The Norwegian Jade and Norwegian Sun have been retrofitted with exhaust gas
cleaning systems.
The technology is used
to remove sulfur dioxide from a ship's engine exhaust, allowing ships to use lower-cost
fuel with a high sulfur content and still meet international anti-pollution
standards.
In each ship, five
scrubbers were installed, one per engine, covering the whole propulsion
system. Collectively, they are capable of reducing the emission of sulfur
to air up to 99% and also reduce 85% particulate emission to the air, Norwegian
Cruise Line said.
Counting the
Norwegian Bliss, which is scheduled to be delivered next April, Norwegian now
has eight ships outfitted with the scrubber technology. It said it is on
track to meet its goal under the MARPOL Annex VI regulations of reducing its
global sulfur cap from 3.5% to 0.5% by 2020.
