Abstract: The invention relates to an underwater device for capturing images of a seabed with multiple electrical function units, a control program for controlling one electrical function unit, another control program for controlling another electrical function unit, and at least one control device. The underwater device is characterised in that the underwater device is designed such that the control program and the other control program are selectively executable on the same control device or the control program is executable on one control device and the other control program is executable on another control device.

Abstract: The invention relates to an underwater device for capturing images of a seabed, comprising at least one sensor for detecting a sensor value, at least one electrical consumer and an electrical energy source for supplying electrical energy to the electrical consumer. The underwater device is characterised in that, based on the sensor value, it is determined whether a hazardous condition exists for the electrical consumer and an energy distribution unit is provided which disconnects the electrical consumer from the electrical energy source if a hazardous condition exists.

Abstract: An underwater device has a hyperspectral camera for capturing images of a seabed, a first housing part, a second housing part releasably connected to the first housing part in a watertight manner and enclosing with the first housing part a cavity in which the hyperspectral camera is arranged, and an electrical energy storage device for supplying electrical energy to the hyperspectral camera arranged in another cavity, wherein the other cavity is separated from the cavity by a wall section of the first and/or second housing part.
