PortMiami Launches Shore Power, Reducing Emissions and Noise

In Miami, PortMiami recently celebrated the launch of shore power, a groundbreaking initiative allowing cruise ships to turn off their engines while berthed and plug into landside electrical power for all onboard functions, reducing emissions by up to 98 percent. The system is a collaboration between Miami-Dade County, Florida Power & Light Company, and major cruise lines MSC Cruises, Norwegian Cruise Line Holdings, Royal Caribbean Group, and Virgin Voyages.

The noise level from a berthed cruise ship can be significant, primarily due to engine and machinery noise, as well as onboard activities and entertainment. Measurements at various ports have indicated noise levels ranging from 54 to 60 decibels (dB) near residential areas adjacent to cruise terminals.

PortMiami is the first major cruise port on the U.S. eastern seaboard to offer shore power at five cruise berths. In the coming year, 21 cruise ships will be outfitted for shore power, connecting more than 350 vessel calls to the system. PortMiami’s $4.2 billion capital improvement program targets NetZero emissions.
