Example of previous works

Urban survey

PURPOSE :
Seabed mapping as part of the docks and urban rehabilitation works

DESCRIPTIVE:
Some 15 kilometers of rivers were mapped in high resolution with multibeam echosounder for detection of navigational hazards but also in the context of a new urban docks and rehabilitation works

Survey inspection

PURPOSE :
High resolution bathymetry and 3D laser scanner with a hydraulic retention before dredging work

DESCRIPTIVE:
Removing all the water from a dam still requires a detailed inspection of the structure to detect the eventual disorders or obstruction which may affect the operation of the pumps but also to estimate the silting of the reservoir before dredging work

Yacht harbour survey

PURPOSE :
Marinas bathymetric survey

DESCRIPTIVE :
Bathymetry survey in a marina allows a multitude of applications results as establishing a anchor plan, volume calculation, object detection on the bottom and disorders of the foot of quay wall…

Sub bottom profilling

PURPOSE :
Bedrock monitoring and determining the thickness of sediment

DESCRIPTIVE :
Coupled with the multibeam bathymetry, sediment survey allows to better understand the geology of an area and provides valuable information for various applications such as environmental studies, the detection of buried objects , dredging …

Underwater pipeline detection

PURPOSE :
Detection and localization of buried piping, positioning and burial measurement

DESCRIPTIVE :
Our means make it possible to locate any pipe or buried structure under the sedimentary layer of the seabed while measuring the thickness of the upper sediment. By multiplying the transverse measurement paths, it is easy to represent the structure or a submarine pipe geographically on a multibeam bathymetry plan.

Underwater driving monitoring

PURPOSE :
High resolution underwater driving bathymetry

DESCRIPTIVE :
The use of very high resolution multibeam sounder makes it possible to obtain an “as-built” visualization of underwater pipes. Our 3D visualizations allow rapid analysis of their condition and surrounding context.
