Applying lessons from telecoms cable outages to the power cable industry
19 April 2023
Our Permitting & GIS Manager Brian Perratt, recently had an article published in PES Wind magazine. You can read the article as printed in the publication here, or carry on to read an introduction below.
Submarine telecoms cables have an average of 210 faults per year on the global infrastructure, the vast majority of which are caused by external aggression such as fishing and anchoring.
Many of the increasing network of power interconnector, array and export cables follow similar routes or are in similar areas as the shallower water telecoms cables. We can therefore be reasonably confident that the same threats that cause outages on telecoms cables have the potential to have the same impact on power cables. With cable damage accounting for as much as 80% of insurance claims for offshore wind farms and individual cases known to have caused losses of £10 million when lost output and repair costs are combined, it’s an issue that can’t be overlooked.
