A detailed geophysical inspection survey along the operational WesternLink submarine HVDC interconnector began on 2 October 2023. The campaign — executed by dive-support vessel Curtis Marshall — mapped parallel survey lines along the cable route using multibeam echosounder and side-scan sonar to verify seabed condition, burial integrity and detect any exposures or anomalies along the full length of the 390 km route.
