A shipping company is mounting the biggest maritime salvage operation ever — to right the Costa Concordia cruise ship and the firm's reputation.

Susan Ormiston takes a tour with the salvage master.

The 290-metre ship ran aground and capsized off Italy's Tuscan coast in January. Of the 4,200 people aboard at the time, 32 were killed. 

A hearing in the Tuscan city of Grosseto began earlier this week to determine if Francesco Schettino, the ship's captain, will face charges.

Schettino is accused of manslaughter, causing the shipwreck and abandoning the ship while passengers and crew were still aboard. He has denied the accusations and has not been charged.

If Schettino goes to trial, it will not likely begin before 2013.
