Seven of the 25 crewmembers were rescued in the South China Sea, and divers found three bodies. Fifteen have yet to be found.
Earlier attempts to pull the Naftogaz-67 tugboat to shallow waters failed, as the mast is embedded seven meters into the seabed, fixing the 2,723-ton vessel.
"Preparations for pulling up the Ukrainian vessel Naftogaz-67 are ongoing. The operation to lift the Naftogaz-67 has been postponed until Saturday, April 26," the ministry said in a statement.
The operation had been scheduled for April 24.
The families of the sailors that died in the accident are expected to receive around $20,000 each in compensation from the company that owns the tugboat, along with additional benefits and payments from the Ukrainian government.
