FEDER Wind PdL

Implementation of nowcasting in the Saint-Nazaire estuary

Project Summary

As part of the Wind PdL project, Oceano Vox is developing a very short-term weather forecasting service (“nowcasting”) for the Loire coast. This service is based on in situ data collected and shared in real time from ships and ports connected via the Weather Vox application. It will enable users and maritime stakeholders (fishermen, boaters, ports, dock operations) to anticipate extreme and hyper-local weather events, thereby improving safety at sea and contributing to the decarbonization of maritime transport.

The project is initially focused on the Saint-Nazaire estuary, with the goal of replicating this service in other ports once it has been validated.

Objectives and Challenges

✓ Address the lack of resources or accuracy in coastal weather observations in the face of increasing extreme weather events
✓ Enhance safety at sea, optimize port operations, and improve the resilience of populations to climate change
✓ Feed statistical models and analyses used by insurance companies and consulting firms with a continuous flow of reliable data

Measures and solutions implemented

The Wind PdL project is based on the establishment of a collaborative sea-land network to build a weather forecasting tool with very high spatial resolution (up to 1 km²), updated every 15 minutes and based on artificial intelligence methods.

This network includes:

  • pleasure craft and work boats equipped with VOX boxes, sailing between southern Brittany, La Rochelle, and the entrance to the Loire (Cordemais, Donges),
  • four ports on the Loire River, equipped with connected stations, ensuring continuity between sea and land for the acquisition and sharing of weather data.

These boxes and stations will enable accurate data to be collected, centralized, and shared in real time, thereby forming the basis for a reliable, hyper-local nowcasting service that can be replicated in other areas.
