French Offshore Wind projects Engineering services

INNOSEA has been in charge of the loads assessments of Wind Turbine and Foundations at Courseulles and Saint-Nazaire wind farms. Monopile foundations, supporting Haliade 150 6MW WTG have been assessed with our structural tools. Calculated loads are used as an input for the structural design of the substructure by Foundation manufacturers later in the Detail Engineering and Fabrication phases. This work has been performed using the aeroelastic software GH Bladed, allowing for the integrated modeling and analysis of the offshore wind turbine.

Tidal turbine foundation design and testing

The aim of this campaign is to assess the loads on the system under combined waves and current, and to compare experimental results obtained with existing numerical loads results, in order to confirm the accuracy and applicability of previous numerical studies performed by Hydroquest. The experimental campaign was carried out at IFREMER test facilities at Boulogne sur Mer (France).

Installation operations engineering

Installation analysis and engineering support activities have been performed for the Baltic 2 offshore wind farm in Germany. The motion analysis of a jack-up barge under different states has been performed for Baltic 2 offshore wind farm. A lifting analysis of Foundations and Transition pieces has been performed. Payload motions have been studied depending on the sea state and on the step of the lifting operation. Engineering support has been delivered succefully for this operation.

Cable layout and stability analysis at Raz Blanchard tidal site

INNOSEA was in charge of the whole basic engineering package for the electrical connection of a tidal pilot plant at Raz Blanchard, involving two tidal turbine technologies. The final objective proposed and evaluated electrical connection scenarios as well as led the RFI / RFQ processes. Those scenarios have been ranked considering associated cost and risks. The most competitive scenario has been considered by the Client for the French tender for pilot tidal plants.

Experimental development and tank testing

For specific projects, INNOSEA has been in charge of the following tasks:

  • Assistance to test campaign definition: definition of the experimental test plan to align with the Client expectations
  • Assistance to scaled model design: scaled model design and measurement & acquisition system procurement and installation.
  • On-site management of the experimental campaign: organization, management and implementation of the experimental test campaign, problem solving and update of the experimental plan if relevant.
  • Post-processing of the experimental results: data treatment, post-processing and analysis of the results, comparison with previous numerical results.
