Quantitative Risk Assessment for HPCL- Ramagundam Depot, Telangana

Ramagundam depot of HPCL is situated 3 kilometers from Ramagundam Railway Station; 260kms (approx.) from Hyderabad airport. Considering vast demand of Petroleum products in different Districts of Telangana State e.g. Peddapalli, Mancherial, Adilabad, Karimnagar and Bhopalapally, HPCL commissioned Ramagundam Depot in the year 2005 to cater to the needs of various ROs and Depots in and around the area.

The Ramagundam Depot receives petroleum products e.g. MS, HSD and Ethanol through railway wagons from HPCL Vijayawada Terminal. Ethanol is mostly received through tank trucks. The products stored in the Depot are – MS, HSD & Ethanol.

Hindustan Petroleum Corporation Limited has awarded iFluids Engineering to carry out Quantitative Risk Assessment (QRA) study for the Ramagundam-HPCL depot facility in Telengana.

The main objective of this QRA study is to determine the risk from process hazards associated with the Ramagundam-HPCL depot.  The study quantified the risk ranking in accordance with the severity and probability. In order to meet the objective of the assessment, potential scenarios have been identified, evaluated and the chances of consequences related to potential accidental releases occurring in the facility were exhibited. The QRA study was carried out with the following objectives:

  • To discover the Major Hazards and Loss of Containment (LOC) scenarios
  • To compute the physical effects of failure case scenarios which includes Estimation of fire results such as Jet Fire, Pool Fire and Flash Fire alongside with Overpressure Explosion.
  • To assess the failure frequency of the facility.
  • To determine the societal risk and to estimate the Potential loss of Life.
  • To perform a risk assessment to confirm that the risk mitigation can be consistent with the ALARP principle according to the UK HSE risk acceptance criteria
  • To recommend risk reducing measures to make sure that all risks are in ALARP or in Acceptable region

The QRA study results provided recommendations for risk reduction measures to ensure all computed risks are in ALARP or the Acceptable Region, which were reviewed and accepted by HPCL.
