DUBAI: An abandoned tanker carrying more than one million barrels of crude oil could contaminate vast areas of the Red Sea in a severe, long-term environmental disaster if it breaks up or explodes, experts warn. The Greek-flagged Sounion, struck on August 21 by Yemen’s Houthi rebels, was still on fire as recently as Saturday, maritime monitors said.

Threatening an oil spill four times the size of the 1989 Exxon Valdez disaster off Alaska, a leak or on-board blast could cause almost irreparable damage, said Julien Jreissati, Middle East and North Africa program director at Greenpeace. “Once released, an oil spill of this magnitude could be nearly impossible to contain, spreading contamination across vast areas of seawater and coastlines,” Jreissati told AFP. “The long-term impacts on marine biodiversity could be devastating, with oil residues potentially persisting in the environment for years or even decades.”

The Houthis have been firing drones and missiles at ships in the vital commercial route since November, saying they are targeting vessels linked

to the Zionist entity, the US and Britain in a show of solidarity with Palestinians over the Zionist war in Gaza. The Sounion, carrying 150,000 tons of crude oil, lost engine power and caught fire after the initial strike, forcing the evacuation of its 25 crew members by a French frigate serving with the European Union’s Aspides force, which is patrolling the area.

The Houthis then returned and detonated charges on the ship’s deck, setting off new fires. It is anchored west of the rebel-held port city of Hodeida, midway between Yemen and Eritrea. An attempt by private companies to tow away the burning ship was abandoned because it was “not safe” to proceed, Aspides, which was guarding the tug boats involved, said last week.

“Given that the vessel is a large, heavily laden oil tanker, now immobilized and on fire, the situation is extremely hazardous and unpredictable,” Jreissati said. “The potential for a major environmental disaster is significant as the vessel could break apart or explode at any time.” The 10-month Houthi campaign against shipping has killed at least four sailors and sunk two ships, including the Rubymar, which went down in March carrying thousands of tons of fertilizer.

The Sounion, however, poses the gravest danger yet. “This situation is an environmental catastrophe slowly unfolding in front of our eyes,” said Wim Zwijnenburg of Dutch peace-building group PAX. The Joint Maritime Information Center, run by an international naval coalition, on Saturday said daily surveillance flights had reported “several” fires on deck but no visible cargo oil slick.

A salvage and firefighting operation was expected to start this week. “Minor oil slicks were detected in some satellite images, likely linked with burned oil after the explosions or from the engine,” added Zwijnenburg. But “there has been no indication of a crude oil spill from the cargo that the ship is carrying”.

The Sounion recalls the danger posed by the FSO Safer supertanker, a 48-year-old ship with a corroding hull that lay abandoned for years off Yemen’s Red Sea coast. The ship had gone unserviced due to Yemen’s war between the Houthis and a Saudi-led coalition, which started in March 2015 and has caused a major humanitarian crisis in the impoverished country. In Aug 2023, the United Nations successfully completed the transfer of its cargo of more than a million barrels of oil in a costly operation that took years to organize.

Noam Raydan, an expert tracking maritime attacks for the Washington Institute for Near East Policy think tank, said the Sounion operation carried heavy risks. “Conducting salvage operations during the Houthis’ months-long attack campaign in the Red Sea has been challenging, and the Sounion incident will be no different,” Raydan said. “Finding suitable tugboats that are located near the region and willing to operate in such a risky environment can be difficult,” the expert added. Adding to the problems, naval forces “will need to remain near the tanker to prevent the Houthis from interrupting the (salvage) process”, Raydan said. – AFP
