Striving for Lower Fuel Consumption

and a contra rotating propeller behind it mounted on a pulling mechanical thruster. The machinery has been confi gured to keep the initial cost low by avoiding expensive electric pods and drives, and by going to a simple mechanical drive of the forward propeller using a large bore main engine. A novel machinery and cargo ramp arrangement has been developed to facilitate also very large main engines, which are too high to fi t under the main deck. Both fuel consumption, and therefore also exhaust emissions, can be reduced by more than 10% with this new concept. Overall, the new concept offers a very attractive economic solution that represents state-of-the-art propulsion technology, while relying on well proven and reliable components.
