Coastal & river engineering
Underwater works


The ETPO Group has its own engineering department dedicated to coastal and river works. The team of engineers works on structural studies, designs special structures and temporary structures and also provides construction methods services. With the latest tools at their disposal for calculations (PYTHAGORE from SETEC, RSA from Autodesk) and data management (VAULT), the engineering department also works with :

  • Autocad, REVIT Structure Suite and INVENTOR from Autodesk for drafting
  • KREA from Terrasol, RIDO from Robert Pages for support structures
  • DUC (internal), TUBA program for mooring dolphins


With a wide range of equipment for coastal and river works, the ETPO Group is constantly present on the three French coastlines as well as in the Overseas Territories and abroad. Specialized floating equipment, heavy equipment but also innovative underwater technologies make up the offshore, coastal and river resources available for our worksites.

Cranes and derricks

Our fleet includes about twenty 18 to 250-ton crawler cranes and one 200-ton derrick. We also have several rubber-tired cranes.

Self-elevating platforms

We have self-elevating platforms with capacities up to 400 tons for construction of mooring dolphins in exposed sites, installation of outfalls, geotechnical surveys, etc.

Barges and pontoons

We have barges and pontoons (modulating or not) on all three French coastlines, the Seine River and in the French overseas territories. They allow us to meet all access challenges in coastal and river works.
