HAZOP & Quantitative Risk Assessment for HPCL-Kurnool ASF, Andhra Pradesh

The Hindustan Petroleum Corporation Limited, incorporated as a company under the Indian Companies Act of 1913, is a Forbes 2000 and Global Fortune 500 Company. HP Aviation refueling facilities known as ASFs, have been excelling in providing reliable, safe, and quality service to airlines. 

The Kurnool ASF was commissioned in March 2022 at Kurnool Airport, Orvakal, Andhra Pradesh. There is no manufacturing process involved in Kurnool ASF. There are 2 Refueler Trucks in Airport used for refueling Alliance Air flights and the overall storage capacity of the facility is 30KL of ATF.

Hindustan Petroleum Corporation Limited has awarded iFluids Engineering to carry out HAZOP study for the Kurnool ASF, Andhra Pradesh. This study covers the different sections, components, and equipment associated with this facility.

The main objective of the HAZOP (Hazard & Operability) study is to aid 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 on the personnel, plant, properties, and environment.

The Objectives of HAZOP are as follows:

  1. Identify the hazards inherent to the facility/process.
  2. Identify the credible manual with/or equipment instrument failures likely to lead to accident scenarios/hazards/operability problems.
  3. Qualitatively assess the risk(L/M/H/S) and provide recommendations to prevent/overcome the hazards if required.
  4. In addition to these issues, HAZOP occasionally identifies items that could improve unit operations and the efficiency of the process.

Hindustan Petroleum Corporation Limited has awarded iFluids Engineering to carry out Quantitative risk assessment study for the Kurnool ASF, Andhra Pradesh, which covers the different components and equipment associated with this facility only.

The main objective of this study is to evaluate the potential risk levels for personnel due to accidental release of hazardous materials from loss of containment scenarios from the facilities and to demonstrate that individual risks are within the broadly acceptable regions.

The Objectives of QRA are as follows:

  • To Identify Hazards and Major Loss of Containment(LOC) events.
  • To Calculate physical effects of failure case scenarios that include Estimation of Jet Fire, Pool Fire heat radiation distances, Flammable gas dispersion distances, BLEVE and overpressure explosion distances.
  • Failure Frequency evaluation.
  • To quantify Societal risk and estimate Potential Loss of Life.
  • To Perform a risk assessment to confirm that the risk can be reduced consistent with the ALARP principle according to the UK HSE risk acceptance criteria.
  • Recommend risk-reducing measures to ensure that all risks are in ALARP or Acceptable region.
