At full power, they would burn around 1,377 gallons of fuel per hour, or about 66,000 gallons a day of high-polluting diesel fuel.

Cruise ships are not designed to be able to refuel while they are out at sea and it is incredibly unlikely that a cruise ship would run out of fuel and be unable to find somewhere to dock to refuel. If this did happen the passengers and crew would have to be evacuated either using lifeboats or by air.
During a typical one-week voyage, a large cruise ship (with 3,000 passengers and crew) is estimated to generate 210,000 US gallons (790,000 L) of sewage; 1 million US gallons (3,800 m3) of graywater (wastewater from sinks, showers, and laundries); more than 130 US gallons (490 L) of hazardous wastes; 8 tons of solid ...
If we do some more math, we can calculate how long it takes to refuel a cruise ship entirely. A cruise ship can be refueled at about 3,500 gallons per hour. Applying this to an average small vessel — which holds about 130,000 gallons of fuel — it would take almost 40 hours to completely fill it up.
A large cruise ship ranging in length from 900 to 1,100 feet might hold 1 to 2 million gallons of fuel. Smaller vessels, like a 440-foot-long ferry, might carry around 130,000 gallons of fuel, while a gigantic ship measuring over 1,300 feet in length can tote over 4 million gallons.
Diesel Electric.New cruise ships feature diesel electric propulsion. So rather than being connected to the propeller shafts, the main engines are connected to large generators in order to produce electricity. This electricity is sent to electric motors, which powers the propellers and moves the ship.
it can vary significantly depending on factors like the cruise line, ship size, passenger capacity, itinerary, and operating expenses. Profit margins in the cruise industry typically range from 10% to 20% of revenue, but these figures can fluctuate from year to year and across different cruise companies.
The kitchens are extra enormous.A ship that carries 3,500 passengers uses 600 pounds of butter per day, 250,000 eggs per week, and 170,000 pounds of fresh fruits and vegetables per cruise. Naturally, there are more hands on deck in the kitchen too.
It comes as no surprise that the ship's captain has the biggest salary from working on a cruise ship. The master of the vessel has a huge responsibility for ship safety for crew and passengers along with navigation. The captain can earn almost $100,000 manually depending on the cruise line and experience.
Tip: Unlike hotel prices, cruise fares are listed per person, not per cabin, with rates based on two people occupying a stateroom. Cruise lines offer single travelers the opportunity to book a double cabin for themselves by charging a “single supplement,” which is basically 1½ or 2 times the list price for one person.
Generally, the highest-paying jobs on cruise ships are held by officers, department heads, and those working on commission. However, many other variables affect earning potential, such as cruise line, ship size, clientele, tips awarded, and prior job experience. Contracts are another factor.
Larger vessels may travel faster at anywhere from 21 to 24 knots. Royal Caribbean states that the average speed of their cruise ships is 18 to 20 knots. Cruise ships typically slow down as they approach the shore. That said, the top speed of a vessel would be around 30 knots, which is about 35 miles per hour.
While there's a romantic idea of ships being powered by steam, cruise ships are powered by diesel engines as standard. There are three methods: direct drive, diesel electric or gas turbine. Direct Drive. The conventional diesel method is the simplest.
