The ship’s operator said the wreck of the Singapore-flagged X-Press Pearl “is now wholly sitting on the seabed at a depth of 21 meters (70 feet).”
A salvage crew was at the site to deal with any debris and report any spill, X-Press Feeders said.
The head of Sri Lanka’s Marine Environment Protection Authority, Darshini Lahandapura, also confirmed that the ship had sunk.
The Sri Lankan navy believes the blaze was caused by its chemical cargo, which included 25 tons of nitric acid and other chemicals, most of which were destroyed in the fire. But debris including burned fiberglass and tons of plastic pellets have already polluted nearby beaches. There are concerns that a spill of remaining chemicals and oil from the ship could devastate marine life.

Authorities extinguished the fire last week, but the ship then began sinking and attempts to tow it into deeper waters failed when its stern rested on the seabed. The ship had remained partly submerged until Thursday.
The government has asked the United Nations and some other countries for help in assessing the damage to the marine environment and coastal areas.
The country has submitted an interim claim of $40 million to X-Press Feeders to cover part of the cost of fighting the fire.
