IMPROVEMENT OF TECHNICAL SUPPLY OF PROJECTS OF ROBOTIZED MONITORING OF UNDERWATER CONDITIONS IN SHALLOW WATER AREAS

The intensification of industrial activity in shallow water areas and the growing requirements for the safety of their use determine the urgency of developing new technologies for monitoring their underwater environment. The monitoring tasks include mapping of the bottom surface, inspection of hydraulic structures, search for sunken objects, control of unauthorized access to protected areas, etc.

A promising direction for improving the efficiency of monitoring projects for such water areas is the use of uninhabited autonomous and remote-controlled underwater robots. However, the use of traditional types of such equipment has low efficiency because of the impossibility of the operational management of the missions of autonomous vehicles in real time and the complexity and high cost of using remote-controlled vehicles.

As an alternative to the robotic support of underwater monitoring projects in shallow water areas, it is proposed to use autonomous underwater vehicles with a radio beacon, since they make it possible to survey large areas, perform high-quality and comprehensive search and mapping work, while providing operators with real-world underwater conditions of time.

A generalized structure and composition of the equipment for an autonomous underwater vehicle with a radio beacon is described, its main underwater missions and types of underwater operations are described.

In order to assess the resources for the execution time of projects for the robotized monitoring of shallow water areas, dependencies are proposed for calculating the time costs for different trajectories of the movement of the underwater vehicle-robot. Using this methodology, time expenses were calculated and the number of underwater vehicle operation cycles for the main ports of Ukraine was estimated during the examination of the mooring walls with video equipment of the underwater vehicle and examination of the shallow water area by its sonar.

The obtained results are a preliminary assessment of the time spent on the study of shallow-water offshore and port water areas, and also form the theoretical basis for the formation of a technical assignment for the creation of modern robotic support for monitoring projects in such water areas.
