Projects and activities


Equipment carrier

Development of a universal multi-equipment carrier for marine industrial use in water depths up to 6.000 meters. Built of non-magnetic fiberglass, designed for use in extreme situations, versatile and extremely rugged. The equipment rack is separable, set up quickly and can be used as versatile and almost on all types of vessels. The default carrier is equipped with an online data communications and telemetry unit, as well as sonar and echo sounder.

EM Profiler

Development of a electromagnetic profiling system for high-resolution in-situ-measurements in marine systems. Design, development and realization of a fully equipped pressure housing (embedded system, network components various power and communication interfaces) with real-time communication link of standard signal transmission cable (armoured coax-cable up to 10.000m).

2G magnetometer

Installation and adaptive advancement of the cryogenic magnetometer 2G ENTERPRISES 755 HR. Programming, visualization and remote monitoring. Implementation of a cooling system (- 20°C) for measuring ice cores. Production of a module for the automatic measurement of the sample range. Installation of a compensation mechanism for the improvement of the zero-field.
Samples placement

Samples placement

Conception, planning and production of an automatic sample placement for the 2G cryogenic magnetometer. Adaptation at an existing measuring system and programming. Scriptfile modules enable autonomous measurements for up to 96 specimens.

Logging systems

Development of different and universally applicable logger systems for measuring magnetic susceptibility and electrical conductivity. This makes it possible to perform automated high-resolution core measurements on already opened or on whole cores. Integration of various non-contacting and ring sensors. Programming of the control and evaluation software.


Construction and documentation using a modern CAD system in 2D and 3D technology. Technical drawings and working models, support of entire production process and start-up.
