Peyrolles-en-Provence Floating Solar PV
Project title: Peyrolles-en-Provence Floating Solar PV
Project location: France
Client: Omexom and Boralex
Project Summary:
INNOSEA, part of OWC, completed independent engineering work to support the design phase of the Peyrolles-en-Provence floating solar PV (FPV) plant – repurposing a decommissioned gravel pit of the same name.
With a projected capacity of 14.7 MWc – enough to power around 6400 homes with green energy, the FPV plant was installed at the site of a disused water gravel pit, converting a large available water body for the production of renewable energy to power the local area.
The plant consists of more than 43000 solar panels installed on a floating structure covering 12.6 hectors and moored with dead-weight anchors.
Our scope of work
- Aerodynamic and environmental loading calculation management
- Detailed mooring and anchoring design
- Mooring installation operation follow-up and validation
Start date: January 2022
Challenges
The appropriate site coupled with competent technical design, is key to mitigating future risk to infrastructure – thereby reducing unforeseen costs in construction, operations & maintenance, and common failures in mooring, float and electrical components.
- Design loads are typically complex to evaluate, as they depend on water conditions and behaviour of the asset in water
- Quarries have lower environmental restrictions and lower environmental loads but a high flood risk
Solutions
- The design and construction of the floating substructure,
- Design and testing of all mounting components: mooring cables and bearings
- Dynamic design load case report
Results
- Innosea is a world-leading specialist in R&D, engineering and advisory for FPV development
- Contributed to over 60 FPV projects in France, USA, Portugal, Maldives, Indonesia, Laos, Brazil and elsewhere
- Expert knowledge of regional or national standards for inshore/nearshore floating structures
“We were really pleased to bring our expertise and track-record in engineering and consulting at the design stage of FPV projects, to the Peyrolles-en-Provence project. This is a project executed in complete compliance with the principle of ‘avoid-reduce-compensate‘ – integrating environmental challenges into the project design for optimised results. Not only that, this project repurposes a large, decommissioned space, for the development of beneficial green energy generation.”
