About us Becker rudder profiles Established in 1946 and located in Hamburg, Germany Becker Marine Systems is a leading supplier of high performance rudders and manoeuvring systems for all types and sizes of vessels. Our extensive range of rudder profiles and configurations allows us to design any manoeuvring system tailored to your needs and requirements. The rudder profile determines the lift and drag of a rudder. Whether it is a high-lift rudder or a (more economical) standard profile, a special profile for cavitation avoidance, improving ships speed, fuel saving or navigation in ice Becker has the right solution for your ship s requirements. Our well-known products such as the Flap Rudder, the TLKSR Twisted Rudder and the Becker Mewis Duct are based on over 60 years of successful business in the world s shipping and shipbuilding industry. We would be pleased to offer you our services.

Becker rudder designs Rudder designs offer different solutions for rudder support. From full spade or heel-supported rudders for smaller and slower vessels to big vessels with KSR or HERUS support, Becker Marine Systems offers the full range. But when it comes to fast, big or both there is no alternative to Becker s proven KSR support, a solution which allows a rudder to be built at any size. KSR SUPPORT KSR King Support Rudder FULL SPADE Full spade rudder support HEEL SUPPORT Rudders with heel support
Becker rudder design KSR support KSR SUPPORT In order to avoid the typical disadvantages of conventional rudders, Becker Marine Systems has developed the KSR (King Support Rudder) bearing arrangement. With this arrangement the trunk is extended into the rudder blade so that the lower neck bearing is positioned as close as possible to the vertical centre of pressure of the rudder. This results in reduced stresses and bending moments in the rudder blade as well as in the rudder stock. FKSR Flap Rudder Schilling KSR FKSR Flap Rudder on the Nordby Mærsk KSR King Support Rudder Twisted, Flap, Schilling, NACA & other All types of larger size and/or higher speed
Becker rudder design Full spade FULL SPADE Full spade rudders are the solution of choice for smaller and low-speed vessels. The economic Becker Full Spade Flap Rudder (SC) is especially designed for typical applications such as river boats, supply and fishing vessels, tugs, coasters and small ferries. The Paivi, multi purpose vessel NACA Full Spade Rudder Full spade design Flap, Schilling, NACA & other Smaller and low-speed vessels e.g., river boats, tugs, coasters
Becker rudder design Heel support HEEL SUPPORT Heel-supported Becker rudders are economical systems for small and low-speed vessels. River boats, supply vessels, tugs, fishing boats and research vessels are all ideal candidates for this rudder solution. This design reduces loads on the neck bearing and the rudder carrier.

Fuel-saving, environmentally friendly Becker Mewis Duct BECKER MEWIS DUCT Becker Mewis Duct installation Becker Mewis Duct All single screw vessels All full-form vessels
Becker Mewis Duct BECKER MEWIS DUCT The Becker Mewis Duct was developed for full-form, slower ships and provides significant power savings. This results in reduced CO 2 and NO X emission as well as reduced operational costs. Fuel savings of 3 to 8 % can be achieved. Fuel savings in average 6 % Fuel savings up to 8 % in combination with a Becker Rudder Reduction of NO X and CO 2 emissions Suitable for newbuildings and retrofits Reduced vibrations and pressure pulses No moving parts, no service necessary Return on investment in about 1 year Installation time approximately 4 days The Samco Redwood, crude oil carrier Becker Mewis Duct and Becker Flap Rudder For more detailed information please ask us for the Becker Mewis Duct brochure.
Fuel-saving, environmentally friendly Becker Twisted Fin BECKER TWISTED FIN Based on three years operational experience with the Becker Mewis Duct Becker Marine Systems developed the Becker Twisted Fin as a new energy-saving innovation for container ships and other faster vessels with bulbous stern. The efficient device is placed in front of the propeller, reduces fuel consumption by 3% on average and even more in combination with a Becker rudder. And furthermore it reduces NO X and CO 2 significantly. Fuel savings of up to 3% Reduction of NO X and CO 2 emissions Return on investment in 6-15 months Structural guarantee of many years Guarantee of power reduction as verified by model test: Money saved or money back Suitable for newbuildings and retrofits No moving parts, no maintenance required Fast installation Installed Becker Twisted Fin Santa Clara, container ship Becker Twisted Fin All single screw vessels Container ships and other faster vessels
