Process Safety

Jill Wilday is a chemical engineer with a background in risk assessment,  process safety and chemical industry operations.  She is now the Process Engineering Team Leader, having originally come to HSL from ICI. Jill leads HSL's involvement in assessing predictive and technical aspects of COMAH Safety Reports on behalf of HSE and also has experience of assessing the fire, explosion and Quantitative Risk Assessment (QRA) aspects of offshore safety cases.

She has strong links to academia and was responsible for the introduction of the MSc course in Process Safety and Loss Prevention at Sheffield University. 

Jill holds Chartered Engineer (CEng) status and is a Fellow of the Institution of Chemical Engineers (FIChemE). In 1990 she was awarded the Hutchinson Medal by the IChemE. 

Jill's current research interests include:

- major hazards risk assessment, including emergency planning and emergency response. Jill leads projects for HSE developing onshore societal risk methodologies and land-use planning methodologies.

- consequence modelling and the use of software such as DNV PHAST, Shell FRED/Shepherd/LPGLite and HSE software.

- COMAH. Jill leads HSL's support to HSE on COMAH assessment and related inspection activities, and is involved in COMAH predictive, occupied buildings risk assessment (OBRA) as well as other process safety assessment work.

- offshore safety. Offshore safety case assessments for fire, explosion and quantitative risk assessment.

- pressure relief system sizing, including two-phase flow. Validation of sizing methodologies for runaway reactions and tube failure in shell-and-tube heat exchangers.

- hydrogen safety.  Particularly as it relates to the nuclear sector, including inherent safety/optioneering studies for highly active waste storage.
