The 57,000 dwt Aquila, delivered to its owner Delphin, is incorporated with the Mewis Duct, a propulsion improvement device for ships. The duct is able to reduce power requirement by improving water inflow toward the propeller to achieve higher overall propulsion efficiency.
A bulk carrier running at 14 knots per hour would have exhausted 29.4 metric tonnes of bunker fuel without the Mewis Duct. Installation of the device would allow the bulker to burn 26 metric tonnes of fuel at the same speed.
