Dismantling of structures and sunken objects
Underwater dismantling of hydraulic structures and sunken objects of any complexity: cutting into parts, lifting, clearing the soil.
Dismantling hydraulic structures and sunken objects goes in one order: free the object from the soil, cut it into parts that can be slung, and lift them with pontoons or pulling gear. The cutting method is chosen for the steel, the concrete and the depth.
Cutting underwater
We cut the object into parts that can be slung and lifted.
- Diamond abrasive tool rated 80 kW.
- Electric arc, oxy-arc, exothermic and gas cutting of metal.
- Hydraulic tools on HYKON power packs.
- Cutting reinforced concrete structures.
Lifting and clearing
We lift the parts and clear the site of soil.

Questions and answers
On underwater dismantling
Nothing here? Write what needs dismantling, where and how deep.
Send a requestWhat can you dismantle?
The underwater parts of hydraulic structures, sunken vessels, structures and equipment of any complexity. The cutting and lifting method is chosen for the object.
How do you cut up large objects?
With an 80 kW diamond abrasive tool and underwater metal cutting: electric arc, oxy-arc, exothermic, gas. Reinforced concrete we cut underwater too.
What if the object is silted up?
We wash out the soil with water jets: by ejector down to 10 m, deeper by AirLift.
Do you raise sunken vessels whole?
Where possible, yes. More on Marine salvage.
