The UK is the world leader in offshore energy generation with 5GW of installed capacity and ~15GW consented or in construction. As farms grow and move into remote, deeper waters subsea cable resilience has a critical impact on security of supply and cost of electricity. Electricity is delivered via redundant buried power cables, however this infrastructure is expensive to fix and experiences the worst hazards of subsea life such as anchor drag and seabed movement. This leads to exposed or free spanning sections which can result in failure and a complicated repair - with the worst case being windfarms sitting idle unable to export their electricity. The situation is exacerbated by current technology being unable to adequately locate faults. The MIDAS project brings the known advantages of fibre optic sensing to subsea cabling, developing a product and service which will reduce failure occurences and in the worst case scenarios will immediately identify and locate an issue (a significant improvement on current technology). MIDAS, integrated in a system-wide Operations & Maintenance strategy, will also provide operators with always-online site-wide ocean wave conditions which will improve safety and lower the cost of energy through more efficient marine vessel planning.
