NCL recently announced that they will be retrofitting six ships with exhaust scrubbers. This is a technology whereby the exhaust is essentially scrubbed of sulfur oxides by running it through seawater before venting it through the funnel.
The company has contracted with Green Tech Marine for the outfitting of the scrubbers on Norwegian Breakaway, Norwegian Dawn, Norwegian Jewel, Norwegian Gem, Norwegian Pearl and Norwegian Sun.
The Pride of America has already received hers during a drydock last year. The newbuild Norwegian Escape and Norwegian Bliss will also feature these scrubbers when they’re launched .
