Seabed Surveillance and Underwater Structures Inspection with Remotely Operated Vehicle Power Ray

The marine ecosystem is necessary to be monitored as it is exposed to externalities and pollu-tants that affect biodiversity and the state of the underwater structures. There is a demand for a better, more dynamic, and safe monitoring approach to underwater research and inspection. The unmanned underwater vehicles are becoming a reachable and intuitive tool for underwater inspection, such as for the inspection of the marine hull of vessels, bridges, foundations, piers, pylons, and other support struc-tures in ports. The main advantage of the use of the remotely operated underwater drone is cost and timeefficiency, as they allow to obtain information in a fast and safe way in real-time. In this paper we investigate the possibility of the use of a remotely operated underwater drone Power Ray for seabed observation and underwater structures inspection. It describes the results of the field research collected from the use of low-cost underwater drone Power Ray. The data collected with an underwater drone pre-sents footages of different underwater structures and areas in order to document the seabed state and underwater structures. Additionally, this article provides an overview of the problems in underwater in-spection and monitoring, and possibilities offered by remotely operated vehicle Power Ray in solving them. The results of the paper are not unique to working with a low-cost drone, but are illustrative of the challenges and problems that new users are likely to encounter when using this technology.
