A Philippine oil tanker sank in Manila Bay early on Thursday after encountering huge waves, and the coast guard was working to determine whether the vessel was leaking oil — in what could be a major spill — after it rescued 16 of 17 crew members in a nighttime operation, officials said.
The tanker Terra Nova left Bataan province en route to the central province of Iloilo with about 1.4 million liters (370,000 gallons) of industrial fuel oil stored in watertight tanks when it got buffeted by huge waves and took on water. The crew struggled to steer the tanker back to port but it eventually sank shortly after midnight, coast guard spokesperson Rear Admiral Armando Balilo said, citing statements from surviving crew members.
The sinking followed days of monsoon rains, exacerbated by a passing offshore typhoon, that caused landslides and floodings across the archipelago, leaving at least 22 people dead and displacing more than half a million people.
An aerial survey spotted an oil spill about 3.7 kilometers (2.3 miles) long near the rough seawaters where the tanker sank but that may have come from the fuel intended to power the tanker’s engine, not the much greater amount of fuel the Terra Nova was carrying as cargo, Balilo said.
A coast guard ship, the BRP Melchora Aquino, was in the waters where the tanker sank, more than 6 kilometers (about 4 miles) from Bataan province’s coast, to search for the last missing crewman and to carry out an initial assessment of the tanker’s fuel oil cargo, Balilo told an online news conference. He added that the coast guard was bracing to contain a possible major oil spill.
“There’s a big danger that Manila would be affected, its shorelines, if the fuel leaks because this happened within Manila Bay. It’s part of the contingency we’re preparing for,” Balilo said. “The effect on the marine environment would not be good.”
Balilo later said the oil tanker sank at a relatively shallow depth of 34 meters (111 feet), based on an initial assessment, and raised the possibility that its fuel oil cargo could be siphoned off by special ships in a delicate operation that could take about a week.
