Nord Stream 2 route checked for obstructions
iSURVEY has completed a 30-day geophysical seabed survey for Allseas for the Nord Stream 2 pipeline project in the Baltic Sea.
The company chartered theSeaZip FIX vessel for the campaign, assuming full responsibility for the vessel, marine, survey, processing and reporting elements of the program.
This involved identifying any obstructions or hazardous seabed features over a 40-km (25-mi) section of the route in the German sector, ahead of pipelay anchoring and mooring operations.
iSURVEY conducted ROV operations, with a moonpool deployment frame providing a retractable mounting location for vessel-based attitude monitoring, positioning and geophysical sensors.
Combined multi-beam echo sounder and side scan sonar systems were used throughout the campaign, along with a towed magnetometer/gradiometer system.
