Gunmen have released a bunker tanker hijacked off Congo on 29 October.
Maritime Bulletin reported that the 9,600-dwt Anuket Amber (built 2008) was freed on Friday and was heading northwest, south of Lome in Togo.
Armed guards were on board and the 12 crew were said to be safe and well.
The vessel, managed by Norbulk, was seized while it was bunkering the 84,000-cbm BW LPG vessel BW Frigg (built 2016).
On the same day, gunmen attacked the 2,300-dwt AHTS Ark Tze (built 2009) and kidnapped four crew.
They were said to have been transferred to Anuket Amber.
The offshore vessel is operated by RK8 Shipmanagement of Singapore.
A spokesman for RK8 had no further information on the situation.
