How Does A Cruise Ship Get Electricity?

Cruise ships are equipped with multiple diesel generator sets to meet their power demands, which are larger and more powerful than traditional generators. These generators rely on onboard generators fueled by diesel or natural gas to produce electrical power. Port facilities provide infrastructure for cruise ships to connect to the power grid.

Cruise ship engines are large and require their own space, typically located on the lowest deck. Ship designers have historically put the engines in the engine room, which is usually located on the lowest deck. Modern cruise ships use electric motors and huge diesel generators to supply power to sailing and hotel loads. Once docked, only a few cruise ships use electric motors and diesel generators to supply power to the sailing and hotel loads.

Cruise ships require a lot of power, as they carry close to 3000 passengers with 500-1000 crew members at any time. Most modern cruise ships are diesel-electric, with big-ass diesel engines that produce electricity. Some of this electricity goes toward propulsion, while the rest goes towards the ship’s electrical system. Cruise ships also use gas turbines, although they use a non-renewable energy source, making them a greener alternative to traditional cruise ships.

The main engines are generators that produce electricity, which then powers the azipods. Power is transmitted from an on-shore transformer to the ship through five flexible electrical cables that connect to the ship’s electrical system.

How does a ship generate electricity?

Power generation On board Shipboard power is generated using a prime mover and an alternator working together. For this an alternating current generator is used on board. The generator works on the principle that when a magnetic field around a conductor varies, a current is induced in the conductor.

A ship is like a floating city with all the privileges enjoyed by any normal land city. Just like a conventional city, the ship also requires all the basic amenities to sustain life on board; the chief among them is power or electricity. In this article we will learn as to how power is generated and supplied on board a ship.

Shipboard power is generated using a prime mover and an alternator working together. For this an alternating current generator is used on board. The generator works on the principle that when a magnetic field around a conductor varies, a current is induced in the conductor.

The generator consists of a stationary set of conductors wound in coils on an iron core. This is known as the stator. A rotating magnet called the rotor turns inside this stator producing magnetic field. This field cuts across the conductor, generating an induced EMF or electro-magnetic force as the mechanical input causes the rotor to turn.

How much electricity does it take to power a cruise ship?

4: Fuel cells show energy-saving potential for cruise ships. Traditional cruise ships need 10–100 MW of power for propulsion, lighting, air conditioning and on-board amenities. Today, it is usually generated by on-board diesel or gas generators, though some ships can now take shore power at some ports.

Fuel cells, a clean power-generation technology when produced from renewable energy sources, are already used on land for applications like data centres. Some cruise ship owners are piloting on-board 1–5 MW fuel cells to further explore their potential to boost energy efficiency and reduce emissions.

The future energy-saving potential of fuel cell technology in maritime applications, particularly for cruise ships, is significant. This potential is derived from several key attributes of fuel cells compared to conventional marine propulsion and power generation systems, including higher efficiency by direct conversion of fuel to electricity, reduced energy waste, zero emission potential and enhanced operation flexibility.

How are cruise ships powered now?

How the ship moves. 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. The ignition of fuel creates pressure that pushes the pistons up and down. The pistons turn the crankshaft, which is connected – via gears – to the propeller via a long shaft. The gears allow the engine to turn at its fast speed, while allowing the propellers to turn at their much slower speed. With this method comes the option to use a shaft generator, which uses the circular motion of propeller shaft to generate electricity for cooking and lighting, etc. However, by design, shaft generators can be used only while the ship is moving.
  • 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. Around 85% of the power goes towards the propellers while the rest is distributed around the ship to cabins, restaurants and entertainment via hundreds of kilometres of cables.
  • Gas Turbine. A greener option than diesel engines, gas turbines are used to drive generators that then provide electricity to the propeller motors. Using heat from the gas turbine’s exhaust, the steam turbine produces electricity for onboard services. The first cruise line to fit its ships with gas turbines was Royal Caribbean.

Staying powered up in the port. When the ship stops moving, the massive amounts of power from the main engines and generators aren’t required. Instead, the ship uses smaller generators to supply enough power for the lights, air-con and so on.

How do cruise ships get their power?

Engineers: Cruise ship engines are located near the bottom of the ship as they are heavy, and they are usually towards the aft of the ship. Cruise ships use Diesel-Electric propulsion systems. The main engines are generators which produce electricity which then powers the azipods. VV ships have 4 engines and 2 azipods. There are 3 bow thrusters to provide maneuverability when arriving/departing a port.

Azipods are a motor with a built in propeller and rudder. The electrical power created by the engines drives this big azipod motor which turns the propellers, and pulls the ship forward. Basically think of how a jet engine pushes air across a plane wing — that’s how an azipod and propeller pushes water across the rudder and drive/steer the ship. They can turn 360 degrees for maneuverability, and the rpm of the propeller varies depending on the required ship speed.

People tend to imagine engine rooms looking like the one on Titanic, with sweaty laborers shoveling coal into the engine. What does a cruise ship engine room actually look like?

What happens if the power goes out on a cruise ship?

If the main electrical power source is lost, we have plans for a contingency and we move to using the emergency generators. These are typically located on the upper decks and they have their own fuel supply and are completely independent. The generators can provide emergency lighting, fire detection systems, operate elevators and even provide power to re-start the engines, if necessary. They can also power communication channels – radio, telefax, email, so the ship can continue to communicate with shoreside.

Can cruise ships become electric?

Hurtigruten, a Norway-based cruise company, first announced its plans to create a fully electric passenger vessel in early 2022. Now the company has released an actual prototype of the ship and more details on how it will operate when it launches in 2030.

The futuristic, zero-emission ship, which will include 270 cabins that can sleep up to 500 guests, will be powered by electric batteries that charge when the ship is in port. Gerry Larsson-Fedde, senior vice president of marine operations for Hurtigruten Norway, estimates it will have a range of 300 to 350 nautical miles (about 345 to 403 land miles). It will also have retractable sails covered in roughly 16,150 square feet of solar panels that will help reduce reliance on the batteries when it’s windy. The high-tech sails will be telescopic, compressing to fit under bridges, and they will be able to change angles to best catch the wind.

The “Sea Zero” project is being carried out in collaboration with Norway’s Foundation for Scientific and Industrial Research (SINTEF) and various experts in finding technological solutions needed to achieve emission-free sailing.
