Royal Caribbean Cruises Ltd. (RCCL) will retrofit 19 of its
ships with exhaust scrubbers, which the cruise company says will remove more
than 97% of the sulfur dioxide emissions generated by the ships' diesel
RCCL said that the move will position it “ahead of all
forthcoming International Maritime Organization Emission Control Area emissions
standards, and will ensure compliance with existing European Union standards.”
Beginning in January, installation will take place on 13
Royal Caribbean International ships and six Celebrity Cruises ships, during
scheduled drydocks and while ships are in service.
Preliminary work has begun on several of the ships, RCCL
said, but most work will take place between 2015 and 2017. Each installation
will take approximately eight months.
Two ships that entered into service this year, Royal
Caribbean’s Quantum of the Seas and TUI Cruises' Mein Schiff 3, had scrubbers
installed during initial construction. Royal Caribbean's Liberty of the Seas
has been operating one of its six engines with a retrofitted scrubber system
for two years.
Royal Caribbean said the system "scrubs" exhaust
gases by injecting a high volume of water spray into the exhaust stream.
