- in the construction of structures partially placed below water level
- before the beginning of the beach season or the expansion of existing beach boundaries.
Stages of clearing and demining the water area
Cleaning the bottom of the water area (demining) includes:- an on-board sonar and magnetometer survey of the area to determine the presence of large objects and metal accumulations underwater;
- detailing of the ground with probe metal detectors and mapping of detected objects with satellite transmitters;
- diving for direct visual examination of the bottom, collecting small debris and fixing the large to lift it mechanically. If there are explosive objects in the water area they are demined directly on the spot or remotely detonated
- Drawing up a report on the conducted diving survey and bottom cleaning.
Drawing up an act of inspection and cleaning of the water area
The act of diving survey and cleaning of the water area bottom is drawn up on the basis of the technical assignment and the initial data for the works. The act is drawn up after the survey and cleaning of the seabed for foreign objects (including BOP) have been carried out and the results meet all the necessary requirements. The prepared document is approved by all relevant authorities.
