Protecting Subsea Cabling

The energy industry is changing. Renewables are on the rise and wind energy is becoming increasingly prevalent. In fact, Britain is set to increase the amount of energy produced from offshore wind farms from 7% to 30% over the next decade.However, offshore wind energy is completely reliant on subsea cabling to deliver power back to land and allow transmission between turbines. If these essential cables become damaged or start to malfunction, it could completely cease production — requiring expensive repair work.Threats to subsea cables are a huge risk to offshore wind farms, one that the renewable
