPG Pipeline between

  1. Haldia and Durgapur with Dedicated Pumping Facilities at Haldia and Associated Facilities at Durgapur Station [PHDPL AUG]
  2. Paradip Somnathpur Haldia Pipeline [PSHPL]
  3. Haldia-Barauni Pipeline in Haldia-Barauni Section of PHBPL [HBPL]
  4. Ennore – Thiruvallur – Bengaluru – Puducherry – Nagapattinam – Madurai – Tuticorin (ETBPNMTPL) Natural Gas Pipeline


    • The proposed project of pipeline for “Independent LPG pipeline between Haldia and Durgapur with dedicated pumping facilities at Haldia and associated facilities at Durgapur Station” has been designed with following details:
    • Length: 279.5 km (West Bengal),  Pipe size: 18” OD,  Capacity: 3.5 MMTPA,  Pipeline would be laid normally at about 1.2 to 1.5 below surface level.
    • Laying 344 km (approx.) long, 18” OD x 0.25” WT, API 5L-X70 grade pipeline from Paradip in Odisha to Haldia in West Bengal.
    •  Originating pumping station at Paradip with 3 (2+1) motor-driven mainline pumping units (MLPUs) of adequate capacity.
    •  Delivery facilities at Somnathpur along with scraper receiving and launching facilities.
    •  Pipeline to terminate at the newly acquired land adjacent to existing PHBPL crude pipeline installation and hooking up with 18” dia proposed Haldia-Barauni Pipeline.
  • HBPL
    • Haldia Barauni Pipeline Project involves laying a 30” OD crude oil pipeline from Haldia to Barauni with an IPS at Bolpur. Hydraulics details have been worked out for the proposed 30” crude oil pipeline scheme from Haldia to Barauni along with hydraulic details of 18 inch mainline and loopline of existing Haldia-Barauni section of PHBPL to product and gas service respectively.
    • The pipeline system has been designed for transportation of R-LNG. Following pipeline sizes have been selected for the pipeline based on PDI (Population density index) Class-I, II, III and IV

The objective of the HAZOP (Hazard & Operability) study is to aid in managing project risk through early identification of hazards and operability problems of the combined pipelines running across the country and to reduce the probability and consequences of an incident that would have a detrimental impact to the personnel, plant, properties and environment.
