What is TFDE?
TFDE stands for Tri-Fuel diesel electric propulsion ships specifically for LNG carriers.
What is tri-fuel engine?
Tri-fuel. A relatively recent technology development, a tri-fuel vehicle combines a ‘flex-fuel’ vehicle and a natural gas vehicle. A flex-fuel vehicle uses gasoline and ethanol, either exclusively or blended together. Thus a tri-fuel vehicle can operate on gasoline, ethanol (or both) or natural gas.
What is Xdf propulsion?
Dual-fuel engines, using gas admitted at low pressure and ignited by a low volume of liquid pilot fuel was a breakthrough in the marine industry. The X-DF engines offer new marine standards with low-pressure gas technology.
What is a dual fuel ship engine?
Dual-fuel engine is the diesel engine that can run on both gaseous and liquid fuels. The DF technology enables the engine to be operated on either natural gas, light fuel oil or HFO. Switching between fuels can take place seamlessly during operation, without loss of power or speed.
How does LNG ship engine work?
A marine LNG engine is a dual fuel engine that uses natural gas and bunker fuel to convert chemical energy in to mechanical energy. The natural gas is stored in liquid state (LNG) and the boil-off gas is routed to and burned in dual fuel engines.
How do diesel electric ships work?
In diesel-electric systems, multiple diesel engines, each driving an electric generator, produce the electric power that energizes the electric motors connected to the propellers as well as other electrical loads on the ship. Depending on electrical demand, not all diesel generators have to be operating at all times.
How do CNG engines work?
The CNG fuel system releases high-pressure gas from the fuel tank and transfers it through the fuel lines. The pressure regulator reduces the pressure, which is compatible with the engine fuel injection system. The spark plug ignites the compressed gas and starts the engine.

Why marine engines have 2stroke?
Why 2-stroke Engines are Used More commonly than 4-stroke on Ships? Fuel Selection: The fuel prices have gone sky high and better grade fuel is adding higher costs to vessel operation. A two-stroke engine can burn low-grade fuel oil and hence reduce the running cost of the ship.
Who builds LNG?
New building Of the global fleet, historically, about two-thirds of the ships have been built by South Koreans, 22% by Japanese, 7% by Chinese, and the rest built by a combination of France, Spain, and the United States.
Is LNG better than diesel?
The benefits of using liquefied natural gas (LNG) versus diesel for fuel are also clear: Natural gas burns significantly cleaner; produces lower emissions of sulfur, nitrogen and carbon dioxide into the atmosphere; and lacks the strong, distinguishing diesel odor.
What is the importance of diesel-electric propulsion?
The power plants are located in two separate engine rooms. A BP Shipping statement explained: “Diesel-electric propulsion was chosen because it significantly increases reliability and reduces air emissions and maintenance downtime.”
What is a vessel in medical terms?
Medical Definition of vessel : a tube or canal (as an artery, vein, or lymphatic) in which a body fluid (as blood or lymph) is contained and conveyed or circulated
What is a vessel in the Bible?
Definition of vessel 1a : a container (such as a cask, bottle, kettle, cup, or bowl) for holding something b : a person into whom some quality (such as grace) is infused a child of light, a true vessel of the Lord— H. J. Laski 3a : a tube or canal (such as an artery) in which a body fluid is contained and conveyed or circulated
What is a vessel for kids?
Kids Definition of vessel. 1 : a craft larger than a rowboat for navigation of the water. 2 : a hollow utensil (as a cup or bowl) for holding something.
