Underwater Surface Drone Systems for Inspections and Monitoring ROV AUV USV

Petrov Sky Dynamics, part of Sky Pictures Bulgaria, provides high-tech solutions for inspections, monitoring, and specialized operations in aquatic environments through underwater drones (ROV, AUV) and surface drones (USV – Unmanned Surface Vehicles / remote-controlled boats). These autonomous and remotely operated platforms deliver detailed surveys and analyses of assets and infrastructure in reservoirs, seas, lakes, dams, and port areas, while eliminating risks to human life and significantly reducing operational costs.

What We Offer

Inspection of Water Infrastructure and Facilities

●Surveys of dam walls and reservoirs;
●Inspection of underwater parts of bridges, pilings, and quay structures;
●Inspections of port facilities, vessels, pontoons, and offshore platforms.

Underwater Surveys and Scientific Research

●Observation of seabeds, riverbeds, currents, and sediments;
●Study of ecosystems, marine flora and fauna;
●Monitoring of water quality (pH, salinity, oxygen, temperature);
●Detection of chemical elements present in water bodies.

Industrial and Energy Applications

●Inspection of pipelines, cables, and underwater infrastructure;
●Monitoring of offshore wind turbines and drilling platforms;
