What You'll Learn
LNG fuel is cleaner than diesel
The Carnival Celebration cruise ship is powered by LNG fuel. LNG, or liquefied natural gas, is a fossil fuel like oil or coal, but it is the cleanest-burning fossil fuel available. LNG is also significantly cheaper than diesel.
LNG has been the safest fuel for the last 50 years. It is colorless, odorless, non-toxic, and non-corrosive. Its high ignition temperature of 1200 °F (compared to 599 °F for gasoline) and limited flammability range make its unintentional combustion highly unlikely. LNG is not flammable when in a liquid state, unlike diesel. It also has an excellent transport safety record, with over 80,000 LNG cargoes delivered over the last 50 years with no loss of cargo tank containment and no onboard fatalities attributable to LNG.
LNG is also much cleaner than diesel. LNG trucks produce just .2 NOx grams bhp/hour, compared to more than 8 grams bhp/hour for diesel trucks. LNG also produces 20% less carbon dioxide (CO2) emissions than diesel, and its combustion does not emit soot, dust, or fumes. LNG also generates almost no particulate matter or soot emissions, while diesel fuel does.
LNG is also more environmentally friendly than diesel in other ways. LNG does not have the fuel containment, spillage, and environmental concerns associated with storing diesel fuel. LNG is also non-polluting in the rare event of a spill, as it quickly dissipates upon contact with air and water.
Overall, LNG fuel is a much cleaner and safer alternative to diesel, and it is also more cost-effective.

LNG fuel has a lower density than diesel
The Carnival Celebration cruise ship is the second-newest and largest vessel in the Carnival Cruise Line fleet. It is among the world's largest cruise ships, accommodating 5,200 passengers and spanning 1,130 ft (344 m) in length. The Carnival Celebration is powered by LNG fuel, which stands for liquefied natural gas. LNG is predominantly methane (CH4) that has been cooled to a liquid form for safe storage and transport.
However, LNG fuel also has some disadvantages. LNG-powered ships require specialised equipment and training, and there is a risk of methane slip, where unburned methane escapes into the atmosphere. Nevertheless, LNG is still a popular choice for powering ships, as it is cost-effective and reduces greenhouse gas emissions and other harmful pollutants. LNG is also safer than conventional fuels, as it is odorless, colorless, non-toxic, and non-corrosive.
The Carnival Celebration is equipped with four Caterpillar Marine LNG engines, which generate a total output of 57.2 MW. The ship features three cryogenic steel LNG tanks with a total capacity of approximately 3,200 m³, which is sufficient for approximately 14 days of operation.
