Recommendation 8

Events like the sabotage of the Nord Stream pipeline have shown that Critical National Infrastructure that is based offshore or beneath the sea can be vulnerable to interference. This is a concern in the North Atlantic, where transatlantic cables are critical lines of communication, as well as in the UK’s own Exclusive Economic Zone. Investment in subsea surveillance like the Multi-Role Ocean Support Ships is welcome, but vulnerabilities remain. We heard that weaknesses in the legal regime governing subsea cables makes them a tempting target for malign actors. The UK Government told us that repair of subsea cables was a matter for the cables’ commercial owners; we are concerned that the UK Government did not have more to say about how such important infrastructure could be repaired in the event of sabotage or failure.
