Ship rudder Becker Bulb

TIMO Tier 2, VGP, EEDI and SEEMP are some examples of the increasing number of environmental regulations and guidelines coming out recently. All of these target the overall reduction of emissions. Becker Marine Systems is a strong partner in the market for environmentally friendly and money-saving technologies. Due to its longtime experience, Becker is able to provide customised rudder solutions for every type of ship and operational profile. Replacing a vessel’s conventional half spade or full spade rudder with a Becker bulb rudder will increase its propulsion efficiency by approx. 3-4%. It also turns the rudder arrangement into a high-performance propulsion/manoeuvring package. The main benefits of a Becker Bulb Rudder are: No rudder-induced hub cavitation Reduced rotational losses in the slipstream Reduced hub vortex losses Reduced vibration and noise Better performance with bulb rudders Ship rudders are generally situated in complex, highly turbulent flow fields. This offers opportunities for significant power savings by recovering some of the associated flow energy losses through careful design of the propulsion and steering system. The Becker rudder bulb provides such an optimised solution.
