Ship rudder Cross Over

The new generation of efficient merchant vessel requires high standards of manoeuvring and propulsion efficiency. The new Cross Over Rudder design unites Becker Marine Systems’ expertise in rudder design and new propulsion efficiency technologies by introducing a new type of rudder featuring a rudder bulb and fairing cap. Main benefits of the new Cross Over Rudder: The new FEHC Flow Efficient Hub Cap An optimised rudder bulb with no loss of manoeuvrability Fuel savings of up to 7% due to efficient rudder design Improved course keeping No propeller hub cavitation Available for newbuildings and retrofits Designed for feeder vessels and ferries Optional trailing edge flap available Using the experience of aft ship optimisation with energy-saving devices and flow-optimised rudders, Becker is introducing the Cross Over Rudder as an improved propeller/rudder solution, including a new fairing hub cap (Flow Efficient Hub Cap or FEHC) and a new rudder bulb design with no loss of manoeuvrability. The FEHC and the rudder bulb reduce fuel consumption by up to 3% and prevent propeller hub cavitation. The design was optimised by our R&D department for swirled propeller flow using Computational Fluid Dynamics (CFD). Cap and bulb can be designed independently from the propeller manufacturer, which makes the Cross Over Rudder available for retrofits as well as newbuildings.
