Singapore shipowner Berge Bulk has finally got its hands on the world’s biggest wind-assisted cargo vessel.

The 210,000-dwt Berge Olympus (built 2018) has been retrofitted in China with four huge WindWings designed by UK company BAR Technologies.

The companies claim that these rigid structures, made by Yara Marine Technologies and taller than a 10-storey building, can save six tonnes of fuel per day and cut CO2 emissions by 19.5
