This solution consists of a vessel, new or reconverted from a carrier, equipped with tanks for LNG storage and with all the required vaporization process equipment.
In the FSRU the LNG delivered by LNG carriers is received by the FSRU offloading system, stored in tanks, pumped, regasified into natural gas and delivered to consumers through a flexible or rigid riser, connected to the subsea pipeline or via high-pressure loading arms fixed on a jetty. Prior to its delivery, the natural gas flow rate is measured by an ultrasonic flow meter and the gas is odorized.
LNG is not explosive in its liquid state. LNG vapours (its natural gas form) are only flammable within a limited range of concentration in the air and require a number of factors to occur such as a closed space, ignition source and proper ratio of natural gas to air. If the concentration of natural gas in the air is lower than 5%, it cannot burn because of insufficient fuel.
Natural gas is used extensively in residential, commercial, industrial and power generation applications:
- The electric power generation sector uses natural gas to produce clean electricity.
- The industrial sector uses natural gas as a source of process heat, as a fuel for the generation of steam and as a feedstock in the production of petrochemicals and fertilizers.
- Natural gas is also used directly by residential and commercial users as a source of home heating, water heating, clothes drying, and in cooking applications.
- Natural Gas is also seeing increased use in the marine, rail and road transportation sectors as it provides many cost saving and environmental benefits
