BTW this contains plans for flood control and stability calculations for a similar design to Concordia. It seems to generate as many questions as it answers. Perhaps the numerous 'partial watertight' compartments explain why it took so much time to sink? Why did the captain believe only two compartments were breached? Surely it wasn't holed again when run aground?
Integrated flooding and standard for stability and crises management
Subdivision length Ls is 315.67 m, which is the greatest projected length below deck 6, which also limits the damaged hull used in the calculations. Buoyant hull is extended up to bulkhead deck (deck 4). The limiting area for the reserve buoyancy is between decks 4 and 6 excluding aft mooring deck. The area of reserve buoyancy is partially watertight with defined openings (see figure below).
Definition of Watertight Compartments and Subdivision zones. The ship is divided into 22 watertight compartments below the bulkhead deck (deck 4). Above the bulkhead deck the spaces have been divided into partial watertight compartments. Partial watertight bulkheads are located above the transversal watertight bulkhead on bulkhead deck. Where partial watertight bulkheads are not installed straight above the watertight bulkhead the effectively watertight deck area has to be applied in accordance with regulation 17. Such watertight areas are located sides on deck 5 along the ship’s length
