Mixed signals on cold ironing
Shipping’s reaction to cold ironing as a method of reducing emissions has
been mixed, not least due to logistical challenges, with some in outright
opposition to its usage, writes Clare Nicholls.

he drive towards cold ironing,
where ships in port cut emissions
by drawing on shoreside facilities
for power, is being pioneered at the
port of Los Angeles. Here, the port and
Nippon Yusen Kabushiki Kaisha (NYK
Line) recently announced their first
successful implementation of a ‘direct’
shoreside electric power connection
to a container vessel at berth. NYK
Atlas arrived at Yusen Terminals in
November 2007, and was connected to
a 6.6kV alternative maritime powered
(AMP) shoreside plant a few hours after
docking, utilising shoreside power until
its departure three days later.
‘NYK Atlas is leading us into the
next generation of clean, at-dock ship
operations,’ said Geraldine Knatz, NYK Atlas docked at the port of los Angeles in november 2007 and utilised shoreside

have been terrific partners in helping
the port of Los Angeles deploy AMP,
demonstrating their commitment early-
on by building AMP capability into
NYK Atlas.’
The ship is a post-Panamax container
vessel, and can carry 6200TEU. It
is 299.9m long, 40m wide, with a
displacement of 75,519gt.
NYK Atlas is the first of 38 NYK-
flagged vessels that will be equipped
to utilise shoreside electric power. This
follows another successful test of a
shoreside electric power unit onboard an
8600TEU NYK containership delivered
by IHI Marine United’s Aoio Shipyard.
