BUFFALO, N.Y. — After nearly a month, the USS The Sullivans is floating again and is almost completely righted.

The Buffalo Naval Park shared a time-lapse video of the ship sinking and then being refloated.

The U.S. Coast Guard says the ship is still listing slightly in the range of .1 to .3 degrees.

This week, crews moved to the maintenance and decontamination phase of the project, with the Coast Guard saying pumping is around 95% complete. More than 585,000 gallons of water have been removed from the ship. A total of 53 holes were plugged.

One of the remaining concerns is the oil still inside the ship.

"I do want to let you know that there was an additional release on May 3 and an additional release on May 4," said Capt. Lexia Littlejohn of the U.S. Coast Guard. "A small amount that was discharged into containment around the vessel, and we want to make sure that that doesn't happen again."

The naval park is working to develop a re-opening plan and to recover the rest of the artifacts inside the ship.

The Coast Guard cautions that repairs so far are only temporary, and permanent repairs will have to be made at some point.
