Process Hazard Analysis (PHA)

Prosaris has extensive experience in the facilitation and management of Process Hazard Analysis (PHA) techniques and for assessing and applying the most appropriate methodology. We have managed and facilitated PHA studies for onshore and offshore oil and gas facilities, large scale mining projects, and particularly excel at PHA studies in support of operational changes and complex operating challenges.

Our onshore and offshore operations experience, strong process safety background, and experience in the facilitation of PHA sessions means that we manage and facilitate the PHA sessions while adding significant value to the process and operational experience. This ensures that the solutions proposed to identify risks are effective, achievable, and mindful of operational constraints. We are experienced in the development of PHA policies and procedures including risk matrix guidance and MOC process flow support in the determination of appropriate PHA tools for identified changes.

We support the process, planning, and completion of PHA revalidation studies. The PHA techniques and services that we offer include:

  • LOPA
  • Bow-Tie Analysis
  • Fault Tree Analysis
  • Event Tree Analysis
