Oldendorff Carriers is taking part in further trials of biofuel bunkers, this time with grain exporters in Australia.

The German owner’s 38,617-dwt Edwine Oldendorff (built 2016) sailed from Albany Grain Terminal in southern Australia on Sunday bound for Vietnam.

Australian grain industry ­cooperative CBH Group is shipping 30,000 tonnes of sustainably certified malting barley aboard the geared handysize.

The vessel has been bunkered with a BP-supplied biofuel blend for the trial, which is estimated to produce about 15% less greenhouse gas emissions for the journey than conventional fossil fuels.
