Martin Sulanke has been a professional diver for 36 years. He works on the "Atair". In an interview on board, he explains what his job entails and why it can be dangerous underwater. "I originally come from deep-sea fishing," says Sulanke, who wears a white stubbly beard, a silver earring and a red cap. The 61-year-old, who now lives in Bad Schwartau near Lübeck, comes from the former GDR. He later joined a hydraulic engineering company and trained as a professional diver. After the end of the GDR, he joined the Federal Maritime and Hydrographic Agency (BSH). He has served the authority for 34 years, which...

The Federal Maritime and Hydrographic Agency plays a key role in ensuring safety in German waters. Divers from the agency search for underwater obstacles in the Elbe. On the Elbe, between Hamburg and the estuary. A northern German autumn day, the water is grey-brown, sometimes it rains. Large ships pass by, heading for the Hanseatic city or the North Sea. A boat rocks on the waves, "Ruden" is written on the bow. Three hoses in blue, yellow and orange, wound around each other in a spiral, lead from the boat into the depths. They lead down to Tjark Lange. The diver is travelling towards the bottom. The blue hose is used to...

Just one ping: WTD 71 revolutionises sonar performance analysis

Just one ping: WTD 71 revolutionises sonar performance analysis

Gepostet von | 20 Mar 2025 | , , | 0

Submarine hunting is a highly complex business. In order to remain at the cutting edge of technology, WTD 71 is developing a demonstrator for modern sonar performance analysis. Sonar performance analysis is an important tool in submarine hunting and in determining the betrayal range of own submarines against possible enemy detection. It predicts how reliably and up to what distance a potential underwater target can be detected by an active or passive sonar system. In the case of an active sonar system, a sonar ping is emitted at a specific source level. It travels through the water and loses intensity due to various propagation effects, resulting in a loss of propagation. After reflection at the...
