※ This video is part of <Extreme Job - LNG Production Base and Salt Farm> broadcast on July 20, 2024. Natural gas and salt are essential to our lives. There are people who do their best to safely supply these two in the best condition. Liquefied Natural Gas, mainly used as city gas. And salt, which plays the most important role in adding flavor to food. Let's visit the hot site where these two natural raw materials are being worked on. - Everything about LNG, from LNG ships to production bases! Liquefied Natural Gas, more familiar to us as city gas. It is mainly fuel gas provided through pipelines to homes and factories in the city. Since it is a fuel that is imported in its entirety, safe transportation and storage are of the utmost importance. LNG is liquefied by cooling to -162℃, compressed to 1/600 of its volume, and then transported by ship. The scale is so large that four tugboats are needed to dock a 95,000-ton ship at a port. The towing work begins with tension as the fuel is loaded. After safely anchoring, the unloading work begins. The amount of LNG that needs to be unloaded is a whopping 130,000 KL (65,000 tons), and the situation is that they have to spend 24 hours a day just unloading. They have to check frequently to ensure safe unloading, so there is no time to rest. However, since it is work to deliver energy essential to life, the workers willingly work hard and sweat. Meanwhile, another LNG production base is under construction. Here, the roof-raising work (Roof Air Raising) of the LNG storage tank is in full swing. Roof-raising work refers to cutting-edge technology that raises the roof installed on the ground by about 45 meters using internal pressure. The LNG storage tank roof is 90 meters in diameter and weighs over 1,000 tons, so the usual method of work is dangerous. That's why this technology was used. Even while the roof is being built, confirmation and additional welding for accurate process are essential! If you make a mistake, the roof may collapse and you may have to start over from the beginning, so they are very careful. The best engineers are pouring all their efforts into building safe LNG storage tanks. Let's meet the people who are doing their best behind the scenes to ensure that LNG, a convenient fuel, can be used safely. ✔ Program name: Extreme Job - LNG production base and salt farm ✔ Broadcast date: 2024.07.20
