Security of International Submarine Cable Infrastructure: Time to Rethink?

Abstract

Today's submarine cables form the backbone of an international network and are of strategic importance to the global economy. This network is designed to be resilient, however, there are threats that can disrupt the activities that we take for granted, such as the internet, telephone, use of ATMs and flight booking. These threats include those that are manmade such as fishing activities, ships anchors and emerging acts of piracy through to natural events such as earthquakes and landslides. The cable owners undertake activities during the planning, implementation and operation to minimize the impact of such threats. However when faults do occur it is important that they are repaired as soon as possible. This paper discusses some of the issues and looks at the role of UNCLOS and government in the repair of cables. It also covers examples where emergency repairs have been delayed due to the requirement for permits and suggests opportunities for improvement.
