Franco Gabrielli, head of the Civil Protection Department stated on Sunday: "Righting the 1st window of the sunken cruise ship Costa Concordia is 16th of September." The third phase of the wreck removal of Costa Concordia is parbuckling.
Depending on the weather conditions, all scheduled phases of the wreck removal of the sunken ship must be finished be the end of September.
Parbuckling project is consisted of 5 main phases:
1. Stabilization of the Costa Concordia wreck
Stabilization and anchoring of the sunken cruise ship Costa Concordia's wreck is the 1st phase, which aims to avoid any sinking or slipping of the vessel. The major aim of the stabilization phase is to provide safety to workers engaged in the removal process.
2. Submarine supports and portside caissons installation
Wreck resting is being scheduled for the 2nd stage of the parbuckling project, In this phase will be prepared the false bottom so the wreck can rest after its rotation.
3. Parbuckling of the sunken ship's wreck
The rotation of the cruise ship's wreck or parbuckling process scheduled to long a few days, as the entire movement must be highly delicate and steadily observed.
Strand jacks are scheduled to be used to tighten some cables, attached to the top of the platfomrs and to the caissons. They are going to be pulled seaward in the parbuckling process, while the attached cables to the Costa Concordia's starboard turrets are going to be used for balancing the cruise ship's wreck.
The parbuckling process is one the of most delicated phases in the entire project, during which must be carefully offset the forces involved in the operation to rotate the sunken cruise ship's wreck avoiding any risk of deforming the hull of the Costa Concordia.
4. Starboard side installation of caissons
Additional fifteen refloating sponsons are scheduled to be attached to the starboard of the sunken cruise ship, which will ease the refloating of the vessel's wreck.
5. Re-floating of the sunken cruise ship's wreck
Consequently to the previous phases of the removal operation, the hull must be resting on the bottom's false at 30-meters depth. The water will be gradually pumped from the wreck caissons with a pneumatic system, which will provide enough push upwards. After completion of all removal phases, a section long 18-meters is scheduled to remain submerged.
