The Omani Maritime Security Centre said on Tuesday that the Comoros-flagged oil tanker Prestige Falcon had capsized off the port of Duqm, adding that the search for the missing crew was ongoing.
Shipping data from the London Stock Exchange Group showed the tanker was headed to Aden in Yemen.
The shipping data showed the stricken vessel was a 117-metre-long oil products tanker built in 2007. Such small tankers are usually used only for short trips.
The official Oman News Agency reported on Tuesday afternoon that Omani authorities had conducted a search and rescue operation at the scene in coordination with maritime authorities.
The port of Duqm is located on Oman’s southwest coast near major oil and gas mining projects in the sultanate, including a major oil refinery that forms part of the vast Duqm Industrial Zone, Oman’s single largest economic project.
