【摘要】：随着经济的迅速发展,我国对不可再生能源的消耗持续攀升。为了改变能源结构和加强环境保护,我国开始大力开发利用高效、洁净、方便、安全的天然气能源,但是许多天然气产地与我国远隔重洋,因此,我国液化天然气(LNG)船舶运输得到了飞速的发展。然而,LNG船舶运输在为我国低碳经济和节能减排带来不可替代作用的同时,也给我国的生命、经济、环境带来了巨大的风险。目前,我国LNG船舶运输的风险评价标准尚未建立,现阶段所采用的风险评价标准主要依据国外相关标准,而这些标准大多是关于天然气管道和地质灾害方面的研究,这虽然可以参照,但相距我国具体国情和LNG船舶运输情况尚有很大差距。本文旨在研究LNG船舶的风险评价标准,对我国进一步提高LNG船舶运输的安全管理水平及降低事故风险做出应有的贡献。首先,简单地介绍了风险的概念并明确风险分类,风险可分为生命风险、经济风险和环境风险,而生命风险又可分为个人风险和社会风险。本文主要的研究对象是LNG运输船舶的生命风险评价标准,即LNG运输船舶的个人风险评价标准和社会风险评价标准。其次,充分地查阅了国内外风险评价标准的研究现状,在此基础上,汇总了国内外风险评价标准的研究方法,同时在现有的风险评价标准界定原则以及关于风险评价标准必须注意的一些问题等方面,提出风险评价标准的界定原则。再次,认真地总结了定性和定量的风险评价标准界定方法的理论依据,依据这些理论,提出了多种个人风险评价标准和社会风险评价标准的研究方法。最后,基于已有LNG运输船舶历史事故数据,选取具有代表性和可行性的方法界定出了我国LNG船舶的个人风险评价标准和社会风险评价标准。
[Abstract]:With the rapid development of economy, the consumption of non-renewable energy in China continues to rise. In order to change the energy structure and strengthen the environmental protection, our country began to develop and utilize highly efficient, clean, convenient and safe natural gas energy. The ship transportation of liquefied natural gas (LNG) in China has been developed rapidly. However, LNG shipping not only brings irreplaceable effect to low-carbon economy, energy saving and emission reduction, but also brings huge risks to our life, economy and environment. At present, the risk assessment standard of LNG ship transportation in China has not been established. At present, the risk assessment standards adopted at this stage are mainly based on the relevant foreign standards, and most of these standards are related to the study of natural gas pipelines and geological hazards. Although this can be referred to, there is still a big gap between China's specific national conditions and LNG shipping situation. The purpose of this paper is to study the risk evaluation standard of LNG ships, and make due contribution to improving the safety management level of LNG ships and reducing the risk of accidents in China. Firstly, the concept and classification of risk are briefly introduced. Risk can be divided into life risk, economic risk and environmental risk, and life risk can be divided into individual risk and social risk. The main research object of this paper is the life risk evaluation standard of LNG transport ship, that is, personal risk evaluation standard and social risk evaluation standard of LNG transport ship. Secondly, the research status of risk evaluation standards at home and abroad is reviewed, and on this basis, the research methods of risk evaluation standards at home and abroad are summarized. At the same time, the definition principle of the risk evaluation standard is put forward in the aspects of the existing definition principle of risk evaluation standard and some problems that must be paid attention to in the risk evaluation standard. Thirdly, it summarizes the theoretical basis of qualitative and quantitative risk evaluation criteria, and puts forward a variety of personal risk evaluation criteria and social risk evaluation criteria research methods. Finally, based on the historical accident data of LNG ships, the personal risk evaluation criteria and social risk evaluation criteria of LNG ships in China are defined by the representative and feasible methods.
