Technical assistance to engineering (maritime works)

Volume and periodic work control
Through multibeam echo sounder, we calculate the exact volume of dredged or added material, structural bearing volume, temporal variations of natural contributions, etc.

Work management  
Ports, beaches, emissaries, promenades, etc.

Submarine emissaries
Alignment, slope, degree of burying, etc.

Dock, wharf, breakwater inspections with eco sounder and side scan sonar.
We perform very precise digitalisations in 3D, detecting washed-out areas, holes, structural burying, etc., thus enabling engineers to evaluate their size and morphology very accurately.

Diving work and submarine video recording
We set up bottom anchorage, do revisions and visual inspections, recover objects, set up oceanographic material, etc.

Buoy setting
Beaches, fish culture cages, access canals to ports, coastal recreational areas, control and maintenance of buoys already set, etc.

Beach regeneration
We develop projects for the recovery and regenerating of beaches and seaside areas.

Locating sand bars  
Characteristics and quantification.
