'Massive Floating Time Bomb': Warnings of Ecological, Humanitarian Disaster as Tanker Risks Dumping Four Times More Oil Than Exxon Valdez

A United Nations official raised alarm Wednesday about the potential threat of a major oil spill off the coast of Yemen, warning that an aging supertanker off the country's coast could dump four times more oil into the Red Sea than the Exxon Valdez oil disaster of 1989.

The remarks from U.N. Environment Programme (UNEP) executive director Inger Andersen to the U.N. Security Council paint a frightening picture of the environmental and humanitarian consequences posed by the oil in the FSO Safer.

Should a spill occur, it would "directly affect millions of people in a country that is already enduring the world's largest humanitarian emergency," said Andersen.

The 45-year-old vessel, under control of Houthi rebels since 2015, holds more than 1 million barrels of crude oil and has been described as a "massive floating time bomb" that "is corroding away rapidly as we speak."

The Associated Pressreported last month that "seawater has entered the engine compartment of the tanker, which hasn't been maintained for over five years," and the Houthis have so far blocked U.N. inspectors access to the ship.

"Rust has covered parts of the tanker and the inert gas that prevents the tanks from gathering inflammable gases, has leaked out," AP reported. "Experts say maintenance is no longer possible because the damage to the ship is irreversible."

Andersen, in her comments to the Security Council, pointed to "increasingly likely" scenarios of either a spill or explosion on the tanker, either of which would unleash "a serious, long-lasting environmental impact." Andersen further noted that the Red Sea is "one of the most important repositories of biodiversity on the planet" and said an oil disaster from the FSO Safer has the potential to impact 28 million people who rely on the sea and its coastal area for their livelihoods.

"If the SAFER leaks, potentially spilling four times more oil into the Red Sea than the Exxon Valdez oil spill," Andersen said, "ecosystems and fisheries would be damaged for an extended period into the future."

The UNEP chief pointed to a recent study analyzing potential threats of a spill. Among the worst case scenarios--which would happen if the spill took place between July and September--include that all of Yemen's fisheries would be affected, there would be a months-long closure of the crucial port causing a 200% spike in fuel prices in Yemen for several months and a doubling in food prices, and over 8,000 water wells would be at risk of contamination.

Even if a spill was immediately followed by actions to recover the oil and clean up the shoreline, "it would nonetheless take years for the ecosystems and the economies to recover," said Anderson. But immediate spill response could be marred by the fact that Yemen and its neighboring countries lack capacity for such action. The ongoing conflict in Yemen would be an additional obstacle to immediate remediation efforts, she said.

Efforts to prevent an oil spill or explosion are therefore paramount, said Andersen, pointing to the need to offload the oil and move the tanker. But, she stressed, plans to address a spill must still be in place.

"If the SAFER leaks, potentially spilling four times more oil into the Red Sea than the Exxon Valdez oil spill," Andersen said, "ecosystems and fisheries would be damaged for an extended period into the future."

Efforts to stave off the looming disaster can't wait any longer, she said.

"Time is running out for us to act in a coordinated manner to prevent a looming environmental, economic, and humanitarian catastrophe," Andersen said, calling for a U.N. team to have access to the vessel to assess the situation.

U.N. humanitarian affairs chief Mark Lowcock also addressed the impending diaster at the Security Council and urged Houthis to seize the "important opportunity here to take steps that will spare millions of their fellow citizens from yet another tragedy."
