打破韓國壟斷！中國突然造出最大LNG船，建造難度超過航空母艦
2018-11-28 由 米爾軍事 發表于軍事
近日，上海滬東中華造船集團傳來好消息，國產第一艘17.2萬立方米雙艉鰭推進零貨損型LNG船研製成功，這艘巨船也是全世界範圍第一艘在17萬立方級別當中採用雙低速機直推的LNG船，它的甲板面積相當於30個籃球場，一次性運輸的天然氣足夠供給2300萬人口的上海1個月的天然氣需求。
說到LNG船，可能不少人都會表示比較陌生，那麼這玩意究竟是用來幹什麼的呢?說白了，它就是個液化天然氣的專用運輸船，LNG船就像是一輛在海上漂泊的超級冷凍車一樣，為了儘可能運輸到更多數量的天然氣，人類把天然氣溫度降低到零下163攝氏度，因為在這個溫度，天然氣會被壓縮600倍成為液化天然氣，從而更加便於運輸。
縱觀全球，具有建造LNG船資質的船廠，總共加起來也不過13家而已，啥?因為LNG船很有可能是製造難度最高的民用船隻，甚至相當程度之上超過了軍用航空母艦，是全球公認的高技術，高可靠性，高附加值的「三高」船隻，因而LNG船就像航空領域的發動機一樣，常常被尊稱為世界造船界皇冠上的明珠，宏大並且精細絕倫，是製造業水準閾值的直觀體現。
LNG船的建造難點在於其核心部位：液貨艙，液貨艙需要有一種叫做殷瓦鋼的特殊合金，它具有導熱係數低，膨脹係數小，塑性以及韌性高等優點，十分適合貯存零下163攝氏度的液態天然氣。
然而，它的加工難度是相當高的，這主要體現在焊接程序上面，大多數殷瓦鋼的厚度只有0.7毫米，而一艘LNG船的殷瓦鋼焊縫至少需要長達130公里，在這漫長的焊接點之中，但凡存在哪怕一丁點焊接問題，都會導致整大塊殷瓦鋼板的損失，動輒返工1000小時，焊接難度之大，難以想像，所以起初我國掌握這種焊接技術的工人，全國上下不過16個而已。
就像公路上行駛的油罐車一樣，LNG船在海上也是令人退避三舍的存在，而即使達到了目的地，出於保障碼頭人員以及財產安全的考量，也不會令其輕易靠岸，這主要還是因為LNG船的特殊性質所導致的結果。
LNG船罐體內外壓強通常可以高達幾十個大氣壓，因而焊接工作稍有遺漏，哪怕是針尖大小的氣孔，都會直接導致LNG船變成一顆原子彈，滿載狀態下的LNG船所能夠攜帶的壓縮液態天然氣一旦發生爆燃，威力不亞於60顆原子彈，所以說，能否把LNG船造好，真心是體現了一個國家造船水平如何。
作為近年來船運市場的熱潮，根據海運對未來預期的評估，LNG船最高日租金將達到20萬美元，所以各國都想在這裏分一杯羹，可惜LNG船不是你想造，想造就能造。目前，我國LNG船的製造水準已經超過了日本，並在去年接連拿下了四個來自日本的大訂單，總價值超過50億人民幣，當然，我們也需要清楚地認識到，在LNG船領域，韓國造船業仍然佔據着這個市場的大頭。
今年，在全球範圍之內，總共達成了33艘LNG船訂單，但這當中中國只拿到了2單，其餘幾乎全部都被韓國的大宇，現代，三星等三大造船巨頭所包攬，憑藉着豐富的經驗，韓國這幾家企業慣用壓低價格的老套路，將價格普遍壓到了1.85億美元，搶到了大多數訂單。
不過我們也不必氣餒，韓國造船企業之所以大幅度壓低價格正是出於對我國LNG船乃至整個造船業興起的擔憂，韓國的LNG船圍爐系統存在可靠性不足的缺陷，上個月才發生過三星重工LNG船圍護系統「漏氣」結冰返廠維修的糗事，如此下去，他們招牌只會越做越爛。

Break the Korean monopoly! China suddenly created the largest LNG ship, which is more difficult to build than an aircraft carrier.
