| With the development of Chinese economy and the improvement of people's living standards, awareness of environmental protection and sustainable development is becoming more and more strongly.LNG,with the good characteristics of lower transportation costs,clean,energy conservation,is gradually been widespread concerned.Also,the growth of LNG demand is accelerating. According to customs statistics,China imported 5.532 million tons of liquefied natural gas in 2009,3.34 in 2008,2.91 in 2007.Until now,the LNG consumption of China is much lower than the average of the world,because of energy transformation,the demand of LNG is increasing. Supply and demand gap in 2020 is expected to reach about 150 billion cubic meters, the proportion of net imports will reach 40%. Therefore, our LNG's transportation will reach a golden period.However, with the increasement of transportation,the risk is becoming more, LNG is a natural gas with flammable and explosive nature and high degree of uncertainty.Recently, Vicious incidents occurred LPG ships, the healthy development of LNG transport is suffering a serious threat. China's LPG imports mainly depend on water transport.Whether the waterborne transportation environment is good or not, directly affects the LNG ship navigation safety. So, the safety evaluation on the LNG ship navigation is very importantThis article starts from the actual navigable circumstances of the shenzhen western port,under the direction of FSA,through the navigaton environmental analysis of the port and identification the risk factors for traffic safety,establishing the navigable safety evaluation index system,combinating the AHP and fuzzy comprehensive evaluation to evaluate the safety and security. By calculating, whether the navigation of the shenzhen western port is safety or not is determined. For the LNG ship navigable safety,it is an effective evaluation method. The real solution to the problem of navigable safety has a certain significance. |
