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

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
- 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.
