Hazard Analysis and Risk Assessment of LPG Installations and Emergency Planning Strategies

This project, funded by the European Union, focuses on hazard identification and risk assessment for LPG installations. Utilizing the HAZOP technique, we examine potential deviations such as flow issues and containment loss in tanks and pipelines. The project also outlines worst-case accident scenarios, including catastrophic failures and their domino effects on nearby populations. Furthermore, it emphasizes the importance of emergency planning actions and assesses the potential impact on local communities and transportation routes, aiming for enhanced safety and preparedness.

  2. LI LI PI • Hazard Identification (line from tank to pump) • HAZOP technique, examine deviations for : • NO FLOW, LESS FLOW • MORE TEMPERATURE • LOSS OF CONTAINEMENT LPG Tank V-1 V-2 P-2 Ομάδα HAZOP

  3. Hazard Identification(cont.), HAZOP form for use Ομάδα HAZOP

  4. LI LI PI • Accident scenarios • Define some worst-case scenarios for LPG installation LPG Road Tanker 20 tn 2 in, gas phase to other tanks, compressor LPG BEST S.A. LPG Tank 200 m3 LPG Tank 120 m3 2 in hose to other tanks Supply pipeline from refinery 6 in, liquid phase Ομάδα HAZOP

  5. Top event scenarios • Initial event : Catastrophic failure of 200 m3 LPG tank, complete top events in event tree Ομάδα HAZOP

  6. Risk analysis on consequence, Domino effects • Comment Domino effects from tanker BLEVE

  7. Risk analysis on consequence, effects to people

  8. Risk analysis on consequence, effects to people (cont.) • Tank BLEVE accident in LPG installation located within industrial park, close to village • Very severe effects : 1500 TDU, 3rd degree burns in more than 50% of exposed population • Severe effects : 450 TDU, 3rd degree burns in 1% of exposed population • Mild effects : 170 TDU, 1st degree burns at significant part of exposed population (TDU : (kW/m2)4/3. sec, be careful with units)

  9. Risk analysis on consequence, effects to people (cont.) • Comment on effects to population • Comment on access to site • Comment on effects to transportation routes • Consider emergency planning actions
