The Department of Defence in Ireland and the Directorate for Defence of the Ministry for Foreign Affairs in Iceland jointly hosted an Advanced Research Workshop on Undersea Communications Cables and Crisis Management from 3–5 December. Supported by the NATO Science for Peace and Security Programme, the workshop aimed to strengthen collaboration and dialogue on safeguarding critical undersea infrastructure.

Held in Ireland, the event provided a platform for subject matter experts from 15 countries—including researchers, policymakers, government officials, and industry leaders—to share insights and develop best practices. Discussions focused on recent developments, challenges, and strategies to enhance the security and resilience of this vital infrastructure.

Professor Caroline McMullan from Dublin City University (DCU) Business School presented a research-informed presentation on Emerging Lessons in Crisis Management and Preparedness. Drawing on her extensive expertise, Professor McMullan explored key learnings from crisis management literature and case studies, emphasizing their relevance to the unique challenges faced in protecting undersea communications cables. Her presentation provided a framework for delegates to apply these lessons in managing risks and preparing for potential crises that could impact this critical infrastructure.

Reflecting on the workshop’s significance, Ms. Jacqui McCrum, Secretary General of the Department of Defence in Ireland, stated:

“Ireland and Iceland’s waters are home to critical infrastructure that is of both national and global significance. But we cannot rely on our geographic isolation for our security, nor isolate ourselves from world events. We have a responsibility, through our defence policy, to invest in the defence of the state, to protect our citizens, our values and our sovereign interests, and to continue to contribute to international peace and security.”

Ambassador Sturla Sigurjónsson underscored the importance of collaboration:

“Undersea communications cables are essential to our modern digital economies, not least for island countries like Iceland and Ireland. The security and resilience of this infrastructure require collaboration between countries as well as between policymakers, industry, defence forces, and academia. Developing a better collective understanding of the issues affecting the maritime environment will help to improve security and crisis management of undersea infrastructure.”

While most undersea cable faults arise from natural or accidental causes, the current geopolitical landscape has increased concerns about their potential vulnerability to sabotage or interference by malicious actors. This workshop facilitated a vital exchange of knowledge and experiences, with Iceland and Ireland taking a proactive role in fostering regional and international dialogue to strengthen the resilience and security of undersea communications infrastructure.

Professor McMullan’s contributions offered delegates critical insights into crisis preparedness and management strategies, ensuring the discussions were informed by both academic research and practical applications. Her involvement exemplified the essential role of academia in addressing complex global challenges.
