Caterpillar to provide combined marine propulsion systems for Scandlines Ferries
Caterpillar Marine Power Systems was
recently selected to provide combined
propulsion systems for two Scandlines
The two ferries will each be equipped
with five MaK 9 M 32 C engines with Cat
Common Rail. Each M 32 C engine
produces 4,500kW at 600rpm for
22,500kW of total power per vessel. The
engines are optimised for smokeless
operation and reduced nitrogen emission
levels, fulfilling IMO II requirements.
"Based on the success of the retrofitted
M 32 C engines on container vessels,
Scandlines asked Caterpillar to deliver the
engines for a unique combined propulsion
system for two new single-end car ferries,"
said Andreas Banck, Caterpillar Motoren
Senior Test Engineer. "The MaK engines
will power both the main propulsion
engines and the alternators enabling
Scandlines to reduce maintenance costs
and operate the ferries in a safe,
Caterpillar initially developed the Cat
Common Rail system for the M 32 C
engine series in 2006. The 'Edith Maersk',
owned by A.P. Moeller -- Maersk, utilised
the first M 32 C auxiliary engine
retrofitted with Cat Common Rail. Cat
Common Rail features electronically
controlled, fully flexible injectors capable
of injecting all fuels standardized
according to ISO 8217 requirements,
enabling optimal combustion and low
emissions at all levels. Cat Common Rail
can be retrofitted on the M 32 C.
"Another remarkable aspect of the M
32 C engine is the option to retrofit the
engines to Dual Fuel operation at a later
stage if necessary," said Frank Kircher,
Division Manager, Caterpillar Marine
Systems Integration. "This gives
Scandlines the freedom to decide how
they would like to operate the vessels in
2015 when more stringent rules for the
Sulfur Emission Controlled Area (SECA)
Keel laying began in June 2010 at the P
& S Werften (formerly known as
Volkswerft) Stralsund yard in Germany.
Both vessels will be delivered to
Scandlines in 2012. The two ferries will
operate between Rostock, Germany and
While the engines will be
manufactured at the Caterpillar factory in
Kiel, Germany, a collaboration between
European Cat Dealers Zeppelin Power
Systems and Pon Power Scandinavia will
provide Scandlines with sales and
installation support, as well as product
support and service.
"We're pleased to be able to provide
Scandlines with a tailor-made solution
that covers the power requirement
throughout all operating conditions,"
noted Territory Sales Manager Ulf
Hannemann. "Our customers have been
pleased with the reliability of our engines,
the reduced soot emission levels provided
by Flexible Camshaft Technology (FCT)
and the operational flexibility Cat
Common Rail offers."

A Caterpillar MaK 9 M 32 C engine
Alfa Laval recently announced the
arrival of a new version of the
In addition to a range of key features
that make it more robust, the new
S-separator offers greater efficiency that
allows the same amount of oil to be
handled with a smaller separator.
Alfa Laval's new S-separator is a highly
anticipated update of one of the
company's flagship marine products. In
the years since its introduction, the
S-separator has set the standard for engine
protection and separation efficiency,
particularly in working with demanding
residual fuel oils.
The new and improved S-separator
provides even greater separation
efficiency, not least due to a major
increase in separation area. In addition, it
features stronger discs and a more robust
drive system, which combine with
existing advantages to create the lowest
possible lifecycle cost.
The increased efficiency of the new
S-separator is the result of smart
enhancements in the separator disc stack.
Increased separation area, disc modifications
and other improvements allow up to 20
percent more flow with retained separation
performance. Since these changes do not
affect the separator's small footprint, ship
operators can now handle the same amount
of oil with a smaller separator.
Additional changes can be found
in the S-separator drive, including
sturdier friction blocks, a more resilient
bearing system and a more powerful
lubrication system. Together, these
modifications further boost the
S-separator's high reliability.
Despite the many changes in the new
S-separator, there is also much that
remains the same. This includes the
wear-reducing CentriLock snap ring and
CentriShoot discharge system, as well as
the S-separator's unique Alcap function,
which automatically detects and adjusts
to the nature of the oil.
"Naturally we've kept the
groundbreaking features that have given
the S-separator its leading position on
the market," said Joakim Thölin, General
Manager of Alfa Laval Marine & Diesel.
"Combined with the new features, they
give the updated S-separator the highest
possible reliability and the industry's
lowest lifecycle cost."
Like its predecessor, the new
S-separator also features the modular
EPC 60 controller and is part of Alfa
Laval's S and P Flex delivery concept,
now available worldwide.
