China has made a unique propeller for ships, inspired by dolphin skin to reduce fuel consumption and harmful emissions.
The propeller was tested on a 300,000 ton VLCC, which completed 3 oil delivery voyages, with 2% less fuel consumption, thanks to the new propeller.
China also stated that it can save 1.5% energy within a 2.5 year-maintenance cycle.
The VLCC, with bionic dolphin skin, sailed for more than 200 days and 35,000 nautical miles between Chinese coastal ports and Middle Eastern ports.
Since the VLCC consumes less fuel, if it operates with the dolphin skin propeller, it will save more than 300 tons of fuel every year, with economic benefits of more than $ 140,000 and a reduction of more than 900 tons of carbon dioxide emissions.
The research behind the new propeller design was done by a team from the Ningbo Institute of Materials Technology and Engineering, in collaboration with Cosco Shipping Energy Transportation.
Their focus was to develop a marine
