Converters
In the last few
years, many of
our ports have
come under great
pressure to
improve their
emissions from
diesel gas and
other
contaminates that
pollute our air.
The volume of
global trade has
been rising
steadily in the
past few years,
and nearly 80
per cent
of global trade
is by sea.
While ports are
seeing increased
economical
activity,
countries around
the world are
grappling with the
health effects
of
shipping-related
pollution. Until
recently,
ocean-going
vessels have
been under few
regulations, and
most of them use
the least
expensive and
dirtiest fuel
available.
Health issues
and global
warming have
proven that we need
stronger
regulations aimed
at cutting
shipping related
emissions. Most
will agree that
these new
regulations are
not strong
enough, and most
of the
regulations are
still not
legally passed,
enforced or monitored.
The CARB Plan
targets a 20 per
cent
reduction in
diesel PM by
2010 from 2001
levels, which it
claims will
reduce health
risks by 60 per
cent or
more by 2020. It
is good to set
goals; but as of
yet, there is no
reliable plan or
strategy. We
need to see
commitments to
specific details
for mandatory
emission
reduction
instead of
voluntary
incentives for
industry.
One of the first
regulatory steps CARB has required
is for
ships to use
cleaner-burning
fuels in their
auxiliary diesel
engines within a
24 nautical
mile range of the
California
coastline.
The ship's use
of cargo-handing
equipment such
as forklifts and
cranes will
result in replacing or
retrofitting
their engines.
The new
regulations,
which went into
effect on January 1, 2007 are
expected to cut
PM emissions by
a total of
23,000 tons, NO
emissions by
15,000 tons and
SO emissions by
200,000 tons by
the year 2020.
The U.S. EPA is
working on
reducing
emissions from
propulsion
engines on
oceangoing
vessels. In 2003,
the agency
adopted emission
standards for
new Category
Three Marine Diesel
Engines
installed on
vessels
registered in
the U.S. from January
1, 2004 onward.
The EPA also
intends to set
standards for
fuels used by
marine engines.
The Federal
Agency estimates
that with these
new regulations,
when fully
implemented by
the year
2030, will
prevent up to
12,000 premature
deaths, 15,000
heart attacks,
and 6,000 child
asthma-related
emergency room
visits
throughout the
United States.
Because issues
such as engine
emissions are an
international
issue, the IMO
is also framing
rules for
cutting down
shipping
emissions. The
rules include a
global cap of
4.5 per cent by mass on
sulfur content
of fuel oil and
recommends
the monitoring of
sulfur content
globally. The
IMO is also
encouraging
countries to
declare their
coastlines as
“SO Emission
Control Areas,”
where sulfur
content in fuel
must not exceed
1.5 per cent.
One of the
fastest and
most
expensive ways
to cut emission
fuel altogether
is to use
shore-port-to-ship power,
which is
called “Cold
Ironing.” This
process requires
ships plugging into
onshore power.
Ships will have
to be
retrofitted for
onshore
power systems,
and there would
be an expense
for updating
their power
systems.
Nearly 20 per
cent of
the ships
visiting
California ports
will use
shore-based
power by 2010.
This number
would gradually
go up to 80 per
cent by
2020 according
to CARB. The one
drawback is
that this process may
not be
economically
viable for
infrequent port
visitors.
Ports all over
the world
are starting to
offer terminals
with shore-port-to-ship power,
and cruise ships
are now setting
up all their
vessels for
shore power.
China has set up
their large
container ships
to use shore
power, and the Navy
has used this
method for
years.
Shore-port-to-Ship
power will be the
wave of the
future as nations
around the world
realize the need
to protect our
environment for
future
generations.
As this method
becomes global,
there will be
an
increase in the
use of
shore-port-to-ship
converters.
Because each
port will have
different
frequencies and
voltages,
converters become
the economical
solution. A TEMCo
Shore-Port-to-Ship
Power Converter
is a unique
frequency
converter that
performs
multiple
functions. It
provides the
possibility to
connect to any
shore-power
connection
anywhere in the
world ranging
from 25 kVA to
over 400 kVA.
Supplying power
is only half of
what this
converter does,
it also
stabilizes and
offers power
factor
correction.
