Grounding of the Costa Concordia

Information http://www.qps.nl/display/qastor/2012/01/17/20120117_stranding: After the Costa Concordia made the headlines by running onto a rock off the island of Giglio in Italy, we've received many questions whether this could have been prevented. Now we can't tell what happened exactly on the bridge of the Costa Concordia the night of the grounding, but we have made a small reconstruction based on the AIS data. We used our Qastor Pilotage software to replay the final minutes of the Costa Concordia and show the sort of warnings that are available to the mariner in today's software.

Yes, I absolutely agree, my comparison was just about the stupidity of the captain/pilot and about that they play with the life of other people (if them are in the ship or outside the airplane is not so important), they are both playing where e when you can't play.

In both cases their are still alive, unfortunately.

@Onosk While I agree some similarities excist (cockyness by the captain/pilot), I do not believe these cases are that similar. The aircraft was flying lower than allowed, but at least that particular aircraft is supposed to fly low during operational missions. Playing chicken with rocky shallows with a cruiseship carrying 4000 people is something else entirely.

Look at the two rocks named "Isole Le Scole", at 0:53. The "game" was to "drive" between them as, it seems, a few times it already happened.

There is a good article about this, only in Italian and not verified, but with a lot of sense:

Go to abruzzo24ore dot tv and search for "costa concordia dove voleva passare schettino"

Why?

Do you remember the disaster here in Italy in Cermis?

Look en wikipedia for "cavalese cable car disaster 1998".

There is not a "why" with any sense for this, and I think this case it's very similar.

@sushimoustache If we take the plot on this clip at face value, I would think that it's quite obvious when & where, to be honest. The bow missed the rock, the rear went wide (which is what I would expect), and hit the rock. The plot actually shows the ship bouncing off. This is consistent with the damage shown so far, the bow (and stabiliser) missing, and a big hole with a rock lodged in it after that.

I think the main question here is "why?"

....Al minuto 1:32, probabilmente ormai ingovernabile, decidono di dare ancora.

Al minuto 2:08 la catena va in tensione, la fa ruotare e, mentre si posa sul fondo, la fa riavvicinare all'ancora.

Qualsiasi imbarcazione alla deriva tende sempre a posizionarsi al traverso del vento.

La velocità di deriva verso la costa di 0,6/0,7 nodi (poco più di 1 km/h) è compatibile con la corrente e/o una leggera brezza.

@DoktorVallu ti do il mio parere, per quello che vale.

L'impatto avviene al minuto 0:57, si vede il SOG (velocità rispetto al fondo maino) scendere bruscamente e per effetto dell'urto nella metà poppiera si vede la nave ruotare a sinistra.

Sui media hanno riportato che il timone è stato trovato bloccato dall'urto completamente girato a dritta, al minuto 1:17 la nave, mentre rallenta, riprende a ruotare appunto verso dritta....

The hard turn to Starboard after the impact with the rock at the Port stern quarter appeared to be a maneuver to slow the vessels speed down. Turning the ship broadside to its forward motion in the water would slow the vessel down quickly. The speed of the ship slowed to around 1 knot and then it appeared to employ a Port side bow thruster to maneuver her bow towards the island. Then it seemed that she was moved by wind and current towards shore. The ship had too much speed (15+ knots) befo

@Rainchasersailing

I still don't have a clear picture of when the ship struck or where it hit, but after reading a collection of essays called "Cathedral of the World" I came to understand that one should never expect a clear area on a chart means it is actually clear. Unless you are in a channel, there is little guarantee that a surveyed area has been exhaustively checked. Every chart is a synopsis of reality, and unless you are in a channel you should proceed advisedly.

@DoktorVallu It could have been a lucky sea current or could have used the bow thruster or thrusters (look in google images). Propellers are generally used for maneuvering in port or at least help the movement of the bow.
