  11. First Information on Cargo risksMonday 30th October, 10h00-18h00 Styrene monomer • Vapours heavier than air, eye and lung irritant, liable to produce temporary tainting of seafood (Marpol B) • Risk for salvage crew : possible explosion would the ship brake in two, possible neural damage from by vapours

  12. First Information on Cargo risksMonday 30th October, 10h00-18h00 Others • MEK : vapours heavier that air, very volatile, explosive when mixed with air, almost non toxic to marine life (Marpol III) • IPA : very flammable, volatile, almost non toxic to marine life (Marpol III) • IFO and Diesel : see Erika experience

  13. Databases Information on ProductsMonday 30th October, 8h30-12h00

  14. GESAMP Risk TableMonday 30th October, afternoon Group of Experts on the Scientific Aspects of Marine Pollution • Styrene : Bioaccumulable, rather toxic to biological resources, danger for man if breathed or in contact with skin, heavy impact on Environment • MEK : No risk on all points except minor impact on Environment • IPA : No risk on all points • Plus bunkers hazards (IFO and Diesel)

  15. First Drift PrevisionsMonday 30th October, 11 AM • Ship to be washed ashore on Côtes d’Armor or Guernesey during night of 31st October if not towed. • Risk of Cason scenario

  16. Captains prepare for TowingMonday 30th October, 10h00-11h30 • From Abeille Flandre Capt. Seiler calls for intervention team with chemical protection to connect the towline on Ievoli Sun • At Maritime Prefecture Capt. Claden interviews Ievoli Sun captain, first mate and first engineer

  20. Intervention TacticsMonday 30th October, 12h00-12h30 • Overflight of ship and buoyancy assessment • Winching of Capt. Claden with explosion meter, contamination assessment • Assessment of ship situation, winching of respiratory equipment, winching of team • Stern investigation, towing gear selection • Towline connection, ship safeguard, departure

  24. Ship Investigation and DepartureMonday 30th October, 16h50-18h00 • Overall tour of accessible ship areas (deck, castle, cargo control room) • Recovery of cargo computer and available documents • No evidence of cargo leak.

  28. A double hull recent European vessel (European crew) 3 chemicals (Styrene, Methyl-Ethyl-Ketone, Isopropylic Alcohol) + bunker The second activation of the POLMAR response plan in 11 months No visible pollution and no recovery at sea technique at hand Scene of a New PotentialCrisis is Set With :

  29. Ship and Cargo Salvage Failed • But a major potential catastrophe was avoided • Leaving a potential threat along a major navigation route, close to important fishing beds • And wreck investigations will soon show that further action remains possible

  30. Wreck investigation Vessel upturned, 3 breaches, 1 imploded tank, minor seeps, strong currents
