  • How is LNG stored on ships in 2023?

    What is LNG?

    LNG, or Liquefied Natural Gasis a form of natural gas that undergoes a liquefaction process to facilitate its transportation and storage. This process involves reducing the temperature of natural gas to around -162°C (-260°F), converting it into a highly dense and volumetrically efficient liquid. how to recover a file in pages mac This transformation allows LNG to be transported in large quantities, expanding its reach and accessibility globally.

    LNG is widely recognized for its advantages as a clean and versatile energy source. When compared to other forms of energy, it has low emissions of carbon dioxide (CO2) and other pollutants, making it a more environmentally friendly alternative. In addition, LNG has a high energy density, which means that a smaller amount of LNG can provide a significant amount of energy compared to natu

    How is LNG stored?

    For the storage of LNG, especially during sea transport, specialized gas carriers are used and this is a complex process that involves the use of tanks specifically designed to withstand the extreme temperature and pressure conditions of liquid LNG. These tanks are constructed with highly efficient insulating materials such as stainless steel, nickel-aluminum or other special alloys to minimize heat transfer and keep the LNG in its liquid form.

    There are two main types of LNG tanks used on ships: membrane tanks and independent tanks.

    Membrane tanks are composed of an internal structure containing the LNG, surrounded by a thermal insulation layer and an external membrane. The membrane is made of low-temperature resistant materials such as metal-reinforced polyurethane or other high-strength materials. how to recover deleted files after swtiching to windows 10 These tanks are designed to withstand the pressure and temperature variations as well as the mechanical stresses caused by the ship’s movements. The thermal insulation layer around the frame and membrane helps to reduce heat transfer to the outside and keep the LNG at a cryogenic temperature.

    Independent tanks, on the other hand are thermally insulated cylindrical or spherical structures that directly store LNG. They are constructed with high-strength materials such as carbon steel or stainless steel that can withstand the low temperatures and pressures of natural gas and to prevent leaks and ensure its safety during transportation. They can be equipped with a containment system to capture any eventual leakage and prevent LNG from coming into contact with the ship’s hull.

    During storage, it is essential to constantly monitor the temperature and pressure of the tanks to ensure the safety and integrity of the LNG. Control and safety systems such as sensors, valves and alarm systems are installed to monitor and control the state of the storage tanks. In addition, ships carrying LNG are equipped with ventilation and pressure relief systems to prevent the build-up of flammable or hazardous gases. recover deleted files from network folder


    Storage of LNG on ships requires strict adherence to safety regulations and standards such as the International Liquefied Gas Code (IGC Code) and the International Code for Construction and Equipping of Ships Carrying Liquefied Gases in Bulk (IGF Code).

    These codes establish specific guidelines for the design, construction and operation of LNG storage tanks on ships, with the primary objective of ensuring the safety of ships, crews and the environment throughout the LNG storage and transport process.

    Compliance with these regulations is vital not only for the safety, but also for the sustainability of the offshore LNG industry. Efficient and safe storage of LNG on ships contributes to the reduction of greenhouse gas emissions in maritime transport, as well as to the reliable supply of energy worldwide. recover deleted files from usb thumb drive Therefore, the industry continues to invest in technological innovations and the improvement of safety and compliance practices, promoting an increasingly safe and sustainable LNG sector.
