Product launch: Becker Twisted Fin ® new energy-saving device developed for container ships & other fast vessels Becker Mewis duct® on the inside of the nozzle ring extend outwards beyond the nozzle. to prevent the formation of a swirl with cavitation at the ends of the fins Becker has developed special end caps for the fins similar to the winglets familiar from modern aircraft wings and helicopter blades. the small nozzle ring generates thrust, provides stability to the fins and reduces vibrations. computational fluid dynamics (cfd) tests show an average of 3% energy savings for container ships. Model tests being carried out in March this year confirmed these cfd results. LNG Hybrid: Becker initiates emission-free ferry at Becker Marine systems the environment means more than just manoeuvring and propulsion. the company is meeting its responsibilities towards reducing shipping emissions worldwide. the idea to develop an emission-free ferry with very low draught for shallow european coastal waters came about after taking a closer look at the precious and fragile wadden sea national park near hamburg. the working title of this draft was “wadden sea ferry“ and is now being finalised by the name project “fering”. the newly developed project “fering“ ferry was designed by ingenieurbüro für schiffstechnik ingo schlüter gmbh & co. Kg and is exclusively powered by environmentally-friendly liquefied natural gas (lng) with no particle emissions. the additional purchase of emission certificates makes it possible to offer a completely carbon neutral, “green” ferry service. pollution of the sensitive coastal waters with sulfur oxides and exhaust gas particles will be reduced to zero. co 2 emissions are reduced by 40% and the out- put of nitrogen oxides even by as much as 90%. each passenger will not only benefit from a flexible booking system with guaranteed transport for regular customers, but will also be making a contribution to environmental protection by purchasing a ticket. project “fering” is far beyond the first planning phase. in cooperation with shipping company schramm group, energy partners eon hanse wärme and gasnor, classification society Bureau veritas and the ship designers at ingo schlüter Marine consultants and sdc ship & design consult a new ferry design is being created that will already be going into service on the dagebüllföhr-amrum route in summer 2014. the new ferry meets the latest environmental protection standards and at a length of 70 m, a width of14 m and very low draught will provide space for 250 passengers and 50 cars. a model of the new “fering” ferry will be on display at this year’s sMM. the operation of the best energy-saving results are obtained with the combination of a Becker twisted fin® and the Becker tlKsr® twisted rudder. Benefits of the new Becker twisted Fin®: • Fuel savings of up to 3% • reduction of no x and co 2 emissions • Suitable for newbuildings and retrofits • no moving parts, no maintenance required • Fast installation • Structural guarantee of many years two ferries of this design is being planned for the line to föhr and amrum. Both ships will be built at european shipyards and equipped with the latest lng hyBrid technology to ensure that opera tion in the fragile environment of the wadden sea will be as low as possible in emissions – without passengers having to accept ticket prices higher than those of the competition. in addition to project “fering”, Becker’s lng hyBrid department (www.lng-hybrid.com) is working on other applications of this environmentally-friendly propulsion technology. thus, in cooperation with aida the idea recently arose of employing an lng hyBrid-powered barge for supplying electricity to cruise ships during port sojourns. electricity supplied via the lng hyBrid Barge from the water will avoid pollution of the port arising from shipboard, diesel-powered power units. local residents of the port can also look forward to air free from soot particles, which has been a big problem in the hamburg’s new hafencity.
Order highlights: Becker Marine Systems products stX offshore & shipBuilding Becker Marine systems has been selected by stX offshore & shipbuilding to design and supply the largest full spade rudders ever built for Zodiac’s container vessels. each of the rudders will have an area of 93m 2 . the rudder type will be Becker Marine systems’ well proven tlKsr® (twisted leading edge King support rudder) for the 400.0 m long and 54.0 m wide 16,000 teu container vessels. this very remarkable order for six of the largest container ships continues the long, very professional and reliable business relationship between stX offshore & shipbuilding and Becker Marine systems. stX and Becker have already cooperated successfully in previous large container ship projects. the rudders will be produced in europe and asia at Becker Marine systems’ subcontracting fabricators. together with the above order for the tlKsr® rudders, stX placed another order with Becker Marine systems for the delivery of six Becker Mewis duct® with an option of three more for stX Mr product tankers for various ship owners. in total, Becker Marine systems has received orders for 16 Becker Mewis duct® for the same type and ship size from stX. the Becker Mewis duct® are designed to gain up to 6% propulsion efficiency in loaded condition for stX Mr product tankers. china navigation gerMan governMent Becker Marine systems has been awarded the order from china navigation in singapore for the delivery of eight Becker Mewis duct®. china navigation has signed Zhejiang ouhua shipyard to build a series of 31,000 dwt Multi purpose vessels, with the design originating from neptun ship design. the vessels will carry 2,082 teu, but are also designed to carry general cargo and various other cargoes. despite the already optimised hull lines the tailor-made Becker Mews duct® added another 4% of energy saving during the model tank test at hsva. the first Becker Mewis duct® of this order will be delivered at the end of 2012. Becker Marine systems signed a contract for the delivery of eight twisted full spade rudders (tlKsr®) with dalian shipbuilding group and hudong Zhonghua shipbuilding. the high-efficiency rudders of 75 m 2 will equip 10,000 teu container vessels for china shipping container lines (cscl). Broad experience with high-efficiency full spade rudders and the convincing results of tank and cavitation testing were the main reasons for cscl choosing the rudders from Becker Marine systems for their container vessels of 335.0 m length and a service speed of around 24 kn. all vessels will be delivered in 2013. the german government has ordered a new deep-sea research vessel as a replacement for the existing Sonne vessel. the order was given to Meyer neptun group. Becker Marine systems has offered the shipyard the delivery of a special heracles flap rudder. the Becker spade highlift performance flap rudder gives the vessel the necessary manoeuvrability for its working profile in high speed and low speed conditions. the two Becker rudders have a rudder area of 7.26 m 2 per rudder with a max. rudder angle of 2 x 45°. according to the shipyard the german government will take delivery of the research vessel in 2014. dalian & hudong Zhonghua coBelfret cobelfret ordered two Becker Mewis duct® for their bulker newbuildings at yangfang ship yard in china. the energy-saving Becker Mewis duct® is an essential part of the environmentally-friendly 35,000/37,000 dwt “seahorse 35/37” handysize bulk carrier concept. the design fulfills the 2025 energy efficiency index, eedi. the vessel type has an overall length of 180.0 m, a breadth of 30.0 m and a service speed of approx. 14 kn. of the existing orders of the “sea horse 35/37” design, 16 vessels will be equipped with the Becker Mewis duct®.
