An Iranian oil tanker that caught fire after colliding with a freighter off China’s east coast is at risk of exploding and sinking, Chinese state media have said.
The news came as three countries struggled to find its 32 missing crew members and contain oil spewing from the blazing wreck.
State broadcaster China Central Television, citing Chinese officials, said none of the 30 Iranians and two Bangladeshis who have been missing since the collision late on Saturday have been found as of 8am on Monday.
Meanwhile, search and cleanup efforts have been hampered by fierce fires and poisonous gases that have completely consumed the tanker and surrounding waters, CCTV reported.
The Panama-registered tanker Sanchi was sailing from Iran to South Korea when it collided late on Saturday with the Hong Kong-registered freighter CF Crystal in the East China Sea, 160 miles off the coast of Shanghai, China’s Ministry of Transport said.
China, South Korea and the US have sent ships and planes to search for Sanchi’s crew, all of whom remain missing. The US Navy, which sent a P-8A aircraft from Okinawa, Japan, to aid the search, said late on Sunday that none of the missing crew had been found.
All 21 crew members of the Crystal, which was carrying grain from the United States to China, were rescued, the Chinese ministry said. The Crystal’s crew members were all Chinese nationals.
It was not immediately clear what caused the collision.
State-run China Central Television reported the tanker was still floating and burning, and that oil was visible in the water. Photos distributed by the South Korean government showed the tanker on fire and shrouded in thick black smoke.
Chinese authorities dispatched three ships to clean the oil spill. It was not clear, however, whether the tanker was still spilling oil as of Monday and the size of the oil slick caused by the accident also was not known.
The Sanchi was carrying 136,000 metric tons of condensate, a type of ultra-light oil, according to Chinese authorities.
By comparison, the Exxon Valdez was carrying 1.26 million barrels of crude oil when it spilled 260,000 barrels into Prince William Sound off Alaska in 1989.
The Sanchi has operated under five different names since it was built in 2008, according the UN-run International Maritime Organisation.
The IMO listed its registered owner as Hong Kong-based Bright Shipping Ltd., on behalf of the National Iranian Tanker Co., a publicly traded company based in Tehran.
The National Iranian Tanker Co. describes itself as operating the largest tanker fleet in the Middle East.
An official in Iran’s Oil Ministry said 30 of the tanker’s 32 crew members were Iranians.
“We have no information on their fate,” he said on Sunday. “We cannot say all of them have died, because rescue teams are there and providing services.”
The official said the tanker was owned by the National Iranian Tanker Co. and had been rented by a South Korean company, Hanwha Total Co. He said the tanker was on its way to South Korea.
Hanwa Total is a 50-50 partnership between the Seoul-based Hanwha Group and the French oil giant Total. Total did not immediately respond to a request for comment.
It is the second collision for a ship from the National Iranian Tanker Co. in less than a year and a half. In August 2016, one of its tankers collided with a Swiss container ship in the Singapore Strait, damaging both ships but causing no injuries or oil spill.
