International experts say Safer vessel could dump four times as much oil as Exxon Valdez into Red Sea Winter currents would devastate marine life and livelihoods in six countries LONDON: A decaying tanker moored off Yemen’s Houthi-controlled coast is on the verge of creating one of the world’s biggest oil spills, scientists have warned. The Safer tanker holds one million barrels of oil — four times the amount that leaked from the Exxon Valdez in the catastrophic 1989 spill in Alaska. The Houthi militia has repeatedly blocked experts from accessing the ship, which was abandoned in 2015. The paper, published by “Frontiers in Marine Science,” called for the UN and its International Maritime Organization to take emergency action to remove the oil despite regional political tensions. “Officials should act immediately to secure the livelihood of the Red Sea’s peoples and the world’s largest marine refuge from climate change,” the paper said. According to the scientists, no one has yet accessed the vessel despite the UN saying last month that it had reached a deal with the Houthis for its experts to go onboard. In May, water breached the ship’s hull and entered the engine room and oil spots were seen near the tanker in September. “The Safer has been stranded and deteriorating off Yemen’s coast since 2015, giving the world the most advanced warning ever of a major oil spill,” the scientists said. “But this unique opportunity is being squandered.” Last week, a US official said that the Houthis refusal to allow access to the tanker was similar to the behavior of a terrorist goup. The militia, which sparked the Yemen war in 2014 when it seized the capital Sanaa, has been accused of a string of attacks against shipping in the Red Sea. The group was widely suspected in Tuesday’s attack on a ship as it unloaded fuel at Jeddah port. A small boat laden with explosives drove into the Singapore-flagged BW Rhine, sparking an explosion and fire but causing no casualties.
