Definitions
- TITLE Process for the production of electricity by means of an installation intended to be placed in a body of water
- the present invention relates to a method of producing electricity by means of an installation intended to be placed in a body of water.
- the facility is suitable for receiving liquefied natural gas (usually designated by the acronym "LNG”) and for producing electrical energy from this liquefied natural gas, once it has been regasified.
- LNG liquefied natural gas
- This natural gas is produced from a reservoir located under a body of water, or on land, then liquefied and conveyed to the facility.
- a liquefied natural gas reception terminal is installed at a reception jetty.
- LNG carriers deliver the liquefied natural gas which is stored in storage tanks and then regasified. Part of the gas produced is then used by a gas-fired power plant to produce electricity distributed on the electricity network.
- FSRU floating storage and regasification Unit
- LNG carrier liquefied natural gas
- the liquefied natural gas is then temporarily stored on the FSRU and then returned to gaseous form before being sent to an onshore gas-fired power plant.
- the gas produced by the FSRU is sent to a floating barge receiving the gas and then producing electrical energy.
- a solution allows flexibility and mobility of electricity production compared to an onshore power plant.
- Such a solution makes it possible to electrify an area quickly and with a reduced investment.
- FSRUs are new ships or second-hand LNG carriers converted into FSRUs.
- the cost of FSRUs represents a very significant portion of the cost of such power generation projects. For example, the cost of a newly built FSRU often exceeds 200 million euros. As for the use of second-hand LNG carriers, it enables some savings to be made, but the cost of the conversion work to FSRU is still around 100 million euros because significant modifications to the LNG carriers are necessary.
- FSRP for “Floating Storage Regasification and Power generation barge”.
