Rome ( CNN ) -- Rescuers searching the stricken Costa Concordia found a body on bridge 3 Tuesday , bringing the number of confirmed dead from the wreck to 16 , civil protection officials said . The discovery leaves about 16 people still missing from among the roughly 4,200 aboard the cruise liner -- about 3,200 passengers and 1,000 crew members -- at the time of the collision with rocks off the island of Giglio . The vast majority fled the ship safely , if under chaotic and frightening conditions , according to survivors . Undersea salvage experts will not start siphoning fuel off the partially sunken liner before Saturday , the man in charge of the operation said Tuesday . Teams of divers have begun to set up the operation , Franco Gabrielli said in remarks televised from Giglio . His comments appear to contradict a timetable laid out Monday by an Italian admiral , who said that salvage workers were to begin pumping fuel out of the liner that day . Adm. Ilarione Dell'Anna said it would take 28 working days to remove all the fuel from the ship . Gabrielli did not explain the discrepancy . He has asked the company that owns the ship to come up with a plan to clean up pollution from the vessel , such as garbage , by Wednesday , he said . The search for survivors and victims will continue alongside the salvage , said Gabrielli . The man in charge of the rescue operation said the divers faced a grim task . `` Imagine that you left for holidays and that the power went off in your house . What would you find in your fridge ? The divers are in there , '' Ennio Aquilino said . Two bodies were found on Monday , and two more over the weekend -- one woman on Saturday and one on Sunday , both wearing life jackets . Divers used explosives Monday morning to blow more holes in the side of the ship to allow easier access . The parties involved in the rescue told reporters and residents on the island Sunday that search and rescue efforts will continue -- but that the environmental risk is also becoming urgent . Officials said they can not predict how long it will take to clear the wreckage , since that depends on maritime conditions and technical difficulties , but all legal , environmental and human factors will be taken into account . `` It 's time for Italy to show it can do something right and do it well , '' said Gabrielli . He warned that the task ahead was complicated and daunting , not least because it takes about 45 minutes to search each cabin , using special cameras and divers . The giant Costa Concordia had 1,500 cabins on board . A class-action lawsuit will be filed in Miami against Costa and its parent company , Carnival Corp. , the Italian consumer group Codacons said Saturday . The suit , in collaboration with two U.S. law firms , is `` aimed specifically at getting compensation for all damages to the boat passengers , '' Codacons said in a statement . The class-action suit is open to passengers of any nationality , it said . `` We 've been contacted by hundreds of victims and the numbers are growing moment by moment , '' said Mitchell Proner , senior partner at Proner & Proner , one of two firms involved . He said crew members have also contacted the firm , `` and their stories that are coming in are horrific -- from lifeboats that were stuck halfway , passengers debating whether to jump or not . This was not an orderly evacuation . '' The suit , he said , will request at least 125,000 euros ( about $ 160,000 ) per passenger . The suit has not yet been filed , said Marc Bern , senior partner at the other firm , Napoli Bern Ripka Shkolnik , but `` it will probably be in the billions of euros and dollars . '' `` The sheer terror of being on a ship of that magnitude going down , you can imagine the psychological damage , '' Bern said . Meanwhile , Gabrielli said no fuel oil had yet leaked from the ship -- only kitchen and engine oil -- and that he did not see an immediate risk of the 2,400 tons on board escaping . Booms have been put in place around the ship to stop the spread of oil and other pollutants such as detergents and sewage chemicals . With more than 4,000 people aboard , the ship was the size of a small town , Gabrielli said . Fuel will be replaced with water as it is removed from the ship 's tanks , keeping the ship balanced , said Dell'Anna , head of coastal authorities for the port city of Livorno . Gabrielli said Costa Cruises , the company that owns the cruise ship , is cooperative and was proving responsible , despite past errors . Both Costa Cruises and authorities have criticized Capt . Francesco Schettino , who is under house arrest and faces possible charges of manslaughter , shipwreck and abandoning ship . Prosecutors have accused the captain of piloting the ship too fast to allow him to react to dangers , causing the shipwreck , according to legal papers . Schettino maintains his innocence .
