Ships operating in conflict areas face the threat of sea mines. Modern influence mines have sensors to detect, among other things, underwater sound, pressure and magnetic and electric fields. This data is combined and processed and leads to detonation or not. Dutch naval vessels are also deployed to conflict areas and therefore run an increased security risk. The physical fields that a ship produces, and that can be observed by a sensor, are called signatures. For example, we speak of the electrical and magnetic underwater signature, by which we mean the 3D field distribution around the ship. Minimizing these signatures leads to a reduction of the mine threat. An example: the magnetic signature is mainly caused by the fact that a ship is made of steel and is located in the Earth’s magnetic field. This interaction leads to a magnetic disturbance that can be reduced with a counterfield by using electrical coils integrated in the ship, the so-called degaussing system. To effectively reduce the magnetic signature it is necessary that the correct electrical currents flow through these coils. This example illustrates that much research needs to be done to reduce the risk of influence mines. For example, there is a need for a good model that describes the magnetic signature of a ship as accurately as possible, experiments are needed to validate and improve such a model, such a model can help to better design future ships, and models are needed to estimate the risk reduction through the application of signature reducing measures. Technologies such as the use of drones, the application of AI and the use of GPUs to accelerate calculations also contribute to this.
