視頻解說(shuō)詞

我們所居住的地球，每天有上億輛汽車排放出尾氣污染，上百萬(wàn)艘船舶排放出廢氣污染，汽油、柴油燃燒的排放物正嚴(yán)重污染著我們的家園。
On the planet we live in, there are hundreds of millions of automobiles and millions of ships, which all emit emissions every day, firing gasoline and diesel into our atmosphere. 
經(jīng)過(guò)世界各國(guó)多年的探索和實(shí)踐，LNG被認(rèn)為是減輕環(huán)境污染最理想的替代燃料。
After years of exploration by many countries, LNG is considered to be the most ideal transportation fuel alternative available, with minimal atmospheric pollution potential.
LNG是液化天然氣的簡(jiǎn)稱。這種新型燃料，不但能夠大幅減少污染物排放，而且具有高度的安全性，與汽油、柴油和LPG相比，LNG的燃點(diǎn)更高，更加難以點(diǎn)燃，爆炸濃度下限更高，導(dǎo)致爆炸的幾率更低，同時(shí)，良好的揮發(fā)性使其難以聚集。具體來(lái)說(shuō)，LNG的安全性體現(xiàn)在以下幾個(gè)方面：
LNG is short for liquefied natural gas. This new fuel could not only reduce pollutant emission to a large extent, but also enjoys high level of safety. Proven to be a safer fuel than gasoline, diesel or LPG, LNG has a higher ignition point, making it less flammable. In addition, LNG has a higher cap requirement for any time of eruptions, greatly lessening the probability of explosion. Its inherent volatility causes it to evaporate quickly, preventing a concentrated gathering of gases, and also reducing the likelihood of an explosion. Concretely speaking, LNG is safe in following specific respects:
安全因素一 LNG本身具有安全的物理性質(zhì)
Safety Factor 1: A New Type of Naturally Safe Fuel
LNG必須在非常低的溫度下保存，一旦泄漏到空氣中，它會(huì)迅速氣化飄散，不會(huì)造成燃料聚集。
First of all, LNG is stored at a very low temperature. Once it is exposed to the environment, it will readily evaporate into the air, minimizing any danger of a fuel “cloud”.
把LNG加入水中，LNG蒸發(fā)后，水依然可以安全飲用。這就意味著，即使LNG發(fā)生泄漏，也不需要任何清理，它能迅速蒸發(fā)，不會(huì)有任何殘留污染。
When LNG is put into a cup of plain water, the water would be safe to drink due to the fast vaporization of LNG. That means that even in the case of spillage, cleaning up after LNG is not required.
LNG是一種溫度很低的液體，不容易被直接點(diǎn)燃，甚至可以熄滅點(diǎn)燃的香煙。
LNG is a low temperature liquid which is intrinsically difficult to ignite. It can even extinguish a burning cigarette.
安全因素二 LNG在車輛、船舶使用的各個(gè)環(huán)節(jié)是安全可靠的。
Safety Factor 2: LNG is both a safe and reliable fuel source when it is used to power vehicles and vessels
LNG汽車不但在操控與性能方面與傳統(tǒng)汽柴油車輛幾乎沒(méi)有差別，而且還能節(jié)省百分之十五到二十的燃料費(fèi)用。因此，從2008年開(kāi)始，我國(guó)的LNG汽車數(shù)量呈現(xiàn)爆發(fā)式的增長(zhǎng)，目前全國(guó)已有近7萬(wàn)輛LNG大巴和重卡投入使用。
LNG-powered cars have almost no difference in operation and functions in comparison with traditional gasoline or diesel cars; they could even save 15%-20% of fuel cost. Therefore, the number of LNG-powered cars has experienced a shocking increase from 2008, and now it has reached about 70,000 LNG buses and heavy trucks put in use.
LNG車輛如發(fā)生碰撞、翻車等交通事故，會(huì)不會(huì)導(dǎo)致LNG氣瓶破裂造成額外的危險(xiǎn)呢？在試驗(yàn)中，我們將LNG氣瓶從10米高處跌落，氣瓶受到相當(dāng)于兩車以50公里的相對(duì)時(shí)速碰撞產(chǎn)生的沖擊力。試驗(yàn)結(jié)果表明，氣瓶?jī)H僅發(fā)生了輕微的外部變形，沒(méi)有任何燃料泄漏。
如果車輛發(fā)生火災(zāi)事故，LNG氣瓶受到高溫灼燒后會(huì)不會(huì)有危險(xiǎn)呢？在試驗(yàn)中，我們將LNG氣瓶置于火焰上方進(jìn)行長(zhǎng)時(shí)間灼燒，由于受到保冷層的保護(hù)，外界的高溫很難傳遞到內(nèi)部，瓶?jī)?nèi)燃料依然保持低溫。由此說(shuō)明，即使發(fā)生火災(zāi)，LNG氣瓶也不易發(fā)生燃料泄漏的危險(xiǎn)。在一些其他原因?qū)е碌幕馂?zāi)事故中，雖然LNG汽車完全燒毀，但LNG氣瓶完好無(wú)損。
Will the LNG cylinder breakage in an auto accident or overturned bring forth extra danger?
In an experiment, we dropped an LNG cylinder from a height of 10m, by which it faces an impact of car crash in a speed of 50km/h. The result: not only did the cylinder remain intact and virtually leak-proof, but there was no frost or dew on the shell. If an automobile accident were to cause a fire, will LNG cause any danger? We then tested the safety of the LNG cylinder in a fire accident scenario.  We placed an LNG cylinder above a high-temperature flame for a long period of time, and the liquid contents had not been inordinately gasified, indicating the qualitative insulation of the LNG cylinder. This experiment also showed us that when a fire occurs, there is no risk of a fuel leak erupting from an LNG cylinder. If an automobile accident were to cause a fire, it would be due to some other unrelated reason.  In such cases the cars burned down completely, but the LNG cylinders were amazingly still perfectly sound without any sign of fuel leakage.
 
