Quantitative Risk Assessment (QRA)

Quantitative Risk Assessment (QRA)


Velosi is having a global multidisciplinary team of QRA experts with vast experience for carrying out QRA, Occupied Building Risk Assessment (OBRA), Process Safety Reviews/audits, particularly in explosion prevention & protection. We offer a full scope of QRA studies for Oil & Gas upstream & downstream facilities, Petrochemicals, pipelines, wellheads & storage terminals etc. in order to meet our client’s needs. We provide the process industry with the expertise and resources to understand the hazards and risks in any petrochemical facility or operation.

The QRA evaluates both the likelihood and impact of an unplanned event and allows a business decision to be made on the most cost-effective risk reduction solutions, where necessary. Effectively managing risk results in cost savings by reducing business interruption, limiting injury to people and damage to equipment.

A QRA is an essential tool to manage your process risks & improve your process safety performance.

The purpose of a QRA study is;

  • To assess the risks to personnel, assets, and production posed by the facilities & determine their significance. This will help to decide how best the risks can be reduced
  • To identify, quantify and assess the risk to nearby facilities / installations.
  • To determine the acceptability of the calculated risk at the facilities and identification of the key risk contributors
  • Develop LSIR contours to be used for land use planning
  • Represent risk from all critical wellheads and pipelines to establish effective risk reduction measures and emergency response.
  • To provide clear and unambiguous recommendations for risk reduction where necessary to ensure that the risks are controlled within acceptable limits
