This course will help you to develop the skills and knowledge to identify, assess and communicate process risks from a safety, environmental or business perspective, from a simple qualitative approach to fully quantified assessments.

Learning outcomes

By the end of the course you will understand:

  • the concepts of individual and societal risk 
  • risk tolerability
  • the 5-stage risk assessment process, the different types of process risk assessment and when to apply them
  • techniques for qualitative, semi-quantitative and quantified risk assessment (QRA) including risk matrices, bow tie analysis, LOPA, occupied buildings risk assessment and fault tree/event tree analysis (FTA and ETA)
  • environmental risk assessment using a risk matrix-based approach (CDOIF methodology)
  • the principles of ALARP demonstration.

Who will benefit

  • staff involved in the risk assessment process including supervisors, managers and directors 
  • plant/process operators including maintenance functions 
  • process safety engineers and loss prevention specialists 
  • chemical engineers working toward Chartered status.

Helen Fennell graduated in Chemical Engineering from Loughborough University in 1997. Since then she has had roles across Operations, Design, Commissioning and Process safety, including senior technical authority roles in Process Safety Management. She has worked across diverse industries including utility systems, onshore and offshore oil and gas facilities, reforming, high hazard installations, cryogenics and novel processes.

Helen has a proven track record of delivering engineering solutions to ensure risks on both greenfield and brownfield projects are ALARP against a backdrop of aggressive schedules and regulatory compliance criteria. Project values range from US$20 Billion down to small discrete studies for operating facilities.

In 2014, Helen set up Inherent Safety Consulting Limited to provide specialist process safety services including process safety studies and hazard review chairmanship. She is an experienced hazard review chairman with over 80 hazard reviews chaired, including What-If, HAZID/ENVID, HAZOP, SIL, LOPA, ALARP, SIMOPS and WEHRA.
