The latest advancement in becoming more environmentally responsible is the introduction of LNG-powered cruise ships. As technology continues to advance, further improvements are being made in the efficiency and energy storage capabilities of hybrid electric systems. This, coupled with ongoing advancements in battery technology, will pave the way for even more efficient and environmentally friendly cruise ship operations in the future. Emissions from cruise ship engines contribute to air pollution and climate change. Key pollutants include sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter.

Cruise is a Key Regional Industry
For other countries, your best bet is exchanging cash at a bank before you even board the ship. Shore excursions desks are often located near the guest services desks. Here, passengers can choose from ship-sponsored activities available onshore at the various ports.

In July 2021, the European Commission put forward some legislative proposals, called the ‘Fit for 55’ package, to achieve the first of those targets and, for shipping, these will require investment in OPS. In the years to come, ports in some regions of the world will be required to provide an OPS, so the questions posed at the start of this article cannot be ignored. This fuel source has a lower fuel density than other gases, meaning fleets that make the shift require twice the tank space.
Power and Engines
(The last passenger ship built with a steam engine -- Sitmar's FairSky in 1984 – was scrapped in 2013.) Today, diesel engines are the standard. Sitting contentedly on deck, listening to the hushed splash of the sea as it washes along the side of the hull, you would be forgiven if you forget you are on a monster of engineering. At that very moment, deep in the bowels of the ship, small armies of engineers (and an awful lot of computers) are working to keep the lights on, the air conditioning cooling, the toilets flushing and the propellers turning.
Cruise lines have "guest services" desks, which provide a service similar to what you'll get from a front desk clerk at a hotel. For the most part, there's no true concierge available to all passengers (exceptions are some high-end cruise lines and river ships). Otherwise, many suite passengers have access to private concierges, who can assist with dinner and spa reservations and the like, while some luxury cruise staterooms have butlers that perform those functions. After the launch of these ships, other cruise lines moved toward using this fuel. By reducing carbon emissions, it generated a heightened awareness toward the industry’s green practices, making it a welcome shift for consumers. Engines that are designed to use LNG fuel require less maintenance because there is less wear on the engine.

The main difference is the source of pressure, which can be the traditional steam, or a fuel ignition. Reversing can be achieved either by reversing the propeller rotation or by rotating the pods 180 degrees. The latter helps to reverse the vessels without the need to reverse the prime-mover. A hydraulic steering unit aids in the 360 degrees turning capability which is useful during maneuvering. It is especially applied in many cruise destinations having smaller ports and limited tug assistance. The AZIPOD is the first diesel-electric podded propulsion that is capable of azimuthing through 360 degrees.

They also use three 12-cylinder Wartsila 12V 46D engines to power the ship. Medium-sized ships will require 150 tons per day and as size decreases, fuel consumption does as well. Without a cruise ship engine, these vessels would be nothing more than a floating hotel. They would drift aimlessly at sea and would lack any form of propulsion.
Environmentally Friendly Power
They are designed to operate continuously for extended periods, ensuring a constant and uninterrupted power supply to the ship’s systems and amenities. Cruise ships often have multiple diesel generators to provide redundancy, meaning that if one generator fails, the others can seamlessly take over and prevent any disruptions in power. Now that we have explored the various power sources on a cruise ship, let’s dive deeper into the power distribution system and understand how the electricity is distributed throughout the vessel. So, how does fuel play a part in powering the engine and the cruise ship? An engine generates electricity to the propellers by supplying power the propulsion motors. Most likely fuel and ignition (besides the steamboat example from before).
Already, 35% of the global capacity of cruise ships is equipped with shore power connections. However, less than 20 ports worldwide currently provide shore power for large cruise ships – three of these are in Germany. The most noteworthy is the engine requirements the cruise ships need to run on this fuel. Therefore, ships must be designed using a specific engine that holds LNG and will correctly burn the fuel. This trend began with implementing changes onboard, such as eliminating or reducing the use of single-use plastics, retrofitting or building ships to reduce overall emissions, and providing composting and recycling onboard.
Through delivering the project, ABP has learned many valuable lessons, including the importance of suitable port infrastructure, power and funding. A more immediate source of green electricity in Europe is likely to come from enhanced wind power provision in the North Sea. In April, five European energy ministers signed the ‘Ostend Declaration’, supporting four other nations that signed up in May last year. The industry encourages port authorities to invest in sustainable shore power infrastructure as well and that shore power is produced from green, renewable sources. After Carnival Corporation’s success with LNG fuel, other cruise lines followed their example. Disney Wish is the first ship in the Disney Cruise Line fleet to use the new fuel to power their propeller system.
The power distribution system on a cruise ship is responsible for routing electrical energy generated by various power sources to the different systems and amenities on board. It ensures that electricity is distributed efficiently and reliably throughout the vessel, meeting the diverse energy needs of the ship. Additionally, integrating battery banks with other renewable energy sources, such as solar panels, can further enhance sustainability and reduce environmental impact. Excess solar energy can be stored in the battery banks for use at night or during periods of limited sunlight, reducing reliance on diesel generators. One of the primary benefits of battery banks is their ability to smooth out power demand fluctuations and optimize energy usage. During periods of low power demand or when the ship is at port, the battery banks can supply electrical energy, reducing the need to run the diesel generators continuously.
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.
Efforts to improve fuel efficiency also extend to operational practices. Cruise ship operators implement measures like optimized routing, reducing speeds, and implementing energy-saving technologies onboard to maximize fuel efficiency. These practices, combined with fuel-efficient engines, can have a significant impact on fuel consumption and emissions. Engine selection for cruise ships is a complex process that involves evaluating and balancing various factors.
The power generated by the main engines/powerplant produces electricity that is used from the propulsion motors, as well as all auxiliary systems and hotel functions. This innovative maritime technology allows the engines to be started and stopped depending on the onboard electricity demand, which additionally improves fuel efficiency. The four newbuilds became the industry's first LNG (Liquefied Natural Gas) powered vessels using LNG in their hybrid engines. The gas is stored in the ship and used to generate all needed power at sea. The engines are not exclusively LNG, but "dual fuel" (capable of burring both liquid marine fuel and natural gas).
An emergency generator is also available as per SOLAS, located above the uppermost continuous deck and away from the machinery spaces. This must start and come on load within 45 seconds of a power failure and supply power to the emergency switchboard. The switchboard provides power to selected critical equipment during blackout. Due to their large size, they command a separate compartment in the ship’s machinery space.
The main region for cruising was North America (70% of cruises), where the Caribbean islands were the most popular destinations. This means that if the cruise ship is registered under another country, they can never directly stop at an American stop if their initial take-off was in the United States. Not necessarily detours or emergency stops, but maybe a cruise led you to Ensenada or the Tabuaeran. Most of the crew members are working very long hours for several months. Many corporations own several of these different targets to make the most profit. Additionally, by corporations owning various cruise types, they can also hand down older ships throughout their other brands.
