FIELD: machine building.
SUBSTANCE: invention relates to production of works in zone of variable water level at hydraulic structures, such as offshore oil and gas wells, piers, overpasses, walls of discharge channels, dams, bulls, bridge supports, for their repair, cleaning and protection against corrosion and fouling. Device for repair works at various sections of hydraulic structures includes housing and ballast chambers located on outer surface of housing. Housing consists of two detachably connected housing elements, one of which is L-shaped, and the other has U-shape. Device comprises a set of flat detachable elements intended for connection to end surface of housing bottom.
EFFECT: possibility of performing repair works on sections of hydraulic structures of different shape using one device.
