Underwater technicians

All the Nautilus underwater technicians are certified by R.I.NA (Italian Naval Register): "in-water survey of ship and mobile offshore units" and "underwater non-destructive testing of submerged and offshore structures" and by B.V. (Bureau Veritas).

Underwater technicians

Nautilus underwater technicians work with specially designed instruments and equipment to reduce work time to a minimum, to rationalize the diving operations and guarantee the highest safety standards. The divers are constantly in audio and video contact with the surface supervisor, who controls the operations proceed correctly.

The availability of Container hyperbaric chambers, authorized for use on boats, and L.a.r.s. systems (launch and recovery system) for the safe lowering and retrieving of the divers, means operations can be safely conducted even in deep waters and where there are strong currents.
