Product launch: Becker Twisted Fin ®
new energy-saving device developed for container ships & other fast vessels
Becker Marine systems has reacted to the strong
demand of many shipping companies and after
two years of research based on experience with
the Becker Mewis duct® has developed a new
product called Becker twisted fin®, specially
designed for container ships and other types
of fast vessels with bulbous stern. the savings

familiar from the Becker Mewis duct® are reduced
becaused of increased drag of the design
at a speed greater than approx. 20 kn, which is
why the Becker Mewis duct® is for tankers, bulk
carriers and heavy load vessels. Becker Marine
systems is thus introducing the Becker twisted
fin® for faster ships with speeds above 18 kn.

BMs haMBurg – new head of procureMent departMent
Matthias frank joined the team at Becker
Marine systems in July 2012 as the head
of Materials Management, consisting
of procurement, order coordination and
order processing. Mr. frank’s exten sive
knowledge in procurement and
the new product evolved from the Becker Mewis
duct® and is also installed in front of the propeller
to generate a pre-swirl. the system thus
provides fast ships tangible energy savings. the
nozzle ring is significantly smaller and has a special,
flat profile to reduce drag. the fins famil iar
from the (continued on next page)
conducting large purchasing projects is based on twelve years of experience
at a german shipyard and a further nine years at shipyard subsuppliers
as well as in the offshore industry. Mr. frank decided to join
the team at Becker as he believes in the direction of the company and
its innovative products. Mr. frank’s goal is to support the direction of the
company and to enhance the good service level of the department.

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 emis-
sions – 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

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

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

and Ziegelwiesenkanal at the inland port of hamburg-harburg
Becker Marine systems has finally found the ideal location for
the construction of its new company headquarters. construction
of the new hamburg headquarters has already commenced and
relocation from the neuländer Kamp offices to Blohmstraße is
planned for mid-2013.
due to the continuous growth of the company additional space
is urgently needed for the steadily rising number of employees.
although the current head office was built in 2003, it no longer
meets space requirements. the new company building will have
room for over 150 employees and, with direct access to the water,
will provide the ideal setting for our team.
for the 25 th time the sMM is taking place in
hamburg this year and Becker Marine systems
is proud of having been an exhibitor for many
decades at what is now the world’s largest
shipbuilding fair. our historic picture shows
the 1976 Becker stand along with company
founder willi Becker.
as a company attached to its home it gives
Becker Marine system great pleasure to take
the opportunity that sMM provides to present
itself to indus try professionals from around
the world in its home town of hamburg. and
thus Becker Marine systems will also be represented
at the anniversary sMM this year.
visitors can experience presentations on the
company’s wide product range such as the
twisted rudder tlKsr® and twisted flap rudder
tlfKsr, the schilling® Ksr rudder, BiMs Becker
intelligent Monitoring system and the Becker
Mewis duct®. recently, Becker has received
an order for the largest full spade rudder ever
built measuring more than 90 m 2 . new products
developed by Becker’s r&d department will
also be introduced. one full-scale energy-saving
innova tion will be presented at the outside area
