The company that owns the Costa Concordia has announced new safety measures four months after the cruise liner capsized off the Italian coast.
They include the introduction of real-time tracking of a ship's route and new procedures ensuring that not only the captain but also other officers take part in crucial navigation decisions.
Prosecutors have accused the captain of causing the capsize near the island of Giglio off the coast of Tuscany on 13 January, in which 30 passengers died.
