A Cosco Shipping Lines container ship has been bunkered with “sustainable marine biofuel” by TotalEnergies Marine Fuels in Singapore in the first operation of its kind for the Chinese vessel-owning giant.

The French major’s marine fuelling arm said it supplied very low sulphur fuel oil blended with 20% second-generation waste-based and certified used cooking oil methyl ester to the 4,250-teu Cosco Houston (built 2012) in a ship-to-ship operation on 11 July.

TMF said that from a well-to-wake assessment, the biofuel will reduce approximately 17% of greenhouse gas emissions compared with conventional fuel oil.
