The Sewol was carrying 476 people when it took a sharp turn and capsized off the southwestern island of Jindo on April 16th, 2014, with the loss of 304 lives.
Of those who died, 250 were students from Dawon high school in Ansan, some 30 kilometers south of Seoul.
The government hopes to start salvaging the ferry from April 5th at the earliest and tow the vessel to a nearby port by the 3rd anniversary of the disaster on April 16th.
The work could be delayed, depending on the weather. Bad weather has hampered salvage efforts in the past./.
