The USS Guardian ran aground on a reef off the Philippines on January 17
The U.S. Navy plans to cut the ship into pieces, then haul them away
The Navy is awaiting the arrival of a crane ship
The U.S. has assured the Philippines of "appropriate compensation" for reef damage
Removing a stranded U.S. minesweeper from an environmentally delicate reef off the Philippines may take until April, the state-run Philippines News Agency reported Wednesday, citing the Philippines Coast Guard.
The U.S. Navy is preparing to extract the USS Guardian from the Tubbataha Reef, a Philippine national park and UNESCO World Heritage site where the 224-foot-long ship ran aground on January 17.
The Navy plans to cut the 1,312-ton minesweeper into pieces and then, with the help of two contracted crane ships, lift the pieces and carry them away.
Philippines Coast Guard Rear Adm. Rodolfo Isorena said Wednesday that he hopes the salvaging will begin soon so that further damage to the reef will be limited, the Philippines News Agency said.
One of the crane ships has arrived in the area, about 80 miles east-southeast of Palawan Island in the Sulu Sea, and the other is on its way, the news agency reported.
Navy spokesman: Reef’s location misplaced on chart
The ship is estimated to have damaged about 4,000 square meters (about 43,000 square feet) of the reef, the news agency said. Various U.S. officials, including Navy Vice Adm. Scott Swift last month, have apologized to the Philippines for the incident, which the U.S. Navy and the Philippines Coast Guard are investigating.
Philippine officials said last month that the country would seek compensation for reef damage. The U.S. ambassador to the Philippines, Harry Thomas Jr., assured the Philippines on Monday that the United States “will provide appropriate compensation for damage to the reef caused by the ship.”
The reef is home to a vast array of sea, air and land creatures, as well as sizable lagoons and two coral islands. About 500 species of fish and 350 species of coral can be found there, as can whales, dolphins, sharks, turtles and breeding seabirds, according to UNESCO.
Originally, only the ship’s bow was on the reef, but waves pushed the entire ship onto it. The ship’s wood-and-fiberglass hull was penetrated, allowing a significant amount of water into the ship, the Navy said.
Crews have been working to remove hazardous materials from the vessel and anything that could still be useful to the Navy. The Navy has reported no oil slicks; the ship’s 15,000 gallons of diesel fuel have been removed.
One of the environmental concerns is that algae will grow on dead or scarred corals, park Superintendent Angelique Songco said.
“Their presence makes it hard for other corals to regenerate as they cover the substrate,” Songco wrote in an e-mail to CNN on Wednesday. “We expect an increase in the incidence of grazer fish species in the area that feed on the algae. Hopefully they are hungry enough to control algae populations to enable hard corals (to) take root in the substrate.
“So you see, the balance we have been trying to maintain has been upset. For that particular area at least, coral evolution starts all over again – but not until salvage operations are over.”
The salvage operation also may hurt tourism, because it will happen at the start of the park’s main tourism window of March to early June, Songco said.
Songco said she hasn’t heard of any pre-booked tourists canceling. But the park, which is celebrating its 25th year, will have to close two of its 15 major diving sites during the operation, she said.
“We will not (be) able to offer divers the full measure of the Tubbataha experience,” she said.
