Becker Twisted Fin® Advancement of Becker Mewis Duct® for fast vessels with bulbous stern Becker Marine Systems has reacted to the heavy demand of shipping companies for an energy-saving device for faster vessels. After two years of research and based on three years operational experience with the Becker Mewis Duct® a new energy-saving device for container ships and other types of fast vessels with bulbous stern is entering the market – the Becker Twisted Fin®. • Fuel savings of up to 3% • Reduction of NOx and CO2 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 The Becker Twisted Fin® installed on Hamburg Süd’s Santa Clara

Becker Twisted Fin® Illustration of water flow influences on the Becker Twisted Fin® The development from duct to fin Becker Marine Systems has focused on energy savings and pro­ vides one of the most efficient energy-saving devices for the mar­ itime market with the Becker Mewis Duct®. On average, power savings of over 6% could be achieved for large and slow vessels such as tankers and bulkers. The savings from the Becker Mewis Duct® are reduced at speeds above approx. 20 knots. Becker Marine Systems is now introduc­ ing the Becker Twisted Fin® for faster ships with speeds above 18 knots....

Becker Twisted Fin® First order – ten installations After the successful model tests of the Becker Twisted Fin® prototype at the beginning of 2012, Becker Marine Systems signed a contract with Hamburg Süd in June 2012.
