Material and equipment
The maintenance and continuous improvement of our equipments is the main activity of our workshop based in Fos sur Mer. With a 100 metre long quay and a 3 hectare quayside platform, Negri maintains its fleet of more than 20 units by its own means, ensuring their smooth operation in France and abroad. This infrastructure also allows us to prepare efficiently the logistics of our export operations.
Using this knowledge of this equipment, Negri develops and designs its new tools in order to respond efficiently to the expectations of its customers.

Jack-up platform
A self-lifting pontoon is a floating pontoon equipped with piles mounted on a jack, the piles can go up or down in relation to the pontoon. When the piles are in contact with the seabed, the pontoon can move up and down on the piles until it comes out of the water. This technology makes it possible to carry out work in an agitated area from a fixed platform.
