Subsea cables are the unseen infrastructure powering 95% of global internet traffic and connecting the fast-growing web of offshore wind, interconnectors, and transmission grids. At Calash, we are tracking how this critical network is hitting a breaking point.
As networks expand, so do the risks. Telecom cable failures cost $1–3m per incident, while power cable repairs can exceed $100m, with outages lasting months. With 70 new telecom systems coming online by 2027, Calash market analysis suggests fault frequency will only keep rising.
The Bottleneck
– Vessel Scarcity: Repair vessels are in extremely high demand.
– Rising Overheads: Day rates and mobilisation costs continue to climb.
The Calash Perspective: Innovation as a Solution
However, there is a massive opportunity for cost-saving. For certain repairs, AUVs, USVs, and ROVs are already reducing subsea IRM costs by up to 70%. A recent WHOI deployment in Buzzards Bay proved how autonomous tech slashes vessel time on telecom cable inspections.
The tech is here. The case is made. It’s time to invest in the service capability we all rely on.
