 With the MSC "Napoli" remaining in one piece a first controlled explosion blew holes in the deck plating in order to expose the structural beams below using shaped charges with a second cutting punch charge timed 50 milliseconds later than the first.That job successfully exposed the beams, so more charges were planted across the beams which were ultimately severed.With only her deck plates on the main deck holding the vessel together around the bridge structure of the vessel, two tugs at either end of the ship tried to pull the ship apart.
