Our projects

Our know-how in the maritime construction industry allows intervening for the maintenance, extension, or creation of maritime infrastructure. Since the 2000s, we have been operating around the Mediterranean as well as in Africa on commercial ports and quays, military ports, mineral or oil terminals, marinas, and shipyards.

Alone or in partnership, we work on major projects in France and abroad. We are involved in projects ranging from 1 to 100 million euros.

The quality of the projects we design and built, as well as the quality of the relationship we maintain with our clients, lead to a close and trusting collaboration.

The performance and technical characteristics of Negri's self-lifting pontoons allow them to meet the most demanding technical specifications. Modular in the form of caissons or monohulls, the capacities of the self-elevating platforms vary from 80 to 400 tons with surfaces up to 600 m², thus allowing to offer complete and efficient solutions to the specific requests of the customers. They reach exposed sites or sites that are difficult to access by sea or land.
