UN completes removal of oil from decaying tanker off Yemen

The United Nations said on Friday it had completed the removal of more than 1 million barrels of oil from a decaying supertanker off Yemen's Red Sea coast, averting a potential environmental disaster.

UN officials and activists have been warning for years that the entire Red Sea coastline was at risk, as the rusting Safer tanker could have ruptured or exploded, spilling four times as much oil as the 1989 Exxon Valdez disaster off Alaska.

The war in Yemen caused the suspension of maintenance operations on the Safer in 2015. The ship is used for storage and has been moored off Yemen for more than 30 years.

"It is a major moment of having averted a potentially catastrophic disaster," said Achim Steiner, administrator of the UN Development Programme, which coordinated complex efforts to remove the oil from the ship.

Salvage crews operated for 18 days in a coastal conflict zone riddled with sea mines, amid high summer temperatures and strong currents, to offload the oil from the vessel.

Steiner said the UN raised more than $120 million for the operation, which required the purchase of a second tanker for the offloaded crude, aircraft waiting on standby to release chemicals to dissipate the oil in case of a spill and policies with more than dozen insurers to underwrite the operation.

"It was literally until the last minutes that we looked at this operation as one that had to ensure the highest degree of preparedness of risk mitigation," Steiner said.

"The best end to the story will be when that oil actually is sold and leaves the region altogether."

There is no agreement on how such a transaction will proceed and UN officials in Yemen will soon begin negotiations with the country's conflicting groups in an attempt to agree on how to share the proceeds of a sale of the oil, which is majority owned by Yemeni state firm SEPOC.
