DEME
Offshore has been awarded three contracts for the Dieppe Le Tréport offshore
wind farm in France. This is the third large-scale offshore wind farm project
for DEME in France following their solutions deployed at Saint-Nazaire
and the recent contract award of Iles d’Yeu and Noirmoutier wind farm.
The contracts cover:-
- The transport and installation of the pin piles and jackets forming the
foundations for the turbines,
- The transport and installation of the pin piles, the jacket and the topside
for the offshore substation.
- The EPCI scope (Engineering, Procurement, Construction and Installation)
for 120 km of inter-array cables.
The Dieppe Le Tréport wind farm is owned
by a consortium made up of Ocean Winds (Engie-EDPR), Sumitomo Corporation
and Banque des Territoires. DEME Offshore believes it was chosen
for its proven track record installing this type of jacket foundations,
its cable laying expertise, and extensive experience of working on offshore
wind farms with challenging site conditions.
According to the Deme press release Dieppe
Le Tréport has similarities to the 950 MW Moray East offshore wind farm
in Scotland, where DEME Offshore performed the full EPCI scope for 100
foundations and three offshore substations for Ocean Winds. Further they
developed their own techniques for this project, which will be deployed
at Dieppe Le Tréport, including a specialised rig and a jacket levelling
and fixation system.
Piling operations for the offshore substation
foundation are set to start in 2024 and the jacket foundation installation
in the following year. One of DEME’s cable installation vessels is set
to perform the cable laying scope, following the installation of the substation.
Dieppe Le Tréport follows the installation
of the XXL monopile foundations at Saint-Nazaire and the contract award
for the installation of monopile foundations and the substation for the
Iles d’Yeu and Noirmoutier offshore wind farm projects. DEME Offshore
has also completed the transport and installation of the offshore substations
of Saint-Nazaire, Fécamp and Calvados.
The
combined contracts represent a ‘large’ contract, which DEME defines as
having a total value of more than EUR 300 million.
