STAPEM Offshore can also provide various surveys services as:
Land or very-shallow water surveys
Water depth acquisition on profiles
Geophysical survey, sub bottom profile
The sub bottom profiler permits to detect the geological variations in the last sediment layers, few meters below sea bottom. It permits also to visualize the bottom shape, control the water depth and sub bottom sediment layers thickness.
Debris survey with side scan sonar or marine magnetometer
Visual inspection of the sea bed. Debris location and size measurement. The sonar fish is towed on profiles.
The Marine magnetometer survey to identify anomalies present in the site.
The Marine Magnetometer is the best tool for locating metal debris, sunken ships, lost anchors, buried pipelines, and other underwater objects containing ferrous metal that disrupt the Earth’s magnetic field.
Marine magnetometer – towed behind a survey vessel – is used to precisely measure the Earth’s magnetic field; magnetic contour maps reveal anomalies that represent buried ferrous objects.
