Safe Bulkers tests biofuels

The Troodos Oak received 346 metric tonnes of biofuel blend B20, consisting of 20% spent bleaching earth oil mixed with conventional very low sulphur fuel oil (VLSFO).

For the purpose of CO₂ emissions reporting schemes European Union – MRV scheme and IMO DCS scheme, the reported CO₂ emissions as verified by Lloyd’s Register and accepted by Cyprus Flag are by 20% lower compared to the VLSFO.

No modification to existing ship equipment was required. No operational abnormalities or wear have been observed in main engine and diesel generators.

The project was performed in cooperation with vessel’s charterer Cargill, Cargill Marine Fuels and Oilchart as suppliers of the blended bio bunkers, the vessel’s classification society Lloyds Register and Cyprus Flag. The trial followed the guidelines of EU’s Renewable Energy Directive “RED II” on calculating CO₂ emissions.

The company will continue to explore potential use of biofuel blends by further expanding the project with Cargill to include additional vessels and higher biofuel blends, measuring in addition the nitrogen oxide emissions.
