An animation video shows the complex and delicate process of the salvage operation to raise the Sewol ferry in South Korea.
The ship has been lying on its side at a depth of 44 metres.
The operation to raise it began on Wednesday.
How far has it got?
Officials say the vessel was raised 13 metres above the surface of the sea by late morning local time on Friday.
It has been moved onto a semi-submersible vessel and then taken to a nearby port for an inspection, which could take up to two weeks.

When did the vessel sink?
Nearly three years ago. More than 300 people died.
It was structurally unsound, overloaded and travelling too fast on a turn when it capsized and sank during a routine trip off the southwest coast on April 16, 2014.
