What is the fuel consumption for a cruise ship at berth?

The fuel consumption for a cruise ship at berth generally ranges from 0.5 to 2.0 tons of fuel per hour, depending on the size of the ship and its onboard services. This consumption is primarily due to auxiliary engines powering lights, air conditioning, and other amenities while the ship is docked. To reduce emissions and fuel usage, many modern cruise ships utilize shore power connections when available.
