NDT – measuring the metal thickness by ultrasound device

Diving interventions at ship disasters and accidents at sea

• The evaluation of damage of the sunken vessels
• Taking out and towing of the sunken vessels

Underwater researches, testing and samples collection

Relevant technologies that we successfully use in performing diving works:

• Diving with outer supply and with communication and video link (a surface to a diver)
• Underwater work with hydraulic and pneumatic tools; drills, hammers, diamond saws, grinders, scissors and similar
• Underwater cleaning of surfaces and polishing by a water jet using high-pressure pumps up to 500 bar
• Suction pumps for the underwater digging
• Underwater cutting
• Underwater mining
• Ultrasound probes (sensors) for testing the structures thickness
• Special technologies of chemical sealing and gluing under water

We perform all diving operations with our own diving equipment. Our scuba divers used air, nitrox and trimix diving (gas mixtures).

Wrking vessels:

As a basic boat when performing the works, we use motor boat "JADRIJA" with following dimensions; length=20,5m and width=5,5m, engine Caterpillar 400 HP, speed of 8 NM, with capacity of 15t and for 6 crew members. MB “Jadrija” has been equipped with generators, a hydraulic 4t crane and a loading-unloading ramp.

When necessary, we use additional support vessels of type LANDCRAFT – equipped with their own hydraulic system for lifting and transferring the cargo up to 5 t.
