The Japanese owner of the Kokuka Courageous told CNN the 27,000-ton tanker had been attacked “by some sort of shell” off Fujairah, a port in the United Arab Emirates. The ship suffered damage to its starboard hull.
The ship’s operator, Singapore-based BSM Ship Management, said in a statement that the Kokuka Courageous was about 14 nautical miles from the coast of Iran.
A second tanker, the Front Altair, was also attacked while sailing between the UAE and Iran, the Norwegian Maritime Agency said in a statement.
“There were reportedly three detonations on board the ship,” the agency said.
The Strait of Hormuz links the Gulf of Oman and the Persian Gulf, separating Oman from its eastern neighbor, Iran. Deep enough to handle the biggest tankers, the strait is only 21 miles wide at its narrowest point.
The US Energy Information Administration describes it as the “world’s most important choke point,” with roughly 80% of the crude it handles destined for markets in Asia.
Second incident in two months
The attacks come amid rising tensions in the region, where the United States and its Arab allies including Saudi Arabia are increasingly at loggerheads with Iran.
The initial findings of an international investigation into the attacks concluded that a “state actor” was the most likely culprit. Iran has denounced the attack and denied involvement.
The price for Brent crude, the global benchmark, surged 4.4% to $62.59 a barrel.
Crude oil prices have drifted lower in recent months as a huge surge in American production more than offset the effect of US sanctions on oil producers Venezuela and Iran, and OPEC supply curbs. Slowing global economic growth in the face of trade disputes has also weighed on prices.
In a report published Thursday, the cartel downgraded its forecast for crude oil demand in 2019 because of sluggish demand. It also said that production by member nations fell to 29.9 million barrels per day in May.
Khalid al-Falih, Saudi Arabia’s energy minister, said last week that OPEC and Russia are close to a deal to extend production cuts they implemented at the start of the year. Those cuts are due to expire at the end of June.
