If there’s anywhere we feel at home, it’s underwater! This is reflected by our range of activities: audiovisual inspections and reports, preparation of repair recommendations, and performance of underwater activities under dry conditions using habitats. We also contract for and perform all of the underwater activities involved in civil construction projects, sinking of tunnel units, maintenance and repairs on sluice systems, dams, scaffolding, quay walls, cooling water systems, harbour systems, shipbuilding yards, pipelines, offshore equipment, etc. Furthermore, we perform concrete repairs and assembly activities, construct soil protection systems and repair swimming pools.
OTN has all of the equipment needed to perform underwater activities. For example, decompression chambers, video systems, burning and welding equipment, hydraulic and pneumatic tools, diamond, drilling and cutting equipment, sludge pumps, air lifts, spraying systems, mortar pumps and mixing systems.
