Do cruise ships use jet engines?

Currently there are a total of six cruise ships in operation that use a combined gas turbine and steam turbine integrated electric drive system (COGES) plant based on GE’s LM2500+ gas turbines — two Royal Caribbean ships, Brilliance of the Seas and Radiance of the Seas, and four Celebrity Cruises ships, Millennium.

How do cruise ships generate electricity?

A diesel-electric engine connects to generators that provide electricity to turn the propellers and power the ship’s lights, appliances, air conditioning systems and more. Most modern cruise ships have several engines connected to generators. For example, Wind Surf has four diesel-electric generating sets.

Do cruise ships have to keep their engines running?

If you look at almost any cruise ship’s fleet, their ships are operating in warm lay-up somewhere around the world, with their engines running and crew onboard keeping the ship ready. But for now, cruise lines will keep the ships in warm lay-up.

Do cruise ships make their own electricity?

Nearly all contemporary cruise ships are powered by electricity (motors turn propellers). It powers the air conditioning systems, lights and all other appliances aboard the ship. Most vessels produce the electricity they need by using diesel engines. Some use gas turbine engines.

How many cylinders does a cruise ship engine have?

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.

What kind of motors do cruise ships have?

Cruise ship engine types The cruise industry has been around since the mid 1800s, when ships were propelled by steam engines. Modern cruise ships run on diesel engines, or more recently gas turbines introduced by Royal Caribbean as a greener alternative.

How long do cruise ship engines last?

Realistically, after about 30 years of a relatively efficient life, things start to happen. Normally, a cruise operator receiving a run-of-the-mill new ship will keep it and maintain for about 25 to 30 years.

What are the advantages of diesel-electric cruise ship engines?

The main advantage of the diesel-electric cruise ship engine systems is efficiency as they allow main engines to operate near the most efficient speed, no matter if the ship is moving at 5 or 25 knots. Losing electrical power is devastating to ships.

What kind of engine does a Carnival Cruise ship have?

The above photo is of the Vista-class Carnival cruise ship engine room. The engine type is “MAN 2 times; 14V48/60CR” (common-rail diesel injection system): All ships are supplied with emergency generators to maintain vital electrical power.

What happens when a ship loses electrical power?

Losing electrical power is devastating to ships. Main engines and generators require electricity and it’s needed to keep them going. Pumps that are driven electrically take in cold ocean water to cool the engines, and electrical pumps get fuel from fuel tanks and supply it to the engine.

How do ships generate power when they are docked?

While ships are docked, generators and main engines produce more power than needed. They are turned off in port, and smaller generators supply “hotel” load (lights, air-conditioning, galley, etc.).
