Maritime works
Planning maritime works and infrastructures
Planning maritime works and infrastructures

Maritime work requires a fleet, technical divers, specialized staff but, above all, organizational experience and skill. Nautilus works with both planners and its clients in planning the site work, carrying out the structural controls, cost analyses and suggesting alternative solutions to improve the work.

Defence work and dredging
Defence work and dredging

Selective and other underwater digs, for maintenance work or new construction of port structures, or for coastal replenishment. Work to protect coastal areas exposed to the risk of flood and erosion. Studies of the wave motion and marine currents, defining environmental defence projects.

Piles and large metal elements
Piles and large metal elements

Nautilus is specialised in the construction of port infrastructures that require installing metal elements, whether they are used as single elements for constructing moorings (pylons, dolphins), guide structures, signals, or combined together to form complex structures such as quays and mooring, loading and unloading wharves, shipping basins, dry docks, limitation of contaminated sites.

Commercial and marine ports

In laying underwater pipes, electric, telephone and telecommunications lines, Nautilus has developed its own technology that combines all the work for digging, laying and burying the lines into a single phase.

Geognostic campaigns
Geognostic campaigns

For the geognostic campaigns or bed characterization, Nautilus has a modular jack-up platform that can be transported by sea or land. We carry out geognostic surveys at depths between 1.50 and 24.00 meters below sea level. 

Demolitions and restorations
Demolitions and restorations

Demolition of port structures in concrete – below or above the water – and restoration to them using innovative technology and methods (400 bar water jet cleaner with rear thrust for cleaning quays, special platform with integrated drill to support the technical divers working on the restoration work.

Maritime construction work and stabilising marine beds
Maritime construction work and stabilising marine beds

The main field of action for Nautilus is the delicate environment of the Venice Lagoon. Our mission to work in a city built on the water, unique in the world for its historic and architectural wealth, drove us to study low environmental impact solutions and work.

Installing and maintaining buoys and maritime signals
