Categorisation of HNS
• No one overall system
• IMDG Code• GESAMP• ARCOPOL
![Page 5: BE-AWARE I HNS Risk Assessment Bonn Agreement: Area-wide Assessment of Risk Evaluations Co-financed by the EU – Civil Protection Financial Instrument](https://reader036.vdocuments.net/reader036/viewer/2022062804/5697bfa01a28abf838c9566f/html5/thumbnails/5.jpg)
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

HeaderHeaderRisk 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
![Page 14: BE-AWARE I HNS Risk Assessment Bonn Agreement: Area-wide Assessment of Risk Evaluations Co-financed by the EU – Civil Protection Financial Instrument](https://reader036.vdocuments.net/reader036/viewer/2022062804/5697bfa01a28abf838c9566f/html5/thumbnails/14.jpg)
HeaderHeaderRisk 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.

• 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.
Future work on HNS analysis
![Page 19: BE-AWARE I HNS Risk Assessment Bonn Agreement: Area-wide Assessment of Risk Evaluations Co-financed by the EU – Civil Protection Financial Instrument](https://reader036.vdocuments.net/reader036/viewer/2022062804/5697bfa01a28abf838c9566f/html5/thumbnails/19.jpg)
• 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 behaviour of HNS spilt at sea.• Develop web-based decision-support tool
