So what DID cause the Costa Concordia to hit the rocks? Human error, electrical failure and uncharted ridge are all theories

There's a scene in the disaster movie The Towering Inferno in which Steve McQueen’s fire chief rails against architects for building office blocks higher and higher with scant regard for public safety.
So what would he have made of the gigantic, floating hotels that pass for modern cruise liners? In the past decade, the size of the passenger ships cruising the world’s oceans has doubled.
The biggest of these monsters weigh more than 225,000 tons and carry more than 6,000 passengers.
Even the Costa Concordia is no minnow. As the 26th largest passenger ship in the world, its 13 passenger decks are stacked on a vessel nearly 1,000 ft long and 100ft high above the water. When it set sail from Italy on Friday, it resembled a floating office block, rather than a conventional ship.
For years, there have been concerns within the shipping industry that these ocean-going behemoths are too big, that their crews are poorly trained and that their officers are too reliant on electronic navigation aids.
Crucially experts have warned that the construction and safety standards in place for modern cruise ships were designed for vessels half their size. So how did the Costa Concordia come to capsize within yards of the shore? Last night there were at least three conflicting theories about what happened.
What is certain is that, soon after the voyage began, passengers heard a bang and the ship was plunged into darkness. The first theory is based on the captain’s account of events – that he hit an uncharted rock and reacted by bringing the vessel into safer shallow waters off the island of Giglio. There it was damaged again on rocks and rolled on to its side.
Under International Maritime Organisation rules, captains are supposed to use the ship itself as a ‘lifeboat’ and return to port for evacuation.
The second is that there was a massive electrical failure which affected the ship’s navigation equipment, or a computer failure that sent the navigation systems haywire causing it to go too close to shore where it hit the rocks.
A third theory is that it was old-fashioned human error – or even recklessness – that allowed the vessel to ground in shallow waters. The investigation will look into every decision, order and event that led up to the sinking and will take months to come to a conclusion. On paper, human error remains the prime suspect.
It is the main cause of 80 per cent of shipping accidents and the crew may simply have become distracted or lost concentration early on in the voyage, allowing the vessel to drift to the coast.
