The future of cruise propulsion: Increasingly, LNG fuels newbuilds: Travel Weekly

The output shafts, to produce electrical power, are connected to generators. If a port is planning to provide an onshore power supply (OPS), how much electricity will it need and where will it come from? Cruise ships are particularly power-hungry, thanks to their large hotel loads. CLIA members are committed to working with ports and local authorities to support these projects. So far, however, more cruise ships are equipped with shore power connections than there are ports internationally that offer this option. CLIA is encouraging all ports to consider equipping their cruise berths with this capability, to the benefit of their local population and to support the decarbonisation of the maritime sector.

Older cruise ships may still use a diesel reciprocating engine to generate enough power to move them. Power is supplied to the ship through a transmission going to a propeller shaft. Storage requirements on board for LNG require very large tanks, so this type of fuel is most commonly being used on smaller ships that don’t travel as far, like ferries. But as the technology improves, it should start to be seen on larger cruise ships.
Hybrid Electric Systems:
The mechanics are the same; the main difference is how the power is created. Instead of steam making the pistons go up and down, the ignition of fuel now creates pressure and pushes the pistons up and down, turning the crankshaft connected to a propeller shaft. The pistons were connected to a crankshaft, which turned the vertical motion of the pistons into a rotational movement. The crankshaft was directly connected to the propeller through a long propeller shaft. The faster the pistons on the engine moved up and down, the faster the propeller shaft turned and the faster the ship went.

Rebuilds, he said, wouldn’t be as costly or take as long as converting the ships entirely to nuclear power. “Think of the vessel as having two parts—propulsion, and the rest of the ship. It would be possible to refit the ships with nuclear just to power [a ship’s] onboard electricity needs,” noted Menzies.
This process, called bunkering, is a whole-team effort and is completed before the ship is ready to travel again. There are abundant space and a deluxe ship that will greet you as a valued guest from beginning to end for the high price. No doubt, one will fall for such an exquisite experience that starts from fine dining of caviar and foie gras to personal service available at one’s fingertips. Depending on your opinion and type of cruise you may have signed up for, you may think that your cruise is way under or over-budget.
What Is LNG Gas, and What Are LNG-Powered Cruise Ships?
This results in fewer cabins and a resulting reduction in guest capacity. The major advantage to incorporating LNG is that the released gas combustion significantly reduces carbon oxide, nitrogen oxide, and sulfur emissions into the air. “It is a relatively new industry, and the LNG carrier modelis very safe but comes at a cost,” U.S.
Traditional Diesel Engines are Simple
Additionally, LNG is a cleaner-burning fuel compared to traditional marine fuels. The choice of engines for cruise ships is a critical decision that takes into consideration factors such as power requirements, fuel efficiency, environmental impact, reliability, and safety. Over the years, there have been significant advancements in cruise ship engine technology, leading to the emergence of more sustainable and innovative options. By connecting to shore power, cruise ships can significantly reduce their fuel consumption, emissions, and noise levels while in port. Instead of running the ship’s diesel generators continuously to meet power demands, the ship can tap into the local power grid, which is often more environmentally friendly and cost-effective. When ships are docked and not moving, main engines and generators produce far more power than needed.
Cruise ships are marvels of modern engineering, offering unforgettable experiences on the high seas. As these magnificent vessels sail across oceans, powering their immense size and providing luxurious amenities to passengers requires robust and efficient engines. The engines used in cruise ships are not only responsible for propelling the ship but also for generating electricity, providing heating and cooling systems, and supporting various onboard facilities.
Generally targeting a niche group, most luxury cruise lines do not allow children. That being said, if you are looking to book a trip, be on the lookout for green cruising opportunities! Onboard, you can also find environmentally conscious crew members and less-waste policies. As cruising, which is the fastest growing tourism sector, continues to grow and green travel continues to emerge as a trend, travelers can more easily find options that appeal to their interests and values. Once travelers understand what it is they desire from a cruise, be it shopping, food, spas, time on the beach or local, authentic experiences, the best cruise line can be chosen. Although the ship would not be able to travel at normal speed, it would be able to navigate without the assistance of tugboats.
Engine manufacturers continually innovate and improve designs to enhance reliability and integrate the latest safety features, aligning with the industry’s commitment to providing a safe and enjoyable cruising experience. The engines must comply with stringent safety standards to protect passengers, crew, and the ship itself. Safety features such as automatic shut-off systems, fire suppression systems, and sophisticated monitoring and control systems are integrated into modern cruise ship engines. Diesel engines are the most commonly used type of engines in cruise ships due to their efficiency and reliability. These engines operate on the principle of internal combustion, where fuel is injected into compressed air, leading to combustion and the generation of power. In this article, we will explore the importance of engines for cruise ships and the different types of engines used in these vessels.
These are interesting questions, even for the non-mechanically inclined. Cruise Hive was established back in 2008 and among the earliest blogs in the industry. Since the start, it's been our aim to provide the latest cruise news covering all the major cruise lines. We make sure cruisers are fully prepared for their cruise vacation with tips on ships and ports.Millions of travelers rely on Cruise Hive in the United States, Europe, Australia, and around the world. It takes numerous engines to move something that is so massive in size and weight. Combine that with the horsepower required to make it move, and you also appreciate the cruise ship’s knots.
Their high efficiency, flexible power output, and lower emissions make them a notable choice for cruise lines seeking to optimize energy usage and reduce their environmental footprint. The choice of engine depends on factors such as power requirements, fuel efficiency, operational costs, and environmental impact. Cruise ship operators carefully consider these factors to select the most suitable engine type for their specific needs, ensuring optimal performance and a memorable experience for passengers. Without efficient and reliable engines, cruise ships would be unable to function effectively. The engines not only determine the speed and maneuverability of the ship but also ensure the seamless operation of all onboard systems.
A small amount of enriched uranium emits heat, which is used to drive a steam engine that can power a ship’s propulsion and onboard electricity. That small amount of uranium can power the ship for decades before it’s spent, freeing up space on the ship that would normally be used to carry conventional fuel. Nuclear power produces no greenhouse gas emissions, so replacing a fossil fuel–burning ship with a nuclear-powered one effectively cancels that ship’s carbon output. Most cruise ships have medical centers with doctors and nurses onboard. You can visit the medical center if you get sick or injured during your cruise vacation, or to obtain things like bandages and seasickness medication.
