The refloated Chinese tanker which ran aground on the Great Barrier Reef will have its hull and stability inspected by the Queensland State Government in Australia.
There is no sign of further oil leaking from the Shen Neng 1, which has already shed about four metric tons of fuel oil, Maritime Safety Queensland said.
The penalties for companies allowing oil spills may rise from A$1.7m ($1.5m) to $£10m ($9.2m), according to the Australian Government.
The ship, which left the Queensland port of Gladstone carrying about 68,000t of coal, hit a sandbank after deviating from its planned course on 3 April.
Salvage teams managed to pump out about 1,000t of heavy fuel oil from the vessel before it was refloated.
