Adaptivity

One of the most frequently used sensors for AUVs is a sidescan sonar. SeaCat features an integrated Edgetech dual-frequency sidescan sonar as standard equipment. It operates at 300 kHz and 800 kHz and permits a swath width of up to 300 m.

Almost every task of an underwater measurement system requires additional and different sets of sensors. The SwapHeadTM of SeaCat allows changing the nose section of the AUV within minutes. The water-flooded section is connected to the AUV by eight screws and standard underwater connectors. This versatile and flexible concept allows for a multitude of (sequential) applications. For example, the AUV may perform a hydrographic survey using the Survey Head and subsequently perform a video inspection of unknown objects using the Inspection Head.

 

Examples of SeaCat SwapHeadsTM:

Survey Head - Multi-beam echo sounder for bottom topology mapping
Inspection Head - Video camera mounted on a pan-tilt frame for video inspection
Water Quality Head - Systems for measuring water quality like dissolved oxygen, hydrocarbons,
dissolved organic matter, turbidity, etc.
Tunnel Inspection Head - Providing a look into the inside of water supply ducts
Harbour Inspection Head - High-frequency multi-beam echo sounder and video camera mounted
on a rotary unit enable the mapping of vertical structures and ship hulls in great detail
Geomagnetic Head - A highly sensitive magnetometer can be towed behind the AUV.
Subbottom Head - A high-quality subbottom profiler is built into this device.
