Three crew have died and another was reported as missing after a tug assisting in Wakashio clean-up efforts sank off Mauritius.
The tug 275-gt Sir Gaetan (built 1993), owned by the Mauritius Port Authority (MPA), went down off Poudre d'Or on 31 August, local media said.
Two deaths were quickly confirmed, while a third body was recovered of Grand-Gaube on Tuesday.
Sir Gaetan had been towing a barge carrying oil residues from the 203,000-dwt capesize, which grounded on a reef on 25 July, spilling 1,000 tonnes of fuel oil.
Wakashio later broke into two sections.
The tug reportedly took on water when it came into collision with the barge, shattering part of its hull.
Bad weather has been blamed.
Of the eight crew, four were rescued from a lifeboat.
