Royal Caribbean Cruises Ltd. 23
The company continues to explore prototype systems through research and development, as was done with General Electric
for the gas turbines and with a Swedish manufacturer for Marinfloc, a bilge-water cleaning system installed fleetwide in 1998-
99. Marinfloc uses aluminum chloride to break up emulsions in a process called flocking, so that processed bilge water is at
least three times cleaner than the international standard.
Some of the chief accomplishments in 2001 included:
Increasing fuel efficiency through system upgrades, enhanced maintenance routines, and energy conservation. This resulted
in savings of 17,500 tons of diesel fuel, equivalent to a train of 700 tank cars spanning more than nine miles.
Reducing exhaust emissions by optimizing engine performance, using fuel additives, and implementing an advanced fuel
polarization system. NOx emissions were lowered by 23 percent, earning Celebrity Cruises the Environmental Protection
certificate from Lloyd’s Register.
Re-piping the photo labs to create a “closed loop” operation of silver recovery units. By removing silver from photo waste,
effluent becomes non-hazardous.
Installing a filter system in laundry rooms to remove perchloroethylene (PERC) from any liquid waste in the dry cleaning
and steam-press process. The filtered effluent can be landed as non-hazardous.
Eliminating 99 chemicals from a list of approved chemicals as part of ongoing improvements in chemical management.
Replacing Sterno, used for warming a chafing dish, with the odorless Ecofuel, which contains no alcohol and no air pollu-
tants, has a lower flash point, and is self-extinguishing when inverted.
Using water-based printing plates instead of plates that required a chemical printing solution.
Having made my living from the sea for more than 30 years, it gives me great pride in knowing that whether through
technological advances or best practices, Royal Caribbean International and Celebrity Cruises strive to set the standard for
environmental stewardship.
