Clean-up operations are continuing in Mauritius after the scuttling of the forward section of the broken capesize Wakashio.
The government said in a statement that the planned sinking of the bulker's bow had been completed on Monday, after it had been towed out to deeper water.
The National Crisis Committee posted to Facebook dramatic pictures of the vessel disappearing.
The 203,000-dwt ship (built 2007) grounded on a reef on 25 July, spilling 1,000 tonnes of fuel oil, and broke in two more than a fortnight later.
"There is no more diesel oil on the aft section of the casualty," the government said. This part remains stuck on the reef.
"A considerable amount of pollutants and other floating items have been further removed and this exercise is ongoing."
The island has brought in 10 boats to remove absorbent booms, with 40 fishermen involved in the operation.
Clean-up ongoing
Skimming operations and shoreline cleaning are continuously been carried out, the government said.
About 1,100 tonnes of liquid waste have been recovered, along with nearly 800 tonnes of contaminated solid waste.
Charterer Mitsui OSK Lines said owner Nagashiki Shipping had informed it that hydraulic oil had been removed from the bow before the deliberate sinking.
Another MOL worker arrived on site on 22 August to help manage the logistics and inventory of equipment, such as booms.
The Tokyo-headquartered charterer added: "The first clean-up equipment sent by MOL has arrived in Mauritius on 23 August. Thereafter, additional equipment such as masks, protective suits, oil absorbents, etc, will arrive in Mauritius on 26 August and 28 August."
