Inland water structures such as ship locks, bulkheads and other structures such as dams serve the purpose of securing inland waterways and keeping them operational. Here, these structures present particular challenges to the operators to ensure maintenance and service.

The field of inland waterways includes not only traditional services but also additional services such as ship bottom inspections.

Remotely operated underwater vehicles must be navigated and guided by operators from a remote position.

As positioning underwater is subject to other rules than on land, it is difficult for current solutions to robustly and plausibly determine the precise position of the device and the exact line of sight of the attached camera systems. Therefore, we continuously develop advanced solutions.

Individual positioning is a prerequisite for the geo-referenced surveying of underwater objects, e.g. by means of modern laser technologies and hydroacoustics methods, for which a great number of sensors is available in different qualities and resolutions up to the µm range.

We will be happy to provide you with an overview of your options.

Interesting coastal areas and port facilities are subject to regular surveying underwater. With the recorded data, it is not only possible to obtain historical data, by means of which long-term changes of the underwater structures can be detected and analyzed; they also facilitate the detection of changes in the fundamental structures in real time.

It is therefore possible to quickly detect and report harmful objects, damages or hazards in the known, surveyed areas underwater. The prerequisite of this application are comparative data by means of which the sensors can make direct decisions.
