Markey Machinery announced
recently that it is creating an
international network of factory-
trained sales and service centres.
Markey is currently evaluating
candidate companies around the world.
Its current focus is on qualified system
integration/service companies, located in
key markets distant from Markey's US
facility. The company expects to conclude
an agreement with an Australian firm
shortly, establishing a centre there.
In related news, a series of recent
extraordinary success stories has placed
Markey directly "centre stage" in the
international maritime spotlight.
Proof-of-concept of Markey's
"render/recover regeneration" was
displayed recently by Foss Maritime's fully
hybrid tug 'Carolynn Dorothy'. The "hard
data" from the world's first fully hybrid
tug is hard to ignore. Foss is a clear leader
in the development of green operations,
while Markey winches can return wasted
energy, thus reducing operating costs
while adding a higher level of winch
control when operating "on a short leash."
Last year's dramatic rescue of
the 'Carnival Splendor' off the coast
of Mexico provides further proof
of the strength of Markey electric winch
"We make no claim on the skill or
bravery of the crew," explained Markey
President Blaine Dempke, "but it's
rewarding to know that they had
enough confidence in our winch to do
what they did."
Dempke also clarified Markey's role
aboard the 'Carolynn Dorothy'. "In
developing the 'Carolynn Dorothy', Foss
sought to maximise its chances of success
by making low risk decisions where
possible. First, they chose a tug design
that had proved itself in nine previous
conventional builds; second, they utilised
their own Rainier Shipyard to tackle the
project; and finally, they chose Markey
Machinery to apply render/recover
technology in a regenerative application."
According to the company, that
customer confidence is well earned.
Markey support during and after the sale is
renowned, as are the strength and
durability of Markey winches. Maintaining
that level of support worldwide is the
primary purpose of this new program.

MAN Diesel & Turbo has confirmed that the MAN B&W
6S46MC-C8 engine with integrated SCR fulfils the IMO's
strictest emission standards.
The engine, a MAN B&W 6S46MC-C8 type capable of an
output of almost 7MW, was constructed in northern autumn
2010 by Hitachi Zosen Corporation at its Ariake works in
The engine is bound for a general cargo carrier, to be built at
the Nakai shipyard and scheduled to enter active service later this
year. The vessel was ordered by Japanese customer BOT Lease and
is to be operated by Nissho Shipping.
The first engine-start took place in January 2011. In
connection with this, MAN Diesel & Turbo dispatched a team to
Japan to commission the engine-control system -- the first in a
series of planned visits. The team also optimised the integration of
the SCR system that removes NOx from the engine's exhaust gas.
The SCR system features:
• More than 80 percent NOx reduction based on the load cycle
• More than 70 percent NOx reduction on each load point in the
• Easy switching between on/off modes for optimal emission
performance on high seas and coastal waters.
Ultimately, MAN Diesel & Turbo confirmed that, in a
world-first, the engine meets all emission requirements as
stipulated by the International Maritime Organisation's Tier-III
legislation, due to come into force in 2016.
When bringing the two-stroke engine performance up to
Tier-III standard, MAN Diesel & Turbo considered both SCR
(Selective Catalytic Reduction) and EGR (Exhaust Gas
Recirculation) techniques. Based on a general evaluation of
two-stroke engines, a high-pressure, urea-based SCR
configuration was chosen as the optimal SCR solution.
Søren Jensen, Vice President Research and Development,
Marine Low-Speed at MAN Diesel & Turbo said: "We haven't just
provided an engine and added an SCR system to it. On the
contrary, we have delivered a bespoke system. As engine
designer, builder and catalyst designer, MAN Diesel & Turbo and
Hitachi Zosen comprise a group of specialists that have delivered
an optimised propulsion/emissions package of engine,
engine-control system and SCR system."
Jensen concluded: "In the future, MAN Diesel & Turbo wants
not only to develop engines but also to design engines with
complete, emission-reduction systems. To that end, we envisage
collaborating with many other partners in times to come in the
same successful fashion as we have seen in Japan."
To achieve the desired, higher exhaust-gas temperature and
maximise NOx removal, the different elements of the emissions
package are laid out in series, with the SCR system placed before
MAN Diesel & Turbo's engine-control system has a number of
different ways to ensure the correct exhaust-gas temperature.
Uniquely, MAN Diesel & Turbo holds patents for a number of
