Subsea Cable Maintenance Strategies.

Damaged subsea power cables can result in significant revenue losses for offshore wind farms.  Latest data from the insurance industry suggests that subsea HV power cable issues represent approximately 80% of claims by volume and  75% of payout value in offshore wind.

  • 77% of damages are caused by 3rd parties , mainly ship’s anchors and fishing gear
  • 14% of damages are caused by natural hazards, like strong currents , shifting sediments or rocks and, incredibly, evidence has shown fish bites on several cables
  • 9% due to other causes such as internal faults , undermined root causes, and unexplained malfunctions

Mario’s expertise supports subsea cable owners and insurance underwriters in developing new solutions to minimise the impact of potential cable failures.
