How much fuel does a cruise ship burn whilst in port?

While in port, a cruise ship typically consumes about 30-50% of the fuel it would use while cruising, depending on its size and the activities taking place. Fuel consumption is primarily driven by the need to power auxiliary systems like generators, air conditioning, and hotel services for passengers. On average, a large cruise ship might burn around 2-10 tons of fuel per day while docked. However, some ships utilize shore power connections to reduce fuel use and emissions while in port.
