Liquefied　natural　gas　(LNG)　is　a　critical　component　of　the　global　sustainable　energy　industry,　with　substantial　implications　for　global　energy　development.　Although　the　maritime　transportation　system　has　played　an　important　role　in　promoting　global　LNG　trade,　it　remains　highly　vulnerable　to　international　political　events,　major　disasters,　and　other　emergencies.　To　better　understand　the　robustness　and　security　of　the　global　LNG　transport　system,　this　study　provides　a　new　analysis　paradigm　for　evaluating　the　robustness　of　the　LNG　transport　network　in　the　face　of　disruptive　events.　We　examine　a　variety　of　network　parameters　for　the　global　LNG　transport　network　between　2013　and　2023　to　capture　changes　in　topological　structure　and　evolution.　Then,　we　introduce　three　centrality　indices　which　can　capture　distinct　characteristics　of　the　maritime　ports　including　connectivity,　transfer,　and　cohesion,　and　combine　these　three　centralities　into　a　TOPSIS　framework　to　achieve　a　multidimensional　port　centrality　for　identifying　essential　ports.　Finally,　we　evaluate　the　robustness　of　the　LNG　transport　network　against　several　sequential　intentional　attacks　using　diverse　strategies.　We　found　that　we　can　loosely　separate　the　collapse　process　of　the　LNG　transport　network　into　three　stages:　initial　collapse,　ongoing　fragmentation,　and　final　collapse.　In　2013,　intentional　attacks　based　on　degrees　and　TOPSIS　centralities　were　the　most　likely　to　cause　the　LNG　transport　network　to　collapse.　In　2023,　intentional　attacks　based　on　betweenness　and　TOPSIS　centralities　are　the　most　likely　to　cause　the　LNG　transport　network　to　collapse,　and　the　LNG　transport　network　is　more　robust　than　it　was　in　2013.　©　2025　Elsevier　Ltd
