National Grid planned periodic inspection surveys of the HVDC and HVAC cable systems during the operational phase of Eastern Green Link 4. Surveys would include vessel-based and geophysical inspections of the subsea HVDC cables and periodic inspections along the onshore cable route to monitor burial depth, detect exposure or damage, and inform any remedial actions. These activities are described as recurring during operation (i.e., once the link is in service around 2033) and would be used to confirm cable condition and integrity and to target any follow-up maintenance or protection works.
