According to Gastrade S.A., the project sponsor, the pipeline will run from the Alexandroupolis LNG Terminal subsea at a depth of 15 meters for 24 kilometers and then onshore for another 4 km. It will connect to the NNGS (ESFA) at the new Metering / Regulating Station near the village of Amfitriti. Gastrade says "the Alexandroupolis INGS will have the ability to directly connect with other pipelines which are planned to be developed in the area in the future, such as the Trans-Adriatic Gas Pipeline."[5]

Alexandroupolis INGS Terminal Pipeline is one of the European Commission's Fourth 'Projects of Common Interest' (PCI). According to the European Commission, the 6.9.1 PCI consists of: 1) the Alexandroupolis LNG Terminal 2) "The gas transmission pipeline will have a total length of 28 km (4 km onshore and 24 km subsea), a send out capacity of 15.1 mcm/d, DN30” and a design pressure of up to 110 bar. The pipeline will be connected to the NNGTS through a Metering and Regulating Station, which will be constructed and operated by DESFA, the NNGS TSO." 3) A Metering and Regulating Station and 4) A Compressor station at Kipi.[7]

Construction on the project started in the first quarter of 2022, along with the Alexandroupolis LNG terminal. Although initially expected to be commissioned in 2022, Gastrade expects the pipeline and all associated infrastructure to come online in early 2023.[8]

In August 2023, Saipem announced that its pipelay vessel Castoro 10 had completed construction of the 24-kilometre-long offshore section of the pipeline.[9]
