@sgshipspotting: A brief tour of the @bergeolympus and its amazing WindWings which harness the wind's power to save fuel and carbon emissions On a normal day this can help save c. 2 tonnes of fuel or 6 tonnes of carbon (about 5%) but on the windiest of days in the South Atlantic it has helped save 20 tonnes of fuel or 60 tonnes of carbon - around 50%!! Thank you so much @bergebulk for inviting me on board to meet the crew and see the WindWings up close!
