    Public Expenditure

    • 6.4 m€ (PA2014-2020)

    Fund
    European Regional Development Fund (ERDF)

    Project description

    In order for DESFA to manage with the best possible way the produced boil-off gases (BOG) in the LNG Terminal of Revithoussa from the cryogenic facilities (2nd upgrade) as well as from the unloading/ loading phase and mainly to avoid the combustion of the gases in the flair of the facility in the case of no send-out operation, DESFA will install a new compressor station for BOG so as to increase the pressure and inject them to the national natural gas system.

    Benefits

    • Enhance Efficiency of NNGS and effective operation
    • Decrease LNG losses – energy saving
    • Environmental benefit by eliminating the carbon dioxide emissions during the period of non- operation of the Terminal.

  • New jetty for small-scale LNG in Revithoussa

    Project description

    The project will be an implementation of the ongoing studies under POSEIDON MED II.

    POSEIDON MED II, under the auspices of the INEA (Innovation and Network Executive Agency), is part of the necessary steps towards adopting liquefied natural gas as a marine fuel in the Eastern Mediterranean.

    The new jetty is planned to be constructed in the northeastern part of Revithoussa and will serve the operation of the loading to small ships (1.000 m3 and up to 20.000 m3). The smallest of them will supply boats (cruisers, containerships, Ro-Pax), to the port of Piraeus. The larger ones will supply satellite LNG storage and distribution stations to other ports in Greece or abroad or will operate virtual pipelines to islands.

    The project includes:

    • Construction of a new port facility for the loading of ships with a capacity of 1.000 m3 - 28.000 m3.

    • Electromechanical equipment and LNG loading arms

    Benefits

    • Supply of new areas with gas
    • Substitution of oil with LNG in marine transport

  • Upgrade of the supervision Control and Data Acquisition System (SCADA) for the main and backup dispatching Centers (Phase B)

    Operational Programme

    • Competitiveness, Entrepreneurship 2007-2013 & Competitiveness, Entrepreneurship and Innovation PA 2014-2020
