Nautilus Srl

Nautilus Srl is a leader in industrial diving services and installations both on the land and at sea, of piles and large metal elements.

The company was created in 1996 further to the merger by incorporation of Impremar, which had been operative in Venice since 1979 in industrial diving, maritime and port works. When the company joined the Piacentini Group in 2009 it opened new opportunities for international development.

Since 2010 the new management has been focusing on extending its reference market, by investing in equipment, human resources and innovation and further developing its specialization in maritime work and industrial diving. Today Nautilus is a landmark for State owned and private enterprises. Customer satisfaction is our main goal.
