The South Korean Sewol ferry has completed its final journey.

The ferry has arrived at the port of Mokpo, according to China's Shanghai Salvage Company, which undertook the operation to raise the vessel.

The stricken 140-meter vessel resurfaced from bottom of the sea on Feb 25, had sludge pumped out, and was then stabilized with the help of two barges. It's estimated that the 14,000-ton wreck contained nearly 4,000 tons of sludge and sea water.

The most difficult part of the salvaging work, involving 590 days of preparation, is to keep the vessel at the original angle it sank, to ensure the ferry won't break apart during transportation, and to allow an investigation to be carried out into why it sank.

The Sewol ferry sank on its regular overnight journey from Incheon to the volcanic island of Jeju on April 16, 2014. A total of 304 people, most of whom were high school students on a school trip died, with investigators concluding that the sinking was a man-made disaster.
