The cost of fuelling a cruise ship is a complex issue influenced by various factors. The price of fuel, fuel type, ship size, sailing length, and speed all play a role in determining the overall cost. While bigger cruise lines generally incur higher fuel expenses due to larger ships and more frequent sails, the cost to fuel a cruise ship can range from $80,000 to $200,000 per day. With environmental concerns in mind, newer cruise ships are increasingly adopting liquified natural gas (LNG) as a cleaner alternative to traditional diesel engines, but this shift comes with its own set of challenges, including lower fuel density and increased fuel costs due to global conflicts.

Fuel costs range from $80,000 to $200,000 per day
The cost of fuelling a cruise ship is a highly variable figure, depending on a multitude of factors. The fuel costs for a cruise ship range from $80,000 to $200,000 per day.
The first factor is the size of the ship. Larger cruise ships will require more fuel to reach certain speeds due to the power needed to propel the vessel forward. A larger ship will also have a larger fuel tank, with some of the biggest cruise ships holding upwards of four million gallons of fuel. In contrast, smaller cruise ships may only be able to hold 100,000 gallons of fuel.
The length of the sailing is another significant factor. The longer the sailing, the more fuel the cruise ship will consume. Cruise ships can sail for 10 to 14 days before refuelling, but this depends on the size of the ship, the number of days spent at sea, and the fuel efficiency of the ship. The speed of the ship is also a major factor, as the faster a cruise ship goes, the more fuel it burns.
The type of fuel used is also important. Many newer cruise ships are powered by liquified natural gas (LNG), which burns cleaner than traditional diesel or gas-powered engines. However, LNG fuel has a lower fuel density than diesel. Cruise ships also use a significant amount of fuel to power air conditioning, water production, waste processing, and other functions that would typically be covered by a regular power grid on land.

Fuel capacity: Large ships hold 2 million gallons, small ships 130,000 gallons
The fuel capacity of a cruise ship depends on its size and class. Small cruise ships, typically measuring around 400 to 500 feet, can hold approximately 130,000 gallons of fuel, sufficient for shorter voyages. In contrast, medium-sized ships ranging from 900 to 1,100 feet have capacities of 1 to 2 million gallons.
Large cruise ships, such as Royal Caribbean's Harmony of the Seas, can carry up to 1.33 million gallons (about 5 million litres) of fuel. This allows them to operate efficiently over long distances while accommodating thousands of passengers. Mega cruise ships, such as the Oasis-class vessels, typically hold around 1.33 million gallons (approximately 5 million litres) of fuel.
The fuel capacity of a cruise ship is vital for its operations, as it determines how far the ship can travel without refuelling and impacts the overall itinerary. Cruise ships consume a significant amount of fuel, with a large ship burning up to 250 tons (over 80,000 gallons) of fuel per day. Smaller vessels typically consume around 140 to 150 tons daily. The speed of the ship also affects fuel consumption, with higher speeds requiring more power and fuel.
Cruise ships are designed to balance passenger comfort and entertainment, but this often results in higher fuel consumption compared to other maritime vessels. The large amount of fuel required by cruise ships has led to concerns about their environmental impact, with newer ships adopting liquified natural gas (LNG) as a cleaner alternative to traditional diesel engines.

Fuel type: LNG burns cleaner than diesel
The cost of fuelling a cruise ship depends on various factors, such as the size of the ship, the length of sailing, the speed, and the fuel type. A large cruise ship can use up to 250 tons of fuel daily, equivalent to over 80,000 gallons of gas, with fuel costs ranging from $80,000 to $200,000 per day.
Many newer cruise ships are powered by liquefied natural gas (LNG), which offers several benefits over traditional diesel engines. LNG burns cleaner than diesel, resulting in reduced emissions and a smaller carbon footprint. LNG fuel provides environmental benefits by avoiding the fuel containment, spillage, and safety issues associated with diesel storage. LNG is also not flammable in its liquid state, unlike diesel.
The use of LNG can lower operational and capital expenses compared to traditional diesel generators. While LNG generators may have a lower power output, installing multiple generators in a parallel configuration can provide comparable or even greater power output with added flexibility and scalability. LNG technology enhancements have also led to cost savings, with LNG generators offering a lower total cost of ownership (TCO) than diesel generators.
The switch to LNG as a marine fuel has contributed to reducing global carbon dioxide (CO2) emissions. LNG produces significantly fewer nitrogen oxide (NOx) emissions, carbon monoxide (CO) emissions, and particulate matter compared to diesel fuel. For example, a heavy-duty truck running on LNG emits 99% less particulate matter and up to 15% less CO2 than a diesel engine.
Overall, LNG is a more environmentally friendly alternative to diesel, making it a preferred choice for enterprises seeking to operate in a more eco-friendly manner and be considered "green" companies.

Size matters: Bigger ships use more fuel
The cost of running a cruise ship is significant, and fuel is one of the highest expenses. The size of the ship plays a significant role in how much fuel it will use and, consequently, how much it will cost to refuel.
A larger cruise ship can typically hold around two million gallons of fuel, while smaller cruise ships might hold 100,000 to 130,000 gallons. A large ship, over 300 meters in size, might consume up to 250 tons of fuel per day, equivalent to over 80,000 gallons of fuel. This means a large ship can use up to $200,000 worth of fuel in a single day. In contrast, a smaller ship will use less fuel and cost less to refuel. For example, a cruise ship with 1,000 passengers and 700 crew members might spend about $15,000 a day on fuel, or $105,000 for a seven-day cruise.
The length of the sailing is another factor that affects fuel cost. The longer the sailing, the more fuel the ship will consume. Speed also plays a role, with faster speeds requiring more fuel due to the increased power needed to propel the ship forward.
The type of fuel used also impacts the cost. Many newer cruise ships use liquified natural gas (LNG), which burns cleaner than traditional diesel or gas-powered engines. However, LNG has a lower fuel density than diesel, and its cost has increased due to the Russia-Ukraine war.
The high fuel consumption of cruise ships has led to concerns about their environmental impact. While a direct comparison is challenging due to different fuel types and emissions, cruise ships are considered major polluters, with some estimates suggesting they use more fuel per day than the average person in their lifetime.

Speed: Faster cruising uses more fuel
The cost of running a cruise ship is significant, and one of the highest expenses is the fuel needed to power the ship. The cost of fuelling a cruise ship depends on several factors, including the cost of fuel, fuel type, size of the ship, length of sailing, and speed.
Speed is a crucial factor in the cost of fuelling a cruise ship. The faster a cruise ship sails, the more fuel it consumes due to the increased power required to propel the ship forward. This is why cruise ships typically maintain a leisurely pace throughout the voyage.
A large cruise ship can burn up to 250 tons of fuel per day, equivalent to over 80,000 gallons of fuel or gas. This means that a cruise ship with 1,000 passengers and 700 crew members could spend approximately $15,000 on fuel per day, resulting in a total fuel cost of $105,000 for a seven-day cruise.
The size of the ship also plays a significant role in fuel consumption. Larger ships require more fuel and have larger fuel tanks, with some of the biggest cruise ships capable of holding upwards of four million gallons of fuel. Smaller cruise ships, on the other hand, may hold around 100,000 to 130,000 gallons of fuel.
It is worth noting that modern cruise ships are increasingly adopting liquified natural gas (LNG) as a fuel source due to its environmental benefits and higher calorific value, which improves fuel efficiency. However, the recent increase in LNG fuel costs due to the Russia-Ukraine war has posed a challenge for ship operators.
