The Project

The bow of the Alexandroupolis INGS Floating Unit

The Alexandroupolis Independent Natural Gas System (INGS) project is a modern, cutting edge technology project which comprises an offshore floating unit for the reception, storage and re-gasification of LNG and a system of a subsea and an onshore gas transmission pipeline through which the natural gas is shipped into the Greek National Natural Gas System (NNGS) and onwards to the final consumers. 

The Alexandroupolis INGS has also the capacity to connect with and transmit gas into other gas transmission systems which are planned in the same geographical region such as TAP (Trans Adriatic Pipeline). 

The Liquefied Natural Gas (LNG) will reach the INGS floating unit by means of LNG carriers, will be transferred into the floating unit through the unit’s loading arms and will be temporary stored in its cryogenic tanks.

Next,the LNG will be gasified at the regasification units and will be moved to the subsea pipeline via a submerged turret and a set of flexible risers. The 24 km subsea pipeline will cross the shore near the Apalos village area, east of the town of Alexandroupolis. The pipeline, onshore for the remaining section, will continue its northern route for another 4 km till it reaches the new Metering and Regulating Station, in the neighborhood of the village of Amphitriti where it will be connected to the NNGS.                                     

The floating Unit will be permanently anchored at a fixed location at a distance of 17.6 km SW from the port of Alexandroupolis and 10 km from the nearest opposite shore of Makri village. The swivel at the mooring turret will allow the floating unit to rotate by 360° in line with the direction of the sea currents and waves.

The Alexandroupolis INGS will create a fourth natural gas import gate into Greece, with a send-out capacity of 700,000 cubic meters of natural gas per hour or 6.1 billion cubic meters of natural gas per year and a storage capacity of up to 170,000 cubic meters of LNG.

Alexandroupolis INGS will secure new natural gas quantities for the supply of the Greek and the regional SE European markets, offering new sources and routes of natural gas supply, promoting competition to the benefit of the end consumers, enhancing the security of supply in Greece and the Balkan markets, improving the reliability and flexibility of the Greek National Natural Gas Transmission System and of the regional and trans-European gas networks and contributing to the achievement of the environmental targets of Greece. 

Commercial operations of Alexandroupolis INGS are expected to commence in 2023.

The implementation of the ''Alexandroupolis Independent Natural Gas System (INGS)" project has been included in the Operational Program of the NSRF "Competitiveness, Entrepreneurship and Innovation 2014-2020" (EPANEK), according to the decision of the Special Secretariat of the European Regional Development Fund issued on 22.09.2021.
