What is fuel gas supply system?

LNG-FGSS. The KONGSBERG LNG Fuel Gas Supply System (LNG-FGSS) is a complete system comprising of an LNG storage tank, LNG Process System, Bunker Station and Control& Safety System. The system is designed to supply gas in the range of 6-16 barg to dual fuel and pure gas engines.

What is an LNG system?

Heavy-duty liquefied natural gas (LNG) vehicles work much like gasoline-powered vehicles with a spark-ignited internal combustion engine. The natural gas is super-cooled and cryogenically stored in liquid form, usually in a tank on the side of the truck.

How does LNG bunkering work?

LNG Bunkering is the practice of providing liquefied natural gas fuel to a ship for its own consumption. The key advantage of LNG as a fuel is the vast reduction in pollutant caused by the more traditional method of fuelling ships such as heavy fuel oil, marine diesel fuel (MDO) and marine gas oil (MGO).

What is LNG dual fuel?

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.

Is natural gas and LNG the same?

LNG is natural gas that is cooled to -260° Fahrenheit, the temperature at which natural gas becomes a liquid. The volume of the liquid is 600 times smaller than the gaseous form. Some ships, trucks, and buses have specially designed LNG tanks to use LNG as fuel.

What is the difference between LNG and LPG?

LPG fuel, or liquefied petroleum gas, is a liquefied gas and is a byproduct derived while extracting crude petroleum. LPG weighs twice as much as air and is colorless, odorless and is a highly flammable explosive gas. LNG fuel, or liquefied natural gas, is a natural gas converted to liquid form through liquefaction.

How long does it take to load an LNG ship?

Usually, LNG carriers arrive at the loading terminal in such a cold condition and the actual cargo loading lasts for 20 hours. If the vessel arrives in warm condition, it must be cooled down first, which can extend the loading up to 30 hours.

What is bunkering in ship?

Bunkering (Marine Fuelling) In shipping, bunkering refers to the fuelling of ships with marine (bunker) fuels used to power them, and also includes food and drinking water supplies for the crew.

Is LNG better than diesel?

LNG is the cleanest-burning fuel available. LNG produces 20% less carbon dioxide (CO2) emissions than diesel and the combustion does not emit soot, dust or fumes.

Is LNG more expensive than natural gas?

According to data from the U.S. Department of Energy, CNG and LNG have had relatively similar or lower costs as compared to gasoline and diesel since 2000. LNG prices: Because LNG has a more involved production and transportation process, its prices are typically higher than CNG prices.

Is the LNG fuel system part of the propulsion system?

The LNG fuel system can be offered as a standalone product, as well as a part of a complete propulsion system. Wärtsilä can deliver LNG systems for propulsion and power generation for any applicable types of ship or engine. Type C pressure vessel. Design pressure 6-9 bar.

What is the Wartsila fuel gas supply system ( lngpac )?

Wärtsilä fuel gas supply system (LNGPac) is a complete fuel gas handling system for LNG ships and includes the bunkering station, LNG tank and related process equipment. Wärtsilä Online Region Wärtsilä GlobalGlobal contact information

Where is the LNG process equipment located on a ship?

LNG process equipment locatedinside built-on tank connection space or deck mounted vaporising skid. Class approved safety and control system. Remote actuated and manually operated cryogenic valves. Dedicated control and monitoring system.

What does Mitsubishi Shipbuilding do for LNG carriers?

Mitsubishi shipbuilding provides not only FGSS package, but also engineering services for designing and building LNG fuel ships based on the long experience and know-hows which have been accumlated by building LNG carriers. And after ship delivery, Mitsubishi shipbuilding supplies spare and/or repair parts and dispatchs service engineers.
