We worked closely with HYUNDAI and MARIC to develop the most economical Newcastlemax hull forms. Both designs feature a Becker Mewis duct, a rudder bulb and other fuel saving devices, to make them the most environmentally friendly Newcastlemaxes afloat.
Becker Mewis Duct
The Becker Mewis Duct and the rudder bulb are power-saving devices providing fuel savings and reduced greenhouse gasses. The Mewis Duct enhances the flow of water to the propeller to increase thrust. The rudder bulb is an additional power saving device which changes the hub vortex to streamline the water flow behind the propeller. These two “eco features” produce a fuel savings of 5-8%.
The spoon bow of our new Newcastlemax bulk carriers is designed to optimize the flow of water around the bow and provide optimal cargo on draft characteristics.
Auxiliary Engine Economizer
Fitted with an auxiliary engine economizer, our Newcastlemax vessels are designed to re-capture waste heat from the auxiliary engines.
Maximum power efficiency
Maximum power efficiency is obtained using a Mark 9 MAN Diesel & Turbo G-type main engine with an ultra-long stroke. The ultra-long stroke results in lower engine speed and a lower rpm which allows the use of a larger propeller. The larger propeller is significantly more efficient in terms of propulsion which reduces fuel consumption and CO2 emissions.