LNG作為船舶燃料使用也同樣安全，因?yàn)榇�用LNG儲(chǔ)罐的各項(xiàng)安全指數(shù)比車用氣瓶更高，同時(shí)還要能夠承受船舶運(yùn)動(dòng)和液體晃動(dòng)產(chǎn)生的沖擊力。
LNG is also safe as vessel fuels, since the safety standards of vessel LNG are higher than car LNG. The vessel LNG has to withstand the added pressure imposed by the shaking LNG. 
 
如果發(fā)生船舶碰撞事故，LNG儲(chǔ)罐可能受到擠壓，通過(guò)試驗(yàn)，我們模擬了兩艘300噸級(jí)船舶的碰撞，儲(chǔ)罐在擠壓下沒(méi)有破裂，僅發(fā)生輕微外部變形，局部固定失效。結(jié)果表明，船頭撞擊不足以對(duì)LNG儲(chǔ)罐造成穿透破壞，不會(huì)發(fā)生LNG燃料泄漏。
In cases of collision-type traffic accident, the LNG storage tank may face strong pressure and squeeze. We conducted an experiment, simulating the tragic collision of two 300-ton vessels. With a hydraulic metal bow, we enacted an extrusion and collision accident. We discovered that the outside layer of the tank was just slightly distorted, but not broken. Thus according to our experiment, there is no actual risk of an LNG leak even under these highly unlikely circumstances.
海洋中航行的船舶會(huì)受到鹽霧腐蝕的影響，為此我們通過(guò)試驗(yàn)?zāi)�擬了儲(chǔ)罐材料在海洋環(huán)境中暴露10年的后果。結(jié)果表明，適當(dāng)?shù)耐繉幽軌虮Ｗo(hù)儲(chǔ)罐不受腐蝕。
Vessels and ships on sails may be influenced by marine corrosion. To research this matter further, we simulated a marine environmental, 10-year corrosion experiment. The result showed that the appropriate anticorrosive surface coat can protect tank materials from corrosion.
除了LNG儲(chǔ)罐的安全保障外，LNG車、船內(nèi)部還配備了嚴(yán)格的安保系統(tǒng)，以LNG燃料船為例，所有可能發(fā)生泄漏的區(qū)域都設(shè)有可燃?xì)怏w探測(cè)器，即使微小的燃料泄漏也能及時(shí)發(fā)現(xiàn)，并開(kāi)啟聲、光報(bào)警，切斷閥門，阻止燃料進(jìn)一步泄漏。我們通過(guò)試驗(yàn)，驗(yàn)證了監(jiān)控系統(tǒng)能夠有效的實(shí)現(xiàn)這一功能。
Besides providing a safety guarantee on LNG storage equipment, safety control systems have been carefully installed within vehicles and vessels carrying, equipping with the flammable gas at every checkpoint where LNG could potentially leak. Even a minor fuel leak would be immediately detected. Once a leak is found, sound and light alarms will be activated immediately, and the fuel supply valve is cut off immediately to prevent any additional fuel seepage. We have found the safety control system can effectively perform this function.
 
同時(shí)，船上的所有艙室都配有通風(fēng)系統(tǒng)，保證可燃?xì)怏w不在室內(nèi)聚集，從而避免窒息爆炸的危險(xiǎn)。
A ventilation system has also been installed on every cabin in the vessel. This eliminates the risk of either suffocation or explosion due to gas accumulation. 
另外，在安全等級(jí)較高的區(qū)域還配有火災(zāi)探測(cè)器，以及時(shí)發(fā)現(xiàn)火情并報(bào)警。
Smoke sensors have been installed in a high safety control areas to detect a fire at the earliest opportunity and sound the warning alarm.
 
