The Ministry of Oceans and Fisheries said in a statement that it would ask the government's safety agency to approve plans to hoist the ship from the seafloor off the country's southwest coast. The Ministry of Public Safety and Security said it would review the request on Wednesday.
The safety agency is widely expected to endorse the plan as President Park Geun-hye promised on Thursday the anniversary of the April 16, 2014, sinking to lift the ship.
Ministry officials said some of the work to lift the ship, such as deploying barges where workers can stay during the salvaging operation, could start in October.
Ministry officials have said the estimated cost of raising the ferry is about USD 91-137 million and that it's expected to take as long as 1 1/2 years.
