An operation is under way to raise the Sewol ferry which capsized more than two years ago killing 304 people, mostly teenagers, in South Korea.
The raising of the Sewol, which sank on 16 April 2014, has been a central demand of the victims' families.
Many hope the bodies of the nine missing people will be recovered.
The disaster was one of the worst maritime disasters in South Korea in decades, and triggered widespread mourning.
The project, which will cost $73m (£47m), was announced last year by Seoul and is led by a Chinese consortium.
