Only imagine it's a supertanker full of diluted bitumen wrecked off the proposed tanker port of Kitimat. Okay, there are differences. This is a cruise ship, fairly benign as wrecks go. The supertanker would be disgorging tons of diluted bitumen, dilbit, full of acids, heavy metals and other toxins. Another difference is that you wouldn't see the supertanker, not for long, because the rocky bottom around the port site can lie 600 feet down where there'd be no effective means to clean up the disaster.
Like all forms of modern mass transport, cruise liners are utterly dependent on complex electronic devices to steer them – and on electricity to run these systems. Without power, a ship is stricken and with reports suggesting that an explosion occurred in Concordia's engine room shortly before the ship ran aground, early analysis indicates power loss is likely to have been a key factor in the accident.
With Harper's Kitimat supertanker port it's not a matter of if, it's only a question of when.
