The amount includes $80 million to transfer the more than 1 million barrels of crude oil the FSO Safer is carrying to storage, said David Gressly, the U.N. resident and humanitarian coordinator for Yemen.
The pledging conference, co-hosed by the U.N. and The Netherlands, comes more than two months after the U.N. and Yemen's Houthi rebels reached an agreement to transfer the tanker's contents to another vessel.
The Iranian-backed Houthis control Yemen's western Red Sea ports _ including Ras Issa, just 6 kilometers (about 4 miles) from where the FSO Safer has been moored since the 1980s.
Gressly said the vessel ``is slowly rusting and going into significant decay,'' and could explode, causing massive environmental damage to Red Sea marine life, desalination factories and international shipping routes.
``Every day that passes, every month that passes, every year that passes, increases the chance that the vessel will break up and spill its contents,'' he warned in a news briefing earlier this week.
He said the U.N. estimates that about $20 billion would be needed to just clean up an oil spill.
Gressly said the first phase of salvage should be completed by the end of September, otherwise it could face turbulent winds that start in October.
The Japanese-built tanker was sold to the Yemeni government in the 1980s to store up to 3 million barrels of export oil pumped from fields of Marib province, currently a battlefield. The ship is 360 meters (1,181 feet) long with 34 storage tanks.
Since 2015, annual maintenance on the ship has come to a complete halt. Most crew members, except for 10 people, were pulled off the vessel after the Saudi-led coalition entered Yemen's civil war in 2015 on the side of the internationally recognized government.
Yemen's conflict started in 2014 when the Houthis took control of the capital and much of the country's north, forcing the government to flee to the south, then to Saudi Arabia.
The U.N. has repeatedly warned that the tanker could release four times more oil than the notorious Exxon Valdez disaster off Alaska in 1989.
