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

Qualitative analysis of the likelihood of HNS spills

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

Categorisation of HNS No one overall system IMDG Code GESAMP ARCOPOL

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

Header Rotterdam Bulk Goods: IMDG

Header Antwerp Bulk and Packaged Goods: IMDG

Header Bulk HNS by IMDG Code

Header Antwerp Bulk and Packaged goods by IMDG

Header 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

Header Vessels carrying bulk and packed goods: Antwerp

Header Qualitative Analysis

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

Header 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.

Geographical Distribution: Bulk IMDG 1-9

Packed goods IMDG 1-9 Antwerp

Packed Goods: ARCOPOL Top 20

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

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
