Japanese shipowner Mitsui OSK Lines has trialled the use of bio-fuel supplied by ExxonMobil and bunkered onto an LNG carrier chartered to the US energy major.

MOL said 1,500-tonnes of biofuel was supplied by ExxonMobil Marine to the 171,800-cbm LNG carrier Papua (built 2015) in the Port of Singapore.

The marine biofuel used is a 0.50% sulphur residual-based fuel very low sulphur fuel oil processed with up to 25% waste-based fatty acid methyl esters — also referred to as FAME, which are primarily used as clean fuels added to conventional diesel fuels.
