15
First Drift Previsions Monday 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

Towline Connection Monday 30th October, 16h00-16h50 Waves 8-9 m. Stern deck small. No hydraulics available. Decision : hoist light gear by hand and pull towline gear from Abeilles Flandre Success at second attempt (16h50) Expecting return of Super Frelon
24
Ship Investigation and Departure Monday 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. Evidence of work on hydraulics (leak of hydraulic oil). 18h00 : departure after closing castle door (bad condition, 3 men needed)
25
Towing Underway Monday 30th October, from 14h50 East-North- East, 4 knots Toward Cherbourg port or stranding in Cotentin shelter
26
Towing underway
27
Ievoli Sun Sinks 3/4 of Way Tuesday 31st October, 9h30 9 NM North- West of Aurigny island (British Isles) 20 NM from cape of La Hague (France)
28
Scene of a New Potential Crisis is Set With : 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
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
