The Project
Thessaloniki FSRU, an Independent Natural Gas System licensed by RAEWW, is a major new project comprised of
• an offshore LNG terminal which includes two vessels, one FSRU (Floating Storage and Regasification Unit), one FSU (Floating Storage Unit) and a central platform located at 4,4 km offshore the subsea pipeline landing point, and
• a system of subsea (4,4 km) and land (7 km) pipelines and accompanying gas transport infrastructure up to Elpedison’s power generation facilities and the National Natural Gas Transmission System (NNGTS).
Thessaloniki FSRU, due to its strategic location, will contribute to the security of gas supply in the entire South-East European region, as well as to the management of congestions on the NNGTS, comprising a new flexible and secure natural gas entry point for Greece.
Key Components of the Terminal
Thessaloniki FSRU is designed to deliver natural gas to the NNGTS via a new entry point in northern Greece, west of Karperi-Komotini branch.
The Project consists of the following components:
• Two vessels (one FSRU and one FSU) that will be permanently moored at the selected location, and where LNG unloading, storage and regasification will take place
• Breasting and mooring facilities for the FSRU and FSU
• A platform to accommodate the necessary equipment for FSU-to-FSRU LNG transfer, connection to high-pressure subsea pipeline, etc.
• Offshore/onshore pipelines and metering facilities
Key project data
The siting of the LNG terminal and the routing of the offshore pipeline have been accurately chosen by accounting for the bathymetry of the area, as well as limitations imposed by existing anchorages and marine infrastructure and the marine traffic in the area.
The two vessels, one FSRU and one FSU, are designed to have a combined LNG storage capacity ranging between 250.000 m3 and 280.000 m3.
During ship-to-ship operations, LNG will be loaded by LNG carriers into the FSU through cryogenic hoses.
The regasification system is designed for a nominal send out capacity of 500 mmscf/day, i.e. approximately 150 GWh/day.
The pipeline design entails a 24-inch pipeline with an offshore and an onshore part:
• A 4.4 km offshore route, connecting the regasification system to the beach valve
• A 7 km onshore route, connecting the beach valve to the entry point into the NNGTS and serving ELPEDISON’s power generation facilities in Thessaloniki area
• Metering stations shall be installed at the interconnection between the onshore pipeline and the NNGTS and at the delivery points to ELPEDISON’s power plants
