A biofuel test on an Eastern Pacific Shipping MR tanker has revealed a substantial drop in carbon emissions, but higher consumption.

Speaking at an International Maritime Organization symposium on biofuel, chief executive Cyril Ducau described the cross-Atlantic trial on the 47,400-dwt Pacific Beryl (built 2010) as a success.

No operational issues were encountered and the whole 254-tonne stem of 100% biofuel from Dutch producer GoodFuels was consumed without interruption over 11 days.
