Cleaning underwater structures and elements

Underwater maintenance to infrastructures and shipping basins, mounting and cleaning lock gates, diving in contaminated waters and cleaning discharge pipes.


To clean the ship hulls and underwater structures, special vapour pressure cleaners are used that eliminate the underwater encrustations on the hulls and submerged parts without damaging the protective paint.

Diving in contaminated waters

Nautilus divers are equipped with sealed diving suits that are not subject to chemical attack, and special equipment for working in contaminated waters. A special after-diving washing system cleans all the contaminated elements to ensure the divers’ health and safety are fully protected.
