Specific skills in the MRE field

Charier civil engineering has an agency based in Nantes and is an important actor in maritime work in the west.

Recent significant achievements including a part of design:

  • The Fremm pontoon, a design realization:  a reinforced concrete floating structure 160 meters long, 17 meters wide, 8500 tons. It is a work subject to maritime conditions and constraints. The main problem encountered was the important coating and the use of concretes
  • Port of Roscoff – Bloscon: Creation of a new pleasure pool including a rip rap dike of 550 ml in length and the digging of the port by dredging and removal of 120 000m3. Construction of 150 ml of reinforced concrete wharf, reinforced pile-reinforced concrete breakwater, 9 reinforced concrete breakwater pontoons and pile driving (diameter 406 to 1200). More than 20000 m3 of cast concrete.
  • Reinforcement of the water intake dock in Saint-Nazaire: 64 piles, diameter 1020 mm and length 30 to 32 m in a rectangle of 42 m by 27 m. A concrete slab reinforced with a meter of thickness strongly solicited to allow the passage of a convoy of 6500 tons on multi axles

Projects in MRE

Charier leads many reflections currently in partnership with the company CETEAL on the feasibility and the implementation of concrete supports of large sections for tidal turbines:

  • Answering on tenders on the wind farms’ landings in partnership
  • Reflections on anti-scouring implementation operations
  • Supply of Charier quarry materials for the protection of submarine cables
