The ship’s power comes from six medium-speed, marine-diesel generating sets: three 16-cylinder Wärtsilä 16V46D common rail engines producing 18,480 kilowatts (24,780 hp) each and three similar 12-cylinder Wärtsilä 12V46D engines producing 13,860 kilowatts (18,590 hp) each.
How big are the engines on a cruise ship?
Since engines must power ships through the water, they can be immense for massive vessels. For example, a nine-cylinder engine designed for a large cargo ship might be 65 feet long, 60 feet high and weigh about 1,500 tons. An engine of that size would take up about one-fifth of Windstar’s small 148-guest ship.
How much fuel does a cruise ship burn per hour?
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.
Do cruise ships turn their engines off?
When ships are docked and not moving, main engines and generators produce far more power than needed. In port, they are turned off, and smaller generators are used to supply the “hotel” load (i.e., lights, air conditioning, the galleys, etc.).
Do sharks follow cruise ships?
Cruise ships move far too fast for sharks to follow them. Yes, a shark may have a burst speed that could match a ship, but not one that it could sustain. … Primary treated sewage is discharged in open ocean, granted, but ships do not leave a “trail” in which sharks would have any interest.
Do cruise ships dump their waste in the ocean?
U.S. law allows cruise ships to dump raw sewage in the ocean once a ship is more than three miles off U.S. shores. Ships can dump treated sewage anywhere in the ocean except in Alaskan waters, where companies must comply with higher state standards. … Cruise customers want strong actions taken to reduce ocean pollution.
How much do cruise ships pay for fuel?
A smaller-sized cruise ship like the Norwegian Spirit costs about $80,000 per day on fuel. A larger cruise ship like Freedom of the Seas can cost up to $2 million per day to fuel.
How much does it cost to fill a cargo ship with fuel?
With the cost of bunker fuel at $552 per ton, and with fuel consumption of 217 tons per day, a single 28-day round trip voyage for this one vessel would produce a fuel bill of $3,353,952.
