In Saint-Nazaire, the ship exchanges the fuselage sections from Hamburg for larger, assembled sections, some of which include the nose. This ship unloads in Bordeaux. It then goes to pick up the belly and tail sections from Construcciones Aeronáuticas SA in Cádiz, Spain, and delivers them to Bordeaux. From there, the A380 parts are transported by barge to Langon, and by oversize road convoys to the assembly hall in Toulouse. To avoid damage from direct handling, parts are secured in custom jigs carried on self-powered wheeled vehicles.
