Indian Oil Corporation Ltd (IOCL), Belgaum in Karnataka, has an existing LPG bulk storage with 3 nos. above-ground bullets of 150 MT capacity each, and 2nos. of mounded bullets having a capacity of 1200 MT each of LPG, along with 2 Carousals, 8 Unloading bays and 4 loading bays, expanding the cylinder unloading area and loading area, to meet the growing demand of LPG bottling market.
The scope of work is to carry out QRA, HAZOP and ERDMP for IOCL- LPG Bottling Plant, Belgaum, Karnataka covering the different components and equipment’s associated with this facility.
The main purpose of QRA study is to assess the potential risk levels for personnel due to accidental release of hazardous materials from LOC scenarios of the facilities and to demonstrate that the individual risks lies within the acceptable region.
The Objectives of QRA are as follows:
- Identification of Hazards and Major Loss of Containment (LOC) events.
- To calculate physical damage and effects of failure case scenarios which include Estimation of Jet Fire, Pool Fire heat radiation distances, Flammable gas dispersion distances, BLEVE and overpressure explosion distances.
- To evaluate Failure Frequency.
- To estimate Potential Loss of Life by quantifying Societal Risk.
- Risk assessment is performed to confirm that risk can be reduced consistent with the ALARP principle according to the UK HSE risk acceptance criteria.
- Recommend risk reduction measures to ensure that all risks lie in ALARP or Acceptable region.
The objective of the HAZOP study is to assist in managing project risk through early identification of hazards and operability problems and to reduce the probability and consequences of an incident that would have a detrimental impact to the personnel, plant, asset and environment. The objective of this ERDMP is to identify emergencies which can arise during normal operations of IOCL-LPG Bottling Plant, Belgaum and recommend mitigation measures to reduce and eliminate the risk or disaster. These include developing plans for actions during disaster or emergencies and preparing responses that 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 with aim to retain the affected area to its original conditions.
