With　the　proposal　of　the　development　goals　for　pollution　control,　the　use　of　liquefied　natural　gas　(LNG)　as　a　clean　and　low-carbon　energy　source　has　received　huge　attention　in　the　European　energy　market.　This　study　examines　the　European　LNG　maritime　supply　chain　network＇s　structural　evolution　from　2018　to　2020　using　AIS　data.　Our　analysis　reveals　a　marked　quantitative　increase　in　the　network＇s　scale,　with　European　shipments　climbing　from　695　to　1337　and　cargo　volumes　soaring　from　40,101,000　tons　to　87,129,740　tons,　signifying　annual　growth　rates　of　92.4%　and　117.3%,　respectively.　A　graph　deep　learning　approach　unveiled　enhanced　connectivity　and　community　consolidation　among　European　LNG　ports　despite　the　dispersion　suggested　by　a　slight　density　decrease　from　0.192　to　0.185.　Simulated　attack　scenarios　indicate　heightened　network　robustness　in　2020,　yet　emphasize　the　criticality　of　safeguarding　nodes　like　Sebatta　against　targeted　disruptions.　Addressing　these　insights,　we　propose　policies　focused　on　energy　diversification,　fortified　port　security,　and　adaptive　governance　to　bolster　the　network＇s　resilience　amidst　dynamic　global　conditions.　Our　study　thus　offers　a　strategic　framework　for　managing　energy　trade　complexity,　acknowledging　the　need　for　further　research　on　the　geopolitical　impact　on　network　dynamics　and　vulnerability.
