1 HNS & Shipping: R&D and Preparedness to incidents ITOPF Amsterdam Seminar Thursday 15th November 2012 J. Sjon Huisman Min for Infrastructure & Environment DG Rijkswaterstaat NoordZeeland 1

2 NL response arrangements Organisation Risk analysis EU classification of HNS Example of response NL response arrangements Organisation Policy: Min for I&M N d RWS Noordzee Operational Coordination: Director of NL CG Chemical advice: National Service (BOT mi) EU/MAR ICE project Response: RWS Noordzee Contractors (salvor) 2

3 Risk analysis Preparedness: MARIN 5 year interval review Shipping data; offshore data quantative outcome (likelihood of // years) analysis of transported goods likelihood of HNS involved Still focus on OIL Classification Discrimination of: b lk chemicals h i l bulk packaged goods (containers) Classification of behaviour evaporation, evaporation floating, floating dissolving, dissolving sinking and anything in between. 3

4 Challenges In any incident DATA COLLECTION Safe Sea Net (SSN, EU/EMSA) Port of destination or departure P&I club Bill of loading, cargo owners S l Salvage company What is the level of accuracy?? Examples Bodrum, 1978: 99 drums Nemagon washed over board. Stolt Busan,, 1979: ton Styrene threat of spontaneous y p polymerisation Sinbad, 1979: lost more than 50 cylinders carrying liqued chloride. Stanislaw Dubois, 1981, among other cargo 367 ton Calcium Carbide. Due to collision it took water and threat of explosion, acetylene gas. Dana Optima Optima, 1984: sunk and carried Dinoseb Anna Broere, 1988: (collided with Atlantic Compass), carried 550 ton Acrylonitrile. Andinet, 2003: three containers and 63 loose drums carrying arsenic pentoxide. 4

5 MV ANDINET At the roads to Bremerhaven Haverikommando The incident Sunday 21 December 2003; 15:00 lt C t i reports t loss l th t i Captain off three containers UN 6.1; UN 2902 Also reports sighting of yellowish substance. Position: Terschellingerbank traffic scheme Container list received within 3 hours. 5

6 Andinet 3 containers Terschellingerbank Traffic Separation Scheme ARSENIC PENTOXIDE GUARANTEED TECHNICAL DATA Type designation: Type C (CCA) Standard: AWPA type C manufactured to IS09002 Weight per steel drum (chemical only): 100 kg Weight h including l d steell drum: d +/ / 104 kg k Composition of CCA: Copper Oxide/Chromic Acid/ Arsenic Pentoxide Description: Concentrated paste (72% oxide activity) Arsenic Acid: 37 8% Chromic Acid: 34,5% 34 5% Copper Oxide 13,7% Proportions of actives: Arsenic u AS2O % Chrome as CrO3 34.2% Copper as CuO 13.32% 6

7 Action taken Ship owners hold liable for damage Survey required by owners or representatives Ultimatum; reply within 24 hours Environment Technical Advisory Team analyzed data: containers need to be located and removed substance toxic, total release: large area contaminated for several days. Survey and removal P&I followed up immediately S f db i l company Survey performed by commercial Containers located on December 30th 2003, close to reported position Water sampling in the area, indicated short jump in arsenic against background value of 1.9 µg/l 7

8 Water sampling Sampling fish: pp Application: Fish is towed through the water and flow of water is continuously sampled. Water sampling Rosette sampler Application: taking samples in the water column at various depths. 8

10 Removal of the containers Salvor Multraship successfully removed all three containers, 21 January the first container, container 26 January second and third one. Loss of product during removal operation Containers delivered in Rotterdam: Checked: several drums in each container leaking. g All leaking drums emptied into IBC, 60 drums pumped into IBC, precautionary measure Happiness/sorrow 30 December: All three containers (628 drums) located and later on safely brought ashore; minor leakage all drums considerably damaged 30 December: During unloading/repacking containers in Bremerhaven it was found: 50 drums emptied into the sea (2500 ltrs) another 63 drums are missing 10

11 Corrosion of drums Substance, arcenic pentoxide was used to study att sea floor: t d speed d off corrosion i off drums d fl chromium oxide lays chromium salt over the steel, protection of the steel Conclusion: in theory the drums are passive for corrosion due to reaction of chromium. Corrosion of drums However: drums are damaged damaged, steel is not undisturbed undisturbed in the environment, bended steel has small (hair) cracks on inside and outside. paint is cracked as well Conclusion: in theory corrosion could last as long as three years, but other factors influence the situation. No clear answer 11

12 Information to Fishery Objective: avoid contamination of personnel avoid contamination of fish indicate position of drums (empty or filled) Premium if a drum is found and removed 454, 454 Settlement for damages if a catch is lost max. 650, Sampling of fish Food and consumption authorities sampled fi h to t check h k on arsenic i fish AIS and fishery inspectorate monitored fishing activities in the area (despite the negative advice to fishermen) Especially flat fish was thoroughly analyzed analyzed, No values found causing alarm. 12

13 Track and search As of Friday 27th: ZIRFAEA to investigate: Green dots (about 60) Red dots (investigated > 150) Black dot: lost containers Good / bad P&I immediately responded and acted di l accordingly Product details known shortly after incident Limited loss of hazardous substance (leakage) Removal of three containers. 13

14 Good / bad Press: false interpretation of information misleading questions to members of parliament persistent in spreading misleading information also environmentalists spreading wrong information Discussion Role of the government: ll t tto actt or to t pay polluter quick response proportional measures Stowage g gguidelines 14

15 Conclusions Government (NLCG and RWS) in charge (organisation, contracting), ( i ti t ti ) Response equipment mainly oil related, Commercially available HNS responders, Chemical advice wide spread (MAR ICE; national organisation; organisation producer) producer), Co operation with shipowner/p&i.
