BE-AWARE I HNS Risk Assessment

This project involves a comprehensive risk assessment of accidental spills of Hazardous and Noxious Substances (HNS) in port operations. Using data analysis, accident modeling, and qualitative analysis, the project aims to improve safety measures and response strategies for potential HNS incidents.

  1. BE-AWARE I HNS Risk Assessment Bonn Agreement: Area-wide Assessment of Risk Evaluations Co-financed by the EU – Civil Protection Financial Instrument

  2. Qualitative analysis of the likelihood of HNS spills

  3. Accident models DATA Collection Data Collection and Analysis • Rotterdam (Bulk) • Antwerp (Bulk & Packed goods)

  4. No one overall system IMDG Code GESAMP ARCOPOL Categorisation of HNS

  5. Methodology • Top 100 most transported goods (bulk and packed) • Each dataset divided into IMDG, GESAMP and ACROPOL • SAMSON accident database used to estimate accidents of HNS shipments or vessels per cell

  6. Rotterdam Bulk Goods: IMDG

  7. Antwerp Bulk and Packaged Goods: IMDG

  8. Bulk HNS by IMDG Code

  9. Antwerp Bulk and Packaged goods by IMDG

  10. Top 100 Substances transported Totals for both ports • ARCPOL substances are evenly spread between packaged and bulk shipments • GESAMP substances are mostly found in packaged goods

  11. Vessels carrying bulk and packed goods: Antwerp

  12. Qualitative Analysis • Involvement of IMDG classified substances in collisions • Involvement of TOP 20 ARCOPOL classified substances involved in collisions • Involvement of chemical class I and II tankers in collisions

  13. Risk analyses for bulk goods • 1 collision a year with vessel carrying IMDG 1-9, approx. 2200 tonnes of HNS involved • 1 collision in 3 years with Class I or II tanker with approx. 3000 tonnes of involved • 1 collision in 10 Years with vessel carrying ACROPOL Top 20 substance with 90 tonnes involved

  14. Risk Analysis for packed goods • 0.8 collisions per year that involve a vessel with HNS on board as packed goods • The total amount of HNS involved in a collision is 843 tonnes per year, which would include 4 different HNS shipments.

  15. Geographical Distribution: Bulk IMDG 1-9

  16. Packed goods IMDG 1-9 Antwerp

  17. Packed Goods: ARCOPOL Top 20

  18. Future work on HNS analysis • Improvement of databases to hold HNS shipment data including standard names and UN no. • Development of a categorisation system covering all substances • Development of a model that can analyse the amount of HNS spilled for accidents involving product tankers with many different cargoes • Development of a model of the effect of a collision on containers in different parts of a vessel and the likelihood containers would be lost following a collision • Develop more detailed model of the fate and behaviour of HNS spilt in accidents.

  19. improve the understanding of the behaviour of HNS spilt at sea; • conduct lab experiments to further document the physico-chemical properties of commonly transported HNS • produce environmental and socioeconomic sensitivity maps dedicated to HNS; • develop a 3D mathematical model that can forecast the drift, fate and behaviourof HNS spilt at sea. • Develop web-based decision-support tool
