Erkki Koort, head of the Estonian Academy of Security Sciences, highlights the vulnerabilities of undersea infrastructure in the Baltic Sea following several incidents, including the Nord Stream gas pipeline explosion. Nations are ramping up efforts to secure these vital assets, with NATO forming a special group for undersea cable protection. While preventative measures like sensors and information gathering are crucial, complete protection remains elusive. Emergency response plans are evolving, with Estonia’s Ministry of Climate tasking Elering to prepare for potential repairs of damaged underwater cables.
