HAZOP, QRA and ERDMP for IOCL- Mughalsarai Terminal

IOCL-Mughalsarai Marketing Terminal which was commissioned on 01 Oct 1966, receives BS VI Petroleum products such as Motor Spirit(MS) and High Speed Diesel(HSD) through Pipeline from Barauni Refinery. These products are stored in Mild Steel storage tanks constructed for respective Petroleum products and distributed to retail outlets through tank trucks. The terminal is spread over a plot area of approx., 32 acres. The terminal receives Ethanol from Road Tank Trucks and stores it in Underground and Above Ground Storage Tank. The terminal also has product pumping facilities to neighbouring installations of HPCL and BPCL through dedicated transfer pipeline and Multilevel Flow Modellig(MFM).

The facility provide with receipt, storage and dispatch of petroleum products. Operations at site do not involve any chemical or physical processing.

It is engaged in receiving petroleum products viz. Motor Spirit (MS) and High Speed Diesel (HSD) through pipelines, Ethanol receipt through Tank Trucks (TTs). Petroleum products from receipt manifold sent to their specified storage tanks. And dispatch of Motor Spirit (MS), Ethanol and High Speed Diesel (HSD) by Road Tankers.

The scope of work is to carry out QRA, HAZOP and ERDMP for IOCL-Mughalsarai Terminal, Uttar Pradesh and the study covers the different components and equipment’s associated with the existing facility.

The main purpose of QRA study is to assess the potential risk levels for personnel due to accidental release of hazardous materials from Loss of Containment (LOC) scenarios from the facilities and to exhibit that individual risks lie within the acceptable region.

The Objectives of QRA are as follows:

  • To identify hazards and major Loss of Containment (LOC) events.
  • To evaluate physical damage and effects of failure case scenarios that includes estimation of jet fire, pool fire, heat radiation distances, flammable gas dispersion distances, BLEVE and overpressure explosion distances.
  • To evaluate Failure Frequency.
  • To estimate societal risk and potential loss of life.
  • To perform risk assessment to ensure that risk can be reduced in consistence with ALARP principle based on UK HSE risk acceptance criteria.
  • To recommend risk reduction measures to ensure that all risks lie in ALARP or Acceptable region.

The main objective of HAZOP study is to aid in managing project risk through early identification of hazards & operability problems and to reduce the probability and consequences of an incident that would have a detrimental impact on the personnel, plant, properties and environment.

The objective of ERDMP Study is to identify emergencies that occur during normal operations of IOCL-Mughalsarai Terminal and recommend mitigation measures to reduce and eradicate the risk or disaster, develop plans for actions during disaster or emergencies and keep prepared responses to mobilize the necessary emergency services including responders (primary, secondary and tertiary) like Fire service, Police service, Medical service including Ambulance, Government and Non-Governmental agencies. This also includes post disaster recovery to retain the affected area to its original conditions.
