To address the challenge of climate change, GTT is innovating to offer cutting-edge technologies <\/strong><\/span><\/p>\n

which enable\u00a0the maritime sector to reduce its impact as much as possible.<\/strong><\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Liquefied natural gas (LNG) is an essential transitional energy source for ship propulsion, reducing emissions and improving efficiency.<\/p>\n

As a responsible choice, until a more sustainable energy system and its supply chain are ready, LNG paves the way for carbon-free shipping.<\/p>\n

Since 2008, the International Maritime Organisation has launched measures to reduce pollutants, which are gradually coming into force on a global scale.<\/p>\n

    \n
  • reduce CO2<\/sub> emissions per transport activity, on average for all international shipping, by at least 40% by 2030 and by 70% by 2050 compared to 2008 ;<\/li>\n
  • reduce the total volume of annual GHG emissions by at least 50% by 2050, compared with 2008.<\/li>\n<\/ul>\n\n\t\t<\/div>\n\t<\/div>\n

    Using LNG as fuel immediately reduces a ship’s overall emissions. By recovering the little LNG that evaporates and improving the efficiency of ships, we are offering a compliant and competitve solution.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

    From container vessels and cruise ships, to tankers and bulkers, LNG is an alternative fuel solution suited to all kind of ships. This solution is flexible, even throughout the vessel\u2019s lifespan with conversion systems.<\/p>\n

    Membrane tank volumes can vary from 1,000 m3<\/sup>\u00a0for passenger ships, to 10,000 m3<\/sup>\u00a0for tankers, and close to 20 000 m3<\/sup>\u00a0for very large container vessels.<\/p>\n

    GTT is also offering solutions for all applications of the LNG supply chain :<\/p>\n

      \n
    • Bunker barges and vessels used to bunker ships in every kind of navigational areas (inland waters, coastal, seagoing, shallow draft, etc.);<\/li>\n
    • Small and medium-capacity LNG carriers used as refueling vessels (used for LNG ship-to-ship transfers) and suitable for inland waterways and coastal zones;<\/li>\n<\/ul>\n\n\t\t<\/div>\n\t<\/div>\n
