Abstract

Liquified Natural Gas (LNG) has recently been used as a new fuel in the maritime sector. Besides the preceptive studies related to the safety in the use of LNG and its consequences on people, infrastructure, and the environment, recent studies have addressed the reliability of bunkering operations. These studies do not include aspects which influence the reliability of the bunkering operation such as the effect of environmental conditions and human behavior as key factors for the reliability of the whole process. This paper presents a reliability model for bunkering operations which includes both effects. A sensitivity and uncertainty analysis of the results obtained is also included. Results and important findings are supported by an application example focused on bunkering truck to ship operation performed in a Spanish port. The results show that BURI is normally high close to 97% but it can decrease to a value close to 25% for adverse environmental conditions or 68% depending on human stress, experience and motivation.

考虑不确定性的液化天然气加注作业可靠性指数

液化天然气（LNG）最近已作为一种新燃料应用于海洋领域。除了与液化天然气的使用安全及其对人员、基础设施和环境的影响有关的前瞻性研究外，最近的研究还涉及加气操作的可靠性。这些研究并不包括影响燃料加注操作可靠性的方面，如环境条件和人类行为对整个过程可靠性的关键因素的影响。本文提出了一个包括这两种影响的加油作业可靠性模型。本文还对所得结果进行了敏感性和不确定性分析。结果和重要发现得到了一个应用实例的支持，该应用实例侧重于在西班牙港口执行的加油车到船操作。结果表明，BURI 通常高达 97%，但在不利的环境条件下，BURI 可降至 25%或 68%，这取决于人的压力、经验和动力。

期刊介绍： The broad scope of the journal is process safety. Process safety is defined as the prevention and mitigation of process-related injuries and damage arising from process incidents involving fire, explosion and toxic release. Such undesired events occur in the process industries during the use, storage, manufacture, handling, and transportation of highly hazardous chemicals.