安全因素三 嚴(yán)重事故中LNG的危害是有限且可控的
Safety factor 3: Controllable Damage by LNG in Hazard Accidents
 
盡管LNG本身和使用環(huán)節(jié)都已證明足夠安全，我們?nèi)匀粚?duì)一些極端情況下LNG是否會(huì)造成嚴(yán)重后果進(jìn)行了試驗(yàn)研究。
Although LNG storage equipment and the LNG fuel system are proven to be of high stability, we underwent testing procedures in order to examine the possible threat of LNG danger under some extreme conditions.
LNG氣瓶強(qiáng)度很高，為了將其破壞造成LNG大量泄漏的情形，我們利用炮彈將其擊穿，其結(jié)果僅僅是，瓶中所有的LNG快速噴出，幾分鐘后就已飄散殆盡，沒(méi)有造成任何危害；（字幕：本試驗(yàn)僅用于評(píng)估極端工況下LNG的危害，實(shí)際發(fā)生的概率極低）
LNG storage equipment is both sturdy and resilient. To observe the near-impossible circumstance of an LNG cylinder being broken in a serious accident, we intentionally pierced it using a weapon. After a large volume of LNG leaked from the cylinder into the air, it did not bring forth any damage.
(Subtitle: this experiment estimated the damage LNG may bring in extreme conditions; the real probability is very low.)
 
在更極端的情況下，我們?cè)贚NG氣瓶周圍布滿火源，并將其擊穿。可以看到，LNG大量泄漏后遇到明火并沒(méi)有發(fā)生爆炸，而僅僅形成持續(xù)時(shí)間和范圍都極為有限的燃燒。
（字幕：本試驗(yàn)僅用于評(píng)估極端工況下LNG的危害，實(shí)際發(fā)生的概率極低）
In a more serious situation, we scattered fire sources around an LNG cylinder and then attempted to break it open. Our observations led us to the conclusion that the LNG will not explode even in the event of leakage combined with an open flame; it simply forms a jet fire in a very limited range.
(Subtitle: this experiment estimated the damage LNG may bring in extreme conditions; the real probability is very low.)
作為對(duì)比，我們來(lái)看看LPG泄漏遇到明火的后果，由于LPG密度大于空氣，所以泄漏后會(huì)在地面聚集，很難飄散，遇到明火更可能發(fā)生劇烈爆炸。
By comparison, let’s consider the result of an LPG leak when it is dropped directly onto an open flame. Since the LPG concentration is denser than air, the flammable gas cloud will form around to the leak’s location, not dispersing so rapidly, and it will cause a higher possibility of explosion in a situation with an open flame
 
那么一旦發(fā)生LNG火災(zāi)，應(yīng)該怎樣應(yīng)對(duì)呢？大量試驗(yàn)結(jié)果表明，干粉和泡沫可以對(duì)LNG火災(zāi)進(jìn)行有效的控制和撲滅，防止火災(zāi)擴(kuò)散和蔓延。
So, what treatment shall we take in case of a fire by LNG? Research has shown that dry powder and foam can effectively control and extinguish LNG fires and prevent fire spreading。   
 
LNG作為車輛、船舶的燃料，已經(jīng)經(jīng)過(guò)了多年的探索和發(fā)展，無(wú)論是設(shè)備還是系統(tǒng)的安全設(shè)計(jì)都日趨完善。在LNG發(fā)展歷史上，LNG運(yùn)輸船安全運(yùn)行了50年，LNG汽車安全運(yùn)行了20年，LNG燃料船舶安全運(yùn)行了10年，沒(méi)有發(fā)生過(guò)LNG燃燒或者爆炸導(dǎo)致的人員死亡事故。美國(guó)運(yùn)輸事故管理局曾經(jīng)報(bào)告稱：“與汽油、酒精等燃料相比，20年來(lái)，LNG有著最好的安全記錄。“
For years, LNG has been actively researched as a viable fuel source in both vehicles and vessels. Its ongoing development has been perfected for its role in both small devices and in larger systems, like manufacturing. Throughout its history, LNG has quite an impressive safety record. LNG transportation ships have been safely operating for the past 50 years, LNG vehicles have been safely operating for the past 20 years, and LNG vessels have been safely operating for the past 10 years. So far there has not been any casualty report showing an LNG-caused incident resulting from the combustion or explosion of the LNG fuel itself. A recent Transportation Security Administration report stated that, “Over the past 20 years, LNG has the best safety records, in comparison to other fuels like as gasoline and alcohol.”
大量的工業(yè)應(yīng)用和科學(xué)試驗(yàn)表明：LNG是一種清潔環(huán)保的新型燃料，是一種安全可靠的綠色能源。LNG安全性高、可獲得性強(qiáng)，浙江石油有限責(zé)任公司作為浙江海油統(tǒng)一經(jīng)營(yíng)和管理氣電板塊的全資子公司，秉承“奉獻(xiàn)清潔能源創(chuàng)造美好生活”的宗旨，將一如既往的為L(zhǎng)NG這一朝陽(yáng)產(chǎn)業(yè)的蓬勃發(fā)展而做出更多不懈的努力！
After many extensive industrial applications and scientific experimentation, LNG has proven itself to be an intrinsically clean, environmentally-friendly fuel source. Its exemplary safety records, high safety controls and reliability add to its reputation as a desirable green energy fuel alternative which is readily accessible to consumers. LNG maintains the credits of high leveled safety and availability. CNOOC Gas & Power Group, as the wholly-owned subsidiary of CNOOC, focuses on “contributing clean energies to create a beautiful life”. They will continue pushing for the forward development of this very promising modern fuel source!
