Summary

Summary: 
A French company specialized in marine electromagnetic has developped an innovative sites investigation solution which can be used for many applications such as geophysics, impact assessment or buried objects detection including non-ferrous objects. The company wants to develop the use of electromagnetic services and imaging and is looking for partners to deploy the solution during site investigation marine in a commercial agreement with technical assistance.

Description

Description: 

The company was founded in 2015 by 2 experts in electromagnetics applied to geoscience. They develop instrumentation, theoretical calculations and modelling in marine electromagnetics for site investigation. The SME offers a complete and adapted solution to client needs from instrumentation, implementation to data processing.

Electromagnetism is used since a long time for land exploration, but the French SME has developed it for marine environment.
This electromagnetic measurements solution differs also from existing technologies for underwater investigation and enables to image what is not visible with conventional technologies.

The electromagnetic measurements can be passive or active:

- with passive measurements, marine electromagnetics is a key measurement for corrosion control, cables and infrastructures impact assessment, or the quiet detection of vessels.

- with an active signal, it is possible to localize objects such as archaeology, Unexploded Ordnance (UXO), pipelines or cables and to image the electrical resistivity of the medium for geophysical studies. The resistivity is the capability of materials to resist to a current flow.
Thus, marine resistivity imaging is an accurate technique to determine the geological structures of the marine substratum and the objects within.

The electromagnetic systems can be used both in sea and fresh waters. The system is composed of a fish (1.5m length, 20cm diameter) towed by a surface vessel, followed by a sensor cable. The instrument is in a dipole-dipole configuration, which allows good penetration and resolution. Electrical current is used as an electromagnetic source that enables to characterise the geophysical features, or to detect man-made objects present in the area.

The registered data by the sensors are displayed in real time on the ship and are saved on computer.

Marine electromagnetics can be used in several fields and markets:
- marine renewable energy
- oil and gas
- dredging
- objects localization for archeology, defense, construction (ferrous and non-ferrous)
- geophysics (including hard rocks)
- cables routes
- electromagnetic barriers

The company would like to find partner in those fields and markets to use the electromagnetics solutions for marine site investigations. The type of partnership will be a commercial agreement with technical assistance.

Advantages & innovations

Cooperation plus value: 
Electromagnetics measurements are mainly used for land exploration but this new solution of marine electromagnetics including resistivity measurements provides a new insight in marine geophysics. The dipole-dipole configuration allows good resolution and penetration. Resolution and penetration are adapted to the defined target by the user, from some meters down to 40m in the substratum. The system is easy to use: - near seafloor bottom towed instrument - independent of water depth, - can be used on small vessels (10m), - the size of the fish is easily handled by 2 persons and sensor cables are deployed by hand. The electromagnetic measurement creates no damage on the environment given that the voltage involved are low. The new proposed solution relies on technology giving unprecedented performance in the resistivity modelling, which gives unique information to lower the risks on ground models and projects, particularly in areas where acoustic techniques cannot provide enough information, because of gas or acoustic masks for example. As for objects detections, the proposed technology provides a unique way to detect ferrous and non-ferrous buried objects in the marine environment.
