MMT (Sweden) completed a geophysical cable route survey for the Amrumbank West offshore wind farm for Siem Offshore Contractors GmbH. The scope covered the inner array grid cable route and included bathymetric and side-scan sonar survey, sub-bottom profiling, and a magnetometer survey for detection of unexploded ordnance (UXO). Based on magnetic anomalies, additional target inspections were performed using an ROV equipped with a gradiometer array. The reported survey coverage totalled about 550 km within the wind farm area.
