Air pollution
from trade and
goods movements
has become a
major health
concern. The
emissions and
associated
health impacts
are greatest in
regions with
major ports.
California and
Seattle, just to
name a few
ports, have set
up programs to
reduce air
pollution in a
number of
different ways.
The health
impact of these
pollutants near
large ports is a
major concern.
These pollutants
can cause
premature deaths,
respiratory
problems,
cardiovascular
issues,
asthma and other
lower
respiratory
symptoms. Just
in California
alone, they
estimated that
the annual
statewide deaths
that can be
associated with
exposure to
ozone and
particulate
pollution is
around 9,000.
About 70 percent
of the potential
cancer risk from
toxic air
contaminants in
California is
due to diesel
PM. The largest
contributors to
cancer risk were
cargo handling
equipment and
ships using
diesel engines
at dock while at
call. While
ships in transit
produce a
substantial
portion of total
port-related
diesel PM, they
did not produce
a comparable
cancer risk
because these
emissions are
released
off-shore and
dispersed over a
very wide area.
When at port,
ships'
emissions of Nox
and fine
particulate
matter (PM) also
contribute to
regional ozone
and to local
health risks.
Repeated
exposure to
these emissions can make
people more
susceptible to
respiratory
infection and
lung
inflammation and
can aggravate
pre-existing
respiratory
diseases.
Exposure to
diesel PM can
also be linked
to premature
death and a
number of heart
and lung
diseases.
As set forth by
the ARB Board on
April 20, 2006,
California's five
specific goals
for addressing
the air
pollution
associated with
goods movement
are:
-
Reduce total
statewide
international
and domestic
goods
movement
emissions to
the greatest
extent
possible and
at least
back to 2001
levels by
year 2010.
-
Reduce
the
statewide
diesel PM
health risk
from
international
and domestic
goods
movement by 85
percent by
year 2020.
-
Reduce NOx
emissions
from
international
goods
movement in
the South
Coast by 30
percent from
projected
year 2015
levels and
50 percent
from
projected
year 2020
levels based
on
preliminary
targets for
attaining
federal air
quality
standards.
-
Apply the
emission
reduction
strategies
for ports
and goods
movement
statewide to
aid all
regions in
attaining
air quality
standards.
-
Make
every
feasible
effort to
reduce
localized
risk in
communities
adjacent to
goods
movement
facilities
as
expeditiously
as possible.
Shore-side power
or “cold ironing”
has become an
important part
of reducing
these air
pollutions. While
ships are
plugged-in to
shore-port-to-ship
power, they
would produce
zero emissions.
That would
eliminate more
than 1,000
pounds of
exhaust
pollutants in a
single
containership
port call. In
April of 2006, CARB identified
“cold ironing”
as a strategy to
reduce
emissions with
a goal of a 20
percent
reduction by
2010, 60 percent
reductions by
2015 and 60
percent
reductions by
2020. This
timeline is not
nearly
aggressive
enough for
California to
meet its clean
air goals.
Using cold
ironing is not a
new technology,
the U.S. Navy
has been using
shore-side power
for quite some
time for their
ships and
nuclear
submarines. Large
commercial
shippers around
the world are
beginning to use
cold-ironing,
realizing that
the technology
is more cost
efficient in the
long run.
As this method
becomes global,
there will be an
increase in the
use of
shore-port
to-ship power converters.
Because each
port will have
different
frequencies and
voltages, a
converter becomes
an 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.
