AKIPRESS.COM - A tanker carrying Iranian oil and run by the country’s top oil shipping firm was ablaze and spewing cargo into the East China Sea on Sunday after colliding with a Chinese freight ship, leaving the tanker’s 32 crew members missing, the Chinese government said.

Thick clouds of dark smoke could be seen billowing out of the Sanchi tanker, engulfing the vessel as rescue efforts were hampered by bad weather and fire on and around the ship, Mohammad Rastad, head of Iran’s Ports and Maritime Organisation, told Iranian television. 

The Sanchi, run by the country’s top oil shipping operator, collided with the CF Crystal about 160 nautical miles off the coast near Shanghai and the mouth of the Yangtze River Delta on Saturday evening, the Chinese Ministry of Transportation said in a statement, Reuters reported.

The Panama-registered tanker was sailing from Iran to South Korea, carrying 136,000 tonnes of condensate, an ultra light crude. That is equivalent to just under 1 million barrels, worth about $60 million, based on global crude oil prices.

The last major oil tanker disaster was the sinking of the Prestige off Spain in November 2002, which was carrying 77,000 tonnes of heavy fuel oil and caused one of Europe’s worst environmental catastrophes.

About 63,000 tonnes of its cargo leaked into the Atlantic, damaging beaches in France, Spain and Portugal and forcing the closure of Spain’s richest fishing grounds.

That was almost twice the size of the Exxon Valdez spill, which ravaged Alaska’s coast in 1989.
