The growing needs of the Port, in particular to cope with the steady increase in its traffic, have prompted its bathymetric service to equip itself with a new hybrid propulsion cruiser and a modern multibeam bathymetry system.
This set offers many advantages:
In 2019, the Grand Port Maritime de la Rochelle, through a public market, chose the company Cadden for the supply and installation of latest generation hydrographic equipment in order to equip its new hybrid propulsion cruiser (thermal and electric).
In collaboration with the company AluMarine, selected for the construction of this new boat, Cadden was able to provide a complete multibeam bathymetry system with study, integration, installation and training services.
This system includes an R2Sonic 2022 multibeam sounder, integrated directly into the hull, an SBG Ekinox2-I Navsight inertial unit, a hull celerimeter, the Hypack Hysweep software suite for data acquisition and processing and IT (PC and 2 screens).
The equipment offered and the services provided fully corresponded to the expectations of the Port and its hydrographers.
CADDEN also supports the large port of La Rochelle also over the long term with its technical support
In use since early 2020, the R2Sonic 2022 multibeam sounder is proving to be a tool particularly suited to the needs of the Grand Port Maritime de la Rochelle. The resolutions obtained by the multibeam system allow the production of precise bathymetric plans for its users such as the harbor master’s office, port service and dredges.
« In this, Cadden clearly identified the demand for GPMLR during the tender visit. In practice, acquisition times are reduced while data processing is ultimately simpler and safer», says Laurent Chognot, hydrographer at the Port of La Rochelle.

The aim of the Shom was to equip its boats with a rapid survey kit in order to carry out bathymetric reconnaissance surveys on partially surveyed areas.
