Subsea bomb detection

Muns Techniek is a system integrator for Hydraulic systems and Electrical controls. With more than 25 years of experience we offer Hydraulic and Electric Solutions for projects in the Maritime, Offshore and Industry.


In some waters it is not uncommon to find explosives in the soil. This can be a major problem for dredgers. Our customer asked our assistance to develop a system that was capable of finding these explosives, using a subsea magnetometer.

For this to work, the sensor will have to be near the soil at all times. This means that the sensor will have to be lifted and lowered depending on the changing water depth as the vessel moves along. Our engineers developed the hydraulic system and appurtenant controls to keep the sensor in the right position.


The system is using winches to lower and raise the sensor into the water. Subsequently the sensor remains in the right position to search for bombs in the soil.
