After nearly a week of burning at open sea, a Greek-owned VLCC released a quantity of fuel into the Indian Ocean, Sri Lankan authorities said on Tuesday.

“A narrow diesel oil patch extending to one kilometer away from the ship has been observed,” the Sri Lanka Navy said in its most recent update.

The fire on the 300,000-dwt New Diamond (built 2000) has been raging since 3 September after a boiler exploded in the ship's main engine room leaving one Filipino seaman dead.
