LNG Technology

Natural gas is growing in importance as an energy source around the world. In order to facilitate its transportation and storage, it is pressurized into Compressed Natural Gas (CNG) or converted into Liquid Natural Gas (LNG). By cooling it to approximately -160°C (-260°F), the volume of natural gas can be reduced to about 1/614th at atmospheric pressure.

Natural gas is transported in specially designed cryogenic vessels and stored in specially designed tanks. The special pumps that charge and discharge carrier vessels with LNG typically feature an integral shaft with the entire motor, bearings and all other components completely submerged and flooded with LNG. These submerged pumps can be safely supplied with electricity by using our power and instrumentation penetrations for LNG vessels.
