Did you know that there is a ship that carries cargo at minus 163 degrees? It is an LNG ship, a carrier that carries LNG (Liquefied Natural Gas), which is natural gas liquefied. Because of the characteristics of ships that must carry ultra-low temperature liquids, cutting-edge science and engineering technology are required. We will learn about the process of completing a giant LNG ship, the pride of the Republic of Korea, the core technology of each part, and the manufacturing principles of LNG ships. 1. Natural gas closely related to our lives What does an LNG ship have to do with our lives? You are saying that without knowing much! The gas stove fire that we use when cooking in the kitchen is also made of natural gas. Natural gas transported by LNG ships is transported and used from LNG storage facilities through pipes to homes across the country. In addition, natural gas is used as fuel in public transportation, buses that we use every day. Even now, natural gas is easily accessible at home, at work, and on the road, but the demand for natural gas is expected to increase explosively in the future. 2. The country that rules the sea, South Korea The world's No. 1 shipbuilding powerhouse, South Korea. South Korean shipyards occupy 1st to 6th places in the 'World's Top 10 Shipyards' (Clarkson, a shipbuilding and shipping analysis agency). (1st Hyundai Heavy Industries, 2nd Samsung Heavy Industries, 3rd Daewoo Shipbuilding & Marine Engineering, 4th Hyundai Mipo Dockyard, 5th STX Shipbuilding, 6th Hyundai Samho Heavy Industries) In particular, technology-intensive LNG ships are high value-added ships with a price of over 250 billion won per ship, and are called the flower of ships. It is even said that the country that builds LNG ships rules the sea. 3. Why is LNG attracting attention? As fossil fuel depletion approaches, interest in alternative energy is increasing. Natural gas, which is highly energy-efficient, is lighter than air and emits less air pollutants when burned, making it environmentally friendly. Due to these facts, natural gas is rapidly emerging as a next-generation energy source. Natural gas becomes liquid when it cools below -162 degrees Celsius, and its volume is reduced to 1/600, allowing it to transport more at once. 4. What is an LNG carrier? Natural gas is usually transported through pipes, but in countries like ours that are far from base stations, LNG (liquefied natural gas) is transported by ship. In the sea, where many dangers lurk, the cargo hold of a ship carrying LNG must withstand the extremely low temperature of -163 degrees Celsius and safely transport it to the LNG storage facility. That is why LNG carriers are manufactured using special techniques, unlike other ships. Although Korea is the world's No. 1 in LNG carrier construction technology, it is paying royalties for the LNG tank technology, which is the core of LNG carriers, using foreign technology. However, LNG carrier tanks are being developed in Korea recently. By developing not only Korean-style LNG tanks but also other parts of LNG carrier technology, Korea is truly beginning to emerge as the world's strongest shipbuilding country. Let's take a look at the steps that the world's No. 1 shipbuilding company, Korea, is taking to go further and higher. ✔ Program name: EBS Documentary Prime - Wonderful Science <Launching the cutting edge, LNG ship> ✔ Broadcast date: 2008.04.17 #TVGollaDunDocumentary #GollaDunDocumentary #Documentary #DocumentaryPrime #Shipbuilding #LNG #NaturalGas #Plant #MarinePlant
