Abstract

Energy exports are considered a form of power. Following the Russia-Ukraine conflict, the US, as an emerging natural gas exporter, has strengthened energy transport with its allies. However, quantitative analysis of how geopolitical events influence the US's exercise of energy power remains an underexplored area. In this study, we used Automatic Identification System data and US ally relationship data to explore the spatial impacts of the Russia-Ukraine conflict on global liquefied natural gas (LNG) maritime transport and changes in US transport patterns before and after the conflict. The results show that the conflict has tightened US alliances. Transatlantic shipping activity increased the most during the time of soaring global LNG prices, with US treaty allies' coastal areas becoming the most active. Owing to the rerouting of transport ships, traffic through the Panama Canal decreased while Strait of Dover traffic increased, significantly enhancing the US’ transport route coverage to core treaty allies. Our results highlight the potential for future conflict events and emphasize the need to enhance global energy security resilience; prevent LNG from becoming a political tool; and design secure, efficient, and resilient national energy policies.

让船只掉头：俄乌冲突重塑美国液化天然气海运网络

能源出口被视为权力的一种形式。俄乌冲突后，美国作为新兴的天然气出口国，加强了与盟国的能源运输。然而，对地缘政治事件如何影响美国行使能源权力的定量分析仍是一个尚未充分开发的领域。在本研究中，我们利用自动识别系统数据和美国盟友关系数据，探讨了俄乌冲突对全球液化天然气（LNG）海上运输的空间影响，以及冲突前后美国运输模式的变化。结果表明，冲突加强了美国的联盟关系。在全球液化天然气价格飙升期间，跨大西洋航运活动增加最多，美国条约盟国的沿海地区最为活跃。由于运输船改道，通过巴拿马运河的运输量减少，而多佛尔海峡的运输量增加，大大加强了美国对核心盟国的运输路线覆盖。我们的研究结果凸显了未来发生冲突事件的可能性，并强调了加强全球能源安全复原力、防止液化天然气成为政治工具以及制定安全、高效和有复原力的国家能源政策的必要性。

期刊介绍： Ocean & Coastal Management is the leading international journal dedicated to the study of all aspects of ocean and coastal management from the global to local levels. We publish rigorously peer-reviewed manuscripts from all disciplines, and inter-/trans-disciplinary and co-designed research, but all submissions must make clear the relevance to management and/or governance issues relevant to the sustainable development and conservation of oceans and coasts. Comparative studies (from sub-national to trans-national cases, and other management / policy arenas) are encouraged, as are studies that critically assess current management practices and governance approaches. Submissions involving robust analysis, development of theory, and improvement of management practice are especially welcome.
