Nearshore Survey

Nearshore Survey AS is a Norwegian hydrographic survey company. It provides precision depth mapping and detailed seabed mapping in lakes, reservoirs, rivers and coastal waters. Services include multibeam bathymetry, route surveys for subsea cables with multibeam, side scan sonar and ROV, positioning of subsea infrastructure, and depth documentation for harbour and fairway dredging. Other services cover reference point surveys, calibration checks against a known surface, RTK-GNSS and USBL positioning, and installation of water level, wind and current sensors.

Surveys are carried out with the company's own vessels and equipment. These include the Askeladden2505 mini survey vessel with a Kongsberg EM2040C multibeam echosounder, a foldable 10 m catamaran, and a Seadoo Spark survey scooter with a NorbitWBMS multibeam for very shallow areas and rivers. Sensor equipment includes an EdgeTech 4200-FS side scan sonar, a Marine Magnetics SeaSPY magnetometer and an Innomar SES-2000 sub-bottom profiler. Customers are projects in planning, construction and infrastructure work that need bathymetric or seabed data, such as dam and reservoir scanning, lake volume calculations and cable route clearance.

The company was founded in 2013 and is registered in Øvre Ervik, Norway, with contact details also listing Bergen. Its work covers lakes, reservoirs, rivers, coastal waters and subsea routes.
