Cold Ironing
Requirements
Cold Ironing
Requirements to
Converting
Vessels and
Ports to Cold
Ironing
Ships and
vessels from
around the world
visit ports,
these
vessels'
electrical power
and voltage
requirements
vary from
country to
country.
To give a
example, most
ocean -going
vessels have
440-480 V. Large
container ships
and passenger
ships are
configured for
6.6 kV. The
larger and newer
cruise ships are
configured for
11kV. Newer
container-ships,
which are larger
are using 6.6
kV. These
various voltage
requirements
present problems
when designing a
cold ironing
facility. A
solution for
this is a
cold ironing
electrical
converter to
increase or
decrease the
voltage in ship.
The challenge is
where to place
the converter,
on the ship or
wharf.
Location of
the Converter
for Cold Ironing
Requirements
The Cold Ironing
Electrical
Converter can be
added to the
wharf or the
ship, but the
problem is
enough space and
should the port
provide the
converter or
should each ship
be equip with a
converter. Many
new cruise ships
and other
vessels are
building the
vessels to
accommodate
converters. It
would be much
less expensive
if there would
be just one
converter on a
wharf for all
ships to use.
Space is another
key issue when
placing these
converters for
cold ironing
requirements.
The Port of
Los Angeles is
considering
having a
converter
enclosed in a
container and
stored on the
wharf. This
would eliminate
the need for a
cold ironing
electrical
converter on
each ship, but
the ship still
needs a
allocated space
for the
converter
container when
used in port. If
cold ironing
requirements put
the converter on
the wharf, there
can be many
obstacles on a
wharf that will
limit where a
converter can be
located. Cargo
and containers
are stored on
the wharf while
being loaded or
unloaded from
the ship, also
trucks and
cranes are used
to load and
unload
containers and
other cargo from
a ship occupy
space.
Typically, only
three feet of
clearance is
available from
the rail on the
pier to the
water's edge.
Additional Power
needed for Cold
Ironing
Requirements
The port's
existing power
infrastructure
may not be
sufficient to
provide the
additional power
load that would
be needed
for cold
ironing
requirements.
The ability of
electrical
utility
companies to
provide the
additional power
load with the
preexisting
substation and
power lines at a
port will vary
from site to
site. Ports will
have to work
with local
utilities to
design and
install power to
meet additional
power demands
from cold
ironing ships at
their terminals.
Cables used for
cold ironing
must be stored
when ships are
not connected to
the port power.
These cables and
the reels that
house the extra
lengths of cable
must be stored
either at the
dock or on the
ship. As with
converters,
having enough
space is an
issue.
Cold Ironing
even with these
technical
problems is
proven to be
technically
feasible.
Cold-Ironing
Requirements are
now part of many
ports' efforts
to reduce
pollution and
reduce the
health issues
impacting
the communities
that surround
these ports.
Cold Ironing and
plugging in to
shore ports is
currently being
used or planned
for cruise
ships, container
ships, oil
tankers. The
Port of Los
Angeles is
installing or
planning to
install several
more
shore power
sites. The
Port of Long
Beach is adding
cold ironing
requirement
for future lease
conditions.
Seattle already
has terminal
with shore power
and adding more.
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 Cold Ironing
becomes global,
cold ironing
electrical
converter will
be a economical
solutions for
the different
frequencies and
voltages of each
port. A
