How Big Is A Cruise Ship Gas Tank

They need 6 times more space.

How big is a cruise ship gas tank. For comparison a private motor yacht between 40 and 60 feet only carries 200 to 1200 gallons while something massive like the Exxon Valdez carries up to 55 million gallons. To save hull space LNG tanks are located on an open deck. For example the QE2 consumes about 380 tons of fuel daily if its traveling at a speed of 285 knots and carries enough fuel to sail nonstop for 12 days source.

Consuming that much fuel at top speed Mariner of the Seas burns a staggering 104 gallons just to go one mile. A large cruise ship ranging in length from 900 to 1100 feet might hold 1 to 2 million gallons of fuel. To put these figures into perspective consider a typical jetliner.

OTOH walking provides 360 miles per gallon and biking is 700-47k miles per gallon depending on aerodynamics of. The Boeing 747-400 seats 624 cruises at 567 mph and has a range of 8357 miles. He said the big difference is in the space needed for onboard fuel tanks and the thick insulation required.

If there is an issue with the spec the cruise company wont pay for the fuel and sometimes it can even go to court. When ships come into port they take the opportunity to fill up the fuel tanks. Distillates also power most auxiliary engines on all ship types although some larger vessels will use IFO when possible.

On average a large cruise ship can use up to 250 tons of fuel per day which is around 80000 gallons. Its main salon measures 29m in length with its beam measuring 18m. MAN said the computer simulations and theoretical studies found only one real challenge for building straight engines with as many as 18 cylinders and pistons with a bore as wide as 1200 mm.

All six wartsila main engines of the cruise ship oasis of the seas are having heavy fuel consumption of 2400 gallons per hour. WarwickCruise ships usually fill up at various ports using fueling barges like floating gas stations. For smaller vessels it is about 6000 barrels.
