Rear Admiral Thomas Carney, who is in charge of the salvage operation, said the fuel was taken out first to remove any risk of a spill, ABS-CBN News reported. Tubbataha Reef in the Sulu Sea, where the Guardian went aground, is a national marine park and a UNESCO World Heritage Site.
The fuel was transferred to a Malaysian tugboat, the Vos Apollo.
The Navy hopes to lift the minesweeper off the reef. Two crane ships are scheduled to arrive Friday.
