It's a week since cruise ship Costa Concordia struck a rock and capsized off the Tuscan coast of Italy.
It risks causing the country's worst environmental disaster in over two decades if the almost two and a half thousand tonnes of fuel leaks into the sea.
Recovery teams have pulled oil barriers around the ship to try and prevent a disaster should it occur.
The ship is shifting on an undersea ledge and could slide further, threatening plans to pump oil out.
However, salvage crews must wait until the search for survivors and bodies is called off before they can begin pumping the fuel.
Rescue teams have worked tirelessly searching through the wreck, but hopes of finding anyone alive have faded.
Giglio deputy mayor said he had faith in the rescue teams.

"We still have some days of calm weather in order to continue the search. We need to have respect for these bodies that are still onboard, therefore we have to understand this situation and do our utmost. We have the greatest faith in these rescue teams, there are people here of very great capacities and great professionalism."
Eleven people are known to have died, with 21 still unaccounted for.