2018-11-28 published by the Mil Military in the military
Recently, Shanghai Hudong Zhonghua Shipbuilding Group has received good news. The first domestically produced 172,000 cubic meters double stilb thrust zero-loss LNG ship was successfully developed. This ship is also the world's first ship to adopt in the 170,000 cubic class. The double-low-speed machine directly pushes the LNG ship, which has a deck area equivalent to 30 basketball courts. The one-time transportation of natural gas is enough to supply Shanghai with a population of 23 million people for one month of natural gas demand.
Speaking of LNG ships, many people may say that they are relatively strange, then what is this thing for? What is it, it is a special transport ship for LNG, LNG ship is like a super drift at sea. Like a refrigerated truck, in order to transport as much natural gas as possible, humans have lowered the temperature of natural gas to minus 163 degrees Celsius, because at this temperature, natural gas is compressed 600 times into liquefied natural gas, making it easier to transport.
Throughout the world, the number of shipyards with the qualification to build LNG ships is only a total of 13 or so. Why? Because LNG ships are likely to be the most difficult civil vessels to manufacture, and even more than military aircraft carriers, it is recognized globally. The high-tech, high-reliability, high-value-added "three high" vessels, so LNG ships are like the engines of the aviation industry, often called the crown jewel of the world shipbuilding industry, grand and fine, is the manufacturing level An intuitive representation of the threshold.
The difficulty in the construction of the LNG ship lies in its core part: the cargo tank. The cargo tank needs a special alloy called Yinwa Steel. It has the advantages of low thermal conductivity, small expansion coefficient, high plasticity and toughness, and is very suitable for storing liquids at minus 163 degrees Celsius. natural gas.
However, its processing difficulty is quite high, which is mainly reflected in the welding procedure. Most Invar steel is only 0.7 mm thick, and the Yinwa steel weld of an LNG ship needs at least 130 km. Among the long welding points, however, even if there is even a little bit of welding problem, it will lead to the loss of the entire large piece of Yinwa steel plate. It will be reworked for 1,000 hours. It is difficult to imagine the welding. Therefore, at the beginning, the workers who mastered this welding technology in China, There are only 16 in the country.
Like a tanker driving on a highway, an LNG ship is also a retreat at sea, and even if it reaches its destination, it will not be easy to dock for the protection of dock personnel and property safety. Mainly due to the special nature of LNG ships.
The pressure inside and outside the LNG tank can usually be as high as several tens of atmospheres, so the welding work is slightly missing. Even the pores of the needle tip will directly lead to the LNG ship becoming an atomic bomb. The compressed liquid can be carried by the LNG ship under full load. Once the natural gas deflagrates, the power is no less than 60 atomic bombs. Therefore, whether the LNG ship can be built is really a reflection of the level of a country's shipbuilding.
As a boom in the shipping market in recent years, according to the assessment of the future expectation of shipping, the maximum daily rent of LNG ships will reach 200,000 US dollars, so all countries want to share a piece of it here. Unfortunately, LNG ships are not what you want to make. . At present, the manufacturing level of China's LNG ships has surpassed that of Japan, and last year won four large orders from Japan, with a total value of more than 5 billion yuan. Of course, we also need to clearly understand that in the field of LNG ships, The Korean shipbuilding industry still occupies the bulk of this market.
This year, a total of 33 LNG ship orders have been reached on a global scale, but China has only received 2 orders, and almost all of them have been taken over by Daewoo, Hyundai, Samsung and other three major shipbuilding giants. The experience of these companies in South Korea is accustomed to the low price of the old routine, the price is generally pressed to 185 million US dollars, grabbed most orders.
However, we do not have to be discouraged. The reason why Korean shipbuilding companies have drastically lowered the price is precisely because of the concern about the rise of China's LNG ship and even the entire shipbuilding industry. South Korea's LNG ship's surrounding furnace system has defects of insufficient reliability, which occurred only last month. After the Samsung Heavy Industry LNG ship enclosure system "leakage" icing back to the factory to repair the anecdote, and so on, their signboard will only get worse and worse.

If completed, the new ship will eclipse the biggest LNG transportation vessel in the world – Qatar’s ‘Mozah’ vessel. The tanker, built in 2007, is almost the size of four football fields (345 meters long and 53.8 meters wide) and can carry up to 266,000 cubic meters of LNG.
