Västra Frölunda – MMT (Sweden) will perform two surveys this summer in the Baltic Sea for Nord Stream AG.
The campaign will assess the impact of the two parallel Nord Stream gas trunklines on near-seabed currents in the Finnish section through observation of potential localized scour and sedimentation.
To determine seabed sediment features, obstructions and sediment characteristics the company will use a remotely operated TV-mounted side scan sonar system.
The company will then conduct a camera-based study of benthic fauna on hard sea bottom south of the Sandkallan Natura area, along a 5-km (3.1-mi) long transect starting from the pipeline and heading north toward the Natura area.
MMT will use the survey and ROV vessel IceBeam for the assignment.
