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.
