LNG ships are designed to transport liquefied natural gas (LNG). LNG is a gas at ambient temperature and pressure, but it can be liquefied by cooling it to -162 degrees Celsius. LNG ships must be designed to withstand the very low temperatures required to keep the LNG in liquid form.
LNG ships typically have a double hull and a double insulation system. The tanks that store the LNG are also made of special materials that can withstand the low temperatures.
LNG ships have a variety of safety features, including pressure relief valves, flame arrestors, and inert gas systems. These features help to prevent accidents and fires.
