Vroon acquired MT ST Charlotte on Jan. 20. 2015. This 2006-built bitumen/molten sulphur tanker will be renamed Iver Ability and brings the total number of Vroon's bitumen tankers to twelve, according to the company.

The vessel is currently on charter to Total for the carriage of molten sulphur and bitumen cargoes. She is operating in the Atlantic basin and, following her delivery to the company in Antwerp, will proceed to Immingham to load a cargo of molten sulphur.
