Preparation and Execution of a Bomb Detonation near Oranienburg
A 250 kg bomb with active long-term detonator was discovered during hydraulic circulation drilling operations in the Havel River near Oranienburg.
Als Besonderheiten ist hier zu nennen:
The bomb was located in the water and had to be laid open, with supports being installed so it would stay in place, and then identified by divers.
The bomb had an active long-term detonator that would make it impossible for the Brandenburg Munitions Recovery Service (MBD) to disarm it.

Salvage of Boulders in Bremen
Boulders in the Weser River bed had to be removed because they were a disturbance for the shipping. This project was carried out in partnership with the Company Worthmann in Bremen.
Selective Recovery of Warfare Agents (UXO)with Hydraulic Circulation Drilling in Wilhelmshaven
Selective clearing of 170 suspicious points along a cooling water structure in Wilhelmshaven, with deep sounding in parts by means of hydraulic circulation drilling to investigate even deeper target points.
This work had to be carried out in accordance with the tidal activity. Other challenges included the constant possibility of bad weather conditions caused by storms and high wave activity common in this coastal area.
Clearance of Buried Warfare Agents (UXO).
Clearance of sites suspected of having buried warfare agents (UXO) on a property of Rheinmetall AG.
Special protective measures with respect to respiratory equipment and body protection; protective clothing, breathing masks, and hand and foot guards were used. Moreover, one could only enter onto the worksite after extensive controls. All personnel worked under constant supervision.
Clearance of Warfare Agents(UXO)from the Weser River near Nienburg
Divers investigated and recovered 650 points (Survey target list) suspected of containing warfare agents in four sections of total length 4.50 km along the Weser River near Nienburg. Furthermore, approx. 10,000 m3 of riverbed were removed from the river, sifted and dumped. We executed this project in conjuction with the Dutch company Heuvelman Ibis B.V.
This project had several special features, including the high river current, shipping activity, fluctuating water levels, and nocturnal work. Protective measures included but was not limited to: construction of a pipe made of anti-magnetic material to protect against the current, sufficient illumination, floating technology with stilts(spudlegs), guard rails, and life jackets.
Removal of Remains from WW II in Bremen (Demolished Bridge).
Removal of pieces of the Bürgermeister-Smidt-Brücke (Mayor Smidt Bridge) over the Weser River in Bremen that was destroyed during the war. Old pieces of bridge on the riverbed had gradually become an impediment to shipping and therefore had to be removed by our divers. For this purpose, the riverbed was plumbed for height by a sounding vessel and obstacles that were lying too high were marked on a chart. Our divers serviced the charted regions and removed these old pieces of bridge using underwater torches and crane technology.
This work proved to be difficult for the divers because of poor visibility under water, the current, shipping and the tides.
Recovery of Casks of Poisonous Gas from the Bed of the Baltic Sea near Lübeck.
Our divers were deployed to look for and examine 15 containers with unknown contents from the bed of the Baltic Sea. Since these containers were assumed to contain poisonous gas, extensive protective measures had to be taken for the persons on board, the divers and the coastal region. The divers’ work was accompanied by an underwater remotely operated video camera (ROV) so that the specialists on board could closely inspect the contents of these containers. Since the presence of munitions could not be ruled out, the divers also took along an underwater probe.
Here, the most important distinctive feature was the presence of poisonous gas. Consequently, both the current and the wind direction had to be just right so that the coastal regions would not be in any danger in the event of an accident. The persons on board also had to wear special protective clothing (Breathing equipment). Since the water was 23 m deep, the divers only had a limited amount of time available for their work.
