As shipowners warily eye 2050 and the recent mandate to re- duce greenhouse gas emissions by 50% by that date, it is commonly agreed that the technology to do so does not ex- ist today. According to the IWSA there has been a signi? cant trend developing around wind propulsion technologies over the last 12 months, driven by big numbers surrounding potential fuel sav- ings: 10 to 30% fuel savings for retro? t installations and up to 50% in fuel sav- ®
