In August 2017, a team of IMSETHC-BAS undertook an inspection and survey of the underwater environment in the area around the water tower of Ognyanovo dam. The team demonstrated the capabilities for inspection and exploration of dam underwater objects, dam dikes and sea beds.

The survey was conducted with a BlueRov2 underwater robot, which is capable of exploring objects and delivering video with 110 degree (horizontal) view angle and quality of 700 TVL in real time in depth of up to 100 meters.

The survey included inspection of the water tower and its foundations and exploration of the remains of a broken bridge linking the water tower and the land.
