Wind energy – drilled monopile
DEME Offshore has successfully installed the first drilled monopile in the Saint-Nazaire offshore wind farm.
Although the first monopile foundations had to be conventionally driven, most of the XL foundations (73 of the 80) at the 480 MW wind farm have to be drilled through challenging calcarenite rock.
For the first time DEME Offshore deploys the Offshore Foundation Drill and tailor-made ‘MODIGA’, a DEME innovation which encapsulates the drilling and installation operations and shields them from the adverse Atlantic marine conditions.
Extending operational working time, the MODIGA is deployed from DEME Offshore’s offshore installation vessel Innovation.
