Ordnance clearance onshore

We have all heard the term dud. Throughout Europe there are still munitions of all kinds from the First and Second world war in the ground, which have not yet exploded but are still highly explosive. Alone in Germany several thousand tonnes of munitions are uncovered every year. Our specialists with a military background have been contributing to the safe disposal of this legacy explosive ordnance since 1978.

Apart from salvaging and destroying ordnance, our specialisation and technology allow a detailed analysis of the ground and the targeted locating of legacy ordnance even before the start of hydraulic and structural engineering work. Our experts use all their expertise, flair and technological understanding to your advantage and for your safety. We use the latest technology here, which we are constantly developing further with renowned universities and our partners. As experts in this area, we actively cooperate in the technical and scientific developments in the area of legacy ordnance clearance. Boskalis is DAKKS-accredited for all techniques and technologies used.

Using various geophysical processes, we locate anomalies (suspicious objects) and combine different measuring techniques in order to be able to identify and classify objects without doubt. From the complex analysis of the acquired data, our experts arrange the necessary actions and meticulously plan them.


Boskalis is a general contractual partner for various ordnance clearance services throughout Germany, member of Güteschutzgemeinschaft Kampfmittelräumung, the German ordnance clearance safety organisation, and is RAL-certified.

In addition, we are accredited for the application of modern inspection techniques in ordnance clearance and are ISO-certified.
