How much does cable repair cost?

Repairing a single undersea cable can cost several million pounds and take weeks, depending on the damage and location. This includes locating the fault, dispatching a repair vessel, retrieving and splicing the cable, and re-laying it. The £300m replacement cost for CS Sovereign reflects the high value of this capability.
